Thin white deposits on the igniter are typical, but brown or

black deposits could be the result of ﬂue gas recirculation. Thoroughly

inspect the venting system and termination for the possibility of leakage

or ﬂue gas feedback into the air line.

Dirty burner and/or heat exchanger will cause high back pressure and

poor ignition.

Follow procedure in maintenance section of this manual to clean burner

and heat exchanger. Visual inspection of ﬂueways may not be suﬃcient

to diagnose condition.

Check combustion settings on high and low ﬁre and adjust per setup

instructions if necessary.

Check incoming gas pressure with boiler oﬀ and at high ﬁre. Adjust

within limits on rating label.

Verify correct boiler model is selected in control and high altitude is

selected for installations 5,500 feet above sea level.

Check ignition cable resistance. Should measure 1000 Ohms (+/- 50

Ohms).

Check for ﬂue pipe and intake pipe restrictions or blockage.

Check burner fasteners and gaskets.

Check venturi gaskets and proper propane oriﬁce bushing.
