The problem I have is the air heater shutting down in windy days and I'd like to figure out how to fix this issue.
Here's the setup: The back of the house faces North to an open field which gets very windy. The winds are very strong on that side and hit right up against the north wall the house. That's exactly where the air heater intake/exhaust sits.
It is about 1.5 feet above the ground. The pipes run through the wall and in a straight line to the heater in the basement.
When the winds are really bad (like the blizzard we recently had) the fire jets from inside the furnace get blown out. The heater attempts to restart about 3 times then it locks out because it can't stay up and running.
In this photo you can see the type of intake/exhaust termination I have. The big hole in the middle is the exhaust. The intake is the gap in between the wall and this piece.
When the winds hit the side of the house, they go along the wall into the intake.
How can I prevent this from happening when the next blizzard will hit?
Moving the ducts to other sides of the house is not really plausible. The only side that might work would be on the east, but it also could get very strong winds.
During the last blizzard I improvised a wind blocking wall in front of the vent, but it did not work. The wind hits the side of the house and goes down along the face of the wall into the intake.
I guess I could have some sort of a barrier attached to the wall around the intake. But that could end up being an eyesore.
