Re: Generator doesn't work with Direct Vent Hot Water Heater

said by Frink:

Got it, so if I have two 120v 3 prong outlets on my generator, one gets the modified plug, and the second just goes to the WH?

Yes exactly, you gotta sacrifice one outlet for the modified plug.

If you can wait, I would hold out until one of our pros come to comment in this thread. I'm not even sure if I would do this modification myself without having my generator's chassis grounded to the house's ground.

I`m an AO Smith warranty service agent, and I can honestly say I havent run into this situation yet.

The control needs a good ground to prove flame properly. If you bond the water heater to the ground rod, it may work. (ie-- run a #14 conductor from chassis ground on the heater to the ground rod)

I know generators can provide noisy power. I have seen noisy power/bad power kill a powervent control. Hope you dont let the smoke out..

good luck, stinky :P
