SECTION Q: MAINTENANCE
SUGGESTED MINIMUM MAINTENANCE SCHEDULE:
Regular service by a qualified service agency and maintenance must be performed to assure maximum boiler 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 function, deterioration or leakage.
4.
Check that boiler 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 boiler.
6.
Follow pre-start-up check in Section N.
7.
Visually inspect burner flame. Should see light blue flame. Visually inspect hot surface ignitor for damage, cracking
or debris build-up.
8.
Check operation of safety devices. Refer to manufacturer’s instructions.
9.
Follow oil-lubricating instructions on circulator. 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.
Daily:
1.
Check that boiler 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 boiler.
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 function, deterioration or leakage.
4.
Check air vents for leakage.
Periodically:
1.
Check relief valve. Refer to manufacturer’s instructions on valve.
2.
Test low water cutoff, if used. Refer to manufacturer’s instructions.
3.
Clean screen and air filter in intake.
