Greetings -

I visit this forum occasionally (great resource!), but this is my first post.

I noticed the radon levels in my home elevated when I replaced my atmospheric venting water heater with an A.O. Smith GPVH 40 100 power vent model.

The levels are still below the safe level in warm weather, but in the winter when a low pressure system rolls through the levels rise above the EPA recommended action level (4 pCi/l) in my unfinished basement.

I know that you can run 2-pipes (intake & exhaust) on some power vents, but my manual doesn't mention anything about this.

Can I pull air from the exterior through an an intake pipe with this model?

If not - any other recommendations?
