Start-up sequence runs but
burner does not light.
The low fire flame is weak or
unstable.
Eclipse RatioMatic Burners, RM Series, V5, Installation Guide 110, 12/3/2014
Possible Cause
No ignition: There is no power to the ignition
transformer.
No ignition: Open circuit between the
ignition transformer and the igniter.
No ignition: The igniter needs cleaning.
No ignition: The igniter is not correctly
grounded to the burner.
No ignition: Igniter insulation is broken.
Igniter is grounding out.
Not enough gas: The gas pressure going
into the ratio regulator (RM0050-RM0700)
or pilot regulator (RM1000-RM3000) is too
low.
Not enough gas: The impulse line to the
ratio regulator is leaking.
Not enough gas: The pilot adjusting valve or
bypass valve is not open far enough.
Not enough gas: Start gas solenoid valve
does not open.
Not enough gas: Gas valve does not open.
Not enough gas: Ratio regulator is
incorrectly set.
No flame signal: Broken flamerod or dirty
UV scanner lens.
No flame signal: Spark plug and flamerod
reversed.
Too much gas: Wrong or missing burner
fuel orifice.
Not enough gas flowing to the burner.
Not enough air.
Flamerod is directly beneath the
combustion air inlet.
Solution
Restore the power to the ignition
transformer.
Repair or replace the wiring of the igniter.
Clean the igniter.
Clean the threads on the igniter and the
burner.
NOTE: Do not apply grease to the threads
on the igniter.
Inspect the igniter, replace if broken.
Check the start-up settings. Measure the
gas pressures and adjust where necessary.
Repair any leaks.
Adjust bypass or low fire gas.
Check the solenoid valve coil for proper
operation. Replace it if necessary.
Check the wiring to the automatic gas shut-
off valve.
Check the output from the flame safeguard.
Open manual gas cock.
Adjust the ratio regulator to the proper
setting.
Inspect and clean sensor. Replace if
necessary.
Exchange spark plug / flamerod or their
wiring.
Check RatioMatic Datasheets, Series 110
for fuel orifice and given fuel.
Adjust the ratio regulator to increase the
gas flow.
Check for proper blower rotation.
Check air filter for blockage.
Compensate for chamber by opening the
low fire air butterfly valve position.
Swap the flamerod with the spark rod so
that the flamerod is 180° from the
combustion air inlet.
