Well, the max e therm 333 heater may be done. It's not firing up and I'm afraid the combustion chamber is under water, I'll know this weekend when I remove bolt from manifold.
Looks like a new one is in my future, but my question is.....has anyone piped a bypass to be able to valve off the heater? Another option is just getting a couple of fittings that will
screw on where the heater inlet/outlet connect. I'd like to be able to make some fittings to go onto the heater water connections where I can hook up a water hose and pump/bucket
system and flush the tubing with acid/water solution to keep it from scaling.
Other question is, can I get the 400 BTU unit instead of 333?
