Solution
Restart the GasTrac while watch-
ing through the sight glass. If you
don't see a spark during the 4-
second ignition period:
Verify there is power supplied
to the transformer during the
ignition period.
Check the wire and connec-
tions between the transformer
and spark igniter.
Check the spark igniter.
Replace if damaged.
If the burner fails to light even
though you can see a spark:
Verify that the gas supply is
on and that the gas shutoff
valves are open during the
ignition period.
Restart the GasTrac 4 or 5
times to purge any air that may
be in the gas lines.
Verify that the gas pressure
regulator is set to supply the
correct pressure.
If the burner ignites and then
goes out, check
Clean if necessary.
Verify that the static pressure of
the combustion exhaust flue is 1
to 2 inches of water column. If
not, you may need to add a draft
fan to the flue to create the cor-
rect static pressure.
If none of the solutions above can
resolve the problem, you may
need to replace the burner con-
troller.
