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.
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 intake screen and air filter.
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 replace hot surface ig-niter and
sensor.
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.
13. Conduct a combustion test at full fire. Carbon di-
oxide should be 8.2% ± 0.5% at full fire for natural
gas, and 9.4% ± 0.5% for propane gas; Carbon
monoxide should be < 150 ppm).
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 54.)
3. Check burner flame. (Should see light blue flame).
