Is only for use with Dura-vent piping or can it be used with standard piping?
By Tyler M. - Fireplace Specialist on July 20, 2012
Answer:While this is a DuraVent item, it may be compatible with your pipe, as long as you are certain you are installing it on Type B pipe and the inner diameter of the pipe is 5 inches. However, the ultimate call is made by the manufacturer of the appliance that you are venting, so you may want to check on that before purchasing this cap.

My tankless water heater won't come on when the wind is 20 plus miles an hour from N NW. Bosch Aqua Star told me to get a high wind vent cap. I ordered one and it looks the same as my old one and sure enough no hot water in a 20 mile an hour wind from the N NW. I see the Dura Vent looks
completely different to mine. Is this the type that I need for my problem? Mine is a round vent with slots all the way around it. I see yours has some solid panels. I had thought of covering mine on the N NW side. Don't know if it would be dangerous.

Answer:This cap is indeed designed to protect your B-Vent appliance during bouts of high wind. However, it is only designed for use with Simpson Dura-Vent chimney systems. It features twist-lock tabs that are specific to this line of chimney pipe. So, if your pipe is made by Simpson, then this cap will work for you. We would not recommend covering any part of your cap. The potential restriction of draft that this would cause could create problems for you on even calm days.
