PROBLEM
POSSIBLE CAUSE
SOLUTION
Repair the leak in the loading
line.
The burner is erratic and does
not respond to adjustment.
Contact your Eclipse
representative or Eclipse
Combustion for further
information.
The burner is unstable or
produces soot, smoke, or
excessive carbon monoxide.
The burner cannot achieve full
capacity.
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.
Too much gas:
•
Wrong or missing burner fuel
orifice.
•
Not enough gas flowing to the
burner.
•
Not enough air.
•
Not enough gas pressure into
the ratio regulator.
•
Loading line to the ratio
regulator is leaking.
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.
Check RatioAir Data Sheets,
Series 115 for fuel orifice and
the given fuel.
The low fire flame is weak or
unstable.
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.
The burner goes out when it
cycles to high fire.
Check the start-up settings.
Measure the gas pressures and
adjust them where necessary.
Check for valve train pressure
loss.
Start-up sequence runs but
burner does not light.
