The majority of the complaints associated with the operation of the will likely be a direct result of improper venting. If the customer complains of smelling burnt gas around the water heater, first check for vent gases that may be leaking from the PVC joints or around the area between the blower assembly and water heater. Seal all leaks with the high temperature silicone sealant provided.

Check for restrictions in the venting that may cause some spillage of burnt gas into the room and check your draft, visually inspecting the vent termination for blockage, clearing blockage as

necessary.

Improper venting is also a major cause of sooting in water heaters. If you experience sooting with the POWER SHO~, check that the inlet air damper swings freely and opens 1 1/4" when the blower is running.

If water is dripping from the blower, condensate is the culprit To correct the problem, install a condensate tee, and pipe to drain.

If the customer complains of nuisance pilot outage or pilot gas odor on standby, this may be due to a lack of combustion air, or other appliance (exhaust fans, clothes dryers, etc.) creating a backdratt in the FPS venting. In either case, install additional make-up air ducts.
