DuraVent Model BV Wall Support and Band Assembly: carries the weight of a vertical gas vent
The DuraVent Model BV Wall Support and Band Assembly is a wall bracket and band that holds a vertical gas vent steady and carries its weight. It supports up to 35 feet of pipe while keeping a 1 inch air space between the pipe and the wall. Space these assemblies no more than 8 feet apart along the run. Model BV is DuraVent’s Type B gas vent, the double wall pipe that carries the exhaust from a gas furnace, boiler, or water heater out of the house. Air between its aluminum inner pipe and galvanized steel outer pipe keeps the inside hot to help exhaust rise while the outside stays cooler.
Choose the diameter that matches your vent: 3 to 8 inch, or 10 and 12 inch from the larger diameter range. This assembly can also steady the pipe where a bend shifts the run sideways. When planning weight support, remember that an adjustable pipe section cannot carry the pipe below it. Only need to steady the run? See the DuraVent Model BV Wall Band strap. The DuraVent Model BV Wall Support and Band Assembly ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
