Boiler will
not stay lit.
Indicates lack of a flame signal.
In order to stay running the flame
signal must be at least 0.7 µAmps
1.
If the Burner light on the Burner (Red) Control is going
out, go to “Burner shutting off”.
2.
Check condensate drain for blockage and check the inlet
piping for ingested snow or water (if the flame rod gets
wet, it may need to be replaced). Check for resistance
from flame rod to ground, must be an open circuit (O.L),
if not, remove rod and bend it away from the burner
slightly.
3.
Check for proper polarity of line and neutral wiring to the
boiler.
Boiler
bangs or
hisses
Bangs or sounds like a kettle
while burner is running indicates
insufficient flow
1.
Ensure the plumbing is as shown in manual. Check to see
if pumps are operating properly and water pressure is
above 15psi. This problem can lead to boiler
overheating!
2.
Boiler may be plugging with scale or magnetite, clean
with Fernox DS-40 Descaler and Cleanser (NTI PN:
83450).
3.
If glycol is being used the concentration may be to high,
recommend using a concentration lower than 35%.
Boiler
Lights
rough or
pulsates
Typically an imbalance in the Air
to gas ratio
1.
Ensure that the venting lengths are in compliance with
Section 4.0
2.
Ensure that the line pressure during operation does not
drop more than 20% from the static line pressure.
3.
Momentarily remove the intake vent from the boiler
during ignition, if unit lights smoothly with intake vent
disconnected reconnect and check for proper combustion
if unit maintains smooth operation after ignition. (See
Section 9.0) Calibrate for proper combustion. If
problem persists contact NY Thermal.
4.
Heat exchanger may be dirty, remove burner door and
inspect, clean if necessary.
Fan appears
to be
creating a
noise in the
house
Slight vibration can cause noise in
the residence
(This is not a warranty issue)
1.
Use flexible gas line to isolate the vibration noises
between the gas valve and the line.
2.
Don’t hang gas lines from floor joists.
3.
Use rubber insulators with gas line supports.
Making a rubbing noise.
((This is not a warranty issue))
1.
If gas valve is not held when the gas nipple is connected,
the force of tightening the fitting can damage the valve,
and warp the fan housing.
2.
If pipe is used, the gas line must not create any forces to
the valve, either vertically (weight of line), or horizontally
(misaligned connection)
