LF HRV installation pictures

[mark]

Fully ducted would have been best but since I was installing in a house complete with finished basement still think having a separate stale intake with fresh air tied to furnace a good compromise (middle picture). Think my numbers also show it worked out okay.

Here's a diagram of installs

yes.

how did you do picture 2 if your house is finished?
picture 2 is better than picture 3 but very rare to see as you also need the house open to do that. tell u the truth Ive heard of it but never actually seen picture 2 style.


most people do picture 1 or 3.

Though furnace is wall vented, convention gas hot water heater and luckily there was room in the chimney chase. Still have the option of running a branch for stale air intake to main floor bath if ever felt like squeezing through the attic again.
