I have a peerless purefire boiler, PF-80, supporting radiant heat. It runs on propane and was installed a year ago. Since then, the system has gone out 15 times always with the same A02, flame failure message.
Peerless and the contractor have looked at this several times but seem to be stumped. While I can always restart the system, I am concerned about this in cold weather and when I am away from home. Any thoughts on where to go from here? Thanks for any advice you can provide.
