Its been a while since I've done a power vent and I can't exactly remember
the nuts and bolts of it, but no, it shouldn't run continuously. The water
heater aquastat should initiate the blower sequence. Once the blower starts
it closes a circuit on a pressure switch allowing the burner to start. Once
the aquastat is satisfied, the blower either shuts off or goes through a
timing cycle and then shuts off

Hi all. I have a 7 year old Power Vent Hot water heater. It heats
water just fine, but my problem is that the blower keeps running. It
never shuts off. I never noticed this before & I'm just not sure if
it's a problem. Can anyone answer ?
- Should it run all the time?
- If not, what controls it?
- Have you ever seen this problem before?

Thanks in Advance!
Ron
