This appliance venting system is designed and
constructed to develop a positive flow adequate to
remove flow 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.
Inspecting the Venting System
It is important to periodically perform a visual check of
the pilot and burner flames. Compare them to the
pictorials illustrated below (Fig. 43 and Fig. 44). If the
flame patterns appear abnormal, contact a qualified
service provider for service and adjustment.
