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.
Slight vibration can
cause noise in the
residence
(This is not a
warranty issue)
Use flexible gas line to insolate the vibration noises between the gas valve and the
line.
Don’t hang gas lines from floor joists.
Use rubber insulators with gas line supports.

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.
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 thermister curves for diagnosing the water and outdoor air sensors.
1. Measure the resistance of the thermister when disconnected.
2. Using the appropriate chart, find the resistance and move either vertical (water probe) or
horizontal (air probe) until the line is intersected.
3. Move 90 degrees to the corresponding temperature.
4. If the temperature is plus or minus 10 degrees, then the probe is operating correctly.
