I believe I have a broken or stuck bypass insert and possibly a bad thermostat. I had a grid from the de filter break a few months ago and send a few pieces through the heater. I believe I got all of the pieces out however now when I turn on my heater it begins to make a boiling sound after about a minute of operation.
I purchased the items to install and would like to tackle it this weekend. I know nothing about the heater but from the manual it doesn't look like there's much to it however its not 100% detailed either.
I have attached a few pictures for reference. If I am correct and please correct me if I am not I believe I need to kill power, turn off gas, drain the bypass valve, loosen the two union nuts on plumbing, then loosen and disconnect the 2 nuts for the hi-limit switch*, disconnect the pressure switch tube*, and disconnect the thermostat bulbs*, remove the 12 nuts on the bypass valve and pull forward.
* Any special procedure or precautions I should take in removing these?
Once this is all removed I'm hoping to see the way everything needs to go back in from the look of the old parts.
Any and all help is appreciated.
