MAINTENANCE

Suggested Minimum

Maintenance Schedule

Regular service by a qualified service agency and maintenance 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 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 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 func- tion, deterioration or leakage.

4.Visually inspect for proper operation of the con- densate 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 func- tion, deterioration or leakage. Ensure that condensate drain is inspected and ensure that condensate is being directed to appropriate con- densate management system or drain, as required

by local codes.

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

4.Check air filter and replace as necessary.

5.Follow pre-start-up check in the Start-up section.

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 manu- facturers’ 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.

11.Check for piping leaks around pumps, relief valves and other fittings. Repair, if found. DO NOT use petroleum-based stop-leak.

Periodically

1.Check relief valve. Refer to manufacturer’s instructions on valve.

2.Test low water cut-off (if equipped). Refer to manu- facturer’s instructions.

Preventive Maintenance Schedule

The following procedures are recommended and are good practice for all MVB installations.

Daily

1.Check gauges, monitors and indicators.

2.Check instrument and equipment settings. (See “Post Start-Up Check” on page 45.)

3.Check burner flame. (Should see light blue flame at full input rate).
