Planning Information
Planning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a fireplace will be set and how the
chimney system will be run.
5. No more than 2 offsets (4 total 30° elbows in U.S./or
2 total 45° elbows in Canada) per fireplace may be
used.
6. A guy wire stabilizer is required for chimneys extend-
ing more than 6’ (1.8m) above a roof line.
Mounting the Fireplace
The Ten Foot Rule
The fireplace is shipped with lifting handles attached to
each side with lifting straps. NOTE: The lifting straps
are intended for ligting unit off of the skid and final po-
sitioning. Unit should remain on skid until final position-
ing. After fireplace is in position, the lifting handle and
straps may be removed or left in place.
Major U.S. building codes specify a minimum chimney
height above the roof top. The “Ten Foot Rule” is a fire
safety rule and not a draft rule. To ensure proper draft,
it is recommended that you always meet or exceed the
“Ten Foot Rule,” especially when installing a termination
on a high pitch roof. (Fig. 5)
A fireplace may only be mounted on the following sur-
faces:
The key points of the “Ten Foot Rule” are:
1. A flat combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneath
each of the four (4) corners of the fireplace.
1. If the horizontal distance from the chimney to the
peak of the roof is 10’ (3m) or less, the top of the
chimney must be at least 2’ (610mm) above the peak
of the roof, but never less than 3’ (914mm) in height
above the highest point where it passes through the
roof.
The fireplace must be spaced 1” from a combustible
back wall and 1” from a combustible side wall or sup-
2. If a horizontal distance from the chimney to the peak
of the roof is more than 10’ (3m), a chimney height
reference point is established that is on the surface
of the roof a distance of 10’ (3m) from the chimney in
a horizontal plane. The top of the chimney must be
at least 2’ (610mm) above the reference point, but
never less than 3’ (914mm) in height above the high-
est point where it passes through the roof.

Reference
Point
AC246
In planning a chimney system, it is important to know:
1. The height of a chimney is measured from the hearth
to the exit point on the termination.
Fig. 5 Ten Foot Rule illustration.
2. A chimney cannot be offset more than 30° from a
vertical plane.
3. A chimney may run straight up or it may be neces-
sary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney
system) is 20 feet.

Chimney Supports
Installation
The chimney system is supported by the fireplace for
vertical chimney heights less than 30’ (9m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30’ (9m). Locate chimney supports
at ceiling holes or other structural framing at 30’ (9m)
heights. Spacing between chimney supports must not
exceed 30’ (9m). Use Chimney Support Model SKCS8.
(NOTE: The SKCS8 cannot be mounted directly to
the fireplace.) Support provided by elbow straps fulfills
the support requirement only if they are spaced as pre-
viously described. (A chimney support is 2¹⁄₂" (64mm)
long when installed.)
Insulating Fireplace Enclosure
for Cold Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate fireplace
enclosure to eliminate cold air penetration as much as
possible.
Insulate base of fireplace with a noncombustible
insulation rated for a minimum of 300° F. Insulating
is very important for outside wall installations over
a concrete slab. If fireplace is installed on a platform,
insulation should be placed on top of the platform
before fireplace is set. (Fig. 7)
Angled chimney runs require a support every 6’ (1.8m)
in addition to the elbow straps. Chimney supports are
used for this function. (Fig. 6)
When a fireplace is installed in a chase or on an
outside wall, enclosure should be treated like any
outside wall in a home. Insulation should be installed
on the inside wall as well as the outside wall(s). In a
chase, it is also a good idea to install a firestop at the
first ceiling level above the fireplace and enclose the
chase with sheeting material. Insulation may then be
installed above sheeting material to assure the space
around the fireplace is totally protected. (Fig. 2)
Chimney Sup-
port Strap
When installing the chimney, DO NOT caulk between
outer pipe and firestop. It is vital that some air be al-
lowed to flow through this very thin gap.
TCS8A
CAUTION: When installing a fireplace in an insu-
lated enclosure, be sure all required air spaces
are maintained. (Page 13, Fig. 17)
FP284a
Fig. 6 Chimney support installation.
Chase Installation
A chase is a vertical box-like structure which encloses
the fireplace and/or chimney. Chases are typically built
on the outside of the house with fireplace opening cut
into the outer wall of a room. (Page 5, Fig. 2)
If you need help in determining fireplace location or how
the chimney system should be run, contact your Ver-
mont Castings dealer for assistance.

Framing
Chimney Centerline
Actual Centerpoint
Framing can be constructed before or after the fireplace
is set in place, however, most installers build the frame
before setting the fireplace.
9���"

Frame fireplace with 2 x 4 lumber or heavier materi-
als. Refer to framing dimensions in Figure 1 for basic
fireplace specifications.
NOTE: Framing should be positioned to accommodate
wall covering and fireplace facing material.
Plumb Line
Plumb Bob
EB1 (Receptacle) Hookup
Option for Circulating Models Only
Wiring should be installed by a certified electrician.
Turn off circuit breaker before wiring models.
Imaginary
Centerpoint
Once fireplace is secured, complete wiring the fan kit.
Remove knockout in the center of the back of the EB1
and install listed cable clamps. Feed electrical wire
through listed cable clamp leaving approximately six (6)
inches of wire exposed through the EB1. Secure listed
cable clamp to the wire.
Attach white wire from power source to one (1) wire
of receptacle and secure with nut. Attach black wire
from power source to the other wire of receptacle and
secure with nut. Be sure nuts are secured tightly.
Secure EB1 assembly to inside of electrical box cover-
plate using two screws. Attach cover to face of the EB1
while being careful to position excess wire completely
within the EB1, then attach coverplate to fireplace.
Chimney Set-Up
Since you have already planned the chimney run, you
should know exactly how the installation is to be ac-
complished - how much pipe is required, the number of
elbows, if any, and type of termination to be used.
FP1563
Fig. 8 Locate centerline of chimney with plumb line.
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 8)
CAUTION: Report to your dealer any parts damaged
in shipment, specifically check the end connection of
chimney sections and elbows.
Offset Installation
NOTE: Fireplaces may use CFM Corporation Model
SK8, or Model S (three wall) chimney systems. The
BR/BC Series Fireplace will accept the SK8 chimney
system as is; but a TWABR adapter collar is required
when using the Model S (triple wall) chimney system.
The installation procedure described in this manual
applies only to the SK8 system. Either chimney system
may be used, but may not be mixed.
In order to clear an obstruction, it may be necessary to
offset chimney from vertical. This is accomplished by
using elbows. Use the 30˚ Offset Elbow table on Page 6
to determine proper offset and parts required.
Each offset requires two (2) elbows. The second elbow
is equipped with support straps. It is very important to
install the second elbow in each offset as close to the
ceiling or support as possible so that the elbow straps
can be secured to framing members to help support the
weight of the chimney.
Straight-Up Chimney Installation
To mark the centerline of the flue, put the fireplace
in final position and measure out from the wall: 9¹⁄₂"
(241mm). Mark a spot on the ceiling directly above the
fireplace. Draw a line parallel to the back wall through
this mark. (Fig. 8)
Determine offset distance of your chimney arrangement
from centerline of fireplace to centerline of chimney
where it is to pass through ceiling.

Safety strips are used to ensure that any combustible
materials in front of the fireplace are protected even
though a noncombustible hearth extension is required.
Four (4) nailing flanges are supplied with the fireplace

codes mandate the use of an air kit, then an AK-MST
is required to complete the installation (from air kit to
the outdoors). If the outside air kit is to be used, the
AK-MST MUST be installed BEFORE the fireplace is
enclosed.

permissible.)
Installation Precautions
The duct termination should be located so it is exposed
to an out-of-doors opening at least 100 square inches. If
the duct termination must be located in a crawl space or
basement, be sure the termination area has 100 square
inches of ventilation opening to outside air.

The duct termination must be located so it does not
compete for air flow with exhaust fans, gas vent hoods
or other air consuming devices or appliances. It must
not be obstructed by rafters, insulation materials or
other obstructions. The less restrictive the air supply,
the better the AK-MST will perform.

Installing the Chimney System
Start by attaching the first chimney section to the collar
on top of the fireplace.
Fig. 16 Attach straps to a structural framing member.
Installing the Firestop Spacer
in the Ceiling Hole
Install the pipe as pictured in Figure 15. When you
get a good lock, you will hear the pipe clearly snap
together. Once sections are snap-locked in place, it is
extremely difficult to get them apart. Make sure the
pipe is firmly snapped and locked together as each
pipe section is mounted.
A firestop spacer is used to keep pipe spaced properly
and required for safety.
Nail the firestop spacer (at each corner) to the framing
members of the ceiling hole. NOTE: A firestop spacer
is not required at the roof.
When installing elbows, only outer pipe will snap- lock.
Middle pipes simply slide into position. Be sure to
always attach straps on upper elbow to a structural
framing member. (Fig. 16)
Hole sizes listed in Figure 9 for angled firestop spacers
provide minimum required air space to chimney pipe for
ceiling thickness up to 8” (203mm). When combined
thickness of ceiling material, ceiling joists and flooring
material exceeds 8” (203mm), adjustments must be
made in framing to assure that minimum air spaces to
chimney are maintained.
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer.
Proper Firestop Spacer Installation

Locate Chimney Centerpoint on Roof
In Canada, an attic insulation shield is required to pre-
vent attic insulaiton from contacxting the chimney sec-
tion. Framing dimensions for the chimney hole should
measure 14¹⁄₂” x 14¹⁄₂” (368 x 368 mm). An attic shield
MUST be installed on top of attic joists (above the floor
level). (Fig. 18)
Use same procedure detailed in locating center point of
the flue system.
Drive a nail up through roof at the center point. This will
determine center point on outside of the roof.
Cut and Frame Roof Hole
Continue Installing Pipe to Complete Run
Size of roof hole varies with the type of chimney ter-

provided with CFM Corporation chimney termination to
find correct size of roof hole.
Continue attaching pipe sections to complete system
to next level always being careful that the pipe is firmly
snapped locked in place before proceeding to next pipe
section.

There must be a 1¹⁄₂” (38 mm) air space between out-
ermost portion of chimney sections and any adjacent
combustible surfaces. (Combustible surfaces include
burnable materials such as: ceiling members, joists,
flooring, combustible insulation and roof structures.)
Finish Wall
Finish the wall with material of your choice. Do not
install a combustible mantel shelf less than 12”
(305 mm) above the firebox grille opening. Do not
install a mantel face plate less than 6” (159 mm)
from top of grille opening. (Fig. 21) If a combustible
material is used below a flat mantel shelf, consult your
local building codes for minimum clearance from top of
fireplace opening to bottom of mantel shelf.
WARNING: Do not pack required air spaces with
insulation or other materials.
Mark an outline of the roof hole around the center of the
point nail. NOTE: Hole dimensions given in the chim-
ney top installation instructions are horizontal dimen-
sions; therefore, the hole size must be marked on the
roof accordingly.
All joints (top, bottom and sides) where wall or decora-
tive facing material meets fireplace surround must be
completely sealed with a noncombustible material. (Fig-
ures 20 and 24)
Cover the opening of the installed chimney so debris
cannot get into the system.
NOTE: No side wall protection is required for fireplaces
installed at 45° to two (2) side walls (corner installation).
Cut and frame the hole. It is good practice to use fram-
ing lumber that is the same size as the rafters. Install
the frame securely because the chimney top and flash-
ing anchored to the frame must be able to withstand
heavy winds.

Mantels
Side Wall Protection
The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.
Adjacent combustible side walls that are within mini-
mum dimensions shown in Figure 24 of the fireplace
opening must be protected with CFM Corporation Wall
Shield Model SP40 or a specifically built wall shield
described in Figure 19.
For the correct mounting heights and widths, refer to
Figures 21 and 22. When using paint or lacquer to finish
the mantel, such paint or lacquer must be heat resistant
to prevent discoloration.
The special wall shield design described in Figure 19 is
an alternate method of adding protection to side walls
and can be used in place of the SP40 with the same
wall clearances specified for the SP40. Rt must =1.85

Assemble the primary air control and damper handles
by passing the screw through the wood shaft and into
the bright metal hub. Tighten carefully until snug. Do not
overtighten. Wood handle could crack. (Fig. 27)

FP1568
Fig. 26 Insert fallaway handle into door handle stub.
Generally, more air entering the fireplace makes the fire
burn hotter and faster, while less air prolongs the burn.
The air supply is open to the maximum when the control
lever is pushed down, and closed when pulled up. To
vary the burn rate, adjust the control to the desired posi-
tion in between these extremes; opening the primary air
control makes the unit burn hotter. Closing the control
slows the unit down. You may adjust to any position you
desire.

The damper is operated by moving the lever located in
the upper right corner of the unit. It has two positions:
Open to start or revive the fire and closed, for normal
operation and to control burn rate. The damper is open
when the lever is pulled out and closed when pushed in.
There are no intermediate settings for the damper.

EWF30 Controls
Three controls regulate the performance of the EWF30
fireplace: A primary air control supplies oxygen for the
fire, the damper directs air flow within the fireplace and
a variable-speed fan control, or rheostat, regulates the
warm air flow into the room. (Fig. 28)
NOTE: Always open the damper before opening the
doors. Close damper to set burn rate.
Primary Air Control
A single air control regulates the amount of heat the fire
will produce and how long it will burn.

Vermont Castings EWF30
Use the Air Control Settings
The Fan
that Work Best for You
Heated air from the fireplace is forced into the room by
an internal fan. The control for the fan is in the right
corner of the unit.
No single air control setting will fit every situation. Each
installation will differ depending on the quality of the
fuel, the amount of heat desired, and how long you wish
the fire to burn.
“Off” is to the far left. (counterclockwise
“High” is just to the right of “Off.”
“Low” is to the far right. (clockwise
)
)
The control setting also depends on your particular
installation’s “draft,” or the force that moves air from
the fireplace up through the chimney. Draft is affected
by such things as the length, type, and location of the
chimney, local geography, nearby obstructions, and
other factors.
Variable adjustment of the fans is possible with any set-
ting between “high” and “low.”
For best results, coordinate fan speed with the setting
of the primary air control. For example, when the air
control lever is set at “low,” also set the fan at “low.”
With the air control set for maximum heat, set the fan at
“high.”
Too much draft may cause excessive temperatures
in the fireplace. On the other hand, too little draft can
cause backpuffing into the room and/or the “plugging” of
the chimney or combustor.
Glass Doors
How do you know if your draft is excessively high or
low? Symptoms of too much draft include an uncontrol-
lable burn or a glowing-red part of the EWF30 front. A
sign of inadequate draft is smoke leaking into the room
through the fireplace or chimney connector joints, low
heat, and dirty glass.
The EWF30 is intended for use with the doors fully
closed or fully open only when optional spark screen
is installed. (Fig. 29) NOTE: When operated with the
doors open and spark screen in place, the damper
MUST be in the open position.
In some newer homes that are well-insulated and
weather-tight, poor draft may result from insufficient air
in the house. In such instances, an open window near
the fireplace on the windward side of the house will
provide the fresh air needed.
Optional
Spark

Another option for getting more combustion air to the
fireplace is to duct air directly from the outside to the
fireplace. In fact, in some areas provisions for outside
combustion air are required in all new construction.

Fig. 29 Correct door position during operation.
Burn Only High-Quality Wood
Your EWF30 is designed so that it is possible to incor-
porate outside air for combustion. Directions for install-
ing the optional AK-MST outside air duct is included
with the kit and beginning on Page 11 of this instruction.
The EWF30 is designed to burn natural wood only; do
not burn fuels other than that for which it was designed.
You will enjoy the best results when burning wood that
has been adequately air-dried. Avoid burning “green”
wood that has not been properly seasoned.
When first using the fireplace, keep track of the settings
of the air controls. You will quickly find that a specific
setting will give you a fixed amount of heat. It may take
a week or two to determine the amount of heat and the
length of burn you should expect from various settings.
The best hardwood fuels include oak, maple, beech,
ash, and hickory that has been split, stacked, and air-
dried outside under cover for at least one year.
For areas that do not have a supply of hardwood, com-
monly burned softwoods include tamarack, yellow pine,
white pine, Eastern red cedar, fir, and redwood. These
too should be properly dried. Your EWF30 will accept
wood up to 23” (584 mm). Longer wood pieces work
better than short ones.
Most installations do not require a large amount of
combustion air, especially if adequate draft is available.
Do not for any reason attempt to increase the firing
of your heater by altering the air control adjustment
range outlined in these directions.
Wood should be stored under cover to maintain dry-
ness, and should be dried at least six months for
optimum heating and fire-viewing performance. Even
for short-term storage, however, keep wood a safe
distance from the heater and keep it out of the areas
around the heater used for refueling and ash removal.

5. Once a good ember bed of at least 2-3” (51-76 mm)
has formed, let the fire burn hot for an additional ten
to fifteen minutes.
Starting and Maintaining a Wood Fire
Burn solid wood fuel only in the EWF30, and burn it
directly on the grate. Do not elevate the fuel. Do not
burn coal or other fuels.
6. Close the damper and the primary air control to a
medium-low setting as described on Page 18. The
fire volume will diminish immediately, but the fire-
place will continue to heat up. Maintain control of
the fire using the primary air control, and remember:
reduce the setting for less heat, increase the set-
ting for more heat. Refer to the air control settings
information on Page 18 for recommended settings at
different burn rates.
Minimize thermal stress by allowing the plates to adjust
gradually during an initial break-in fire by following
Steps 1-3 below.
WARNING: Operate your EWF30 only with the
doors fully closed. If the door is left partially open,
gas and flame may be drawn out of the fireplace
opening, creating risks of both fire and smoke.
1. Open the primary air control fully.
2. Open the damper.
DO NOT OVERFIRE THIS HEATER. Overfiring may
cause a house fire, or can result in permanent damage
to the fireplace. If an exterior part of the EWF30 glows,
you are overfiring.
3. Lay some crumpled newspapers on the bottom
grate. Place on the paper six or eight pieces of dry,
finely-split kindling. On the kindling lay two or three
larger sticks of split dry wood approximately 1-2”
(25-50 mm).
Reloading and Reviving a Wood Fire
• Open the damper and set the air control on “High,”
and wait at least fifteen seconds for the draft to
increase. Open the door slowly.
Do not use chemicals or fluids to start the fire. Do
not burn garbage or flammable fluids such as gaso-
line, naptha, or engine oil.
• Check the ash level, and empty the ash pan if nec-
essary. Replace the pan.
Also, never use gasoline-type lantern fuel, kerosene,
charcoal lighter fluid, or similar liquids to start or “fresh-
en up” a fire in this heater. Keep all such liquids well
away from the heater while it is in use.
• Add the fuel, smaller pieces first. If it is necessary
to use wood smaller than the 23” (584 mm) opti-
mum size, be sure to fill the firebox as completely as
possible by loading the wood pieces alternately on
the left and right. Split wood will fill the firebox more
completely and reduce the frequency of reloading.
4. Light the newspaper and close the door. Gradually
build up the fire by adding a few 3-5” (80-120mm)
diameter splits.
If you have an ember bed of at least 2-3” (51-76 mm),
leave the air control set on “high” for 10-15 minutes. If
the ember bed is less than 2-3” (51-76 mm), you may
have to let it burn longer. Also, depending on the quality
of your wood, the temperature of the firebox and the
draft conditions of your chimney, it may be helpful to
leave the door cracked open for up to 5 minutes. This
will help to ignite freshly loaded wood. NEVER leave
the fireplace unattended unless the door is completely
closed. Overfiring could result from leaving the door
cracked open.
If this is your initial break-in fire, let the fire burn brightly,
but not to excess. Control the fire’s intensity by adjust-
ing the air control lever. After an hour or so stop adding
wood so that the fire dies out gradually.
For ongoing operation after the initial break-in, continue
to add a few sticks at a time of a progressively larger
size. Continue until you have a live ember bed at least
2-3” (51-76mm) deep. This may take an hour or longer.
CAUTION: THE EWF30 IS HOT WHILE IN OPERA-
TION! KEEP CHILDREN, CLOTHING, AND FURNI-
TURE AWAY. CONTACT MAY CAUSE SKIN BURNS.
Finally, close the damper and adjust the air control and
fan speed for your desired heat level.
NOTE: Some chimneys need to be “primed,” or
warmed up, before they will draw sufficiently to open
the damper. To correct this situation, roll up a couple
pieces of newspaper, place them on top of the kindling
and toward the back of the fireplace, light them, and
close the doors. This should heat the chimney enough
to initiate a draft.
NOTE: If the charcoal bed is relatively thick and your
fuel is well-seasoned, it is possible to add fresh fuel
(smaller pieces first), close the door and damper, and
reset the air control within five minutes.
Special Tactics for Cold-Climate Heating
The EWF30 is capable of producing in excess of
55,000 Btu’s/hour and heating an area of up to 2,400
sq. ft.(223 sq. m) However, many factors affect heating
performance and can influence the extent to which the
EWF30 can heat a given area.
Once the draft is established, open the front door and
light the rest of the fuel from the bottom. Do not light the
main bed of fuel until the chimney begins drawing, and
repeat the procedure as often as necessary if the initial
attempt is unsuccessful.

A well-insulated home, located in a moderate climate
and with the EWF30 Fireplace located centrally in an
open floor plan, will be easier to heat than a drafty
home in the far north in which the EWF30 is installed on
an exterior wall at the end of a long house.
•
•
Take the pans outdoors and empty the ash into
an ash container.
Before replacing the ash pan, clear away any ash
that has spilled over the sides and back of the
pan.
•
Replace the ash pans and front door.
Different results may be experienced even in the same
installation if you switch from burning good, dry wood to
wood that is partially rotted or inadequately seasoned.
Empty the ash pans regularly, typically every one to
three days. The frequency will vary depending on how
you operate your EWF30: If you burn more wood at
higher heat output settings, and ash will accumulate
faster.
To compensate for these factors in cold climates, it may
be necessary to operate the EWF30 with the air control
set to a higher level more of the time.
Ash should be removed frequently and placed outdoors
in a metal container with a tight-fitting lid. The closed
container of ash should be placed on a noncombustible
floor or on the ground, well away from all combustible
materials, pending final disposal. If the ash is disposed
of by burial in soil or otherwise locally dispersed, it
should be retained in the closed container until all cin-
ders have thoroughly cooled. Wood ash may be used
as a garden fertilizer.
Remove and Store Ash Safely
Check the ash pan before reloading the fireplace, and
empty if necessary using the following procedure:
•
•
•
Open the damper.
Open the load door.
Remove the ash pans from under the hearth
brick. CAUTION: Ash may contain hot coals and
must be treated with extreme care. Hold the ash
pan with both hands to avoid dropping or spilling
the ashes.
CAUTION: Never use your household or shop vacuum
cleaner to remove ash from the fireplace; always re-
move and dispose of the ash properly.

Maintenance
Keep your EWF30 Fireplace Looking New
and Working Its Best
Pawl
Small Lock-
ing Nut
Care of the Cast Iron Surface

An occasional dusting with a dry rag will keep your
EWF30 fireplace looking new.
Large
Locking Nut
If the paint needs retouching, first allow the surface
to cool completely. Wire-brush areas needing to be
painted. Touch-up with high temperature fireplace paint
available from your local dealer. Apply the paint spar-
ingly. Two light coats are better than one heavy one.

Cleaning the Glass

The EWF30 glass system requires a minimum amount
of cleaning. Most carbon deposits that accumulate will
burn off during hot fires.

latch.
tance, the gasket isn’t snug enough at that spot. Con-
tinue to make small adjustments until the setting is right.
Ash residue that accumulates on the glass should be
removed periodically to prevent etching. To clean the
glass, follow this procedure:
If additional adjusting of the latch does not enable the
door to seal sufficiently in one area, try “adjusting” the
gasket in that area. Pack more cement or a smaller
diameter gasket into the channel beneath the gasket so
that the main gasket is raised and makes contact with
the door frame. This procedure should solve the prob-
lem. If the gasket needs replacing, follow the directions
beginning on Page 23.
•
•
Be sure the glass is completely cool.
Cleaning with water will work in most cases. Use
a glass cleaner especially made for this purpose
only if deposits are especially heavy. (If heavy
deposits are a frequent occurrence, however,
evaluate your operating techniques.)
•
•
Rinse the glass thoroughly.
Dry the glass completely.
How to Replace Gaskets
The EWF30 uses rope-type fiberglass gaskets to make
a tight seal between some parts. With use, particularly
on those parts that move, gaskets can become brittle
and compressed and can begin to lose their effective-
ness. These will need periodic replacement.
NOTE: The EWF30 glass is coated with a special
material on the outside that helps reflect heat back
into the fire chamber. Do not attempt to remove
this coating.
All of the gaskets used are made of fiberglass. The four
sizes of replaceable gasket are listed below, along with
their application.
Adjust the Door Latch Periodically
The front door of the fireplace should close securely to
prevent accidental opening and should close tightly to
prevent air from leaking into the fire chamber. The door
handles will be positioned vertically when the door is
closed.

Gasket Size...
...And The Parts It Seals

The door to the front
The glass seal to the door
Damper to top plate
Over a period of time, the gasket around the door will
compress and the latch may need adjustment. To ad-
just the handle, follow this procedure (Fig. 30):
Should you need to change a replaceable gasket, wait
until the fire is out and the fireplace has cooled. Be
sure to follow the standard safety procedure for work-
ing with dusty materials: Wear safety goggles and a
dust mask. The procedure for replacing gaskets is the
same, regardless of the gasket location. Four easily-
accomplished steps are involved:
1. Loosen the small lock nut with a wrench.
2. Extend the striker screw one turn by turning it with
an Allen wrench.
3. Retighten the lock nut, while at the same time hold-
ing the striker screw with the Allen wrench to prevent
its turning.
Test the door seal. Close the door on a dollar bill and
attempt to pull it free. If the bill is freed with little resis-

1. Remove the existing fiberglass gasket by grasping
an end and pulling firmly.
The Chimney System
2. Use a wire brush or the tip of a screwdriver to clean
the channel of any remaining cement or bits of gas-
ket.
A Clean Chimney System is
Safer and Works Better
Although the combustion system in the EWF30 can re-
duce creosote formation dramatically, it is not a substi-
tute for regular inspection and cleaning of the chimney
and chimney connector.
3. Apply a thin bead of fireplace cement to the newly-
cleaned groove.
4. Pack a new gasket into the groove. Wait until you
have placed all but a couple inches from the end
before you trim the end to an exact fit.
Learn to Recognize —
and Avoid — Creosote
5. Place door back on fireplace, latch door and keep
closed for 1/2 hour to insure cement has set.
The EWF30 has been designed to reduce creosote
build-up significantly. However, regular chimney in-
spection and maintenance must still be performed. For
safety, good fireplace performance, and to protect your
chimney and chimney connector, inspect your chimney
and chimney connector on a regular schedule. Clean
the system if necessary. Failure to keep the chimney
and connector system clean can result in a serious
chimney fire.
Replacing the Door Gaskets
Remove the door by lifting it straight up off its hinge
pins. Lay it face down on a padded surface.
Follow steps 1-4 as described above.
Replace Damaged Door Glass Immediately
Do not operate the fireplace with damaged glass door.
Use the following procedure for glass replacement.
When wood is burned slowly, it produces tar, organic
vapors and moisture which combine to form creosote.
The creosote vapors condense in the relatively cool
chimney flue of a slow-burning fire. As a result, creo-
sote residue accumulates on the flue lining. When ignit-
ed, this creosote makes an extremely hot fire within the
flue system that can damage the chimney and overheat
adjacent combustible material. If a significant layer of
creosote has accumulated —1/8” (3mm) or more — it
should be removed to reduce the risk of a chimney fire.
NOTE: Replace glass only with the replacement glass
made for this unit, available from your authorized
dealer.
• Remove the door and loosen the retaining clips which
hold the glass to the door frame. Remove clips. Use
caution when handling broken glass.
• Examine the gasket that seals the glass to the door
frame. Replace if necessary with gasket obtained from
your local Vermont Castings’ Authorized Dealer. See
the directions for gasket replacement on Page 23.
If you do experience a chimney fire, act promptly to:
•
Close the primary air control lever and the
damper
Get everyone out of the house.
Call the Fire Department.
• Check the flat surface of the door frame, and clear
away debris if necessary.
•
•
• Install the new glass.
• Secure the clips, being careful not to overtighten. Be
sure the glass is firmly seated against the gasket.
You should inspect the system every two weeks during
the heating season as part of a regular maintenance
schedule. To inspect the chimney, let the fireplace cool
completely. Remove the termination top. Then, using a
strong light, sight down into the chimney flue.
• Replace door.
Clean the chimney using a specially designed brush
the same size and shape as the flue liner. Flexible
fiberglass rods are used to run the brush up and down
the liner, causing any deposits to fall to the bottom of
the chimney where they can be removed through the
damper on top of the fireplace.
If you can not do the chimney inspection yourself, con-
tact your local Vermont Castings’ Authorized Dealer, or
engage a professional chimney sweep to perform the
inspection and cleaning of the chimney.
