Remove the Unitherm Governor and test it in water to see exactly what temperature it opens at.
What temperature is stamped on the Unitherm Governor?

Raypak had us remove UVG and then run heater and sound gone.
This is the key information.if not running with UVG then no sound
Well the crew has been out here for hours. All gas is in spec including dynamic. No better. With the thermostat out no noise. We have tried 3 thermostats they all function based on water test. Open around 110 and start closing when water is colder. Everyone is at a loss. Have had it 6 weeks and still no heater. Any thoughts. Raypak tech line has really not been of any help except selling us thermostats.Gas pressure, there is an inlet port on gas valve. You want to test static pressure and turn on the heater for dynamic. There is also a port on the load side of gas valve for manifold pressure. The specs are above and you can adjust regulator at gas valve . If any appliances were on at the same time this could alter readings.
Sounds like the flow through the heater is the problem. Maybe broken internal bypass, open external bypass, heater is plumbed in backwards that is causing the thermal regulator not to open all the way.The second thing I tried was to go to one of my fill lines to the pool and slowly shut the valve and that also worked but I could hear my pump straining.
The system was flipped from right to left because of my pump configuration. They followed rapak directions for flipping. I have checked skimmer clear great suction, bottom drains clear. I opened sand filter which sand was replaced 2 years ago really nothing much on top.Pictures of the system?
Tried that and they said I have to deal now with Raypak authorized warranty repair. Nobody within 90 miles and they won’t make the trip. So I’m just beginning to figure out a battle plan here. Kinda screwed now and ****** at $4500 sitting idle and no one cares.Maybe they made a mistake when they flipped it?
In any case, I would tell them to get it fixed or give you a new heater.
I care, not that it does you much good. LOL.at $4500 sitting idle and no one cares.
