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.
10. To avoid potential of severe burn, DO NOT REST
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.
12. Check for piping leaks around circulators, relief
valves and other fittings. Repair, if found. DO NOT
use petroleum based stop leak.
13. Check air filter and replace if necessary.
Daily:
1. Check that heater area is free from combustible
materials, gasoline, and other flammable vapors
and liquids.
2. Check for and remove any obstruction to the flow
of combustion or ventilation air to heater.
Monthly:
1. Check for piping leaks around circulators, mixing
valves, relief valves, and other fittings. If found,
repair at once. DO NOT use petroleum-based stop
leak compounds.
2. Visually inspect burner flame.
3. Visually inspect venting system for proper func-
tion, deterioration or leakage.
4. Check air vents for leakage.
Quarterly:
1. Check relief valve. Refer to manufacturer’s
instructions on valve.
2. Test low water cut-off, if used. Refer to manufac-
turer’s instructions.
3. Check the air filter; replace if necessary.
7. Carefully lift and remove the flue collector.
8. Lift heat exchanger straight up being careful not to
damage the refractory.
9. Reverse the above procedure to re-install. Make
sure sufficient high temperature silicone sealant
(RTV) is placed along the vertical sides of the tube
sheet and flue collector.
