Ive never worked on the pool heater models but from the pdfs they dont
seem much differant than the regular copper fin boilers.
Did you happen to have your U tube on the inlet and outlet side to see
whats happining when the valve gets 24v? The only pressure tube
problem Ive had on Lochinvars was the barbed fitting that goes into the
burner was plugged with what looked like red Loctite. I cleared it and
it fired right up. This tube that goes to the GV from the pressurized
burner box, does it go into the GV vent? What did the rep have to say
and what did they check? Does the GV have a steady voltage and just
wont open or does the voltage drop out. What are the pressures when
its tring to fire?
Its probably something stupid. One time I couldnt get a new Trane RTU
to fire. I spent about an hour taking pressure measurements and
dicking around. Then Im standing there and look over my shoulder and I
see it. The Gas pressure regulator. I checked out the vent and sure
enough it was plugged. Its easy to get wound up on the complex things
and overlook the simple ones.
I dont think its a water side problem as BP suggested. But speaking of
that, do make sure the flow switch works. It wont take long to burn up
the HX with no flow.
