Millivolt Models - The millivolt appliances are manually controlled and feature a spark igniter (piezo) that allows the appliance's pilot gas to be lit without the use of matches or batteries. This system provides continued service in the event of a power outage.

Millivolt models come standard with a manuallymodulated gas valve; ﬂame appearance and heat output can be controlled at the gas valve. The BTU Input for these appliances is shown in Table 1.

Electronic Models - Electronic models have a ﬁxed rate gas valve. Input of electronic models is shown in Table 1.

Variable Flame Height Adjustment (Millivolt appliances only)

1. 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, alternately, while the appliance is in operation.

Adjust the ﬂame height as desired after lighting the appliance by rotating the variable adjustment control knob located on the front of the valve

(refer to Figure 2).

2. When lit for the ﬁrst time, this appliance will

emit a slight odor for an hour or two. This is due to the “burn-in” of internal paints and lubricants used in the manufacturing process.

3. Keep lower 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 and clear of obstruction of venting and combustion air.

4. Always turn off gas to the pilot (millivolt appliances) before cleaning. Before re-lighting, refer to the lighting instructions in this manual. Instructions are also found on a pull-out panel located on the ﬂoor of the appliance.

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

6. Remember, Millivolt appliances have a continuous burning pilot ﬂame. Exercise caution when using products with combustible vapors.

Millivolt units are not provided with any factory-installed controls; therefore, one of the optional control switches is required to operate the unit (ON/OFF Wall Switch, Unit-Mountable ON/OFF Switch, Thermostat, Remote Control). See “Accessories” in this manual for details.

Once the pilot is lighted, use the switch or remote control to turn the appliance ON and OFF.

(See Maintenance Schedule, Page 25 )

Refer to the maintenance schedule for maintenance tasks, procedures, periodicity 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.

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 or intake passages are 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 11).

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

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

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

• 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 heating season, 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 ﬁreplace/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.

Replacing Logs

If the logs become damaged by accident or improper handling and need replacement, use only the proper replacement logs from manufacturer (see Pages 13,14 and 15 for ordering information).

Reinstall Embers and Logs

Carefully follow placement instructions on Pages 12 through 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 18.

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) Wall Thermostat, Remote Control or Remote Wall Switch Kit

Inspect Burner Flame Appearance

Ensure that the burner ﬂame appearance resembles the ﬂame shown in Figures 10, 11

and 12 and as described in Flame Appearance and Sooting on Page 16. The Homeowner must

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 authorized Lennox Hearth Products dealer. Never attempt to paint a hot ﬁreplace.

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 yellowishorange during the ﬁrst 15 minutes of operation. If the ﬂame remains 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.

Figure 10 : MPD-3328

Air Shutter Adjustment Guidelines

• If there is smoke or soot present, ﬁrst 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 ﬂames 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.

The following chart is provided to aid you in achieving the correct air shutter adjustment for your installation.

on lighting label in control compartment or in this Care and Operation Instructions).

3. Allow the burner to operate for at least 15

minutes while observing the ﬂame continuously to ensure that the proper ﬂame appearance has been achieved. If the following conditions are present, adjust accordingly.

• If ﬂame appears weak or sooty, adjust the air shutter, incrementally, to a more open position until the proper ﬂame appearance is achieved.

• If ﬂame remains blue, adjust the air shutter, incrementally, to a more closed position until the proper ﬂame appearance is achieved.

4. When satisﬁed that the burner ﬂame appear-

ance is normal, turn the ON/OFF control (unit-mounted or remote switch, depending on your application) to the OFF position.

5. Reinstall the lower control access panel,

then proceed to ﬁnish the installation.

To light the burner, rotate the gas valve control knob counterclockwise to the ON position (“ON” will be at the top side of the valve).

Turn the ON/OFF control (unit-mounted or remote switch, depending on your application) to the ON position.

The pilot ﬂame should be steady, not lifting or ﬂoating. Flame should be blue in color with traces of orange at the outer edge.

The top 3/8" (10 mm) at the pilot generator (thermopile) and the top 1/8" minimum (tip) of the quick drop out thermocouple should be engulfed in the pilot ﬂame.

The ﬂame should project 1" (25 mm) beyond the hood at all three ports (see Figure 14). Replace logs if removed for pilot inspection.

TROUBLESHOOTING GUIDE: MILLIVOLT GAS CONTROL SYSTEM

Note: Before troubleshooting the gas control system, make sure the external gas shut off valve (located at gas supply inlet) is in the “ON” position.

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

1. Spark ignitor will not light

pilot after repeated triggering of ignitor button.

2. Pilot will not stay lit after

carefully following the lighting instructions.

3. Pilot burning, no gas to

burner, Valve knob “ON,” Wall Switch “ON.”

POSSIBLE CAUSES

A. Defective ignitor

(no spark at electrode).

B. Defective or misaligned electrode

at pilot (spark at electrode).

C. Gas supply pressure errant.

D. Pilot oriﬁce plugged.

A. Defective pilot generator

(thermocouple).

A. Wall switch or wires defective.

CORRECTIVE ACTIONSYMPTOM

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

Using a match, light pilot. If pilot lights, turn off pilot and trigger the ignitor 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 (Figure 14 on page 17).

Check inlet gas pressure. It should be within the limits as marked on the rating plate.

Clean or replace pilot oriﬁce.

Check pilot ﬂame, it must impinge on thermocouple (Figure 14 on page 17). Clean and/or adjust pilot for maximum ﬂame impingement on thermocouple. Ensure that the connection between the valve and thermocouple are tight and secure.

Check wall switch and wires for proper connections. 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.

4. Frequent pilot/burner outage

problem.

B. Thermopile may not be generating

sufﬁcient millivoltage.

C. Plugged burner oriﬁce.

A. Pilot ﬂame may be too low or

blowing (high) causing the pilot/ valve safety to drop out.

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.

Check burner oriﬁce for stoppage and remove.

Clean and/or adjust pilot ﬂame for maximum ﬂame impingement on thermocouple (Figure 14 on page 17).
