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.
