Metal-Fab Type B Round 90-Degree Adjustable Chimney Elbow - 3" Inner Diameter - 3M90

Components of this system effectively vent Category 1 appliances such as gas-fired fireplaces, furnaces, water heaters and boilers. The elbow adjusts from 0 degree to 90 degree and the collar rotates 360 degree so you can get a proper orientation. The outer wall is 0.018" galvanized steel and the inner is 0.012" aluminum alloy with an insulating air space of 1/4". The double-wall design allows 1" clearance to combustibles. Connections are made without tools because of the SureLock locking system and sharp edges are eliminated by the hemmed flue and casing. This elbow is compatible with other brands of 3" UL listed round gas vent pipe. This item is listed to UL 441 and carries a limited one-year warranty.
