MAINTENANCE INSTRUCTIONS

1. Installation and repair must be done by a qualified
service person. The appliance should be inspected
before use and at least annually by a professional
service person. More frequent cleaning may be required
due to excessive lint from carpeting, bedding material,
etc. It is imperative that control compartments, burners,
pilot burners, circulating air passageways and venting
systems of the appliance be kept clean.
2. If the appliance has been equipped with the optional
WFF81-C fan kit assembly, the bearings of the motor
should be oiled every six months with approximately 2
drops of S.A.E. 20 oil.
3. The appliance area must be kept clear and free of any
combustible materials, gasoline and other flammable
vapors and liquids.
4. It is essential that the flow of combustion and ventilation
air not be obstructed.
5. Periodic examination of the entire ventilation system
as a routine part of the safety performance check is
recommended on an annual basis.

PILOT ADJUSTMENT

Locate the pilot adjustment screw on the valve. The pilot
flame should surround at least the top 3/8" of the powerpile
(pilot generator) or thermocouple (see below). The pilot is
unregulated so it will be operating at inlet line pressure (Max.
7" w.c. for natural gas and 11" w.c. for propane). To decrease
the pilot flame, turn the screw clockwise (approximately
seven to nine full turns to bottom of pilot light channel) until
you produce sufficient flame at the minimum noise level.
