18 V ENT /F LUE P IPE & C OMBUSTION A IR P IPE In a basement installation, the vent/flue pipe can be run between joist spaces. If the vent pipe must go below a joist and then up into the last joist space to penetrate the header , two 45° elbows should be used to reach the header rather than two 90° elbows.
