•

glass doors with your hands while the ﬁreplace is in use.

• Do not operate appliance with

the glass doors cracked or broken.

• Do not use abrasive cleaners.

Never clean the glass when it is hot.

• Do not strike or slam shut

optional glass doors.

• Fireplaces equipped with

optional accessory doors should be operated only with the doors fully open or fully closed (Figure 4). This appliance may only be ﬁtted with doors certiﬁed for use with the appliance.

DAMPER AND COMBUSTION AIR CONTROLS

This appliance is ﬁtted with a manually controlled vent damper. The vent damper should be closed when the appliance is not in use to prevent cold air from entering the home through the venting system. The damper is controlled through the use of a control lever located within the appliance opening at the top center in front of the ﬁrebox lintel (see Figure 6).

The control lever snaps into place at either extreme of its range of motion. When locked in position all the way to the right, the damper is open. When locked in position all the way to the left, the damper is closed.

The damper lever actuates a switch, (see wiring

diagram) which will prevent the appliance main

burner from lighting unless the damper is locked open. The appliance ﬂue damper must always remain open when operating.

WARNING

Do not operate the shutoff lever unless a complete outside air vent system has been installed with your appliance.

If your screw is not removed and you have reason to believe that you have a complete outside air system, contact your distributor to have your appliance inspected for the presence of the complete system. DO NOT assume that you have this system in place because you have an actuating lever present on your appliance front face.

To operate, push the end of the actuator to the left as shown in Figure 6, until it "pops" free of

its "locked" position. Pull the actuator forward

to open the combustion air door, and push it

back to close. To "lock" the combustion air

door closed, ensure the actuator is pushed all the way back, then push the end of the actuators to the right until the step in the actuator moves behind the appliance front face within the slotted opening.

To provide outside combustion air to your appliance while it is in operation, locate the combustion air actuator along the right side of the appliance opening (Figure 6).

MAINTENANCE

(See Maintenance Schedule, Page 21)

Refer to the maintenance schedule for maintenance tasks, procedures, periodicity and by whom they should be performed.

WARNING

Turn off gas and electrical power to the ﬁreplace and allow it to cool before cleaning or servicing the appliance.

CAUTION: Wear gloves and safety glasses for protection while doing required maintenance.

Verify proper operation after servicing. S'assurer que l'appareil fonctionne adé-

quatement une fois l'entretien terminé. Always turn off gas to the pilot (millivolt

appliances) before cleaning. Before relighting, refer to the lighting instructions in this manual. Instructions are also found on a pull-out panel located in the control compartment.

Always keep the appliance area clear and free from combustible materials, gasoline and other ﬂammable vapors and liquids.

Inspect Venting System - The appliance and

venting system should be thoroughly inspected before initial use and at least annually by a qualiﬁed service technician (inspection should include ensuring that venting unobstructed and vent components are properly assembled and

not damaged). Homeowner must contact a qualiﬁed service technician at once if any abnormal condition is observed.

If the venting system is disassembled for any reason, a qualiﬁed service technician should follow vent installation instructions for proper reassembly and proper sealing of the venting system components. However, more frequent periodic inspections and cleanings should be performed by the homeowner.

Clean Control Compartment - Keep control compartment clean by vacuuming or brushing at least twice a year. More frequent cleaning may be required due to excessive lint from carpeting, bedding materials, etc. It is important that control compartments, burners and circulating air passageways of the appliance be kept clean.

Clean Logs And Burner - Carefully remove the logs (use care when handling the ﬁber logs, as

they become quite fragile after curing). Vacuum out any foreign matter (lint, carbon, etc). on

the burner. Ensure the burner ports are “open.” Remove any carbon deposits from the under side of the logs using a vacuum cleaner, or a

soft bristled brush (i.e. paint brush).

Note: Improper positioning of logs can create carbon build-up and will alter the performance of the appliance.

Replacing Logs - If the logs become damaged by accident or improper handling and need replacement, use only the proper replacement logs from manufacturer (see Page 24 for order-

ing information).

Re-Install Embers and Logs - Carefully follow placement instructions on Pages 10 and 11. All logs should ﬁt onto corresponding pins and/or log stoppers. This will ensure a proper ﬂame and safe combustion.

Inspect Wiring (Refer to wiring diagrams on

Page 14) -

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

ATTENTION: Au moment de l'entretien des commandes, étiquetez tous les fils avant de les débrancher. Des erreurs de cáblage peuvent entraîner un fonctionnement inadéquat et dangereux.

Inspect and clean all wire connections. Ensure that there is no melting or damage. Inspection should include:

• Terminals at the Valve

• OFF/ON Switch

• (Optional Control Switch) Remote Control

or Remote Wall Switch Kit

Inspect Burner Flame and Pilot Flame Appearance

Periodically do a visual check of the burner ﬂame and the pilot ﬂame. Ensure that the burner ﬂame appearance resembles the ﬂame shown in Figure 14 on Page 12 and as described in ﬂame Appearance and Sooting on Page 12. Refer to Figures 16 and 17 on Page 13 for more information about the pilot ﬂame appearance. Contact a qualiﬁed service technician at once if any abnormal condition is observed.

Small Area Paint Touch-up

Only use a factory supplied paint kit for touchups. Paint is available at your local Lennox Hearth Products dealer. Never attempt to paint a hot ﬁreplace.

Do not attempt to repaint the appliance until the ﬁnish is completely cured (see Burn-In Period on Page 6). If the surface later becomes stained or marred, it may be lightly sanded and touched up with spray paint.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

LOGS, GLOWING EMBERS AND VOLCANIC STONE PLACEMENT

WARNING

• DO NOT attempt to install the

logs until the appliance installation has been completed, the gas line connected and tested for leaks and the initial burner operation has been checked out.

• The size and position of the log set was engineered to give the appliance a safe, reliable and attractive ﬂame pattern. Any attempt to use a different log set in the ﬁreplace will void the warranty and will result in incomplete combustion, sooting, and poor ﬂame quality.

• Logs get very hot and will remain hot up to one hour after gas supply is turned off. Handle only when logs are cool. Turn off all electricity to the appliance before you install grate, volcanic stone, embers and logs.

• This appliance is not designed

to burn wood. Any attempt to do so could cause irreparable damage to the appliance and prove hazardous to your safety.

• If logs are not installed

according to the log installation instructions, flame impingement and improper combustion could occur and result in soot and/or excessive production of carbon monoxide (CO), a colorless, odorless, toxic gas.

Page 11

Flame Appearance and Sooting

Proper ﬂame appearance is a ﬂame which is blue at the base and becomes yellowish-orange in the body of the ﬂame.

When the appliance is ﬁrst lit, the entire ﬂame may be blue and will gradually turn yellowishorange during the ﬁrst 15 minutes of operation. After 15 minutes of operation, if the ﬂame is blue, or if the ﬂame is orange with evidence of

sooting (black tip), the air shutter opening may

need to be adjusted.

If the air shutter opening is closed too far, sooting may develop. Sooting is indicated by black puffs developing at the tips of very long orange ﬂames. Sooting results in black deposits forming on the logs, appliance inside surfaces and on exterior surfaces adjacent to the vent termination.

Sooting is caused by incomplete combustion in the ﬂames and lack of combustion air entering the air shutter opening. To achieve a warm yellowish-orange ﬂame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes.

Air Shutter Adjustment Guidelines

• If there is smoke or soot present, rst check

the log set positioning to ensure that the ﬂames are not impinging on any of the logs. If the log set is properly positioned and a sooting condition still exists, then the air shutter opening should be increased.

• The more offsets in the vent system, the larger

the air shutter opening will need to be.

• An appliance operated with the air shutter

opened too far, may have ﬂames that appear blue and transparent. These weak, blue and transparent ﬂames are termed anemic.

• Propane models may exhibit ames which

candle or appear stringy. If this is present and persists, adjust the air shutter to a more closed position, then operate the appliance for a few more minutes to ensure that the ﬂame normalizes and the ﬂames do not appear sooty.

Burner Flame Adjustments

To adjust the ﬂame, position the air shutter to the nominal setting (Figure 15). Allow the burner

to operate for at least 30 minutes. Observe the

ﬂame continuously. If it appears weak or sooty as previously described, adjust the air shutter open or closed until desired effect is achieved.

NOTE: If the ﬂame still appears anemic with the air shutter closed all the way (usually a result of lengthy vertical venting runs), turn off the appliance, turn off the gas supply, wait for the parts to cool and access the air shutter. The shutter is prevented from actually closing by a tab that is bent over into the opening. Remove this obstruction by bending back. Reassemble and restart the appliance and after 30 minutes reobserve the ﬂame. Adjust the air shutter as described.

CAUTION

• Soot will be produced if the

air shutter is closed too much. Any damage due to carboning resulting from improperly setting the air shutter is not covered under the warranty.

• The air shutter door and nearby appliance surfaces are hot. Exercise caution to avoid injury while adjusting ﬂame appearance.

WARNING

• Air shutter adjustment should only be performed by a qualiﬁed professional service technician.
