Troubleshooting
Problem Possible Cause Solution
Start-up sequence runs but
burner does not light.
No ignition: There is no power to the ignition
transformer.
Restore the power to the ignition
transformer.
No ignition: Open circuit between the
ignition transformer and the igniter.
Repair or replace the wiring of the igniter.
No ignition: The igniter needs cleaning. Clean the igniter.
No ignition: The igniter is not correctly
grounded to the burner.
Clean the threads on the igniter and the
burner.
NOTE: Do not apply grease to the threads
on the igniter.
No ignition: Igniter insulation is broken.
Igniter is grounding out.
Inspect the igniter, replace if broken.
Not enough gas: The gas pressure going
into the ratio regulator (RM0050-RM0700)
or pilot regulator (RM1000-RM3000) is too
low.
Check the start-up settings. Measure the
gas pressures and adjust where necessary.
Not enough gas: The impulse line to the
ratio regulator is leaking.
Repair any leaks.
Not enough gas: The pilot adjusting valve or
bypass valve is not open far enough.
Adjust bypass or low fire gas.
Not enough gas: Start gas solenoid valve
does not open.
Check the solenoid valve coil for proper
operation. Replace it if necessary.
Not enough gas: Gas valve does not open.
Check the wiring to the automatic gas shut-
off valve.
Check the output from the flame safeguard.
Open manual gas cock.
Not enough gas: Ratio regulator is
incorrectly set.
Adjust the ratio regulator to the proper
setting.
No flame signal: Broken flamerod or dirty
UV scanner lens.
Inspect and clean sensor. Replace if
necessary.
No flame signal: Spark plug and flamerod
reversed.
Exchange spark plug / flamerod or their
wiring.
Too much gas: Wrong or missing burner
fuel orifice.
Check RatioMatic Datasheets, Series 110
for fuel orifice and given fuel.
The low fire flame is weak or
unstable.
Not enough gas flowing to the burner.
Adjust the ratio regulator to increase the
gas flow.
Not enough air.
Check for proper blower rotation.
Check air filter for blockage.
Compensate for chamber by opening the
low fire air butterfly valve position.
Flamerod is directly beneath the
combustion air inlet.
Swap the flamerod with the spark rod so
that the flamerod is 180° from the
combustion air inlet.
