WARNING
The boiler must be connected to an approved chimney in good condition. Serious property
damage could result if the boiler is connected to a dirty or inadequate chimney. The interior
of the chimney flue must be inspected and cleaned before the start of the heating season and
should be inspected periodically throughout the heating season for any obstructions. A clean
and unobstructed chimney flue is necessary to allow noxious fumes that could cause injury or
loss of life to vent safely and will contribute toward maintaining the boiler’s efficiency.
3) Inspect the vent system:
a) Make sure that the vent system is free of obstructions and soot.
b) Make sure that all vent system supports are intact.
c) Inspect joints for signs of condensate or flue gas leakage.
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 11.1).
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.
e) 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 and boiler 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.
10) Fire the boiler and check it out using the procedure outlined in “Start-up and Checkout” . This must include checking the
burner adjustments using instruments. Check for proper operation of all controls.

Water leaks can cause severe corrosion damage to the boiler or other system components.
Repair any leaks found immediately.
