To light electronic appliances refer to the detailed lighting instructions found on Pages 24 and 25 of these instructions. Electronic appliance lighting instructions may also be found on the pull out lighting instruction labels attached to the gas control valve.

If your electronic appliance is equipped with an optional remote wall switch or remote control kit the appliance main burner may be turned on and off with the wall switch or remote control.

Variable Flame Height Adjustment (Millivolt Appliances only)

All Millivolt appliances are equipped with a variable gas control valve. Flame height for these models may be adjusted through a range between ﬁxed low and high settings while the appliance is in operation. Adjust the ﬂame height as desired after lighting the appliance by rotating the variable adjustment control knob (HI/LO) located on the front of the valve (refer to Figure 2).

VENT OPERATION TEST

A vent operation test is required as part of the installation to verify that proper venting conditions exist and should be done periodically to ensure nothing has changed that would affect proper venting of the appliance.

Procedure:

1. ENSURE APPLIANCE IS OFF (PILOT ONLY) AND COOL.

2. Open both latches on one of the glass enclosure doors and slightly prop it open at the bottom (approx. 1/4” gap). See Figure 6 on Page 12.

3. Turn on all the exhaust fans in the dwelling (and any other appliances which remove air from the dwelling, such as a furnace or clothes dryer, etc)..

4. Ensure that all the doors and windows in the room where the ﬁreplace is located are closed.

5. Light the appliance (see Lighting Instruc- tions, Pages 22 to 25). Adjust ﬂame height to highest setting and operate for approximately 5-10 minutes. Do not leave appliance unattended.

6. Take a smoke producing device and move it along the bottom edge of the glass door (where it is cracked open). If smoke is drawn into the ﬁrebox, the vent operation is adequate.

SPILL SWITCH OPERATION

Manual-Reset (safety limit) Spill Switch

This appliance is equipped with a (safety limit) spill switch that is designed to "trip" and discon-

nect the burner circuit if ﬂue spillage occurs (because of improper venting of combustion products or vent blockage). If, during appliance operation, the burner ﬂame goes out (independently of the burner OFF/ON wall switch), it may be due to the operation of this (safety limit) spill switch. If this switch "trips" it will need to be manually reset by pressing the reset button on switch (see Figure 4).

Procedure to Reset (safety limit) Spill Switch ALLOW APPLIANCE TO COOL COMPLETELY

BEFORE ACCESSING AND RESETTING

To access the spill switch:

1. Pull off the top louvered panel.

2. Locate and press the red reset button on the switch (it will click & lock in).

The appliance should then relight and remain lit. If this does not occur, turn off the appli-

ance and call a qualiﬁed service technician.

Outside Combustion Air Controls

Many appliances are equipped, when installed, with an outside (make-up air) vent system that is designed to provide the appliance with outside make-up air for combustion when in operation.

The outside air control lever for the outside air system is standard on all appliances but should not be operated if the complete system is not installed. Refer to Figure 5. When the complete outside air vent system is installed, the installer will remove the securing screw from the combustion air control lever located on the right side of the ﬁreplace opening.

If the securing screw has not been 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.

WARNING

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

To open the outside air shutter, open the bottom control access panel, and pull the outside air control lever all the way out. The outside air shutter should be fully open when the ﬁreplace is in use and completely closed when the ﬁreplace is not being used. Closing it when not in use will prevent outside cold air from entering the dwelling.

The hand operated outside air control lever is located on the right side of the ﬁreplace opening. See Figure 5.

To open the outside air , open the bottom control access panel, reach into the gap between the ﬁrebox bottom and pull the outside air control lever all the way out.

The outside air shutter should be fully open when the ﬁreplace is in use and completely closed when the ﬁreplace is not being used. Closing it when not in use will prevent outside cold air from entering the dwelling.

Operate the actuator through several cycles including the closed position. Ensuring proper operation and freedom of movement. Return the actuator arm to the closed position.

MAINTENANCE (See Maintenance Schedule, Page 26)

Refer to the maintenance schedule for maintenance tasks, procedures, frequency and by whom they should be performed. Always verify proper operation of the appliance after servicing.

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 adéquatement 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 exhaust passage is 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.

Cleaning Glass

(see Front Glass Enclosure Panel, Removal and Installation on Page 10)

NOTE: Clean glass after ﬁrst two weeks of operation (after Burn-In period is over) and then only when necessary and when the ﬁreplace is cool. Wipe surface with clean, dampened, soft cloth. Follow with a dry, soft towel as desired. Take care not to scratch the glass surface.

IMPORTANT: Do not use abrasive cleaners on glass. Never clean the glass when it is hot.

The viewing glass should be cleaned periodically to remove any build-up caused from the following:

• During start-up, it is normal for condensation to form on the inside of the glass (this condensation and fog will usually disappear in a few minutes). The moisture can cause lint, dust and other airborne particles to cling to the glass surface.

• Initial curing of the high temperature paint

and burning off of lubricants used in the manufacturing process may result in a ﬁlm on the glass.

• A white coating may form on the glass as

a result of impurities and minerals in the fuel.

It is recommended that the glass be cleaned two or three times during each year, depending on the circumstances present. The following cleaning solutions are approved for use to clean glass:

• Non-ammonia based household cleaner

• 50%-50% mix of white vinegar and water

• Gas replace/stove glass cleaner

Inspect Glass Gasket - Visually inspect the gasket on the backside of the glass enclosure panels. The gasket surface must be clean, free of irregularities and seated ﬁrmly.

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.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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 29 for ordering information).

Re-Install Embers, Logs and Vermiculite

Carefully follow placement instructions on Pages 12 to 15). 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 17.

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 15 and as described in ﬂame Appearance and Sooting on Page 15. Refer to Figures 17 and 18 on Page 16 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.

If the surface later becomes stained or marred, it may be lightly sanded and touched up with spray paint.

BURNER ADJUSTMENTS

(QUALIFIED TECHNICIANS ONLY)

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 yellowish-orange 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.

(Valve Access Side)

Figure 14

(Valve Access Side)

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.

• If there are offsets in the vent system, the air

shutter opening may need to be increased.

• 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.

Vermiculite

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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

Burner Air Shutter Adjustment Procedure

WARNING

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

• Ensure front glass panel are in place and sealed during adjustment.

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.

1. Locate adjustment rod and adjust air shutter

to the standard setting as shown in Figure 16 (adjustment rod is located in the lower

control area). NOTE: Rotating the adjustment rod counterclockwise decreases air and clockwise increases air.

2. Light appliance (follow lighting procedure on

lighting label in control compartment or see care and operation instructions manual).

3. Allow the burner to operate for at least 15 min-

utes while observing the ﬂame continuously to ensure that the proper ﬂame appearance has been achieved (see Figure 15). If the following conditions are present, adjust accordingly.

• If ame appears weak or sooty, adjust

the air shutter, incremen tally, to a more open position until the proper ﬂame appearance is achieved.

• If ame stays lowered blue, adjust the

air shutter, incrementally, to a more closed position until the proper ﬂame appearance is achieved.

4. Leave the control knob (off/pilot/on) in the

ON position and the burner OFF/ON switch OFF (and remote switches, if applicable).

5. When satisﬁed that the burner ﬂame appear-

ance is normal, close the lower control compartment door.

TROUBLESHOOTING

NOTE: Before troubleshooting the gas control system, Ensure external gas shut off valve, located at gas supply inlet, (and wall switch, iff applicable), is in the “ON” position.

Important: Valve system troubleshooting should only be accomplished by a qualiﬁed service technician.

TROUBLESHOOTING GUIDE - MILLIVOLT GAS CONTROL SYSTEM

SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION

1. Spark igniter will not light pilot after

repeated triggering of igniter button.

WARNING: if the pilot will not light

after 1 minute of attempting, wait for at least 5 minutes for gas to clear before attempting again.

2. Pilot will not stay lit after

carefully following the lighting instructions.

3. Pilot burning, no gas to burner, Valve

knob “ON,” and the (standard) burner OFF/ON switch is “ON." Read important note below.

IMPORTANT NOTE: If an optional

*remote switch is used for burner operation, if the standard burner

OFF/ON switch is still installed on

appliance it must be in the "OFF" position.

*Optional remote switch kits - wall

switch or timer, or remote control.

4. Frequent pilot/burner outage prob-

lem.

A. Defective igniter (no spark at electrode).

B. Defective or misaligned electrode at pilot

(spark at electrode).

C. Gas supply pressure errant. Check inlet gas pressure. It should be within the limits

D. Pilot oriﬁce plugged. Clean or replace pilot oriﬁce. A. Defective pilot generator

(thermocouple).

A. Wall switch or wires defective. Check wall switch and wires for proper connections.

B. Thermopile may not be generating suf-

ﬁcient millivolts.

C. Plugged burner oriﬁce. Check burner oriﬁce for blockage and remove. D. OFF/ON Switch & *Remote Switch are in

the "ON" position resulting in excessive resistance.

A. Pilot ﬂame may be too low or blowing (high)

causing the pilot/valve safety to drop out.

Check for spark at electrode and pilot; if no spark and electrode wire is properly connected, replace igniter.

Using a match, light pilot. If pilot lights, turn off pilot and trigger the igniter button again. If pilot lights, an improper gas mixture caused the bad lighting and a longer purge period is recommended. If pilot will not light – check gap at electrode and pilot – should be 1/8" to have a strong spark. If gap measures 1/8", replace pilot (see Figure 17 on Page 16).

Check pilot ﬂame, it must impinge on thermocouple (see Figure 17 on Page 16). Clean and/or adjust pilot for maximum ﬂame impingement on thermocouple. Ensure that the connection between the valve and thermocouple are tight and secure.

Jumper wire across terminals at wall switch, if burner comes on, replace defective wall switch. If okay, jumper wires across wall switch wires at valve, if burner comes on, wires are faulty or connections are bad.

Check thermopile with millivolt meter. Take reading at thermopile terminals of gas valve. Should read 325 millivolts minimum with optional wall switch “OFF.” Replace faulty thermopile if reading is below speciﬁed minimum.

When turning on the burner using a *remote switch, ensure that the standard OFF/ON switch is in the "OFF" position. If both switches are in the ON position, it may result in excessive resistance (& millivolt drainage) and the burner may not come on.

Clean and/or adjust pilot ﬂame for maximum ﬂame impingement on thermocouple (see Figure 17 on

Page 16).
