View Full Version : wind blowing out pilot light

my gas water heater is in an outside closet/shed. When it is windy outside, the air comes in via the vent and blows out the pilot. I've asked a plumber if I can rig a baffle on the sides of the vent and he says absolutely not. What exactly is the purpose of the vent...is it only for venting fumes or does it supply air so the pilot stays on, that is, supplying oxygen? If I could move the vent lower, it wouldn't be as vulnerable to wind. At what level must the vent be in order to serve it's purpose?
Appreciate your help.

Do you have a proper vent cap (louvered) and does this roof vent terminate within the code specs in your area?



If the vent doesn't terminate at the right level in conjunction with the roof line, problems as you describe can happen.


As that plumber stated, you cannot restrict the opening of the flue, thus causing even more problems.


Venting is crucial for any gas-fired appliance that is sized according to btu load.

Improper venting of gas appliances can lead to death. Don't take a chance in your situation and have the pro's deal with this issue, and determine the problem.
