Ice on OAK

[rickaa61]

Noticed a real lazy flame on my stove so went outside and the oak intake screen was what looked like plugged with snow. Cleaned the snow off and flame went back to normal. When I checked the oak vent where it comes into the house the hose was frozen on the outside at least 8" in. The Temps here in the last couple of days have been between 1 degree at night and about 11 during the day. Have always had condensation on the oak, so I don't think the screen was plugged with snow but actually frozen from the condensation. Pulled the oak off the stove and left it close enough to draw the outside air but if it freezes again can draw air from inside. Just wondering if anyone has had this same problem?

Thanks

The installers did a marvelous job with my stove. Installed the OAK directly below the 4" wall thimble. My exhaust goes out through the thimble, 90deg, then up 10'.
So what that means is that anything that hits the thimble and parts of the exhaust, drip down onto the OAK. If the OAK is at 10deg?...it freezes instantly, and after a bit of buildup, will block the vent holes and give me lazy-flame, no matter how open I run the stove.
Once it warms up a bit, I'll make a small shield to go over the OAK inlet and solve the problem.
