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.
MAINTENANCE INSTRUCTION
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 10).
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.
