Help with Jandy LXI400N heater.

Postby Riker0007 » Mon 10 Jun, 2019 23:05

So, I had to replace my gas line as it was leaking and I found out the previous plumber did not wrap the pipe and it rusted and they failed to tighten enough one pipe that was under concrete. After everything was tested and good, I tried to fire up the heater (jandy lxi400n) and the blower turns on, I hear the gas valve ( I think) click on and then a poof and it heats what gas is in there but never turns on. At the gas meter I can hear the gas being drawn but only for a sec or two. I took apart the igniter and it looks fine and tested about 58 ohms. The flames sensor looks fine too. I'm not sure what is the issue? Gas valve or Fenwal ignition unit?
I hate to buy parts only for it to be something else. Any help would be great.
THanks in advance.

Did you purge the air out of the new gas line
