WARNING! Do not install screens over the vent for any reason. Screens
will become restricted and cause unsafe furnace operation. Accessories
are being marketed for RV products which we do not recommend. For
your safety, only factory authorized parts are to be used on your furnace.
2. Periodically inspect the vent for obstructions or presence of soot. Soot is
formed whenever combustion is incomplete. This is your visual warning that the
furnace is operating in an unsafe manner. If soot is present, immediately shut
furnace down and contact your dealer or a qualified service person.
3.
Periodically observe the main burner flame to assure it is burning with a hard
blue flame with well defined burner ports (See Figure 2). If flame appears yellow
or burner has a lazy flame, shut furnace down. It is possible that burner needs
cleaning or replaced. To Inspect the main burner, remove the four (4) screws (A.
8. C and D) securing the burner access door to the combustion chamber (See
Figure 1) If excessive rust and corrosion are present on burner surface, the
burner must be thoroughly cleaned or replaced. The burner may be cleaned using
a steel wire brush and blown clean using high compression air. Contact a qualified
service person for assistance.
NOTE: To observe flame, cabinet front must be removed. Operation of burner can
then be observed through the viewing window on front of chamber (See Figure 1).
4. Keep furnace clean. More frequent cleaning may be required due to excessive
lint from carpeting, bedding material, etc. It is imperative that control
compartments, burners and circulating air passageways of the appl~ance be kepi
