I'm wondering what kind of vent cap is best to prevent pilot light from being blown out in high winds. This happened last week - first time I have ever seen it done.
This unit is in the garage, all to code (18+ inches above grade, pipe/vent/etc approved and to code, etc). Distance from top of the water heater to the roof is about 5 feet, vent duct goes straight up a few inches, then at 45 deg angle for 2-3 feet, then straight through and above the roof to code. Distance from roof to cap is to code. Basic cap is code.
