Possible Remedies
Press the Reset button to clear the error code.
If Error happens again:
1. Monitor the gas pressure to the appliance while in operation. Ensure pressure
is between 3.5 and 10.5" WC (Natural Gas), or between 8 and 13" WC for boilers
converted to Propane (LP) operation.
2. Check gas valve wire. Ensure connection is secure.
3. Check flame detection sensor. Ensure connections are secure. Normal operating
settings are more than 2.5DC before ignition; less than 2.5DC after ignition.
4. Check igniter transformer for proper connection.
5. Clean the spark igniter with steel wool to remove oxides. Ensure proper separation
(3-4 mm).
6. Replace the spark igniter if damaged.
7. Ensure that the flame is stable when lit.
8. If the problem persists, replace the main control.
This Error Code will go away when the condition is remedied.
1. If Error happens again disconnect the flame detection electrode.
Then press Reset.
2. If the error does not happen again replace the flame detection
electrode.
3. If the error happens again replace the main PCB.
