Is there an exhaust vent accessory item, that I can install on my natural gas Hot Water heater? Several times a year, the local winds will extinguish our HW pilot.
I sure would prefer to have an in-line or at the vent exhaust cap, an "item" that will prevent those Down Drafts (that blows out the pilot light).
Does such an item exist?
Yes, you want a flue cap. Many kinds available for any type of flue.
...and remember, you don't have to heat *hot* water...
Sorry to take a sideways run with this response, but...
My WH is in its own little closet, and the pilot would occasionally blow out when winds were strong. I noticed a large gap at the bottom of the closet door, and cut a piece of wood to make a "jam" to block off most of the gap. That was 20 years ago, and the pilot hasn't blown out since.
Hope it gets make up air for the combustion, some how.
