The burner does not light or goes off
when it cycles to high fire
Burner set too lean, becoming unstable
as air increases.
Adjust the settings to provide more
gas.
Insufficient pressure into ratio
regulator.
Adjust the pressure settings on the
main gas regulator or change spring.
Main gas adjustment valve not open
enough.
Adjust the main gas adjustment valve.
Marginal air pressure switch setting.
Adjust the air pressure switch setting
Gas pressure switch set incorrectly.
Adjust switch setting.
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.
The burner is unstable and produces
soot, smoke or excessive carbon
monoxide
The air/gas ratio is out of adjustment. Reset the burner controls and clean
ignition rod and UV scanner.* See
“Adjustment, Start & Stop” section.
Bleed fitting (if used) is dirty.
Clean fitting. Check and clean filters,
spark rod and UV scanner.* (If
necessary).
* After this step it is important that you clean the spark rod and UV scanner, and
make sure that there is no excessive soot on the nozzle. Clean where
necessary.
Burner pulsates or produces noise
Acoustic feedback from tube.
Slide a piece of steel plate over the end
of the tube until the rumbling
disappears. Weld the plate in place.
Readjust the burner controls if
necessary.
Input inconsistent with nozzle settings. Check if input is consistent with nozzle
settings and adjust if necessary.
Too much air.
Check oxygen levels and adjust to 2%
to 4% O
2
(at high fire).
Burner could be improperly set to fire at
an input rate which exceeds its
maximum rated capacity.
Check the pressure drops to verify that
the inputs are at the correct levels.
Reduce the input on the air and gas as
required to achieve the specified
inputs.
Negative pressure in the building.
In some cases, building exhaust
systems create a negative pressure
that “pulls” on the exhaust outlet of the
tube. By placing a washer or restriction
pate over the tube outlet, this suction
can be equalized by burner pressure.
