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 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.

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.

3.Check that area is free from combustible materi- als, 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 the Start-up section.

6.Visually inspect burner flame. It should be light blue. Remove and visually inspect hot surface ig- niter 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 circulator if required. Over-oiling will damage circulator. 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 circulators, relief valves and other fittings. Repair, if found. DO NOT use petroleum-based stop-leak.

12.Clean air filter.

Periodically

1.Check relief valve. Refer to manufacturer’s in- structions on valve.

2.Test low water cut-off, if used. Refer to manufac- turer’s instructions.

3.Clean screen and air filter in intake.

Preventive Maintenance Schedule

The following is required procedure in CSD-1 states and good practice for all Hi Delta installations.

Daily

1.Check gauges, monitors and indicators.

2.Check instrument and equipment settings. (See “Post Start-Up Check” on page 53.)

3.Check burner flame. (Should see light blue flame).
