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)
