CAUTION

WATER LEAKS CAN CAUSE SEVERE CORROSION DAMAGE TO THE BOILER OR OTHER SYSTEM

COMPONENTS. REPAIR ANY LEAKS FOUND IMMEDIATELY.

IMPORTANT

• CLEAN THE BOILER EVEN IF THERE ARE NO SIGNIFICANT SOOT DEPOSITS. FAILURE TO

REMOVE ALL SULFUR AND ASH DEPOSITS ANNUALLY CAN CAUSE SEVERE CORROSION

DAMAGE.

• WHEN CLEANING THE REAR FLUE PASSAGE, BE CAREFUL NOT TO PUSH THE BRUSH TOO

FAR BEYOND THE BOTTOM OF THE PINS. DOING SO MAY DAMAGE THE TARGET WALL.

a) Make sure that the vent system is free of obstructions and soot.

b) Make sure that all vent system supports are intact.

d) Inspect venting components for corrosion or other deterioration. Replace any defective vent system components.

4) Service the oil burner:

a) Replace oil nozzle with identical make and model (see Table 3).

b) Inspect the electrodes. Replace if they are deteriorated. Make sure that the electrode position is set according to the

burner manufacturer’s instructions.

c) Remove and clean fuel pump strainer.

d) Remove any accumulations of dust, hair, etc. from the air shutter, blower wheel, and other air handling parts of the

burner.

5) Replace the fuel oil line filter element and gaskets.

6) Inspect all oil piping and fittings for kinks and leaks. Repair any found.

7) Inspect the hydronic piping, tankless coil gasket, and boiler plugs for water leaks. Repair any leaks found immediately.

8) Verify operation of relief valve by manually lifting lever; replace relief valve immediately if valve fails to relieve pressure.

9) Open fuel line shut-off valve(s) and restore electrical power to the boiler.

burner adjustments using instruments. Check for proper operation of all controls.
