B. Seasoned Wood  
D. Grate  
Properly seasoned wood is important for successful  
operation of your fireplace. Most woodburning fireplace  
problems are caused by burning wet, unseasoned wood.  
This fireplace is designed to be used with the grate sup-  
plied with this unit or one approved by HHT. The grate will  
break down over time and will need occasional replace-  
ment.  
Seasoned firewood is wood that is cut to size, split and air  
dried to a moisture content of around 20%.  
WARNING! Risk of Fire! Use only the factory-supplied  
integral grate.  
Imagine a wooden bucket that weighs about eight  
pounds. Fill it with a gallon of water, put it in the fireplace  
and try to burn it. This sounds ridiculous but that is exactly  
what you are doing if you burn unseasoned wood.  
•
•
Keeps logs in place.  
Allows proper air circulation around the fire.  
A tree cut down a year ago and not split is likely to have  
almost as high a moisture content now as it did when it  
was cut.  
E. Firescreen  
The firescreen is provided to control sparks. Keep it  
closed when the fireplace is in use.  
Please refer to Section 2.N. for more detail.  
WARNING! Risk of Fire or Burns!  
•
Screen will not prevent burning materials from falling  
out.  
C. Starting a Fire  
•
Screen pulls or handles may be hot.  
NOTICE: You must establish a good draft to prevent smoke  
spillage into the room.  
WARNING! Risk of Fire! Keep combustible materials,  
gasoline and other flammable vapors and liquids clear of  
the fireplace.  
F. Flue Damper  
•
•
Refer to Figure 2.1 for location of control.  
Must be in fully open position (handle up toward the top  
of the fireplace) during operation of the fireplace.  
Before lighting the fireplace, verify fully open position by  
looking up from the inside of the fireplace.  
DO NOT:  
•
•
store flammable materials close to the fireplace  
use gasoline, lantern fuel, kerosene, charcoal lighter  
fluid or similar liquids to start or “freshen up” a fire in this  
fireplace.  
•
WARNING! Risk of Fire and Asphyxiation! Open  
damper prior to operating fireplace. A closed damper  
overfires the fireplace and spills smoke and flames  
into the room.  
Keep all flammable liquids well away from the fireplace while  
it is in use. Combustible materials may ignite.  
•
The first three or four fires should be of moderate size to  
allow the oils and binders to be burned from the fireplace  
and the refractory and paint to cure. You may notice  
an industrial odor the first few fires. This is considered  
normal.  
Use well-seasoned wood (see Section 2.N.).  
Open the flue damper to a fully open position.  
Place crumpled or twisted paper under the fireplace  
grate.  
G. Refractory  
•
The refractory is supplied to contain heat and provide  
an attractive interior.  
•
It will break down over time and will need occasional  
replacement. Small hairline cracks and discoloration are  
normal and do not affect its safety.  
•
•
•
•
(See refractory maintenance Section 3.C.)  
•
•
Loosely arrange kindling or small pieces of wood to form  
a ‘tent’ on the fireplace grate.  
Pre-warm the flue to establish a draft to help reduce  
smoke spillage during start-up. Hold a rolled up piece  
of burning newspaper under the flue damper for a few  
moments.  
WARNING! Risk of Fire! DO NOT burn fireplace with-  
out refractory. Use only refractory supplied by Hearth &  
Home Technologies, Inc.  
•
•
Light the crumpled paper to ignite the kindling.  
Add small pieces of wood until a hot bed of embers has  
been established.  
•
Add a minimum of three average size pieces of split  
firewood, placed to allow combustion air and flames  
between them.  
CAUTION! Odors and vapors released during initial  
operation may be irritating to sensitive individuals.  
Open windows for air circulation.

Hardwood vs Softwood  
Your fireplace performance depends on the quality of the  
firewood you use.  
-
-
Soft wood - about nine months  
Hard wood - about eighteen months  
•
Seasoned wood contains about 8,000 BTUs per pound  
.
•
•
•
Hard woods are more dense than soft woods.  
Hard woods contain 60% more BTUs than soft woods.  
Hard woods require more time to season, burn slower  
and are harder to ignite.  
Soft woods require less time to dry, burn faster and are  
easier to ignite.  
Start the fire with soft wood to bring the fireplace up to  
operating temperature and to establish draft.  
Add hard wood for slow, even heat and longer burn  
time.  
NOTICE: Seasoning time may vary depending on drying  
conditions.  
Storing Wood  
•
•
•
Steps to ensure properly seasoned wood:  
•
•
•
•
Stack wood to allow air to circulate freely around and  
through woodpile.  
Elevate wood pile off ground to allow air circulation  
underneath.  
Smaller pieces of wood dry faster. Any piece over 6 in.  
(152 mm) in diameter should be split.  
Wood (whole or split) should be stacked so both ends  
of each peice are exposed to air. More drying occurs  
through the cut ends than the sides.

•
•
•
•

Pine  
• Oak  
• Maple  
• Apple  
• Birch  
Spruce

•
Store wood under cover to prevent water absorbtion  
from rain or snow. Avoid covering the sides and ends  
completely.  
WARNING! Fire Risk! DO NOT store wood:  
•
•
In front of the fireplace.  
In space required for loading or ash removal.  
Moisture  
WARNING! Risk of Fire!  
•
•
DO NOT burn wet or green wood.  
Wet, unseasoned wood can cause accumulation of  
creosote.  
Processed Solid Fuel Firelogs  
Manufactured firelogs may be used with this fireplace.  
Hearth & Home Technologies Inc. recommends the use of  
UL Classified processed fuel firelogs. Follow the manufac-  
turer’s lighting and safety instructions.  
The majority of the problems fireplace owners experience  
are caused by trying to burn wet, unseasoned wood.  
•
Wet, unseasoned wood requires energy to evaporate  
the water instead of heating your home, and  
Evaporating moisture cools your chimney, accelerating  
formation of creosote.  
Using firelogs may require more frequent chimney inspec-  
tion and cleaning.  
•
Do not poke or stir the logs while they are burning. Use  
only firelogs that have been evaluated for the application  
in manufactured fireplaces and refer to firelog warnings  
and caution markings on packaging prior to use.

B. Chimney Inspection/Cleaning  
A. Disposal of Ashes  
Frequency: At least twice a year during heating season  
or as recommended by a certified chimney sweep  
By: Certified chimney sweep  
Frequency: When they reach bottom of grate  
By: Homeowner  
WARNING! Risk of Fire! Ashes could contain hot em-  
bers.  
WARNING! Risk of Fire! Ignited creosote is extremely  
HOT. Prevent creosote buildup.  
•
•
Place ashes in a metal container with a tight-fitting lid.  
The closed container should be placed on a  
noncombustible floor or on the ground, well away from  
all combustible materials, pending final disposal.  
If the ashes are disposed of by burial in soil or otherwise  
locally dispersed, they should be retained in the closed  
container until all cinders have thoroughly cooled  
Refer to Figure 3.1 to remove/reinstall termination caps.  
Creosote - Formation and Need for Removal  
When wood is burned slowly, it produces tar and other  
organic vapors, which combine with expelled moisture to  
form creosote. The creosote vapors condense in the rela-  
tively cool chimney flue of a slow-burning fire. As a result,  
creosote residue accumulates on the flue lining. When  
ignited this creosote makes an extremely hot fire.  
•
WARNING! Risk of Fire! A chimney fire can permanently  
damage your chimney system and nearby structures.  
In the event of a chimney fire, Hearth & Home Technolo-  
gies Inc. recommends  
•
•
replacement of the chimney, and  
inspection of the adjacent structure to the provisions of  
NFPA Level III inspection criteria.  
The chimney shall be inspected at least twice a year  
during the heating season to determine when a creosote  
buildup has occurred.  
When creosote has accumulated it shall be removed to  
reduce the risk of a chimney fire.

Troubleshooting Guide  
4
Start Fire Problems  
Possible Cause  
Solution  
Can’t get fire started  
Excessive smoke or spillage  
Burns too slowly  
Not enough kindling/paper or no Use dry kindling, more paper. Arrange kindling &  
kindling/paper  
wood for air movement.  
Damper closed/not fully open  
Not enough air for fire to ignite  
Open damper.  
Smolders, sizzles  
Check for restricted cap/shroud.  
Open air kit (if installed).  
Check for flue blockage.  
Pre-warm flue before starting fire (refer to starting  
fire section).  
Check for adequate vent height (refer to chimney  
assembly section).  
Open window below the fireplace towards the  
wind.  
Wood condition is too wet, too  
large  
Use dry, seasoned wood (refer to wood fuel  
section).  
Bed of coals not established  
before adding wood  
Start with paper & kindling to establish bed of  
coals (refer to starting fire section).  
Flue blockage such as birds’  
nests or leaves in termination  
cap  
Have chimney inspected for creosote and cleaned  
by a certified chimney sweep.  
Down draft or negative pressure Do not use exhaust fans during start-up (refer to  
Competition with exhaust  
devices  
negative pressure section).  
Open window below the fireplace towards the  
wind.  
Fire burns too fast  
Extremely dry or soft wood  
Mix in hardwood.  
Mix in less seasoned wood after fire is established  
(refer to wood fuel section).  
No glass doors  
Overdrafting  
Add glass doors to slow down air flow.  
Check for correct vent height; too much vertical  
height creates overdrafting.  
Check location of vent termination (refer to  
chimney assembly section).

B. Design and Installation Considerations  
D. Negative Pressure  
WARNING! Risk of Asphyxiation! Negative pressure  
can cause spillage of combustion fumes and soot. Fire  
must draft properly for safe operation.  
NOTICE: Check building codes prior to installation.  
•
•
Installation MUST comply with local, regional, state and  
national codes and regulations.  
Consult insurance carrier, local building inspector, fire  
officials or authorities having jurisdiction over restrictions,  
installation inspection and permits.  
Negative pressure results from the imbalance of air avail-  
able for the fireplace to operate properly. It can be stron-  
gest in lower levels of the house.  
Causes include:  
Before installing, determine the following:  
•
•
•
Exhaust fans (kitchen, bath, etc.)  
Range hoods  
Combustion air requirements for furnaces, water heaters  
and other combustion appliances  
Clothes dryers  
•
•
•
•
•
•
Where the fireplace is to be installed.  
The vent system configuration to be used.  
Gas supply piping.  
Electrical wiring.  
Framing and finishing details.  
•
•
Location of return-air vents to furnace or air  
conditioning  
Whether optional accessories—devices such as a fan,  
wall switch or remote control—are desired.  
•
•
Imbalances of the HVAC air handling system  
Upper level air leaks such as:  
- Recessed lighting  
C. Draft  
Draft is the pressure difference needed to vent fireplaces  
successfully. When a fireplace is drafting successfully, all  
combustion byproducts are exiting the home through the  
chimney.  
- Attic hatch  
- Duct leaks  
To minimize the effects of negative air pressure:  
Considerations for successful draft include:  
•
•
•
•
Install the outside air kit with the intake facing prevailing  
winds during the heating season  
Ensure adequate outdoor air for all combustion  
appliances and exhaust equipment  
Ensure furnace and air conditioning return vents are not  
located in the immediate vicinity of the fireplace  
Avoid installing the fireplace near doors, walkways or  
small isolated spaces  
Recessed lighting should be a “sealed can” design  
Attic hatches weather stripped or sealed  
Attic mounted duct work and air handler joints and seams  
taped or sealed  
•
•
Preventing negative pressure  
Location of fireplace and chimney  
NOTICE: Hearth & Home Technologies assumes no  
responsibility for the improper performance of the fireplace  
system caused by:  
•
•
•
•
•
Inadequate draft due to environmental conditions  
Downdrafts  
Tight sealing construction of the structure  
Mechanical exhausting devices  
Improper location of the chimney  
•
•
•
•
Basement installations should be avoided  
NOTICE: Hearth & Home Technologies Inc. recommends  
the use of direct vent fireplaces in basements.

E. Locating Fireplace & Chimney  
Location of the fireplace and chimney will affect perfor-  
mance.  
•
Install through the warm airspace enclosed by the  
building envelope. This helps to produce more draft,  
especially during lighting and die-down of the fire.  
Penetrate the highest part of the roof. This minimizes  
the effects of wind loading.  
Locate termination cap away from trees, adjacent  
structures, uneven roof lines and other obstructions.  
Minimize the use of chimney offsets.  
•
•
•
•
Consider the fireplace location relative to floor and ceiling  
and attic joists.  
•
Take into consideration the termination requirements in  
Section 8 and Section 9.  
NOTICE: Locating the fireplace in a basement or in a location  
of considerable air movement can cause intermittent smoke  
spillage from fireplace. Do not locate fireplace near  
•
•
frequently open doors  
central heat outlets or returns  
Recommended Location:  
• Above peak  
• Inside heated space  
Recommended Location:  
• Above peak  
Marginal Location:  
• Wind loading possible  
Marginal Location:  
• Below peak  
Location NOT recommended:  
• Not the highest point of the roof  
• Wind loading possible  
Location NOT recommended:

Keep duct runs short and straight to minimize restriction. A small dip is acceptable for a cold air trap.  
The outside air kit must be installed on the left hand side of the fireplace.  
Locate the air inlet in a clear area, preferably into prevailing wind during the heating season. Refer to Figure 5.2.  
Install as shown in Figures 7.3, 7.4 and 7.5.  
The air duct may be run vertically.  
The outside air inlet must be at least 3 ft (.91 m) below the top of the uppermost chimney section.  
CAUTION! Risk of Fire or Asphyxiation! DO NOT draw outside combustion air from wall, floor or ceiling cavity, or  
enclosed spaces such as an attic or garage.  
• DO NOT place outside air inlet close to exhaust vents or chimneys. Fumes or odor could be drawn into the room

Determine the chimney components needed to complete  
your particular installation:  
A. Chimney Requirements  
Measure vertical distances from the base of the fireplace  
as shown in Figure 8.2.  
•
Measure the total vertical height of the fireplace  
installation from the base of the fireplace assembly to  
the approximate location of the bottom of the termination  
cap.  
Subtract the effective height of the fireplace assembly  
(see Figure 8.2) from the total vertical height to determine  
the overall height of the chimney installation.  
Create a schematic for your application similar to Figure  
8.2 showing components required (referring to Table  
8.1). Figure 8.1 identifies those components and where  
used.

tible materials around the chimney system. Failure to do  
so may cause overheating and fire.  
CAUTION! Risk of Fire and/or Asphyxiation! DO  
NOT connect this fireplace to a chimney flue servicing  
another appliance. DO NOT connect to any air distribu-  
tion duct or system. These actions could cause over-  
heating/fire in the chimney flue, or release of exhaust  
fumes into the living areas.

B. Using Offsets/Returns  
•
•
Use an offset/return to bypass overhead obstructions.  
An offset and return can be used as a single entity or separated by chimney section(s).  
WARNING! Risk of Fire! DO NOT use offset/returns greater than 30°. Chimney draft will be restricted and could cause  
overheating and fire.  
•
•
•
Measure the shift needed to avoid the overhead obstruction. Refer to dimension A in Figure 8.3.  
Find the appropriate A dimension listed in Table 8.2.  
The B dimension coinciding with the A dimension measurement in Table 8.2 represents the required vertical clearance  
needed to complete the offset/return.  
•
Read across the chart to find the number of chimney sections/model numbers needed between the offset and return.  
Example:  
A
Your “A” dimension from Figure 8.3 is 14 1/2 in. (368  
mm). Using Table 8.2 the dimension closest to, but  
not less than 14 1/2 in. (368 mm) is 14 1/2 in. (368  
mm) using a 30° offset/return.  
B
You determine from the table that you need 34 1/8 in.  
(867 mm) (Dimension “B”) between the offset and  
return.  
The chimney component that best fits your applica-  
tion is one SL324.

C. Assembling Chimney Sections  
D. Install Chimney Air Kit  
WARNING! Risk of Fire! DO NOT install substitute or  
damaged chimney components.  
•
•
Required in Canada.  
Follow instructions provided with this accessory.  
•
Use only those components described in this manual.  
Substitute or damaged chimney components could impair  
safe operation and cause overheating and fire.  
E. Installing Ceiling Firestops  
CAUTION! Risk of Fire! Ceiling firestops must be used  
whenever the chimney penetrates a ceiling/floor.  
•
Support the pipe during construction and check to be  
sure inadvertent loading has not dislodged the chimney  
section from the fireplace or at any chimney joint.  
Attach a straight chimney section or an offset to the top  
of the fireplace.  
Place inner flue to the inside of the chimney section below  
it. Place the outer casing outside the outer casing of the  
chimney section below it. Refer to Figure 8.4.  
• Chase construction requires ceiling firestops at  
each floor or every 10 ft (3.05 m) of clear space.  
• The ceiling firestop slows spread of fire and reduc-  
es cold air infiltration.  
•
•
•
•
•
•
•
Install a ceiling firestop whenever chimney penetrates  
ceiling/floor.  
Mark and cut an opening in ceiling as shown in  
Figure 8.5.  
Frame the opening with the same size lumber used in  
the ceiling joists.  
Nail the ceiling firestop to the bottom of the ceiling joists  
when there is a room above.  
NOTICE: Chimney sections cannot be disassembled  
once locked together. Plan ahead!  
•
Lock chimney sections and/or offsets/returns together by  
pushing downward until the top section meets the stop  
bead on the lower section.  
Pull on the top section to make sure it is fully engaged  
and will not separate.  
You may use #6 or #8 sheet metal screws no longer than  
1/2 in. (13 mm) to fasten chimney sections together. Do  
not penetrate inner flue.  
Use an attic insulation shield if the ceiling is insulated.  
The ceiling firestop may then be attached above or below  
the joists.  
•
•
WARNING! Risk of Fire! DO NOT seal area between  
firestop opening and chimney pipe. Restricting air flow  
around chimney may cause fire.  
WARNING! Risk of Fire! You MUST use screws (pro-  
vided) to fasten offset/returns to chimney sections to  
keep the chimney parts from twisting. Failure to do so  
could cause fire.

Chase Installations

Gas line holes and other openings should be caulked with  
high temperature caulk or stuffed with unfaced fiberglass  
insulation. If the fireplace is being installed on a cement  
slab, we recommend that in cold climates, a sheet of  
plywood or other raised platform be placed underneath to  
prevent conducting cold up into the room.  
A. Construct the Chase  
A chase is a vertical boxlike structure built to enclose the  
fireplace and/or its vent system. Vertical chimneys that  
run on the outside of a building must be installed inside a  
chase.  
Construction of the chase may vary with the type of build-  
ing. These instructions are not substitutes for the require-  
ments of local building codes. Local building codes MUST  
be checked.  
Three examples of chase applications are shown in Fig-  
ure 9.2.  
1. Fireplace and chimney enclosed in an exterior chase.  
2. Chimney offset through exterior wall and enclosed in chase.  
3. Chase constructed on roof.  
A chase should be constructed in the manner of all  
outside walls of the home to prevent cold air drafting  
problems. The chase should not break the outside build-  
ing envelope in any manner. All outer walls need to be  
insulated.  
Note: In cooler climates, all chase walls should be insulated.  
Building codes require false ceiling and ceiling firestops  
at each floor of the chase or every 10 ft (3.05 m) of clear  
space to control spread of fire.  
Walls, ceiling, base plate and cantilever floor at the first  
level of the chase should be insulated. See Figure 9.1.  
Vapor and air infiltration barriers should be installed in the  
chase as per regional codes for the rest of the home. Ad-  
ditionally, Hearth & Home Technologies recommends that  
the inside surfaces be sheet rocked and taped (or the use  
of an equivalent method) for maximum air tightness.
