Energy recovery ventilator

marjan2 | Posted in General Questions on

I was reading an article on your website about how to install an ERV. It said that the fresh air intake had to be 10 feet from the furnace on the return side, 3 feet down from the stale air exhaust. My ERV exhaust is in the return side but the fresh air intake is on the supply side. And I don’t have room enough to put the fresh air intake over on the return side. What I’m wondering is why does the fresh air duct have to be 10 feet from the furnace and is it OK to keep it where I have it? Also I’m going to be putting a whole house humidifier on my furnace. Will this interfere, either way, with the way I have the ERV hooked up. Thanks

    Can you tell us the make and model of the ERV?

      It's an Ultimate Air 200. They have gone out of business I think because of covid and I can't get through to them. Thanks

    Can you look at this document and identify how your unit is installed?
