A
moisture content of 15% to 20% (seasoned)
is recommended. Wood that has been cut and
split and let to dry under a cover for a period
of one year will usually meet that criteria. The
required drying time will vary depending on the
climate. Wood that is packed tight together will
take longer to dry. Seasoned wood is darker in
colorthanwetwoodandwillhavevisiblecracks
in the grain on the ends. Excessively wet wood
will be difficult to burn and will result in lower
efficiency,increasedcreosotinganddepositson
the glass and in the chimney. Excessively dry
wood will burn well but will also have higher
emissions and shorter burning time.

the left side. The main source of air (primary
air) entering the firebox can be diminished by
moving the air combustion control from left
to right. The primary air is fully opened when
the air control is completely moved to the left.
The air control device can also be used to add
an extra boost of air especially during fire start
up and reloading of the unit.
For instance, a long chimney will necessitate
closing the damper more. To obtain the proper
combustion,closethedampercompletely,then
open it about 1/4” to 1/2”. Three medium size
pieces of wood should be burning on a bed of

the control can be pushed in to shut down the
air boost allowing for a longer burn time. The
combustion air control should be in the closed
position (primary air and air boost) when the
fireplace is not in use. This will minimize air
leakage up the chimney. The combustion air
control should be opened before opening the
door to minimize the possibility of back draft
coming into the room.

adding wood to your fireplace.
Slow Combustion
When the air combustion control is completely
closed,thefireplaceisinaslowcombustionphase.
If the hearth is hot enough, slow combustion will
not extinguish the fire, but there will be a notice-
able change in the flame pattern. The flames will
be slow and may appear dirty if the wood is too
wet (moisture content of 20% and more). Do not
allow the wood to burn without flame, since this
will produce excessive creosote in the unit.

kindling so that there are air spaces in between.
Keep the fuel far back enough so that air can
get underneath. Open the air controls fully
and light the newspaper. Once the newspaper
and the kindling is well ignited, close the door.
Once the kindling fire is well established, cord
wood can be added (see Primary Air Combus-
tion Control section for proper operation of the
air controls).
Accelerated Combustion
Creosote may accumulate on the glass door.
This method of burning should be used only
after operating the Montecito fireplace with
the air control opened to produce a hot fire for
about an hour or at medium pace for at least
three (3) hours. Slow combustion can be used
at night in order to reduce the heat output and
to prolong the burn. The loading time will be
between 6-8 hours.
The maximum heat output for the Montecito
fireplace is achieved by burning with the door
closed and the combustion air opened and
pulled out. By this method, the Montecito
fireplace can produce up to 55,000 BTU of
heat per hour. However, it will be necessary
to reload with wood every one or two hours.
This is the least efficient method of burning the
Montecito fireplace.
REFUELING FOR BEST PERFORMANCE
The Montecito fireplace will operate best if at-
tention is given to operating the unit with the
damper fully opened after refueling in order
to bring the firebox and the chimney system
up to their optimum operating temperature.
Combustion efficiency is relative to firebox
temperature. A temperature of 500º C (932º F)
and up, with a visible flame, in the upper part
of the firebox indicates a maximum efficiency.
To obtain this temperature, the fireplace must
be operated with the primary air and air boost
controls fully opened during 10 to 20 minutes
after reloading, depending on the heat and on
the moisture content of the wood.
The unit will burn best with 2-3 pieces of cord
wood spaced 1 to 2 inches apart and allowing air
to get under the fuel. Criss-crossing or arrang-
ing the fuel so that air can get underneath, will
help the fire to get started easily. The unit should
be operated with the air control fully open long
enough to get the cord wood well ignited.
Use caution when firing with the combustion
air control wide open. Only burn cord wood in
this manner. Small dry pieces of softwood and
constructionscrapswillburnveryintenselyus-
ing this method and may damage the firebox.
Medium Combustion
COMBUSTION CONTROLS
This is the recommended mode of operating
the Montecito fireplace and should be the one
normally used since it will deposit the least
amount of creosote on the glass and in the
chimney. The combustion air control must be
3/4 closed and pushed in to close the air boost.
The precise setting will depend on many fac-
tors,includingchimneylengthandthemoisture
content of the wood.

B. Fans operating (e.g.: range hood) - These
fans draw air out of the house and may
actually cause a negative pressure in the
house. Turn off all fans and open a nearby
window to determine if this is the cause of
the problem.
C. Wetwood-Wetortarredwoodwillsmoulder

dealer can help you determine if you have
properly seasoned wood for burning.
D. Dirty or blocked chimney - Check to make
sure the chimney is clear and clean. If dirty
call a certified chimney sweep or use a
properly sized chimney brush to clean.
E. Chimney not long enough - The minimum
chimney height is twelve (12) feet (3.7 m)
not including the fireplace height. The
chimney must extend at least three (3) feet
(915 mm) above its point of contact with
the roof and at least two (2) feet (610 mm)
higher than any roof or wall within ten (10)
feet(3m)ofit. Wheninstalledwithoffsets,

installed against an outside wall without
protectionmaygeneratebackdraftproblems
which will cause start-up problems. To
prevent this, open a nearby window, roll up
a piece of paper and light it. Then, hold it in
the upper part of the firebox to warm up the
chimney. Wait until the draft is sufficient,
then start the fire.

Dealing With a Chimney Fire
Regular chimney maintenance and inspection
canpreventchimneyfires. Ifyouhaveachimney
fire, follow these steps:
1. Closethefireplacedoorandthecombustion
air controls.
2. Alert your family of the possible danger.
3. If you require assistance, alert your fire
department.
4. If possible, use a dry chemical fire extin-
guisher, baking soda or sand to control the
fire. Do not use water as it may cause a
dangerous steam explosion.
5. Check outside to ensure that sparks and hot
embers coming out of the chimney are not
igniting the roof.
6. Do not use the fireplace again until your
chimney and fireplace have been inspected
by a qualified chimney sweep or a Fire
Department Inspector.
H. Do not burn wood in the area in front of the
grate.
I. Do not allow the wood to smoulder or burn
without flame, since this will produce
excessive creosote in the unit as well as
increased particulate emissions.
J. Blower for forced air kit operating - Make
surethattheblowerisatthe“off”positionwhen
you open the fireplace door for reloading.
MAINTAINING YOUR FIREPLACE
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 relatively
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.
Top Baffle Removal Prior to Cleaning The
Chimney
The chimney shall be inspected at least twice
a year during the heating season to determine
when a creosote buildup has occurred.
Before starting to clean your chimney, we
recommend that you remove the top baffle to
avoid creosote dust collection at the top of the
baffle. Follow these steps to set the top baffle
out of the way:
When creosote has accumulated it shall be
removed to reduce the risk of a chimney fire.
1. Remove the side refractory holder. They are
located at the top of the refractory.
When the creosote accumulation is large, a
creosote fire in the chimney can damage the
chimney and overheat the surrounding wood
framing. Creosote formation in a chimney can
be minimized by making sure there is always
visible flame burning, avoid smouldering fires
and by proper refuelling techniques.
2. Lift the front baffle.
3. Slide the back baffle under the front baffle.
You now have access to the chimney.
Chimney Maintenance
Regular chimney inspection and maintenance
combined with proper operation will prevent
chimneyfires.Keepyourchimneyclean. Donot
allow more than 1/16” (1.6 mm) creosote build
upinyourchimney. Theamountofcreosotewill
depend on variables such as frequency of use
and type of fire. We recommend that you:
A. Initially inspect the chimney system weekly.
From this, you will learn how often it will be
necessary to clean your chimney.
B. Have your chimney cleaned by a qualified
chimney sweep. If you wish to clean it
yourself, werecommendusingastiffplastic
or non-metallic brush. If a metal brush is
used, its size should be slightly smaller than
the flue to avoid damaging the chimney. Do
notuseabrushthatwillscratchthestainless
steel interior of the chimney.
IMPORTANT CAUTIONS
A. Do not block the hot air vents to the fire-
place as this will cause the fireplace to
overheat.
B. Never use gasoline, gasoline-type lantern
fuel, kerosene, charcoal lighter fluid, or
similar liquids to start or ‘freshen up’ a fire
inthisfireplace. Keepallsuchliquidswell
away from the fireplace while it is in use.
C. Do not burn coal. The sulphur in coal will
corrode the firebox and chimney.
Figure 2A - Top Baffle Removal
D. Keep combustible materials at least 48”
(1.2m)awayfromthefrontofthefireplace
opening.
E. Never leave children unattended when
there is a fire burning in the fireplace.
F. Do not use the fireplace as an incinerator
to burn paper, cardboard or construction
material such as pressed wood, plywood
or lumber. Use only untreated wood.
Wood protectors, metallic paper, coal,
plastic, waste, beach wood, Christmas
tree, sulphur and/or oil will damage the
fireplace.
C. Do not expect chemical cleaners to keep
your chimney clean. The rain cap can be
removed for inspection and/or cleaning of
the chimney.
Caution: It is necessary to remove the baffle
from the top of the firebox before cleaning the
chimney. See “Top Baffle Removal Prior To
Chimney Sweep.”

Finish Door Casing Care
Use a glass cleaner and a soft cloth to polish
the casing. Do not use abrasives such as steel
wool, steel pads or an abrasive polish for they
may scratch the casing’s finish.

DOOR INSTALLATION
The door must be installed only when the installation of the Montecito™ fireplace is completed.
All you have to do is fit the male part of the hinge, already on the door, to the female part, which
is on the fireplace. To remove the door, simply pull the door up from the hinges (see Figure 4).
The door adjustment has been set at the factory. If the fit is still not perfect, you can adjust the
door using the hinge screws.
DOOR ADJUSTMENT
The door may need to be adjusted to be completely airtight. The gaskets’ air-tightness can be
adjusted using the adjustment screw located on the right side of the fireplace facade (An Allen key
#1/8 – not supplied - will be necessary for this adjustment).
REFRACTORY REPLACEMENT
The intense heat of the fire will normally cause
hairline cracks in the refractory. These cracks
canbeminimizedbypropercuringasdescribed
in “First Fires”. They will not normally dimin-
ish the effectiveness of the refractory. If large
cracks develop, then the refractory should be
replaced. To replace the refractory bricks, fol-
low these steps:
Checking Door Seal
A one-inch strip of paper may be used to perform a test of the integrity of the door seal. Close
the door on the paper in at least eight points. It is normal to feel only a slight amount of friction.
The door gasket does not need to be “tight” in all areas, since a small amount of leakage is not
hazardous or detrimental to the performance of your fireplace.
1. Remove the front refractories
WARNINGS
2. Remove the bottom refractory
3. Remove the left side refractory
• Use only a Lennox Hearth Products glass doors, specifically designed
4. Remove the right side refractory
5. Remove the back refractory

The heating performance of the appliance will
vary depending upon the level of insulation,
house design, how the appliance is operated,
etc.
Also, the outside air inlet duct should be wrapped with noncombustible insulation to minimize
the formation of condensation. Do not place insulation materials directly against the chimney
sections. We recommend that you use the insulated wall radiation shield since it will maintain the
home’s thermal barrier. AC chimney is NOT recommended in very cold climates (in areas with
temperatures below 0°F (-18°C).
If this fireplace is being installed in a cold
climate, it is especially important to seal all
cracks around the fireplace and wherever cold
air could enter the room with noncombustible
material.

Figure 17
Make a 4-1/4” (110 mm) hole in the outside
wall of the house at the chosen location. From
outside,placetheoutsideairregisterinthehole
(open side down) and fasten the register to the
wall with screws as shown (see Figure 18).
Slip the pipe into the insulated sleeve. Place
the insulated pipe over the register tube and
over the fireplace’s outside air connector (see
Figure 19). At each end, carefully pull back the
insulation and plastic cover exposing the flex-
ible pipe. Using the aluminium tape provided,
wrap the tape around the joint between the
flexible pipe and the air inlets. Carefully push
the insulation and plastic cover back over the
pipe. Using aluminium tape, fasten the plastic
cover in place.
5. Whentraversingacombustiblewallorfloor,
a firestop must be installed at the wall or
floor penetration. The hole size must be
13” x 13” (330 mm x 330 mm)
6. Do not connect the hot air ducts to a central
heating system. Malfunction of the heating
system’s blower will cause the fireplace to
overheat. A furnace duct is only single wall
and not double wall as is required for the
Montecito fireplace hot air exhaust.
7. Use only Lennox Hearth Products grills and
components as described in this manual.
Other grills or registers, for example, may
be too restrictive and may overheat the
fireplace or ceiling.
8. Do not use insulated flexible ducts as they
will overheat.
9. Do not use tees or any other components
than the ones specifically listed here.
10.Never allow the ducting to pitch down as
hot air will be trapped creating a fire hazard.
Never route the ducting downwards.
11.Thehotairoutletgrillsmustbeinstalledwith
the louvers pointing downwards in order to
prevent overheating adjacent ceilings.
12.Always install the two outlet grills when
using the double hot air outlet kit.
The duct system must be installed respecting
the following:
1. Removetheplatesclosingupthe8”dia.holes
on top of the fireplace. Then, cut the insula-
tion in order to obtain two 8” dia. openings.
Fix the adaptors on the fireplace openings
by turning clockwise (Figure 15).
2. Maintain at least a 2” (50 mm) clearance
between the ducts and any combustible
material; the required hole size is 13” x 13”
(330 mm x 330 mm).
Exception #1: For the grills, the fram-
ing can be 10-3/4” x 10-3/4” (275 mm
x 275 mm) to provide the clearance as
required by the integral spacers on the
double outlet duct system.
NOTE: We recommend not to exceed twenty
(20) feet of 4” flexible pipe. If you require a
longer length we recommend that you use a 5”
diameter flexible pipe for the complete run up
to thirty (30) feet and a 6” diameter pipe for a
run of up to forty (40) feet.
3. The maximum number of elbows in a run
of duct is two.
4. Maintainatleast6-1/2”(160mm)clearance

5. All chimney installations must include at least one support. Re-
ducing the amount of chimney weight on the fireplace will help avoid
the noise created when the fireplace expands. This can be achieved
by having the chimney supported by the supports. The maximum
chimney length that can be supported by the fireplace is nine (9) feet
(2.75 m) for S-2100+/HT6000+, twelve (12) feet (3.7 m) for ASHT+
/ HT6103+ and 26 feet (8 m) for AC chimney.

of contact with the roof and at least two (2) feet (610 mm) higher than
any wall, roof or building within ten (10) feet (3m) of it (Figure 20).
7. Ifthechimneyextendshigherthanfive(5)feet(1,500mm)aboveitspoint

8. A rain cap must be installed on top of the chimney. Failure to install
a rain cap may cause corrosion problems.
9. Cut and frame square holes in all floors, ceilings, and roof that the
chimney will go through to provide a 2” (50 mm) clearance between
the chimney and any combustible materials. Do not fill this 2” space
with insulation or any other combustible material.

THE CHIMNEY SYSTEM
Chimney Installation Notes
1. If possible, install an interior chimney as it will provide better perfor-
mance. In areas with continuous temperatures below -18° C (0° F),
the use of an exterior chimney increases the likelihood of operating
problems such as low draft, high rate of creosoting, and poor start-up
characteristics. Exteriorchimneysarealsopronetodown-withdryand
flow reversal. Installations, which are located on lower floors in the
house, such as in a basement, in combination with outside chimney,
are especially prone to flow reversal.
2. The Lennox Hearth Products fireplace model MONTE may be installed
only with Security Chimneys International 6” diameter chimney sys-
tems.
3. A chimney venting a fireplace shall not vent any other appliance.
4. The minimum chimney height is twelve (12) feet (3.7 m). In altitude,
add 18” (450 mm) to the chimney for every 2,000 feet (600 m) above
sea level.

ANGLED WALL RADIATION SHIELD
(RSM+ and RSMI30)
OFFSET CHIMNEY INSTALLATION
Chimney AC
When traversing a combustible wall with the chimney at a 30º or 45º
angle, an angled firestop or wall radiation shield must be installed. Only
one is required.
Note: 45º angle for Canada only (RSMI45)
Support
ACRS
In cold climate locations (climates where temperatures will fall below 32°
F / 0° C), we recommend that you use the insulated wall radiation shield
since it will maintain the home’s thermal barrier.

Gasket Replacement
GLASS CARE
Remove the door from the unit (see Page 6)
and lay it on a clean unabrasive surface. To
replace the gasket, first remove all of the old
gasket and gasket cement. Make sure that the
surface is totally clean before applying new
cement (a high temperature silicone caulking
ratedat500°F[260°C],issuitable)oradhesion
problems may result. Apply gasket cement to
the gasket channel and install the new gasket.
This replacement part is available from your
Lennox Hearth Products dealer in the following
dimensions:
Glass Replacement
The glass used for the Montecito™ fireplace is
a high temperature ceramic glass (1,400° F /
760°C). Iftheglassbreaks, itmustbereplaced
with an identical ceramic glass. Tempered
glass or ordinary glass will not withstand the
high temperatures of the Montecito fireplace.
Replacementglassshouldbepurchasedfroma
Lennox Hearth Products dealer (see “Replace-
ment Parts”, Page 23). DO NOT OPERATE THE
UNIT WITH CRACKED OR BROKEN GLASS.
Usually, no additional floor support is needed
for the fireplace. The adequacy of the floor
can be checked by first estimating the weight
of the fireplace system. Weights are given
on Page 23. Note the floor construction and
consult your local building code to determine
if additional support is needed.
The Montecito fireplace may be installed
directly on the floor or on a raised base (for
proper guidelines, refer to “Hearth Extension
Requirements”) and a minimum of 6’8” (2 m)
measured from the base of the appliance to the
ceiling is required.
Glass Cleaning
Gasket Length Dimensions
Steel Door
Part No.
The Montecito fireplace is designed to keep
the glass clean under normal operating condi-
tions. If the Montecito fireplace is operated
continuously with the combustion air controls
closed, the glass will tend to get dirty unless
the fuel, firebox and glass are maintained at
hot temperatures (see “Refueling For Best
Performance”). To clean the glass, there are a
number of specially designed cleaners. Your
authorized Lennox Hearth Products dealer can
recommendasuitablecleanerwhichisavailable
in your area. Regular household glass cleaners
will not clean creosote. Do not use abrasives
such as steel pads, steel wool or oven cleaner
as they will scratch the glass.

Locating The Montecito Fireplace
The best location to install your fireplace is
determined by considering the location of
windows,doors,andthetrafficflowintheroom
where the fireplace is located, allowing space
in front of the unit for the hearth extension and
the mantel, and taking into consideration the
location of the hot air ducts (optional), outside
air kit and chimney.

This support has three possible uses:
1. For ASHT+ / HT6103+ and S-2100+ / HT6000+, it must be used on a
roof to support the chimney.
2. It may be used on a floor, ceiling or roof above an offset to support
the chimney above the offset.
3. It may be used on a floor, ceiling or roof as a supplementary sup-
port.
18” (460 mm)
Table 6 gives maximum height of supported chimney.
NOTE: For the AC chimney, a support section must be used every forty
(40) feet (12 m) instead of the universal roof support (ST).
For roof support installation, refer to the instructions provided with the
support.

CHIMNEY ADAPTOR (S-2100+ / HT6000+) CANADA ONLY
This support is used to support the chimney above an offset. When
the chimney offset is used to traverse a wall this support may be used
on the wall to support the chimney. The maximum heights are given in
Table 6. For offset support installation, refer to the instructions provided
with the support.
The fireplace is normally supplied with a chimney adaptor suitable for the
ASHT+ / HT6103+ chimney. If you want to install a S-2100+ / HT6000+
chimney, an adaptor is available (6UCA) (Figure 31). A separate starter
section will also be required if AC chimney is installed.

CHIMNEY CHASE AND MULTIPLE TERMINATIONS
For the purpose of this manual, a chimney chase is considered a part of
the chimney system rather than part of a building. The termination must
be placed a minimum of 18” (460 mm) above the chase.
For installations where more than one chimney is located in the same
chase or within the same area, we suggest that their terminations be
separated by at least 16” (410 mm) horizontally, and 18” (460 mm) verti-
cally. This separation is to prevent smoke migrating from one chimney
to another (see Figure 30).

Follow these steps:
INSTALLATION INSTRUCTIONS FOR MASONRY APPLICATION
1- Position the fireplace in its location. Temporarily install the ASHT+
elbow on the top of the fireplace and, using a level, mark with an oval
the location where the flue liner will enter the masonry chimney.
2- In the middle of the oval, drill a hole in the masonry chimney at 30º.
3- Increase the size of the hole until a 30º TUBINOX liner elbow can be
easily slipped through.
WARNING: Before starting the installation, the masonry chimney
must be inspected by a qualified chimney sweep.
The following requirements must be respected:
1. The chimney must be absolutely clear of any soot residue or creosote.
Check for cracks, loose or missing bricks that could inhibit correct
installation of the liner.
4- Slide the liner down from the top of the masonry chimney until you
reach the hole level.
2. The clearance to combustible must be a minimum of 1” between the
outside of the masonry and any wood framing or loose insulation.
3. The chimney must be built in accordance with the current building
code.
4. No other appliance can be connected to the same chimney.
5. The clearances to combustible for these fireplace connectors are 2”
on the side and bottom and 16” at the top.
5- Slip through the hole a 30º liner elbow and connect it to the liner.
6- Add a small liner section to the liner elbow which will allow the liner to
extend at least 12” (measured at the top of the liner) from the masonry
chimney.
7- Seal the opening around the liner with high temperature refractory
cement.
8- The next steps must be done in the following order:
6. The connector parts are not necessary if the connection between the
insulatedlengthandthestainlesssteellinerisdonewithinthemasonry
chimney.
See typical installation illustrated below.
A. Select the ASHT+ length that will fit between the elbow and the liner
so that it will slide at least 2” over the liner section (You may need to
cut the liner for a better fit).
B. Take that section and the BISUMA30 cover and slide it over the liner.
Make sure you have enough opening to be able to install the ASHT+
elbow without difficulty.
C. Install the 30º elbow on the fireplace.
D. Slide the length section back down on the elbow and twist lock the
two together.
E. Pull the cover down over the length and install the insulation pad over
the liner; be careful to cover the liner completely.
F. Slide back the cover over the insulation and fix it in place using the 3
metal screws supplied.
Installation:
The chimney must be relined with a stainless steel liner model TUBINOX
or Projet SS of the same diameter as the outlet of the fireplace.
For connection at a 30º angle, a special connector (BISUMA30) must be
used to connect the liner to the insulated chimney.
* IMPORTANT NOTE - The use of a 45º connector (BISUMA) is ap-
proved for use in Canada ONLY. Installations in the USA must use the
30º connector (BISUMA30).
