I have a power vented gas hot water that on occasion does not turn on to heat the water. However, if I unplug and plug it right back in it starts right up. Then it could go for days before it does it again. Please help. Also, I am not sure I really needed a power vented hot water heater. The vent pipe is PVC and runs nearly vertical from my basement through the roof of my one story rancher. When is a power vented water heater required? If its not required perhaps I am better off replacing it with a non power vented model.
State Select Power Vented 50 gal Gas Model PR650N0VET
Thanks

Th epproblem you are most likely have is from a safety called a flag switch usually located either in the blower or right past it. When you unplug and replug you reset the switch. Sequence of events.
1 fan comes on.
2 switch is made from the airflow of the fan.
3 ignitor come on
4. main gas valve opens and ignitor starts flame.
You are being stopped at step 2 when the fan does not move with the air. This shuts off and out the water heater from calling again. Find the fan switch and make sure it moves easily. They get dirty and also dry from lack of lube.
Good luck.
Greg. I think you might have found it. If it says manual reset,the you have to reset it somehow by moving something. The switch is that flat pice of metal and the button is the reset. It may even say Klixon(A brand) on the switch. I works off a pressure differencial. If the preasure for one side to the other is too much, it clicks off and then has to be manually reset with that button. I was just a thought. It that was dirty, then the fan blades and fan motor ae also dirty and need to be serviced(cleaned and lubed).

I could not find a flag switch in and around the blower housings. But, on the blower/hood assembly there is a hole with a clear plastic hoes attached and a switch indicated as a "venting manual reset switch" in the manual. This switch does not seem to have any moving parts. It is just a plat plate in the housing and a button on top that doesn't seem to do anything. Anyway, the entire area was dirty go I cleaned it all up. Any other suggestions?
Thanks for your help
Greg
