Possible Cause
Not enough gas pressure into the ratio
regulator.
Loading line to the ratio regulator is leaking. Repair the leak in the loading line.
Pilot set too lean, becoming unstable as air
increases.
Main gas adjusting valve not open enough. Increase valve opening.
Suction or back pressure in chamber
fluctuates, upsetting pilot stability.
Internal damage to the burner: Some parts
inside the burner are loose, dirty, or burned
out.
The air/gas ratio is out of adjustment.
Air filter is blocked.
Gas pressure going into the ratio regulator
is too low.
Air pressure switch has not made contact.
High gas pressure switch has activated.
Low gas pressure switch has activated.
Malfunction of the flame safeguard system
(e.g. shorted out flame sensor or electrical
noise in the sensor line).
No power to the control unit.
Main power is off.
Gas flame is too high.
Gas flow is too low.
Too much gas flow.
Check the start-up settings.
Measure the gas pressures and adjust
them where necessary.
Check for valve train pressure loss.
Increase pressure into the pilot regulator.
Cross-connect pilot regulator vent to the
combustion chamber, but not via the burner
air pressure tap.
Contact Eclipse for further information.
Measure all the gas pressures and air
pressures. Compare these pressures to the
documented initial start-up settings and
adjust them where necessary.
Clean or replace the air filter.
Adjust the gas pressure.
Check air pressure switch adjustment.
Check air filter.
Check blower rotation.
Check outlet pressure from blower.
Check incoming gas pressure.
Adjust gas pressure if necessary.
Check pressure switch setting and
operation.
Check incoming gas pressure.
Adjust gas pressure if necessary.
Check pressure switch setting and
operation.
Have a qualified electrician troubleshoot
and correct the problem.

Be sure the main power to the system is
switched to the "on" position.
Gas butterfly valve is open too far or main
gas regulator spring is screwed in too far.
Gas butterfly valve is closed too far, or main
gas regulator spring is screwed out too far.
Main gas proportionator spring is set for too
much flow, or pilot gas cock adjustment is
open too far.
Insufficient air flow due to dirty blow filter or
impeller.
