•
Adjust the low fire setting or open the airflow shutters if the smallest flame appears
die in air turbulence.
•
Inspect the flame rod wire for damaged insulation or exposed wires.
•
Make sure the flame rod wire and spark plug wire are connected correctly. The
flame rod wire is blue, the spark plug wire is black and looks like an automotive
spark plug cable with copper wire core.
•
Is minimum Gas Valve Motor (GVM) setting too low? See “Additional Settings”
section of manual for more information on the PV ALWAYS OPEN and PV OPEN
TO LIGHT ONLY settings.
ERROR 153
FLAME SIGNAL, BEFORE FUEL, BEFORE SPARK:
This ERROR is normally caused
by a malfunction or tampering with the flame relay (FLR). Also check for carbon build-
up in the burner head causing a short to the flame rod.
ERROR 155
FLAME BEFORE FUEL DURING SPARK:
This ERROR is caused by electrical
interference between the spark plug wires and the flame electrode wires. Separate the
wires to help eliminate this interference.
ERROR 160
WATER THERMOCOUPLE WIRING REVERSED:
The water temperature shows water
getting cooler after flame is established and water pump is running indicating reversed
thermocouple wiring. If this problem persists, try the following:
•
In the junction head of the yellow Thermocouple, check that RED wire is
connected to negative (-) junction and WHITE wire is connected to positive (+)
junction on transmitter. Reversing these wires will cause this problem.

ERROR 161
AIR THERMOCOUPLE WIRING REVERSED:
The air temperature shows air getting
cooler after flame is established indicating reversed thermocouple wiring. If this problem
persists, try the following:
•
In the junction head of the blue Thermocouple, check that RED wire is connected
to negative (-) junction and WHITE wire is connected to positive (+) junction on
transmitter. Reversing these wires will cause this problem.
