OPERATING THE BRENTWOOD FIREPLACE
Fuel
USE SOLID NATURAL WOOD FUEL ONLY. The
Brentwood fireplace is designed to work best
when fueled with dry seasoned natural wood
only. Hardwoods are preferred to softwoods
since the energy content of wood is relative to
its density. Hardwoods will result in a longer
burning fire and less frequent refueling. 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.
Excessively wet wood will be difficult to burn
and will result in lower efficiency, increased
creosoting and deposits on the glass and in
the chimney. Excessively dry wood will burn
well but will also have higher emissions and
shorter burning time.
Do not burn scrap or garbage, treated wood or
wood such as driftwood from the ocean which
has been exposed to salt or other chemicals.
Salt or chemicals can corrode the firebox and
chimney. Do not burn large amounts of paper,
cardboard, Christmas tree branches or building construction materials. Intense firing with
these materials may overheat the fireplace,
causing damage to the unit, a fire or even
possibly igniting a chimney fire if the chimney
is creosoted.
First Fires
Before using the fireplace make sure to remove the plastic wrapping and EPA label on
the door. Remove any glue residue left by the
label using mild soap.
The first five or six fires should be small fires of
short duration (about 30 to 60 minutes). This
will help cure the refractory bricks. The first
fires may produce slight smoking and some
odor due to curing of the paint and steel and
the burning off of dust accumulated on the
fireplace will burn off at this time. It may set off
a smoke alarm located in the same room. For
this reason the room should be well ventilated
for the first few fires.
WARNING
Be careful adding wood fuel to the
fire or handling fireplace tools such
as shovels, tongs or pokers.
WARNING
The bottom refractory can be
cracked by excessive abuse such
as tossing heavy logs onto the
grate or gouging with fireplace
tools. Exercise caution when
adding wood to your fireplace.

Building a Fire
(starting and maintaining a fire)
To start a fire, place several crumpled up balls of
newspaper in the firebox. Place small dry pieces
of kindling on top of the paper, criss-crossing
the 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).
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 arranging 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.
COMBUSTION CONTROLS
Primary Air and Air Boost Controls
There is no flue damper in the Brentwood™
fireplace. As is common with air tight stoves,
the combustion air control sets the flow of air
entering the firebox. This allows for a more
precise control of the fire. The combustion air
control is located below the door on 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. Pulling the air combustion control
will induce an air boost at the base of the fire
allowing an easier fire start up. When the fire is
well established, 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.
Accelerated Combustion
The maximum heat output for the Brentwood™
fireplace is achieved by burning with the door
closed and the combustion air opened and
pulled out. By this method, the Brentwood
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
Brentwood fireplace.

Figure 1
Use caution when firing with the combustion
air control wide open. Only burn cord wood in
this manner. Small dry pieces of softwood and
construction scraps will burn very intensely using this method and may damage the firebox.
Medium Combustion
This is the recommended mode of operating
the Brentwood 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 factors, including chimney length and the
moisture content of the wood.
For instance, a long chimney will necessitate
closing the damper more. To obtain the proper
combustion, close the damper completely, then
open it about 1/4” to 1/2”. Three medium size
pieces of wood should be burning on a bed of
hot coals. The heat output will be approximately
30,000 BTU per hour and the loading time will
be about every 3-4 hours. Softwoods may be
burned using this method but the time will be
substantially reduced.
Slow Combustion
When the air combustion control is completely
closed, the fireplace is in a slow combustion
phase. If the hearth is hot enough, slow combustion will not extinguish the fire, but there will be
a noticeable 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.
Creosote may accumulate on the glass door.
This method of burning should be used only
after operating the Brentwood 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.
REFUELING FOR BEST PERFORMANCE
The Brentwood fireplace will operate best if
attention 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.
Once you have reached the desired temperature,
the air boost can be closed and the primary air
set to a medium setting. You know you have
reached the desired temperature when, closing
the primary air control, you can see a flame
at the top of the firebox. The benefit of this
technique will be cleaner glass, less creosoting,
greater efficiency and the most pleasing fire for
your enjoyment.
SMOKING –
CAUSES AND TROUBLESHOOTING
To reduce the likelihood of smoking when opening the door, set the combustion air controls to
the left before opening the door. Your fireplace
has been designed and tested to provide smoke
free operation. Occasionally, there may be a
small amount of smoking upon lighting the fire,
until the chimney heats up but this should not
continue. If the fireplace continues to smoke it
is probably for one of the following reasons:
A. Negative pressure in the house
As the fire burns, air goes up the chimney.
This air must be replaced through leakage
into the house or through the outside air duct.
When operating the Brentwood fireplace,
open a nearby window temporarily to check if
there is adequate replacement air supply.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
B. Blowers operating (e.g.: range hood)
These blowers draw air out of the house and
may actually cause a negative pressure in
the house. Turn off all blowers and open a
nearby window to determine if this is the
cause of the problem.
C. Wet wood
Wet or tarred wood will smoulder and smoke
instead of burn properly.
D. Dirty or blocked chimney
Check to make sure the chimney is clear and
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 (3 m) of it. When installed with offsets,
the minimum chimney height is fifteen (15)
feet. Additional height will increase draft and
will decrease the tendency to smoke.
F. Poor chimney draft
With no fire, there should be sufficient draft to
exhaust cigarette smoke introduced under the
baffle. Chimneys installed against an outside
wall without protection may generate back draft
problems 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.
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
in this fireplace. Keep all such liquids well
away from the fireplace while it is in use.
C. Do not burn coal. The sulphur in coal will
corrode the firebox.
D. Do not burn driftwood which has been in the
ocean or salt water. The salt will corrode
the firebox and chimney.
E. Do not burn wood in the area in front of the
grate.
F. Do not abuse the unit by burning paper, or
cardboard or construction material such as
pressed wood, plywood or lumber. Wood
protectors, metallic paper, coal, plastic,
waste, sulphur and/or oil will damage the
fireplace.
G. Do not allow the wood to smoulder or burn
without flame, since this will produce
excessive creosote in the unit.
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.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
As a result, creosote residue accumulates on the
flue lining. When ignited this creosote makes
and extremely hot fire.
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.
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.
Chimney Maintenance
Regular chimney inspection and maintenance
combined with proper operation will prevent
chimney fires. Keep your chimney clean. Do not
allow more than 1/16” (1.6 mm) creosote build
up in your chimney. The amount of creosote will
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, we recommend using a stiff plastic
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
not use a brush that will scratch the stainless
steel interior of the chimney.
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.
Top Baffle Removal Prior to Cleaning The
Chimney
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:
1. Remove the side refractory holder. They are
located at the top of the refractory.
2. Lift the front baffle.
3. Slide the back baffle under the front baffle.
You now have access to the chimney.
Figure 2a - Top Baffle Removal
Figure 2b - Top Baffle Removal
Dealing With a Chimney Fire
Regular chimney maintenance and inspection
can prevent chimney fires. If you have a chimney
fire, follow these steps:
1. Close the fireplace door and the combustion
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.
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.
DISPOSING OF ASHES
Remove ashes only when the fire is out and
the ashes are cold (24 to 48 hours after the
fire is out).
WARNING
Disposal of Ashes: Ashes should
be placed in a metal container with
a tight fitting lid. The closed container of ashes should be placed
on a non-combustible 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.
-

REFRACTORY REPLACEMENT
The intense heat of the fire will normally cause
hairline cracks in the refractory. These cracks
can be minimized by proper curing as described
in “First Fires”. They will not normally diminish the effectiveness of the refractory. If large
cracks develop, then the refractory should be
replaced. To replace the refractory bricks, follow these steps:
1. Remove the front refractories
2. Remove the bottom refractory
3. Remove the left side refractory
4. Remove the right side refractory
5. Remove the back refractory
6. Remove the front ceramic baffle
7. Remove the rear ceramic baffle
To install the new refractories, follow the above
steps in reverse.
DOOR INSTALLATION
The door must be installed only when the installation of the Brentwood™ 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.
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).
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.

GLASS CARE
Glass Replacement
The glass used for the Brentwood™ fireplace
is a high temperature ceramic glass (1,400°
F). If the glass breaks, it must be replaced
with an identical ceramic glass. Tempered
glass or ordinary glass will not withstand the
high temperatures of the Brentwood fireplace.
Replacement glass should be purchased from a
Lennox Hearth Products dealer (see “Replacement Parts”, Page 23). DO NOT OPERATE THE
UNIT WITH CRACKED OR BROKEN GLASS.
Glass Cleaning
The Brentwood fireplace is designed to keep
the glass clean under normal operating conditions. If the Brentwood 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
recommend a suitable cleaner which is available
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.
DO NOT USE CHEMICAL GLASS CLEANERS
ON PAINTED SURFACES AS IT MAY CAUSE
THE PAINT TO PEEL.
CAUTION : DO NOT ALLOW WINDOW CLEANER
TO GET IN CONTACT WITH DOOR GASKET OR
PAINT ON FACADE OR DOOR. ONCE CLOSED,
CONTACT OF GLASS CLEANER WITH THE
FIREPLACE FACADE CAN PROVOKE PAINT
PEELING OFF.
Gasket Replacement
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
rated at 500° F [260° C] is suitable) or adhesion
problems may result. Apply gasket cement to
the gasket channel and install the new gasket.

FIREPLACE INSTALLATION
Locating The Brentwood Fireplace
A. The best location to install your fireplace is
determined by considering the location of
windows, doors, and the traffic flow in the
room 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.
If possible, you should choose a location
where the chimney will pass through the
house without cutting floor or roof joists
(see fireplace dimensions Page 9).
B. 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 in the appendix. Next, measure
the area occupied by the fireplace which is
normally 36” x 24-1/2” (914mm x 622mm).
Note the floor construction and consult your
local building code to determine if additional
support is needed.
C. The Brentwood 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.
When selecting the location, the chimney outlet
position and the direction of the wind are important factor affecting the chimney performance.
To allow a maximum draft and to reduce wind
turbulence, the chimney must:
• Penetrate the highest part of the roof.
• Be installed as far as possible of roof offsets,
trees or any other obstructions that may

Framing, Facing And Mantel
The construction of the framing, facing, and
mantel must be in accordance with the standards and the following illustrations (Figures
7a, 7b and 8):
A. Frame the fireplace using 2” x 3” or heavier
lumber.
B. WARNING: Combustible materials
cannot be used in the space directly
above the fireplace, except for the
studs above the facade that support
the facing and mantel. This area must
remain empty for a height of 6’8”
(2,032 mm) measured from the base
of the appliance.
C. Frame the fireplace with vertical studs at the
sides of the fireplace running from floor to
ceiling (see Figure 8). If combustible facing
is to be used, position the studs back, from
the front edge of the fireplace (a space that
is the thickness of the facing material, so
that the facing can be installed flush with the
fireplace facing). Frame headers between
the vertical studs only as follows:
- Place 2” x 3” or 2” x 4” headers,
only along the upper part of the front,
side and back faces (some codes
may require a 2” x 6 ” on an outside
bearing wall). Do not put wood or any
combustible material within the area
above the fireplace except on the front
facing.
- Place headers only as required to support
the facing and mantel.
D. WARNING: The fireplace must not be
in contact with any insulation or loose
filling material. Cover the insulation with Drywall panels around the
fireplace.
Fireplace
The crack between the fireplace
and the hearth extension must be
sealed with a non-combustible
material such as sand-cement
grout.

HOT AIR DUCTING INSTALLATION
The Brentwood™ fireplace is approved for use
with a Gravity Kit.
Grill
Frame
For safe installation, the gravity kit must meet
the following requirements:
Minimum height* 68” (1,727 mm)
Maximum length See
Figures 13 and 14
Gravity Kit
The gravity kit is designed for double hot air outlets and includes: (See Figures 12 and 13)
- 2 telescopic lengths 8” I.D.
- 2 90º elbows 8” I.D.
- 2 hot air outlet kits (grill and frames)
- 2 adaptors
See Gravity Kit Accessories on Page 21.
The only blower that can be used with the gravity
kit is the UZY5.
The gravity kit allows you to block the upper
louver of the fireplace. To do so, follow the
steps below:
a) Remove the upper louver from the fire-
place.
b) Install the black panel (BWCF) making sure
that the insulation strip is installed inside.
c) The fireplace facade can be covered with
non-combustible material (Figure 14).
WARNING: Both pipes of
the double hot air outlet
must be installed. Any other installation may cause
fire and void warranty.
Figure 12
* The height of the louver must be measured
from the base of the Brentwood fireplace to the
middle point of the louver.
To extend the double outlet system forward of
the Brentwood fireplace (not flush), it will be
necessary to purchase two adjustable lengths
(7B26ZL2A).
When installing the double outlet system, the
hot air outlets can be installed in the same room
as the fireplace, or one or both of the outlets
can be installed in adjacent or upper rooms.
Installing the ducts at different elevations will
tend to exhaust more heat out of the higher
outlet (Figure 13).

The duct system must be installed respecting
the following:
1. Remove the plates closing up the 8” dia. holes
on top of the fireplace. Then, cut the insulation in order to obtain two 8” dia. openings.
Fix the adaptors on the fireplace openings
by turning clockwise (Figure 12).
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.
3. The maximum number of elbows in a run
of duct is two.
4. Maintain at least 6-1/2” (160 mm) clearance
from the outlet grill framing to a combustible
ceiling, side wall or mantel.
5. When traversing a combustible wall or floor,
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
Brentwood™ 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. The hot air outlet grills must be installed with
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 and blocking the
upper louver of the fireplace.
OUTSIDE AIR KIT
During operation, the fireplace requires fresh air for combustion and draws air out of the house.
It may starve other fuel burning appliances such as gas or oil furnaces. As well, exhaust blowers may compete for air, causing negative pressure in the house, resulting in smoke entering the
house from the fireplace. This situation is aggravated in modern airtight houses. To overcome
this problem, we strongly recommend that you install an outside air assembly. Check with local
authorities having jurisdiction in your area, it may be mandatory.
Note: Should you decide not to install the outside air assembly, proceed as follows:
- Remove the bottom grill. The air box is located on front left and is on a slant.
- Unscrew the four screws holding the inside air box covering plate and remove it.
Outside Air Installation
The outside air assembly may be installed according to the following requirements:
A) Duct length should be kept to a minimum. The maximum length of duct is twenty (20) feet (6.1
m) for a 4 in. dia. pipe (See note below).
B) The air intake register must not be installed more than ten (10) feet (3050 mm) above the base
of the fireplace.
C) The fresh air must come from outside the house. The air intake must not draw air from the
attic, from the basement or garage.
D) The air intake should be installed where it is not likely to be blocked by snow or exposed to
extreme wind and away from automobile exhaust fumes, gas meters and other vents.
E) The duct and register may be installed above or below floor level.
The following components are required:
- Outside air kit (UZI) (includes 40 inch flex that goes up to ten (10) feet long)
- 4” Adaptor for fireplace connection (supplied with the unit)
Make a 4-1/4” (110 mm) hole in the outside wall of the house at the chosen location. From outside,
place the outside air register in the hole (open side down) and fasten the register to the wall, with
screws as shown (see Figure 15). 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 16). At each end,
carefully pull back the insulation and plastic cover exposing the flexible 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.
Note: We recommend not to exceed 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 30 feet and a 6”
diameter pipe for a run of up to 40 feet.

THE CHIMNEY SYSTEM
Chimney Installation Notes
1. Always install an interior chimney as it will provide better performance.
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.
Exterior chimneys are also prone to down drafting and 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. If interior installation is impossible, install an
AC chimney enclosed in an insulated chase.
2. The fireplace model Brentwood SP may be installed only with Security
Chimneys International Ltd 6” diameter chimney systems.
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.
10. Portions of the chimney which may extend through accessible spaces
must be enclosed to avoid contact with combustible materials or
damage to the chimney.
11.When offsets are used, the pipe may not penetrate a ceiling or floor
unless it is running vertical (no 30° offsets).
two (2) feet Min.
ten (10) feet
three (3) feet Min.
3. A chimney venting a fireplace shall not vent any other appliance.
4. The minimum chimney height is 12 feet (3.7 m). In altitude, add 18”
(450 mm) to the chimney for every 2,000 feet (600 m) above sea
level.
All chimney installations must include at least one support. The
5.
maximum length of chimney that can be supported by the fireplace
is 26 feet (8 m).

radiation shield from above (Figures 19a
through 19d).
3. For ASHT / HT6103+ AND S2100+ / HT6000+
chimneys place the first chimney length on
the fireplace. To lock it in place, turn 1/4
of a turn clockwise. With the AC chimney,
you must use a starter section (AC6SB or
AC6SB30) before installing the first chimney length (Figure 20). Continue installing
chimney lengths making sure to lock each
length in place.
4. Every time the chimney passes through
a ceiling or a wall, install the appropriate
firestop. When you reach the desired height,
install the roof support (Refer to instructions
included with the support).
5. Then, put the roof flashing in place and seal
the joint between the roof and the flashing
with roofing pitch (see Figures 21 and 22).
For sloping roofs, place the flashing under
the upper shingles and on top of the lower
shingles. Nail the flashing to the roof, using
roofing nails.
6. Place the spacers and the storm collar over
the flashing, and tighten it with the bolt
supplied. Finally, seal the joint between the
storm collar and the chimney, using silicone
caulking.
7. Install the chimney cap.

ANGLED WALL RADIATION SHIELD
(RSM+ and RSMI30)
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)
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.

CHIMNEY SUPPORT INSTALLATION
Universal Roof Support
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 support.
Table 6 gives maximum height of supported chimney.
NOTE: For the AC chimney, a support section must be used every 40 feet
(12 m) instead of the universal roof support (ST).
For roof support installation, refer to the instructions provided with the
support.
Universal Offset Support
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.

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) vertically. This separation is to prevent smoke migrating from one chimney
to another (see Figure 27).

INSTALLATION INSTRUCTIONS FOR MASONRY APPLICATION
Follow these steps:
WARNING: Before starting the installation, the masonry chimney
must be inspected by a qualified 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.
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 the BISUMA30 connectors are 2”
on the side and bottom and 16” at the top.
6. The connector parts are not necessary if the connection between
the insulated length and the stainless steel liner is done within the
masonry chimney.
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).
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 or 30º TUBINOX liner elbow can
be easily slipped through.
4- Slide the liner down from the top of the masonry chimney until you
reach the hole level.
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:
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.
