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