Inspecting the Venting System
This appliance venting system is designed and
constructed 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 the window frame assembly.
(Refer to Window Frame Assembly Removal section.)
Using a flashlight, check the area above the baffle in
the combustion dome. Clean if necessary.
