Flame & Temperature Adjustment
For fireplaces equipped with Hi/Lo valves, flame adjust-
ment is accomplished by rotating the Hi/Lo adjustment
knob located near the centre of the gas control. (Fig. 64
or 65)
Manual ON/OFF Valve
The Manual ON/OFF valve was designed particularly
for the main burner operation. The main burner flame
can be turned on and off as desired. This valve is rec-
ommended to be set to the “ON” position when lighting
the unit. (Fig. 66)
Flame Characteristics
It is important to periodically perform a visual check of
the pilot and the burner flames. Compare them to Fig-
ures 67-68. If any of the flames appear abnormal call a
service person.

Inspecting the Venting System
This appliance venting system is designed and con-
structed to develop a positive flow adequate to remove
flue gases to the outside atmosphere.
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of flue gases.
To inspect the venting system, make sure the main gas
valve is off. Remove window frame assembly (Refer to
Window Frame Assembly Removal Section). Using a
flashlight, check the area above the baffle in the com-
bustion dome. Clean if necessary.
