ADAPTABILITYMetal-Fab round B-Vent has been evaluated and listed by Underwriters Laboratories, Inc.,to mate with other specifically identified and UL listed round gas vent, in 3" through 6"diameters. Metal-Fab's approval covers connections at both the male (outlet) end, andthe female (inlet) end to the following B-Vent products:
General Products Co., Inc. (Airjet)American Metal Products Co. (Amerivent)Hart & Cooley (Metlvent)Household Manufacturing Inc. (Metalbestos & Airmate)Mitchell Metal Products Inc. (Mitchvent)Selkirk Metalbestos (Metalbestos)Simpson Dura-Vent Inc. (Duravent)ECCO Heating Products (ECCO Manufacturing)
At the male (outlet) end of compatible gas vent, add an adapter or adjustable length (M6A,M12A, or M18A) - then add sections of Metal-Fab pipe. At the female (inlet) end ofcompatible vent simply insert the male end of Metal-Fab B-Vent into the compatible gasvent and secure per instructions.
MATERIAL SPECIFICATIONSThe outer wall is constructed of galvanized steel, .018" thick G-90 for sizes 3" to 14" diameter, and .024" thick G-90 for sizes 16" to 30" diameter.
The inner wall is constructed of aluminum alloy, .012" thick for sizes 3" to 8" diameter and .018" thick for sizes 10" to 30" diameter.
The vent includes an integral, annular insulating air space, ¼" thick for sizes3" to 6" diameter and ½" thick for sizes 7" to 30" diameter.
