WARNING
Tb avoid personal injury, death or
property damage, keep boiler area
clear and free from combustible ma¬
terials, gasoline and other flammable
vapors and liquids.
Do not block flow of air to boiler. In¬

system life.
Suggested Minimum Maintenance Schedule for
Qualified Service Technician Only
Beginning of each heating season:
1. Annual service call by a qualified service agency.
2. Check burners and flueways and clean if necessary. Ref¬
erence "Clean Boiler Heating Surfaces" and "Cleaning
Main Burners," page 15.
3. Visually inspect base insulation. Reference "Inspect Base
Insulation," page 11.
4. Follow procedure "1b Place in Operation," page 11.
5. Visually inspect pilot and burner flames. Reference
"Check Burner Flames," pages 11 and 12.
6. Visually inspect venting system for blockage, deteriora¬
tion or leakage. Reference "Inspect Venting System,"
page 12.
7. Check operation of low-water cut-off, if used, and addi¬
tional field-installed controls. Refer to manufacturer's in¬
structions.

1. Check for leaks in boiler and piping. If found, repair at
WARNING
DANGER
Leaks must be repaired at once.
Failure to do so can damage
boiler, resulting in substantial
property damage.
Do not use petroleum based
cleaning or sealing compounds in
boiler system. Severe damage to
boiler will result, causing sub¬
stantial property damage.
2. Visually inspect pilot and burner flames. Reference
"Check Burner Flames," pages 11 and 12.
3. Visually inspect venting system for blockage, deteriora¬
tion or leakage. Reference "Inspect Venting System,"
page 12.
4. Check automatic air vent for leakage. If leaking, remove
vent cap and push valve core in to wash off sediment that
may have accumulated on valve seat. Release valve,
replace cap and open one turn.
End of each heating season:
1. Follow "Annual Shutdown Procedure," page 15.
