MAINTENANCE
PILOT ADJUSTMENT
1.
Locate the pilot adjustment screw on
the valve.
2.
The pilot flame should surround at
least the top 3/8” of the powerpile
(pilot generator)
or flame sensor
(see
Figure 8).
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).
MANUAL RESET SWITCH
For your safety this furnace is equipped
with a manual reset limit switch. In case
of failure by the primary limit switch, this
switch will shut the valve down completely
before unsafe temperatures are reached.
After a cool down period, switch must be
manually reset. If outages persist, call a
qualified service person.
TO DECREASE
THE PILOT FLAME
Turn the screw clockwise.
(Approximately six full turns to bottom of pilot
light channel)
until you produce a sufficient
flame at the minimum noise level.
For proper and safe operation, keep furnace and furnace area clean. At regular intervals turn
control valve off, let cool and clean inside control compartment. To clean cabinet, use only
a damp cloth. Do not use any kind of solvent or cleaning fluid that could leave a residue or
invisible coating that would burn or give off fumes when furnace is turned on.
Have the furnace checked, cleaned, and repaired by a qualified service technician, including
the vent system, pilot and burner operation prior to use each year.
The bearings of the fan motor should be oiled every twelve (12) months with S.A.E. 20 oil.
(See Figure 7).
Follow a regular service and maintenance schedule for safe and efficient operation.
Examine the venting system as a routine part of the safety performance check on an
annual basis.
