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
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.
Reinstalling Control Compartment Door:
To reinstall, insert the hook catches on each side of the door into the corresponding slots in the control compartment opening, then gently push forward and side down until it locks in place.

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
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
NOTE: The top louvered panel and the bottom louvered control panel door remove and install the same way as follows:
The gas controls can be found behind the control compartment access door.
Removing Control Compartment Door:
Open the door by gently lifting it upward until the hook catches on both sides clear the locating slots. Then pull door out to remove.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Figure 1
Operation of millivolt and electronic gas con- trol 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 appli- ances refer to the detailed lighting instructions found on Pages 16 & 17 . 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 appli- ance front glass enclosure panel (see Figure 1 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.
