Possible Cause
There is no power to the ignition
transformer.
Open circuit between the ignition
transformer and the spark rod.
The spark rod needs cleaning.
The spark rod is not correctly grounded
to the burner.
The spark rod is grounded to the
nozzle or the air shroud.
The spark rod and flame rod wiring is
reversed.
There is air in the gas line.
The gas pressure into the ratio
regulator is too low.
The impulse line to the ratio regulator is
leaking.
Start gas solenoid valve does not open
(if fitted).
Manual gas valve closed.
Manual gas cock not open.
Gas pressure out of ratio regulator is
too high.
Incorrect type of flame safety, must
have ignition during all the trial for
ignition.
Wrong type of ignition transformer.
Improper air/gas settings.
Flame rod or UV scanner needs
cleaning.
Flame rod is grounded to nozzle.
Flame rod and spark rod reversed.
Air in the gas line.
Ratio regulator incorrectly set.
Not enough air.
Solution
Restore the power to the ignition
transformer.
Repair or replace the wiring to the
spark rod.
Clean the spark rod.
Clean the threads of the spark rod and
the burner. Do not use pipe sealant on
ignition plug threads.
Check the spark rod position.
Correct wiring.
Repeat the start attempt several times.
Measure the gas pressure into the ratio
regulator and adjust gas pressure if
necessary. (See "Adjustment, Start &
Stop" section)
Repair any leaks.
Check wiring to the valve. Check
output from the flame safeguard.
Check solenoid valve coil for proper
operation. Replace if necessary.
Open the gas valve.
Open the manual gas cock.
Check adjustments. If necessary,
remove regulator and investigate.
Change flame monitoring equipment.
Use correct type.
Check pressure and settings and
adjust as necessary.
Clean the flame rod or UV scanner
lens.
Adjust position so ceramic insulation
contacts nozzle.
Reposition spark rod or flame rod.
Repeat start-up several times.
Adjust to proper setting.
Readjust gas flow at ratio regulator.
Open automatic valve slightly.
