    There is definitely something in the air. My phone is ringing so much I can't get my work done. It's a paradox.

    I'd say Mr. Nadle is correct. -16 here this morning. Chilly! My wife will be driving the kids the 2 miles to school this morning. Too cold to take chances. Brrrrr.

    If not for this site, I would've had to call a pro for a dumb iced over intake vent last weekend...hopefully others find the same excellent help!

    In my useless and minority opinion, if you have a Mod-Con boiler and the intake is freezing/icing up, you have cross contamination and are sucking exhaust into the intake.

    If it is -16F outside, there is little to no available moisture in -16 degree air but the exhaust air is saturated to the point that it makes clouds or fog. The surface of the intake at the outside of the building is -16 degrees. Water vapor may not freeze until it is as low as -40. The vapor only needs a frozen surface that is at least 32 degrees to freeze on. You need more separation between the exhaust and the intake. For your location, they need to be a minimum of 30" from the ground. Probably more.

    If it is making up ice on the intake and blocking it when it is that cold, I would consider taking the boiler cover odd until it warms up. It could get messy.
