I have had my house and pool since Fall of 2009 and have never cleaned the burner assembly on my pool heater. I have decided to give it a try this year before opening the pool and I hope that this will help with the efficiency of the heater as well as keeping it in good shape. The pool heater that I have is a Pentair MiniMax Plus 400 Natural Gas.
The burner assembly seems to be a bit difficult to remove and disassemble and of course reassembling any tips or advice to for this type of work?
I have vacuumed the heat exchanger each year when opening the pool but there is still a good amount of soot on it. Any ideas on how to clean this better with it still in place or is removing it and using a cleaning solution the best idea here?
