Hello...I recently picked up a used Hayward H300 milivolt propane heater on CL...Before I became the proud owner, the heater had been bought and sold a couple times, with both of the previous owners never having actually hooked it up...so no one really 'knew' anything about it. I now have it all hooked up and of course, it isn't working.
I can get the pilot to ignite and stay lit, as long as I continue to hold down the pilot gas knob on the gas valve, and while holding down the knob, there is a strong blue flame...but once I let it go, the flame either goes out completely, or is very faint and when I attempt to turn the gas knob to the 'on' position, nothing happens.
I traced the troubleshooting flowchart from Hayward and it seems to indicate a bad gas valve? Can anyone substantiate this? The HAXGSV0003 MV gas valve seems pretty expensive and I would prefer to have an accurate diagnosis, before purchasing it...
