CONGRATULATIONS!  
In selecting this Lennox Hearth Products wood-burning appliance you have chosen  
one of the finest fireplaces available. The Brentwood™ fireplace is a clean burning EPA  
certified fireplace that is designed to provide you dependable service as well as warmth  
and enjoyment for many years to come.  
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

will be useful to you now and in years to come, so keep the manual handy and refer to  
it as needed.  
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.

First Fires  
Before using the fireplace make sure to re-  
move 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.

Building a Fire  
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  
Accelerated  
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.  
Figure 1  
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 ar-  
ranging 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.  
COMBUSTION CONTROLS  
Medium Combustion  
Primary Air and Air Boost Controls  
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  
manyfactors,includingchimneylengthandthe  
moisture content of the wood.  
Onceyouhavereachedthedesiredtemperature,  
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  
techniquewillbecleanerglass,lesscreosoting,  
greater efficiency and the most pleasing fire for  
your enjoyment.  
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  
controlislocatedbelowthedoorontheleftside.  
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  
combustionaircontrolshouldbeopenedbefore  
opening the door to minimize the possibility of  
back draft coming into the room.  
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  
hotcoals.Theheatoutputwillbeapproximately  
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.  
SMOKING –  
CAUSES AND TROUBLESHOOTING  
Toreducethelikelihoodofsmokingwhenopen-  
ing the door, set the combustion air controls to  
the left before opening the door. Your fireplace  
hasbeendesignedandtestedtoprovidesmoke  
free operation. Occasionally, there may be a  
smallamountofsmokinguponlightingthere,  
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:  
Slow Combustion  
When the air combustion control is completely  
closed, the fireplace is in a slow combustion  
phase.Ifthehearthishotenough,slowcombus-  
tion 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,sincethiswillproduceexcessivecreosote  
in the unit.  
A. Negative pressure in the house  
As the fire burns, air goes up the chimney.  
This air must be replaced through leakage  
intothehouseorthroughtheoutsideairduct.  
When operating the Brentwood fireplace,  
openanearbywindowtemporarilytocheckif  
there is adequate replacement air supply.  
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.

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.

D. Dirty or blocked chimney  
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.

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

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.  
IMPORTANT CAUTIONS  
A. Do not block the hot air vents to the fire-  
place as this will cause the fireplace to  
overheat.  
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.  
Finish Door Casing Care  
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. Donotburndriftwoodwhichhasbeeninthe  
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  
cardboardorconstructionmaterialsuchas  
pressed wood, plywood or lumber. Wood  
protectors, metallic paper, coal, plastic,  
waste, sulphur and/or oil will damage the  
fireplace.  
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.  
Top Baffle Removal Prior to Cleaning The  
Chimney  
DISPOSING OF ASHES  
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:  
Remove ashes only when the fire is out and  
the ashes are cold (24 to 48 hours after the  
fire is out).  
1. Remove the side refractory holder. They are  
located at the top of the refractory.  
WARNING  
2. Lift the front baffle.  
3. Slide the back baffle under the front baffle.  
You now have access to the chimney.  
Disposal of Ashes: Ashes should  
beplacedinametalcontainerwith  
a tight fitting lid. The closed con-  
tainer 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  
otherwiselocallydispersed, they  
should be retained in the closed  
container until all cinders have  
thoroughly cooled.  
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.

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-

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).  
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 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.  
Replacementglassshouldbepurchasedfroma  
Lennox Hearth Products dealer (see “Replace-  
ment Parts”, Page 23). DO NOT OPERATE THE  
UNIT WITH CRACKED OR BROKEN GLASS.  
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).  
Notetheoorconstructionandconsultyour  
localbuildingcodetodetermineifadditional  
support is needed.  
C. The Brentwood fireplace may be installed  
directly on the floor or on a raised base (for  
properguidelines,refertoHearthExtension  
Requirements”) and a minimum of 6’8” (2  
m) measured from the base of the appliance  
to the ceiling is required.  
Glass Cleaning  
The Brentwood fireplace is designed to keep  
the glass clean under normal operating condi-  
tions. 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  
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.

Figure 7b - Hearth Extension Requirements  
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.

necessary to purchase two adjustable lengths  
(7B26ZL2A).  
See Gravity Kit Accessories on Page 21.  
When installing the double outlet system, the  
hotairoutletscanbeinstalledinthesameroom

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).  
Theonlyblowerthatcanbeusedwiththegravity

The duct system must be installed respecting  
the following:  
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 blow-  
ers 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.  
1. Removetheplatesclosingupthe8dia.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 12).  
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.  
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).  
Outside Air Installation  
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.  
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.  
3. The maximum number of elbows in a run  
of duct is two.  
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.  
4. Maintainatleast6-1/2(160mm)clearance  
fromtheoutletgrillframingtoacombustible  
ceiling, side wall or mantel.  
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.  
5. Whentraversingacombustiblewalloroor,  
a firestop must be installed at the wall or  
floor penetration. The hole size must be  
13” X 13” (330 mm x 330 mm).  
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)  
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.  
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.  
7. Use only Lennox Hearth Products grills and  
components as described in this manual.

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.  
8. Do not use insulated flexible ducts as they  
will overheat.

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.  
Support

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.

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 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  
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 28). 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 27).

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.  
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.  
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:  
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.  
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).
