Burner Lava Rock Placement

XDV Direct Vent Gas Fireplace

Burner Lava Rock Placement

Place the contents of the small bag of ceramic burner lava embers on the burner in front of the front logs. Do not place burner lava rock in the inside corners of the front logs.

Large Lava Rock

The large bag of lava rock provided with this fireplace must be placed on the firebox base around the sides of the burner assembly and on the tray beneath the grate.

Under no circumstances should this large lava rock be placed on any part of the burner assembly.

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. 65 or 66)

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.

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. 67)
