I have a Teledyne Series 2 325btu heater that has worked well for 2 years (since I bought my house). This year, the automatic elec pilot ignition fires and lights the burners. It roars to life for about 10 seconds and then shuts off. It tries this again automatically and then just quits altogether. Could this be the automatic flow control valve sticking? I guess whatever it is seems like it triggers the high limit switch, because it shuts off so quickly.
As a side note, the spa heater won't fire at all if the ground is wet after it rains (the pilot clicks like it is trying to fire, but no gas burns...sometimes it shuts down if it goes over 90 seconds, i understand how to reset it) - the guy who sold me the place says it is because the heater can't get a ground. Everything is grounded with a copper rod in the ground that was also installed. Is there a better way to ground? Is this actually the problem?
Thanks for any and all advice!!
