SECTION G

Maintenance

Suggested Minimum

Maintenance Schedule

Regular service by a qualified service agency and mainte- nance must be performed to ensure maximum operating efficiency.

Maintenance as outlined below may be performed by the owner.

Daily

1.Check that the area where the heater is installed is free from combustible materials, gasoline, and other flam- mable 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 pumps, 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.Visually inspect for proper operation of the condensate drain in the venting. If leaks are observed repair at once.

5.Check air vents for leakage.

Yearly (Beginning Of Each Heating Season)

Schedule annual service call by qualified service agency.

1.Visually check top of vent for soot. Call service person to clean. Some sediment at bottom of vent is normal.

2.Visually inspect venting system for proper function, deterioration or leakage. Ensure that condensate drain is inspected and ensure that condensate is being di- rected to appropriate condensate management system or drain, as required by local codes.

3.Check that area is free from combustible materials, gasoline, and other flammable vapors and liquids.

4.Check for and remove any obstruction to the flow of combustion or ventilation air to heater.

5.Follow pre-start-up check in Section D.

6.Visually inspect burner flame. It should be light blue at full input. Remove and visually inspect hot surface igniter and sensor for damage, cracking or debris build-up.

7.Check operation of safety devices. Refer to manufac- turers’ instructions.

8.Follow oil-lubricating instructions on pump (if re- quired). Over-oiling will damage pump. Water-lubricated circulators do not need oiling.

9.To avoid potential of severe burn, DO NOT REST HANDS ON OR GRASP PIPES. Use a light touch; return piping will heat up quickly.

10.Check blower and blower motor.
