? Problem
! Possible Cause
• Solution
? start-up sequence runs but burner does not light.
! No ignition: There is no power to the ignition transformer.
• Restore power to the ignition transformer.
! No ignition: Open circuit between the ignition transformer and
the igniter.
• Repair or replace the wiring to 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 of the igniter and the burner.
note: Do not apply grease to the thread of the igniter.
! No ignition. Igniter insulator is broken. Igniter is grounding out.
• Inspect the igniter. Replace if broken.
! Igniter grounds out, igniter is bent.
• Inspect ignitor by removing nozzle and rear cover. Check if
gaps exist, readjust if needed.
! Not enough gas. The gas pressure into the ratio regulator is too
low.
• Check the start-up setting. Measure the gas pressures and
adjust where necessary.
! Not enough gas. The impulse line to the ratio regulator is leak-
ing.
• Repair any leaks.
! Not enough gas. The adjustable orifice 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 shutoff 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 flame rod and/or dirty UV scanner
lens.
• Inspect and clean sensor. Replace if necessary.
! Too much gas. Gas butterfly valve too far open.
• Check for proper setting.
? the low fire flame is weak or unstable.
! Not enough gas flowing to the burner.
• Adjust the ratio regulator or bypass fuel adjustable orifice
valve to increase the gas flow.
! Not enough air.
• Check for proper blower rotation. Check air filter for block-
age. Compensate for chamber by opening the low fire air
butterfly valve position.
? the burner goes out when it cycles to high fire.
! Not enough gas pressure into the ratio regulator.
• Check the start-up settings. Measure the gas pressures and
adjust them where necessary. Check for valve train pressure
loss.
! Loading line to the ratio regulator is leaking.
• Repair the leak in the loading line.
! Not enough gas flowing to the burner.
• Adjust the ratio regulator to increase the gas flow.
! Fuel bypass line is not set correctly.
• Set fuel bypass pressure per technical data. More informa-
tion can be found here: page 10 (Technical data). Addi-
tional minor adjustments to the fuel bypass ALO valve may
be required to achieve a stable flame through the transition
between low and high fire.
? the burner is erratic and does not respond to adjust-
ment.
! Internal damage to the burner. Some parts inside the burner
are loose, dirty or burned out.
• Contact Eclipse for further information.
? the burner is unstable or produces soot, smoke, or ex-
cessive carbon monoxide.
! The air/gas ratio is out of adjustment.
• Measure all the gas pressures and air pressures. Compare
these pressures to the documented initial start-up settings
and adjust them where necessary.
? the burner cannot achieve full capacity.
! Air filter is blocked.
• Clean or replace the air filter.
! Gas pressure going into the ratio regulator is too low.
• Adjust the gas pressure.
? Cannot initiate a start sequence.
! Air pressure switch has not made contact.
• Check air pressure switch adjustment. Check air filter. Check
blower rotation. Check outlet pressure from blower.
! High or low gas pressure switch has activated.
• Check incoming gas pressure. Adjust gas pressure if neces-
sary. Check pressure switch setting and operation.
! Malfunction of the flame safeguard system (e.g. shorted-out
flame sensor or electrical noise in the sensor line).
• Have a qualified electrician troubleshoot and correct the
problem.
! No power to the control unit.
• Have a qualified electrician troubleshoot and correct the
problem.
! Main power is off.
• Be sure the main power to the system is switched to the
"On" position.
