Are you worried about your local weather negatively affecting your chimney system? Dura-Vent has just what you need to protect your b vent pipes from storm damage with their 4GVVTH High-Wind Rain Cap. This rain cap features the same reliable construction as the rest of Dura-Vent's b vent system, with an aluminum inner pipe and a galvanized steel outer shell resistant to damage. The specialized head is perfect for regions that experience high winds and frequent storms, and Dura-Vent's GV system is approved for a wide range of gas appliances.
Please Note: This venting system is only approved for gas fireplaces and appliances. Always refer to your installation and owner's manuals for approved venting systems.
Customer Q&A with Product Specialists
Brooks B.
from Kentucky asked:
What is the difference between Duravent 4BVVTH cap and 4GVVTH cap?
DuraVent's 4" type B vent pipe has changed from the "4GV" components to the "4BV" components. The 4BVVTH cap is for the newer, current 4BV pipe. The 4GVVTH cap is for the older, discontinued 4GV pipe. These are not interchangeable.

Allen
from Greenup, IL asked:
What is the dimension of the collar on this item?
The only dimensions available are the 4" diameter dimension. This cap is designed to lock into position with Dura-Vent Type B Gas Vent pipes only and cannot be used with any other type or brand of pipe.

Martin
from PA asked:
Is it okay to use this cap on the wall with a horizontal application?
B-vent appliances are not usually able to be terminated horizontally. As such, horizontal vent caps are not readily available and this vertical cap would be the only choice. It is important to note that most manufacturers of appliances that vent horizontally have a specific cap that they offer.
