INTRODUCTION

The Fireplace models covered in this manual are Direct-Vent sealed combustion gas ﬁ replace 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 control valve with piezo ignition system provides safe, efﬁ cient 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 an electronic intermittent pilot system provides safe, efﬁ cient operation. External electrical power is required to operate these appliances.

lating air passage ways of appliance be kept clean. See Maintenance instructions on Page 6.

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 trafﬁ c and away from furniture and draperies. Locate furniture and window coverings accordingly.

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

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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.

Inspect Venting System

The appliance and venting system should be thoroughly inspected before initial use and at least annually by a qualiﬁ ed 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 qualiﬁ ed 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 Lower Control Compartment

Keep lower control compartment clean by vacuuming or brushing it out at least twice a year (also clean the air venturi with a brush or wire). More frequent cleaning may be required due to accumulation of lint from carpeting, bedding materials, pet hair, spider webs, etc. It

is very important that control compartments, burners, circulating air passageways and air venturi on the appliance are NOT obstructed in any way.

Cleaning Glass

(see Front Glass Enclosure Panel, Removal and Installation on Page 7) Note: Clean glass

after ﬁ rst two weeks of operation (after Burn-In period is over) and then only when necessary and when the ﬁ replace 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 ﬁ lm 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 ﬁ 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 ﬁ rmly.

Clean Logs And Burner

Carefully remove the logs (use care when handling the ﬁ ber 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 22 & 23 for ordering information).

Re-Install Embers, Logs and Vermiculite

- Carefully follow placement instructions on

Pages 8 to 10 ). All logs should ﬁ t onto corresponding pins and/or log stoppers. This will ensure a proper ﬂ ame and safe combustion.

Inspect Wiring

Refer to wiring diagrams on Page 13.

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 ﬂ ame shown in Figures 10 &

11 and as described in Flame Appearance and Sooting on Page 11. The Homeowner must

contact a qualiﬁ ed service technician at once if any abnormal condition is observed.

Small Area Paint Touch-up

The ﬁ nish of the appliance is a high quality powdercoat. Only use factory supplied powdercoat paint kit for touch-ups. Paint is available at your local authorized Lennox Hearth Products dealer (cat. no. 90L74). Never attempt to paint a hot ﬁ replace.

Do not attempt to repaint the appliance until the ﬁ nish 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.
