Test gauge connections are provided on the front of the millivolt gas control valve, identified IN for the inlet and OUT for the manifold side (see Figures 4 or 5 on Page 5). A 1/8" NPT Test gauge connection is provided at the inlet and outlet (manifold) ports on the electronic gas control valve (see Figure 3 on Page 5).
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 approved for installations at elevations of 0-4500 feet (0-1372 meters) above sea level using the standard burner orifice sizes (marked with an "*" in Table 7).
4
At the time of installation, it must be determined if the appliance needs to be derated. Contact your local gas supplier for deration requirements 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 6.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Gas Controls/Control Compartment
Access
The gas controls can be found behind the control compartment access door.
Removing Control Compartment Door:
Open the door by gently liftint it upward until the hook catches on boths sides clear the locating slots. Then pull door out to remove.
On millivolt systems, the piezo igniter, HI/LO flame adjustment knob, and pilot and main gas OFF/ON control knob are located below the glass panel enclosure. The gas valve for electronic systems is also located below the glass enclosure panel. See Figure 1.

OPERATION AND CARE OF YOUR APPLIANCE
The standard controls for appliance operation are located behind the panel below the appliance front glass enclosure panel (see Figure 1). Optional control switches are also available (see Page 14 - Remote Wall Switch, Remote Control or Wall Thermostat).
Operation of millivolt and electronic gas control systems are different. Before lighting and operating your appliance determine if you have a millivolt or electronic appliance. Familiarize yourself with the gas control valve that your appliance uses. Refer to Figure 1 for access to the gas control valve.
Millivolt Appliances - Appliances with Millivolt systems will be fitted with the gas control valve shown in Figures 4 or 5.
Electronic Appliances - Appliances with electronic systems will be fitted with the electronic valve shown in Figure 3.
Millivolt Appliances - To light millivolt appliances refer to the detailed lighting instructions found on Pages 18 & 19 . Millivolt appliance lighting instructions may also be found on the pull out lighting instruction labels attached to the gas control valve.
Millivolt appliances are fitted with an OFF/ON Rocker Switch located behind the control compartment access door, below the appliance front glass enclosure panel (see Figure 2 for location). Once the pilot is lit, the OFF/ON rocker switch will control the appliance OFF/ON burner operation. To operate: Toggle the switch between its ON and OFF positions.
If your millivolt appliance is equipped with an optional remote switch kit (wall switch, remote control or wall thermostat) and the pilot is lit, the appliance main burner may be turned on and off using the optional switch. When using an optional remote switch, turn off the standard OFF/ON switch.
Note: To prevent excessive resistance in burner circuit (which can cause burner operation problems), only one burner control switch should be wired to valve. Therefore, if an optional control switch is installed, the standard Off/On switch and wires should be removed.

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).
6
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 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 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 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 25 & 26 for ordering information).
Re-Install Embers, Logs and Vermiculite - Carefully follow placement instructions on Pages 8 to 10). 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 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 flame shown in Figures 10 & 11 and as described in Flame Appearance and Sooting on Page 11. 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, cat. no. 90L74. 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 4). If the surface later becomes stained or marred, it may be lightly sanded and touched up with spray paint.
