Verify that the vent is not obstructed. Check for and
remove any obstruction to the flow of combustion or
ventilation air to the heater.
6
Venting must be pitched towards the boiler to allow
condensate to drain
7
Ensure that condensate drains are inspected and
ensure that condensate is being directed to appropriate
condensate management system or drain, as required by
local codes.
8
Check operation of safety devices.
9
Check fan and fan motor.
10
Check if there is any flue leakage from the heat exchanger
flue outlet and exhaust vent connection. In case of leak
detection replace the related gaskets (1).
11
Remove the burner door (8), check that combustion
chamber is free of deposits and proceed to clean.
12
Check the burner door insulation panel (6), gasket (4) and
high temperature glass braided rope (5) for deterioration,
and if they are worn, replace them.
13
Check the combustion chamber insulation panel (3)and,
if it is worn, replace it.
14
Check the condition of the burner (7), ensure that it is not
loose; clean if necessary.
15
Verify spark and check the flame ignition electrode (12) for
deterioration and, if it is worn, replace it.
If the electrode is removed from its seat, its gasket (11)
must be replaced.
16
Check the flame sensor electrode (10) for deterioration
and, at the slightest sign of deterioration, replace it. If
the sensor is removed from its seat, its gasket (9) must
be replaced.
17
Check the boiler condensate trap, remove and clean if
needed – re-prime trap.
18
Check that the condensate check valve is working
correctly.
19
Cleaning of the filters is required.
20
Check for piping leaks around pumps, relief valves and
other fittings. Repair, if found. DO NOT use petroleum-
based stopleak.
21
Inspection of the low water cutoffs in the boiler and
system. Also it needs to specify that float type low water
cutoffs must be periodically flushed.
22
Check the correct working of the relief valve.
Refer to
manufacturer’s instructions
on the valve.
23
Visually inspect the burner flame and ignition sequence
to ensure proper operation.
