WARNING
Never leave your fireplace unat­tended while it is burning.
CAUTION
Use care when selecting window treatments for windows located near the fireplace. Avoid using combustible flowing window treatments such as curtains on nearby windows that are of sufficient length to be blown in front of an open flame when the
window is opened. Keep any combustible furniture,
materials or decorative pillows at least 48" (1219 mm) from the front fireplace opening.
IMPORTANT
When burning wood, use SOLID NATURAL DRY WELL-SEASONED WOOD ONLY. Hardwoods are recommended (soft woods tend
to burn very quickly).
• DO NOT burn treated wood, charcoal, coal, trash, card­board, driftwood, woods dipped in tar, Christmas tree greens, pitch, pine tar, creosote, chemi­cal chimney cleaners, flame colorants, polystyrene packag­ing, wood products with synthetic binders (i.e. plywood). Plywood, lumber and other misc. materi­als can produce abnormally high temperatures, sputtering and smoking fires and may contain hazardous chemicals to treat insects and fungus.
• Burning unapproved fuels can produce excessive temperatures (overfiring), beyond the design capabilities of the fireplace and may produce excess sparks or may contain hazardous chemi­cals. Burning unapproved fuels can result in a chimney fire, a house fire, personal injury, death or loss of property.
WARNING
Never leave children unattended when there is a fire burning in the fireplace.
WARNING
To avoid the risk of damaging fireplace materials and increas­ing the risk of fire, do not use the fireplace to cook or warm food.
WARNING
Be careful adding wood fuel to the fire or handling fireplace tools such as shovels, tongs or pokers.
WARNING
Never modify or alter your fire­place system in any way. To do so may create a potential fire hazard and void the warranty, listings and approvals of this system.
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.
Neither the manufacturer nor the seller warrants “smoke free” operation nor are we responsible for inadequate system draft caused by mechanical systems, general construction conditions, inadequate chimney heights, adverse wind conditions and/or unusual environmental factors or conditions beyond our control.

THE FIREPLACE
INTRODUCTION
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 building permit and check your local building codes. Install the fireplace only as described in these instructions and using only Lennox Hearth Products components.
• These appliances are not approved for Manufactured Home installations.
• 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. Optional components installation (fan, hot air ducting, etc).
4. Electrical wiring.
5. Framing and finish details.
PARTS REQUIRED
Fireplace model: Cambria
10” diameter chimney - Model Secure Temp
ASHT+,
or Nova Temp steel chimney or 10” (AC) air-cooled manu­factured by Security Chimneys International only, including:
- Chimney lengths
- Elbows (where necessary)
- Associated components as per these installation instructions
HT6103+
insulated stainless
Outside air kit (included)
5” flexible venting system (central forced
air kit) (see section 3.5.2)
UZY5 blower. The blower installation re-
quires that an electrical connection of a 120v electrical box located outside the fireplace be made prior to moving the fireplace in its final position. (see Optional Fireplace Blower on Page 13)
Gravity venting system (see Central Forced
Air Kit on Page 15)
OPERATING THE FIREPLACE
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.
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.
Processed firelogs can be used. Although, do not poke or stir the logs while they are burning. Use only firelogs that have been evaluated for the application of fireplace and refer to firelog warnings and caution markings on packaging prior to use.

First Fires
Before using the fireplace make sure to remove the plastic wrapping on the door. Remove all remaining glue with mild soap. Make sure the doors are properly adjusted, thus avoiding color change to finish due to overheat.
The first 5 or 6 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 odor) due to drying of the paint and steel and any 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.

HEAT OUTPUT
The Cambria™ fireplace is a mid-efficiency fireplace. In spite of the heat that the Cambria fireplace can deliver, it should not replace the main source of heat in your home. This fireplace will bring extra warmth and ambiance to your home by distributing its heat as described further in the manual.
FOR MAXIMUM HEAT OUTPUT, WE STRONGLY RECOMMEND THE INSTALLATION OF HOT AIR DUCTING SYSTEM (See Page 14).
Combustion Control and Chimney Damper
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 chimney damper is controlled by the handle inside the firebox (see Figure 1-A). It is in closed position when the handle is visible (front) and in the open position when not visible (pushed back). The combustion air damper is controlled by the lower handle (see Figure 1-B). The control can be moved from open position at left all the way to the close position at right.
This air combustion control should be in the closed position when the fireplace is not in 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
- Causes and Troubleshooting for more details (on Page 5).

Accelerated Combustion
The maximum heat output for the Cambria fireplace is achieved by burning with the door closed and the combustion air opened. How­ever, it will be necessary to reload with wood every hour. This is the least efficient method of burning the Cambria fireplace. Use caution when burning with the combustion air control wide open. Only burn cordwood in this manner. Small dry pieces of softwood will burn very intensely using this method and may damage the firebox.
This is the recommended mode of operating the Cambria 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 .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 cordwood burning on a bed of hot coals will burn about 1-2 hours. Softwoods may be burned using this method but the combustion time will be substantially reduced.
FOR MAXIMUM HEAT OUTPUT, WE STRONGLY RECOMMEND THE INSTALLATION OF THE OPTIONAL HOT AIR DUCTING SYSTEM.

Building a Fire
A) 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. 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.
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. Criss­crossing 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 de­signed 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.
REFUELING FOR BEST PERFORMANCE
To reload the Cambria fireplace:
A) Completely open the combustion air control
(see Figure 2).
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) Set the combustion air control to the desired
burn level.
Notes:
• For spectacular fire and optimization of the fireplace efficiency, we recommend that the wood load be placed as far back as possible.
• It may be necessary to turn off any blower(s) in operation during the refueling process in 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.
SMOKING – CAUSES AND TROUBLESHOOTING
To reduce the likelihood of smoke coming into the room when opening the door, set the combustion air controls to the left (“Acceler­ated 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:
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 the Cambria fireplace, open a nearby window 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
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.
D. Wet wood Wet or tarred wood will smoulder and smoke
instead of burning properly. Your dealer can help you determine if you have properly seasoned wood for burning.
E. 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.
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 installed with offsets, the minimum chimney height is 18 feet (5.5 m). Additional height will increase draft and will decrease the tendency to smoke.
G. 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, 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.
GAS LOG INSTALLATION
This fireplace is designed to allow the installation of a gas burner. In such a case, the installation must conform with the National Gas Code ANSI Z223.1 and Z21.60. Warning: When using a
gas burner, it is mandatory to keep the chimney outside air register opened.
This fireplace has provision for the installation of a gas pipe and is intended only for connection 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).
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 two 90º elbows. Make sure to have 5-11/16” clearance between the two pipes (see Figure
4).
4. Through the hearth bottom or back openings 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.
Note: In some regions, the use of a flexible gas pipe is allowed. Consult your local authority.

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 and chimney.
D. Keep combustible materials at least 48”
(1.2 m) away from the front of the fireplace opening.
E. Never leave children unattended when
there is a fire burning in the fireplace.
F. Use only untreated wood. Wood protectors,
metallic paper, 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 material such as pressed wood, plywood or lumber. Wood protectors, metallic paper, coal, plastic, waste, sulphur and/or oil will damage the fireplace.
H. Do not burn driftwood which has been in the
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.
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.
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:
6
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.
Warning: The chimney damper must be opened when sweeping the chimney to avoid ash and creosote accumulation in the fireplaces air circulation area.
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.
Dealing With a Chimney Fire
Regular chimney maintenance and inspection can prevent chimney fires. If you have a chimney fire, follow these steps:
IMPORTANT: Close the fireplace door and
1.
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.
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.
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 Brick Replacement (refer to Figure 6)
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:
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
To install the new refractory bricks, follow the above steps in reverse.
DOOR FRAME FINISH 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 frame’s finish.
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)

WARNINGS
• Use only a Lennox Hearth Products glass doors, spe­cifically designed for the Cambria fireplace.
• The fireplace cannot be oper­ated without a door. Consult your dealer to select the cor­rect door model.
• Important! To assure proper alignment of glass doors: Install this fireplace in a square and plumb condition, using shims as necessary at sides and/or bottom.
DOOR ADJUSTMENT
The doors are factory adjusted for proper air tightness and fit. They may need to be readjusted if the alignment has shifted in freight.
To readjust the door side to side position, un­screw the fireplace hinges or the door hinges. Move the doors side to side until the top of the two doors are aligned (Figure 7).
The gaskets’ air-tightness can be adjusted us­ing the adjustment screw located on the slider stoppers (see Figure 8). Turning the screws clockwise will shorten the travel of the slider and increase the pressure on the door side gaskets. This may lead to the doors being harder to lock, so a good adjustment must be found between a good gasket seal and easy door lock (see
Figure 8
, balloon #1).
The door lock can also be adjusted. Remove the front refractory brick and loosen the two screws in the middle front of the firebox bottom. Push or pull on the handle of the door lock. Pushing the handle will tighten the door seal in the center of the fireplace (see Figure 9).

Door Opening Adjustment
The doors opening angle can be adjusted. This allows the doors to slide in the fireplace without interference or friction with the finishing fac­ing, which could damage the paint. The screws located under the bottom hinges (Figure 11) are used as door opening stops. Tightening or loosening these screws will keep the door handle from hitting the finishing facing and won’t allow friction between door gasket and hearth when the door is fully pushed in the fireplace.
Bearing Maintenance
The doors are assembled on retractable slid­ers using roller bearings for easy movement. Cambria fireplace has been designed to ensure that bearing maintenance is easy. Remove the decorative facing by unscrewing the four decorative caps and the four screws holding the facing. Remove the doors by lifting them up from the female hinges (see Figure 5). Remove the slider stoppers (see Figure 8) and take the slider bearing assembly out of the fireplace. Unscrew the nuts to change the bearings (see Figure 10). Original bearing contains no grease to resist heat. Adding grease or chang­ing bearings with greased bearing may cause a malfunction of the slider. Please use Lennox Hearth Products replacement parts only (see Page 25 for part numbers).

Glass Replacement
The glass used for the Cambria™ fireplace is a high temperature ceramic glass (1400°F). If the glass breaks or cracks, it must be replaced with an identical ceramic glass. Tempered glass or ordinary glass will not withstand the high temperatures of the Cambria fireplace. Replacement glass should be purchased from a Lennox Hearth Products dealer (see “Replace­ment Parts” on Page 25).
Do not operate the unit with cracked or broken glass.
Glass Cleaning
The Cambria fireplace is designed to keep the glass clean under normal operating condi­tions. 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 suit­able cleaner. 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.
Remove the doors from the unit (see Door Installation on Page 6) and lay them on a clean nonabrasive 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. This replacement part is available from your Lennox Hearth Products dealer in the dimensions shown in Table 1.

FIREPLACE INSTALLATION
Locating The Fireplace
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 on Page 11).
Marginal Location
Wind Direction
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.
The Cambria™ fireplace may be installed directly on the floor or on a raised base but a minimum of 7 feet 6 inches (2.3 m) measured from the base of the appliance to the ceiling is required.
Location Recommended
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 cause wind turbulence and back drafts in the chimney.
• The least amount of offsets (elbows) pos sible.

Framing, Facing And Mantel
The construction of the framing, facing, and mantel must be in accordance with the stan­dards and the following illustrations (Figures
15 through 20
):
A. Frame the fireplace using 2” x 3” or heavier
lumber.
B. WARNING: Combustible materials can-
not 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 7 feet 6 inches (2286 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 15). If combustible facing is to be used, position the studs back, from the front edge of the fireplace 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. 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 or any other rigid material around the fireplace.
Hearth Extension Requirements -
The Cam­bria™ fireplace may be installed directly on a combustible floor; however, the combustible floor in front of the fireplace must be covered with a 1/2 inch (13 mm) of non-combustible support material (cement board, cement block or other) before applying the finish material (tile, marble, stone, etc.) (see Figures 13 and
14).
WARNING: It is important not to cover the air ventilation opening below the facade trim. (free space - Figure 13).

Elevated fireplace installations require a spe­cial “Z” Metal Safety Strips (field provided), in place of the safety metal strip shown above. The safety strip should extend the full width of the fireplace. When more than one safety strip is used they must overlap by a minimum of 1”.
COLD CLIMATE INSTALLATIONS
Climates where temperatures will fall below 32° F (0° C).
The heating performance of the appliance will vary depending upon the level of insulation, house design, how the appliance is operated, etc.
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. 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).

Optional Fireplace Blower (UZY5)
A heat activated blower is sold as an option. It is designed to be located in the back of the fireplace and increase the air flow around the firebox. It uses regular 120V and must be connected to the main electrical circuit by a qualified electrician. An electrical box must be installed outside the fireplace.
WARNING: Because of the fireplace size and obstructive air venting, we don’t recommend the installation of the blower unless the gravity ducting is installed on the fireplace.
If you wish to adjust the blower speed, an optional variable speed control (VRUW) can be installed in line with the wiring. Again, use a qualified electrician for installation.
To install the blower,
1- Remove the refractory bricks and the and
iron.
2- Remove the metal plates covering the bottom
and back of the hearth firebox.
3- Disconnect the main electric cable from the
blowers by unplugging its two quick connec­tors.

HOT AIR DUCTING INSTALLATION (OPTIONAL)
Different hot air ducting systems can be installed with the Cambria™ fireplace:
• Gravity kit
• Forced air kit The gravity kit is used when the rooms are on same level or floor as the fireplace or on an upper level or floor. If the heat to be distributed is on
a lower level or floor or through the central heat duct of a furnace, then the forced air kit MUST be used.
Gravity Kit
Double hot air outlet including: (See Figure 21)
• 2 ea. telescopic lengths, 8” I.D.
• 2 ea. 90º elbows, 8” I.D.
• 2 ea. hot air outlet kits (grill and frames)
• 2 ea. adaptors
See components list on Page 23.
Only the blower available with the fireplace can be used with the gravity kit.
Frame
Grill
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).
WARNING: The outlet grills

The duct system must be installed respecting the following:
1. Remove the plates closing up the 8” (203mm) diameter holes on top of the fireplace. Then, cut the insulation in order to obtain two 8” (203mm) diameter openings. Fix the adap­tors 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.
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 fan will cause the fireplace to overheat. A furnace duct is only single wall and not double wall as is required for the Cambria™ fireplace hot air exhaust.
7. Use only Lennox Hearth Products grills and components as described in this manual. Other grills or registers 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. All ducts must extend upwards or horizon­tally. 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.
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.
This option requires electricity. Make sure that the connections to the blower have been made ac­cording 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.

OUTSIDE AIR
It is mandatory to install an outside air connec-
tion to the Cambria™ fireplace. The following components are required and are included with the fireplace:
• Outside air kit
• 4” adapter for fi
replace connection
The outside air assembly must be installed ac­cording to the following requirements:
A) Duct length should be kept to a minimum.
The maximum length of a 4” interior diam­eter (100 mm) insulated flexible duct is 20 feet (6.1 m). The duct can be extended to a maximum of 40 feet (12 m) using a 6” interior diameter (150 mm) insulated flexible duct (See note below).
B) The air intake register must not be installed
more than 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, 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.
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 26). 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 27
). 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.

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 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 an outside chimney, are especially prone to flow reversal.
2. The Lennox Hearth Products fireplace model Cambria™ fireplace is listed only with Se­curity Chimneys International Ltd 10” dia. chimney systems model Secure Temp / Nova Temp

or AC.
ASHT+
3. A chimney venting a fireplace shall not vent any other appliance.
4. The minimum chimney height is 15 feet (4.6 m) excluding the fireplace.
5. All chimney installations must include at least one support in order to be able to take any lateral load. The maximum chimney length that can be supported by the fireplace is 12 feet (3.7 m) for Secure Temp

ney. In altitude, add 18” (450 mm) to the chimney for every 2000 feet (600 m) above sea level.
6. 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 wall, roof or building within 10 feet (3m) of it (Figure 28).
7. If the chimney extends higher than 5 feet (1500 mm) above its point of contact with the roof, it must be secured using a roof brace.
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 the chimney.

ANGLED WALL RADIATION SHIELD (RSMI30, RSMI45, AC10RSMI30)
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
In cold climate locations, 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:

/ Nova Temp
HT6103+
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 when the chimney height exceeds 12 feet (3.7 m).
Table 6 gives maximum height of supported chimney.
NOTE: For the AC chimney, a support section (AC10SL) must be used every 20 feet (6 m) or an universal support every 15 feet (4.5 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 38).
