Girard Tankless water Heater

[obi]

My hot water isn't working, I am getting one flash from the inside light of my Direct spark igniter. According to the owners manual, one flash means Air Fault but it does not say what to do about it. I can't find anything in my internet searches. I see no obstructions and I purged the relief valve, all water faucets, checked all connections and the sail switch. I don;t hear the blower come on however when I turn the water off and on I can hear a switch click and I can smell propane. The power seems to work as well. Any Ideas anyone?..

Thanks,

Obi

Take a wire and jump the blower switch. That is the white one that is connected to the arm that detects the air flow. If that doesn't turn it on jump the rest of the safety switches. Warning do not leave the jumper in place this is only to trouble shoot. Also Monday call tech support. They are in California so you will have to wait until they open. Another thing to check is make sure that the arm in front of the blower is moving freely. In the instructions manuals it gives the codes. That might help also.

Sorry to jump the switch you will need to disconnect the wires first.
