MAINTENANCE
Suggested Minimum
Maintenance Schedule:
Regular service by a qualified service agency and
maintenance must be performed to ensure maximum
heater operating efficiency. Maintenance as outlined
below may be performed by the owner.
Yearly (Beginning of each heating
season):
1. Annual service call by qualified service agency.
2. Visually check top of vent for soot. Call service
person to clean. Some sediment at bottom of vent
is normal.
3. Visually inspect venting system for proper func-
tion, deterioration or leakage.
4. Check that heater area is free from combustible
materials, gasoline, and other flammable vapors
and liquids.
5. Check for and remove any obstruction to the flow
of combustion or ventilation air to heater.
6. Follow pre-start-up check in the Initial Start-up
section.
7. Visually inspect burner flame. Should see light
blue flame. Visually inspect hot surface igniter for
damage, cracking or debris build-up.
8. Check operation of safety devices. Refer to manu-
facturer’s instructions.
9. Follow oil-lubricating instructions on circulator (if
required). Over-oiling will damage circulator.
Water-lubricated circulators do not need oiling.

HANDS ON OR GRASP PIPES. Use a light touch
- return piping will heat up quickly.
11. Check blower and blower motor. Clean and oil as
necessary.

valves and other fittings. Repair, if found. DO NOT
use petroleum based stop leak.
