DuraVent Model BV Quick Grip Firestop and Support: a floor plate that grips and holds the vent
The DuraVent Model BV Quick Grip Firestop and Support is a one piece floor plate that holds the gas vent. It sits above the joists, the beams beneath the floor. With its gripping fingers facing upward, the plate catches and holds the pipe as it is pushed through from below. It can carry up to 30 feet of vent. A taller run needs another support. 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.
Choose a 3, 4, 5, or 6 inch diameter to match your vent. The floor opening must leave a 1 inch air space around the pipe. For a vertical run, a support near the bottom carries the weight. Each floor or ceiling crossing also needs a firestop, which closes the opening around the vent, and an attic needs an attic shield. Sideways sections need support every 5 feet. Need a support rated for 35 feet? See the DuraVent Model BV Support Assembly plate and band. The DuraVent Model BV Quick Grip Firestop and Support ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
