Fuel - USE SOLID NATURAL WOOD FUEL  
ONLY. The Cambria fireplace is designed to  
work best when fueled with seasoned cordwood.  
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 refuelling. 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.  
The Cambria™ wood-burning fireplace is a  
mid-efficient, heat radiating fireplace. You will  
receive a lifetime of comfort and enjoyment  
from your fireplace provided it is installed,  
maintained and operated properly.  
Please read these instructions and retain  
this manual for future reference.

Before beginning the fireplace installation,  
consult the local authorities to obtain your  
buildingpermitandcheckyourlocalbuilding  
codes. Installthereplaceonlyasdescribed  
in these instructions and using only Lennox  
Hearth Products components.  
• These appliances are not approved for  
Manufactured Home installations.  
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 build-  
ing 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.  
• When planning a fireplace installation the  
following information must be determined  
before beginning.  
1. Where the fireplace is to be installed.  
2. The configuration of the chimney.  
3. Optionalcomponentsinstallation(fan,  
hot air ducting, etc).  
4. Electrical wiring.  
5. Framing and finish details.  
Processed firelogs can be used. Although, do  
not poke or stir the logs while they are burning.

The Cambria fireplace includes a combustion  
air control that sets the flow of air entering  
the firebox and control the fire. The fireplace  
also includes a chimney damper that is not  
a combustion control. The chimney damper  
must always be in fully open position when  
the fireplace is used and should be closed only  
when all ashes are cold.

The maximum heat output for the Cambria  
fireplace is achieved by burning with the door  
closed and the combustion air opened. How-  
ever, it will be necessary to reload with wood  
every hour. This is the least efficient method  
of burning the Cambria fireplace. Use caution

operation. This will minimize air infiltration.  
The combustion air control should be opened  
before opening the doors to minimize the  
possibility of back draft coming into the  
room (see Figure 1-A). Also see Smoking

Building a Fire  
SMOKING –  
GAS LOG INSTALLATION  
CAUSES AND TROUBLESHOOTING  
A) To start a fire, place several crumpled up  
ballsofnewspaperintherebox. Placesmall  
dry pieces of kindling on top of the paper,  
criss-crossing the kindling so that there are  
air spaces in between. The kindling should  
be placed at the center of the firebox so as  
to allow for sufficient air circulation.  
B) Open the dampers and light the newspaper.  
Leave the doors partially opened (1 to 2  
inches) to facilitate the start-up.  
C) Once kindling fire is well established, cord-  
wood can be added. Close the doors and  
leave the combustion air control open in  
accelerated combustion position.  
D) When the fire burns well set the primary  
control to the desired burn level.  
Thisreplaceisdesignedtoallowtheinstallation  
of a gas burner. In such a case, the installation  
mustconformwiththeNationalGasCodeANSI  
Z223.1 and Z21.60. Warning: When using a  
gasburner,itismandatorytokeepthechimney  
outside air register opened.  
To reduce the likelihood of smoke coming  
into the room when opening the door, set the  
combustion air controls to the left (“Acceler-  
ated Combustion”) 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. If  
the fireplace continues to smoke it is probably  
for one of the following reasons:  
This fireplace has provision for the installation  
ofagaspipeandisintendedonlyforconnection  
to a decorative gas appliance incorporating an  
automatic shutoff device and complying with  
ANSI Z21.60-M96/CGA 2.26-M96, Standard  
for Decorative Gas Appliances for Installation  
in Solid-Fuel Burning Fireplaces (reference  
Clause 4.1.3 T).  
A. The doors are partially opened  
When you open the doors, open them com-  
pletely.  
B. Negative pressure in the house  
A fire needs air to burn. This air must be  
replaced through the outside air duct (see  
Outside Air on Page 16). When operating  
theCambriareplace,openanearbywindow  
temporarily to check if there is adequate  
replacement air supply.  
C. Fans operating (e.g.: range hood)  
Fans such as range hoods or bath fans draw  
airoutofthehouseandmayactuallycausea  
negative pressure in the house. Turn off all  
fansandopenanearbywindowtodetermine  
if this is the cause of the problem.  
D. Wet wood  
1. Remove the 1 inch knock-out on the right  
side of the fireplace and on the right side  
refractory.  
2. Drill a one inch hole in the hearth right side  
coaxial to the refractory opening.  
3. Assemble a rigid 3/8” N.P.T. iron pipe with  
two90ºelbows. Makesuretohave5-11/16”  
clearancebetweenthetwopipes(seeFigure  
4).  
4. Throughthehearthbottomorbackopenings  
insert the mounted pipe through the side  
of the firebox and the firebrick. Make sure  
the top elbow is as close as possible to the  
hearth to keep a minimum clearance to the  
retractable door.  
5. Insert a pipe through the 1 inch exterior  
knock-out and fix it to the 90º elbow already  
in place.  
The unit will burn best with 2-3 pieces of  
cordwood 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 cordwood well ignited.  
WARNING: The Cambria™ fireplace was de-  
signed to allow a spectacular view of the fire.  
The Cambria fireplace should never be filled  
in excess (five big logs or more). Excessive  
fire could damage the fireplace’s hearth and  
refractory brick and void the warranty.  
Wetortarredwoodwillsmoulderandsmoke  
instead of burning properly. Your dealer can  
help you determine if you have properly  
seasoned wood for burning.  
E. Dirty or blocked chimney  
REFUELING FOR BEST PERFORMANCE  
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.  
Note: In some regions, the use of a flexible gas  
pipe is allowed. Consult your local authority.  
To reload the Cambria fireplace:  
A) Completelyopenthecombustionair control  
(see Figure 2).  
F. Chimney not long enough  
The minimum chimney height is 15 feet (4.6  
m) not including the fireplace height. The  
chimney must extend at least 3 feet (915  
mm) above its point of contact with the roof  
and at least 2 feet (610 mm) higher than any  
roof or wall within 10 feet (3 m) of it. When  
installedwithoffsets,theminimumchimney  
height is 18 feet (5.5 m). Additional height  
will increase draft and will decrease the  
tendency to smoke.  
B) Open the doors about 1” and wait 5 seconds  
until the airflow has stabilized. Then open  
the doors completely, put the logs in and  
close the doors.  
C) Setthecombustionaircontroltothedesired  
burn level.  
Notes:  
G. Poor chimney draft  
• For spectacular fire and optimization of  
the fireplace efficiency, we recommend  
that the wood load be placed as far back  
as possible.  
• Itmaybenecessarytoturnoffanyblower(s)  
inoperationduringtherefuelingprocessin  
order to minimise smoking in the room. It  
is recommended to wait 15 to 30 minutes  
before turning the blower(s) back on to  
ensure successful rekindling.  
5-11/16”  
(145mm)  
With no fire, there should be sufficient draft  
toexhaustcigarettesmokeintroducedunder  
the baffle. Chimneys installed against an  
outside wall without protection may gener-  
ate back draft problems which will cause  
start-up problems. To prevent this, open  
a nearby window; roll up a piece of paper,  
light it and hold it in the upper part of the  
firebox to warm up the chimney. Wait until  
the draft is sufficient, then start the fire.  
H. Blower for central forced air kit  
Make sure that the blower is at the “off”  
position when you open the fireplace door  
for reloading.

A. Initially inspect the chimney system weekly.  
From this, you will learn how often it will be  
necessary to clean your chimney.  
IMPORTANT CAUTIONS  
Refractory Brick Replacement  
(refer to Figure 6)  
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 and chimney.  
D. Keep combustible materials at least 48”  
(1.2m)awayfromthefrontofthereplace  
opening.  
E. Never leave children unattended when  
there is a fire burning in the fireplace.  
F. Useonlyuntreatedwood. Woodprotectors,  
metallicpaper,coal,plastic,waste,sulphur  
and/or oil will damage the fireplace.  
G. Do not use the CAMBRIA as an incinerator  
to burn paper, cardboard or construction  
materialsuchaspressedwood,plywoodor  
lumber. Wood protectors, metallic paper,  
coal,plastic,waste,sulphurand/oroilwill  
damage the fireplace.  
B. Have your chimney cleaned by a qualified  
chimney sweep. If you wish to clean it your-  
self, we recommend using a stiff plastic or  
non-metallicbrush. Ifametalbrushisused,  
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.  
The intense heat of the fire will normally cause  
hairline cracks in the refractory brick. These  
cracks can be minimized by proper curing as  
described in First Fires on Page 4. They will  
not normally diminish the effectiveness of the  
refractory brick. If large cracks develop, then  
the refractory should be replaced. To replace  
the refractory bricks, follow these steps:  
Warning:Thechimneydampermustbeopened  
when sweeping the chimney to avoid ash and  
creosote accumulation in the fireplaces air  
circulation area.  
1. Remove the front refractory bricks  
2. Remove the andirons  
3. Remove the side refractory supports  
4. Remove the side refractory bricks  
5. Remove the back refractory brick  
6. Remove the bottom refractory brick  
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.  
To install the new refractory bricks, follow the  
above steps in reverse.  
Dealing With a Chimney Fire  
DOOR FRAME FINISH CARE  
Regular chimney maintenance and inspection  
canpreventchimneyres. Ifyouhaveachimney  
fire, follow these steps:  
1. IMPORTANT: Close the fireplace door and  
the combustion air controls; this will stifle  
the fire.  
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. 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, your dealer,  
or a fire department inspector.  
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 frame’s finish.  
H. Donotburndriftwoodwhichhasbeeninthe  
ocean or salt water. The salt will corrode  
the firebox and chimney.  
I. Do not burn wood in the area in front of the  
grate.  
J. Do not allow the wood to smoulder or burn  
without flame, since this will produce  
excessive creosote in the unit.  
Door Installation  
(refer to Figure 5)  
The doors on the Cambria fireplace are factory  
installed. To remove the doors, remove the  
finishing trim, then simply pull them 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.  
(See Figure 8, #1)  
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  
and extremely hot fire.  
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). Always use a metallic container to  
dispose of the ashes.  
The chimney shall be inspected at least twice  
a year during the heating season to determine  
when a creosote buildup has occurred.  
WARNING  
When creosote has accumulated it shall be  
removed to reduce the risk of a chimney fire.  
DisposalofAshes: Ashesshould  
be placed in a metal container  
withatightttinglid. Theclosed  
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 dis-  
persed, they should be retained  
in the closed container until  
all cinders have thoroughly  
cooled.  
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:

Glass Cleaning  
The Cambria fireplace is designed to keep the  
glass clean under normal operating condi-  
tions. If the Cambria 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. To clean the glass, there  
are a number of specially designed cleaners  
to remove creosote. Your authorized Lennox  
Hearth Products dealer can recommend a suit-  
ablecleaner. Regularhouseholdglasscleaners  
will not clean creosote. Do not use abrasives  
such as steel pads, steel wool or oven cleaner  
as they will scratch the glass.

Andirons  
The Cambria fireplace is equipped with and-  
irons designed to keep logs from falling into  
the door. It must be replaced only by Lennox  
Hearth Products andirons available from your  
dealer. No other andirons, log retainer or log  
support is sold or recommended by Lennox  
Hearth Products.

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 25. Next, measure the area occupied by  
the fireplace. Note the floor construction and  
consult your local building code to determine  
if additional support is needed.

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 22).

The duct system must be installed respecting  
the following:  
B) Attach the 5” flexible pipe, using the collars provided. Important: Make sure that the plastic  
wrapping around the flexible pipe will not be in contact with the fireplace.  
C) Route the flexible pipe to the chosen location. The ducting system can be installed either in an  
upper room or in a lower room.  
D) Attach the flexible pipe to the blower, using the collars (Figure 25).  
E) Fix the back draft damper to the blower outlet.  
F) Attach a flexible pipe to the fan / flexible pipe adapter (square to round) and stretch it up to the  
location where the heat is required.  
G) At that point, the flexible pipe can be attached to any air distribution grill.  
H) Install the blower heating and cooling thermostat (HCTW) in that part of the house to be heated  
by the hot air duct. The thermostat can be switched to a cooling thermostat and installed in  
the same room as the unit. This thermostat will turn on the blower when the room where the  
fireplace is located becomes too hot.  
1. Removetheplatesclosingupthe8(203mm)

cut the insulation in order to obtain two 8”  
(203mm) diameter openings. Fix the adap-  
tors on the fireplace openings by turning  
clockwise (see Figure 21).  
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: For the grills, the framing  
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.  
This option requires electricity. Make sure that the connections to the blower have been made ac-  
cording to the local codes and comply with their requirements (see instruction provided with the  
thermostat). For more information regarding central forced and ducting, refer to the BISFWK-1  
installation sheet provided with the kit.  
3. The maximum number of elbows in a run  
of duct is two.  
4. Maintainatleast6-1/2(160mm)clearance

THE CHIMNEY SYSTEM  
Chimney Installation Notes  
1. If possible, install an interior chimney as it  
will provide better performance. In areas  
with continuous temperatures below 0°F  
(18°C), the use of an exterior chimney in-  
creasesthelikelihoodofoperatingproblems  
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 an  
outside chimney, are especially prone to  
flow reversal.

the roof, it must be secured using a roof  
brace.  
Table 2 - Flat Roof Framing  
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 mate-  
rial.
