9. MAINTENANCE

9.1. Suggested Minimum

Maintenance Schedule

Regular service by a qualified service agency and

maintenance must be performed to ensure maximum

operating efficiency.
Daily and monthly maintenance as outlined below may be

performed by onsite maintenance staff.

9.1.1. 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.

9.1.2. 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 venting system for proper function,

deterioration or leakage.

3. Visually inspect for proper operation of the

condensate drain in the venting. If leaks are observed

repair at once.

4. Check air vents for leakage.

9.1.3. Yearly (Beginning of each Heating

Season)

Schedule annual service 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 directed to appropriate condensate treatment

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 air filter and replace as necessary.
5.  Follow pre-start-up check in the Start-up section.
6.  Check flame strength signal as noted on display

Remove and visually inspect hot surface igniter and

sensor for damage, cracking or debris build-up.

7. Check operation of safety devices. Refer to

manufacturer’s instructions.
