Problem Solution
Boiler fails to operate Check thermostat for proper temperature setting
Is electrical power supply to boiler on?
Is manual shut-off valve in gas supply pipe in open position? (Follow start-up procedures if you open gas line.)
If you have a manually ignited continuously burning pilot Be sure that it is burning. If not, see the start-up procedures in this manual
Control dial on gas valve in ON position? (Follow start-up procedures if you must reset dial to ON.)
If your boiler still fails to operate Call your service representative

Error Code Number Definition Consequence
4 Flame current too low. Check for flame. Non critical alarm
6 Flame sensed out of normal sequence (before opening or after closing gas valve). Soft lockout
18 Gas valve relays welded. Five consecutive soft lockouts. Hard lockout
23 Flame sensed during prepurge (before gas valve signaled opened). Soft lockout
32 Sensor 1 error. Temperature sensor in well is not reading correctly. Verify it is connected to board. Replace if necessary. Wait for recovery
55 Atmospheric damper end switch failed to close (end switch contacts stuck open).
56 Atmospheric damper end switch failed to open (end switch contacts stuck close).
57 Igniter flame rod shorted to burner ground
58 Igniter flame rod shorted to burner ground. Repair or replace igniter.
59 Line Voltage error – voltage out of specification high or low (15-37V (44-66Hz))
60 Applies only to thermostats having on-board transformer. Polarity is wrong in this case.
Thermostat input higher than threshold.
61 Line voltage unstable – possibly too may heavy loads switching on and off causing erratic supply voltage.
62 Soft lockout: maximum number of retries exceeded. (For pilot ignition) Soft lockout
Soft lockout is reset after one hour if alarm reason disappears.
63 Soft lockout: maximum number of recycles exceeded. (After main burner ignition)
64 Soft Lockout – electronics failure. On-board self diagnostics detected error.
65 Over temperature error. Sensor measured temperature in excess of maximum allowable limit. Hard lockout
