The Metal-Fab 14MF is a standard flashing for Type-B gas vents. This product is made from steel and suitable for roofs with a pitch of two-twelfths to five-twelfths. It is designed for use with category one gas appliances, including furnaces and boilers that operate at non-positive vent static pressure.
This flashing includes hemmed flues and casings to support efficient venting. Its twist-lock design takes the hassle out of installation by removing the need for additional screws.
