CHECKLIST
ο
Check air openings are not restricted and will not be blocked off. Adequate supply air is
necessary for combustion, flue gas dilution and ventilation.
ο
When the boiler has operated for several minutes, check for spillage at draft hood, venting
ducts, and other areas susceptible to spillage.
ο
Check externally the draft hood and vent system for soot, rust scale or corrosion. Check for
dislodged venting or possible leaks in venting ducts.
ο
Visually inspect main burners and pilot to ensure proper flame operating characteristics and
ignition/extinction is ok.
ο
Visually check burners to see that they are not cracked or dislodged.
ο
Check that gas piping is secured. Smell for gas leaks around boiler and gas piping
connections. Gas leaks can also be checked for using a soap solution; do not use an open
flame to check for leaks. Note: Propane is heavier than air and pools in low areas in the event
of a leak.
ο
Visually inspect for leaks in the water piping and at water piping connections.
ο
Circulating pumps used with hot water heating systems should be inspected for water leaks.
ο
Check for weeping at pressure relief valve outlet during normal operation.
ο
Listen for unusual audible sounds in the boiler.
ο
Read temperature and pressure gauge. Check with qualified installer or service agency to
determine acceptable temperature and pressure range for your heating system.
ο
Combustible materials, gasoline and other flammable vapors and liquids should not be stored
in the area of the boiler.
If any problems are identified during your inspection, contact a qualified service agency for
corrective measures.
Once every year
at the beginning of the heating season:
ο
Have a qualified service technician remove the draft hood from the boiler and inspect the
flueways for the presence of soot or rust scale. The draft hood and smoke pipe connecting the
draft hood to the flue must be inspected for rust or corrosion before replacing the draft hood. The
presence of soot, rust scale or corrosion indicates misadjustment.
ο
Have a qualified service technician inspect the pilot burner and main burner.
ο
The qualified service technician should follow the "Maintenance Checklist" and other applicable
safety information found in the
Installation and Service Manual
.
