Matrix Installation and Operation Instructions
Symptom Detected
Problem
Solution
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 then 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 3.4
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
5.2) Calibrate for proper combustion. If problem persists contact NY
Thermal.
4.
Heat exchanger may be dirty, remove burner door and inspect, clean if
necessary.
Slight vibration can cause noise in
the residence
(This is not a warranty issue)
1.
Use flexible gas line to insolate 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.
General
Fan appears
to be
creating a
noise in the
house
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)
The following are the thermistor curves for diagnosing the water and outdoor air sensors:
Measure the resistance of the thermistor when disconnected.
Using the appropriate chart, find the resistance and move either vertical (water probe) or horizontal (air probe) until the line is
intersected.
Move 90 degrees to the corresponding temperature.
If the temperature is plus or minus 10 degrees, then the probe is operating correctly.
