DuraVent Model BV Oval Base Plate: connects oval vent to a recessed wall furnace
The DuraVent Model BV Oval Base Plate is the plate that joins a 4 inch oval vent to the top of a recessed gas wall furnace. It snaps onto the bottom of the first vent length and fastens to the furnace’s top plate with two screws. DuraVent calls it a hold down plate and requires it for a Type BW connection, the vent connection for a recessed wall furnace. 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.
This plate works with oval firestop spacers to establish the clearance inside a 2 by 4 wall. Each oval kit already includes one. The 4 inch oval vent is listed for both Type B and Type BW use. For a wall furnace, DuraVent calls for at least 12 feet from the furnace bottom to the vent cap. Oval Model BV parts are for USA use only, not approved or sold in Canada.

The DuraVent Model BV Oval Base Plate ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
