Introduction

The Fireplace models covered in this manual are Direct-Vent sealed combustion gas fireplace heaters designed for residential application. Direct-Vent appliances operate with the combustion chamber completely isolated from the indoor environment.

All air for combustion is brought in from the outside and exhaust gases are vented through the same direct vent, co-axial (intake/exhaust) vent system.

The Millivolt appliances have a millivolt gas controlvalve with piezo ignition system provides safe, efficient operation. If any optional accessories which require electrical power are being installed, the electrical power must be provided at the time of appliance installation.

The Electronic appliances have a battery backed up electronic intermittent pilot system that provides safe, efficient operation. No external electrical power is required to operate these appliances.

These appliances comply with National Safety Standards and are tested and listed by OmniTest Laboratories (Report No. 116-F-50-5) to ANSI ZZ21.88 (in Canada, CSA-2.33), and CAN/CGA-2.17-M91 in both USA and Canada, as vented gas fireplace heaters.

The Installation must conform to local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54-latest edition, or the Natural Gas and Propane Installation Code, CSA B149.1-latest edition. The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, the latest edition of the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.1 - latest editions.

General Information

Note: Installation and repair should be performed by a qualified service person. The appliance should be inspected annually by a qualified professional service technician. More frequent inspections and cleanings may be required due to excessive lint from carpeting, bedding material, etc.

It is imperative that the control compartment, burners and circulating air passage ways of appliance be kept clean. See Maintenance instructions on Page 5.

S'assurer que le brùleur et le compartiment des commandes sont propres. Voir les instructions d'installation et d'utilisation qui accompagnent l'appareil.

Provide adequate clearances around air openings and adequate accessibility clearance for service and proper operation. Never obstruct the front openings of the appliance.

Due to high temperatures the appliance should be located out of traffic and away from furniture and draperies. Locate furniture and window coverings accordingly.

These fireplaces are designed as supplemental heaters. Therefore, it is advisable to have an alternate heat source when installed in a dwelling.

These appliances are designed to operate on natural gas or propane gas only. The use of other fuels or combination of fuels will degrade the performance of this system and may be dangerous.

A 1/8" NPT Test gauge connection is provided at the inlet and outlet (manifold) ports on the electronic gas control valve (see Figure 4 on Page 4).

These appliances must be isolated from the gas supply piping system (by closing their individual manual shut-off valve) during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

These appliances and their individual shut-off valves must be disconnected from the gas supply piping system during any pressure testing of that system at pressures greater than 1/2 psig (3.5 kPa).

Orifice Sizes - Sea Level to High Altitude (All Models): These appliances are tested and approvedforinstallations atelevations of0-4500 feet (0-1372 meters) above sea level using the standard burner orifice sizes (marked with an "*" in Table 7).

At the time of installation, it must be determined if the appliance needs to be derated. Contact yourlocalgassupplierforderationrequirements for your area.

Deration - At higher elevations, the amount of BTU fuel value delivered must be reduced by either using gas that has been derated by the gas company or by changing the burner orifice to a smaller size as regulated by the local authorities having jurisdiction and by the (USA) National Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition or, in Canada, the CAN1-B149.1 and .2 codes - latest edition.

Burn-in Period

During the first few fires of this appliance there will be some odor due to the curing of the paint and burning off of lubricants used in the manufacturing process.

Depending on your use, the burn-in period may take a few hours or a few days.

KEEP YOUR HOUSE WELL VENTILATED DURING THE CURING PROCESS. THE ODOR AND HAZE EMITTED DURING THE CURING PROCESS CAN BE QUITE NOTICEABLE AND MAY SET OFF A SMOKE DETECTOR.

If an optional blower is installed, Do Not turn it on during the Burn-In period.

A white film may develop on the glass front during the first few fires as part of the curing process. The glass should be kept clean during the first two weeks of use to prevent the film from baking on (making it very difficult to remove). See Cleaning Glass on Page 5.

Gas Controls/Control Compartment

Access

The gas controls can be found behind the control compartment access door.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Removing Control Compartment Door:

MAINTENANCE

(See Maintenance Schedule, Page 22)

Refertothemaintenancescheduleformaintenance 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 before servicing the appliance.

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

IMPORTANT: Always verify proper operation after servicing.

Before re-lighting the fireplace, refer to the lighting instructions in this manual. Instructions are also found on pull-out panels located below the glass door 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).

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 6 )

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 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 & 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.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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 26 & 27 for ordering information).

Re-Install Embers and Logs - Carefully follow placement instructions on Pages 7 to 9 ). 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 12.

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

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 9 & 10 and as described in Flame Appearance and Sooting on Page 10. The Homeowner must contact a qualified service technician at once if any abnormal condition is observed.

Small Area Paint Touch-up

The finish of the appliance is a high-qual- ity powdercoat. Only use factory supplied powdercoat paint kit for touch-ups. Paint is available at your local authorized 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 3 ). 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. If after a short period the flame stays lowered 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 openings 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 yellow- ish-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, 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.

•Themore offsets in the ventsystem, 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 open position, then operate the appliance for a few moreminutestoensurethattheflamenormalizes 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.

Air Shutter Adjustment Guidelines:

Burner Air Shutter Adjustment Procedure

1. Locate adjustment rod and adjust air shutter to the standard setting as shown in Figure 11 (adjustment rod is located in the lower control compartment). Note: Rotating the adjustment rod clockwise decreases air and counterclockwise increases air.

2.Light appliance (follow lighting procedure on lighting label in control compartment or see homeowners manual).

3.Allowtheburnertooperateforatleast15minutes while observing the flame continuously to ensure that the proper flame appearance has been achieved (see Figure 9 or 10). 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 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 (& remote switches, if applicable).

5.When satisfied that the burner flame appearance is normal, close the lower control compartment door.
