Eclipse RatioMatic Burners, RM Series, V5, Installation Guide 110, 12/3/2014
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.
Pilot set too lean, becoming unstable as air
increases.
Increase pressure into the pilot regulator.
Main gas adjusting valve not open enough. Increase valve opening.
Suction or back pressure in chamber
fluctuates, upsetting pilot stability.
Cross-connect pilot regulator vent to the
combustion chamber, but not via the burner
air pressure tap.
The burner is erratic and
does not respond to
adjustment.
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
excessive 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 gas pressure switch has activated.
Check incoming gas pressure.
Adjust gas pressure if necessary.
Check pressure switch setting and
operation.
Low gas pressure switch has activated.
Check incoming gas pressure.
Adjust gas pressure if necessary.
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.
Main flame too long and
yellow at high fire.
Gas flame is too high.
Gas butterfly valve is open too far or main
gas regulator spring is screwed in too far.
Main flame too short at high
fire.
Gas flow is too low.
Gas butterfly valve is closed too far, or main
gas regulator spring is screwed out too far.
Low fire (pilot) flame is too
long, soft or yellow.
Too much gas flow.
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.
