DuraVent FasNSeal W2 23 Degree Bird Screen: a screened end for a double wall vent
The DuraVent FasNSeal W2 23 Degree Bird Screen is the screened end for a vent that exits through a wall. It has a 23 degree turn. The screened end helps keep rain, birds, and debris out of the vent. FasNSeal W2 is DuraVent’s double wall stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, with an air space between its two walls. Choose a size from 3 to 16 inch on this page to match your W2 vent. These sizes refer to the inside diameter, not the outer wall.
The stainless steel outer jacket surrounds the inner exhaust pipe with 1/2 inch of air between them. That space helps shield heat and reduces the room needed between the vent and materials that can burn. In homes, DuraVent points to W2 for runs inside walls or between floor joists. The appliance maker’s distances from windows, doors, and other openings still apply to this wall ending. Need the single wall version? See the DuraVent FasNSeal 23 Degree Bird Screen for single wall vents. The DuraVent FasNSeal W2 23 Degree Bird Screen ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
