Problem
The burner does not light or goes off
when it cycles to high fire
The burner is erratic and does not
respond to adjustment
The burner is unstable and produces
soot, smoke or excessive carbon
monoxide
Burner pulsates or produces noise
Eclipse TFB, V2, Installation Guide 310, 11/14/2014
Possible Cause
Burner set too lean, becoming unstable
as air increases.
Insufficient pressure into ratio
regulator.
Main gas adjustment valve not open
enough.
Marginal air pressure switch setting.
Gas pressure switch set incorrectly.
Internal damage to the burner, some
parts inside the burner are loose, dirty
or burned out.
The air/gas ratio is out of adjustment. Reset the burner controls and clean
Bleed fitting (if used) is dirty.
* 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.
Acoustic feedback from tube.
Input inconsistent with nozzle settings. Check if input is consistent with nozzle
Too much air.
Burner could be improperly set to fire at
an input rate which exceeds its
maximum rated capacity.
Negative pressure in the building.
Solution
Adjust the settings to provide more
gas.
Adjust the pressure settings on the
main gas regulator or change spring.
Adjust the main gas adjustment valve.
Adjust the air pressure switch setting
Adjust switch setting.

ignition rod and UV scanner.* See
"Adjustment, Start & Stop" section.
Clean fitting. Check and clean filters,
spark rod and UV scanner.* (If
necessary).
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.
settings and adjust if necessary.
Check oxygen levels and adjust to 2%
to 4% O (at high fire).

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.
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.
