8, 10

Check that there are no sagging sections along the venting horizontal runs.

Check the tubes connecting the air differential pressure switches with the air chamber

tightly.

Check externally the vent system for soot, rust scale or corrosion. Check for

dislodged venting or possible leaks in venting ducts and boiler.

Check to insure that the condensate trap is filled with water, but not plugged.

Visually inspect main burners to ensure proper flame operating characteristics and

ignition/extinction is ok.

Check burner operation to hear that they do not make unusual audible sounds

when boiler is on.

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 a

low area in the event of a leak.

Visually inspect for leaks in the water piping and at water piping connections.

Circulating pumps used with hot water heating systems should be inspected for

water leaks.

Check for weeping at pressure relief valve outlet during normal operation.

Listen for unusual audible sounds in the boiler.

Read temperature and pressure gauge. Check with qualified installer or service

agency to determine acceptable temperature and pressure range for your heating

system.

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:

Have a qualified service technician remove the draft hood from the boiler and inspect the flue ways 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.

Have a qualified service technician inspect the pilot burner and main burner.

The qualified service technician should follow the "Maintenance Checklist" and other applicable safety

information found in the Installation and Service Manual.
