Start-up sequence runs but
burner does not light.
(Continued)
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 ImmersoPak Datasheets, series
360 for fuel orifice and the 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.
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.
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 your Eclipse representative or
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.
Tube back pressure is limiting
performance.
Review system design.
