Building Code question (HVAC)

[toxic111]

As long as you have minium clearances from the B-Vent (usually 1") you should be fine. The ends of the ducts will have to be seperated though.

Thanks, but can you clarify about the ends being separated though? Mean the joints off the B-Vent staggered from those of the HRV line?

[toxic111]

The exhaust ends must seperated so there is no back drafting of gases.

The only code requirement is 1" clearance, if you run metal pipe for your hrv, you can touch it.

This is great. The other option would have been to open the walls and wasn't looking forward to doing drywall.

Still can't believe I was quoted 4000 bucks for a HRV installed.

and how much was the unit without the install?
