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

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

Glass Cleaning

It will be necessary to clean the glass periodically. During start-up it is normal for condensation to form on the inside of the glass. This can cause lint, dustandotherairborneparticlestoclingtotheglass surface.Alsoinitialpaintcuringmaydepositaslight

Refer to Figure 1 for access to the gas control valve. Millivolt appliances will be fitted with the gas control valve shown in Figure 2. Appliances with electronic systems will be fitted with the electronic valve shown in Figure 3. Familiarize yourself with the gas control valve that your appliance uses.

Millivolt Appliances -

To light millivolt appliances refer to the detailed lighting instructions found on page 12 (English) and page 13 (French). Millivolt appliance lighting instructions may also be found on the pull out lighting instruction labels attached to the gas control valve.

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 be- tween fixed low and high settings 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). (An extension is attached to this knob so that the adjustment may be made at the modesty panel.)

film on the glass. It is therefore recommended that the glass be cleaned two or three times with a non- ammoniahouseholdcleanerandwarmwater(agas fireplace glass cleaner is recommended).

After that the glass should be cleaned two or three times during each heating season, depending on the circumstances present.

Note: Clean glass after first two weeks of operation.

WARNING: DO NOT USE ABRASIVE CLEANERS. NEVER CLEAN THE GLASS WHEN IT IS HOT.

CAUTION: DO NOT TOUCH THE FRONT ENCLOSURE GLASS WITH YOUR HANDS WHILE

Millivolt appliances are fitted with a burner ON/OFF control switch (rocker switch). See Figure 1 on page 3 for its location. Once the pilot is lit, the ON/OFF rocker switch will control the appliance ON/OFF operation. To oper- ate: Toggle the switch between its ON and OFF positions. If your millivolt appliance is equipped with an optional wall-mounted ON/OFF switch or remote control kit and the pilot is lit, the appliance main burner may be turned on and off with the wall switch or remote control.

Electronic Appliances -

To light electronic appliances refer to the detailed lighting instructions found in both En- glish and French on pages 14 and 15 of these instructions respectively. Electronic appliance lighting instructions may also be found on the pull out lighting instruction labels attached to the gas control valve.

Electronic appliances are fitted with a ON/OFF burner control switch (rocker switch). See Figure 1 on page 3 for its location. The electronic system will go through the whole lighting sequence automatically once the rocker switch is toggled to the ON position. If your electronic appliance is equipped with an optional wall-mounted ON/OFF switch or remote control kit the appliance main burner may be turned on and off with the wall switch or remote control.

2.When lit for the first time, this appliance will emit a slight odor for 14 hours. 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 materi- als, etc. It is important that control compart- ments, burners and circulating air passage- ways of the appliance be kept clean and clear of obstruction of venting and combustion air.

4.Always turn off gas to the pilot (millivolt appli- ances) and let the unit cool down before cleaning. Before re-lighting, refer to the lighting instruc- tions in this manual. Lighting instructions may also be found on the pull out lighting instruction labels attached to the gas control valve.
