PSE Pilot
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
F584-703
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.
