Venting Considerations
*Notes—ALL venting considerations
• Dimensions of venting are based on
using Dura-Vent elbows. Elbow curve
radius dimensions will vary when using
other brands. In general, other brands
have slightly bigger radius.
• 3 inches clearance to combustibles
required above horizontal pipe. Slope
horizontal pipe upwards 1/4 inch per
foot. 1 inch clearance required around
sides and bottom of horizontal pipe and
around vertical pipe.
• When calculating e
ff
ective pipe lengths
subtract approximately 1-1/2 inch for
pipe joint - for example, a 12 inches pipe
section will add approximately 10-1/2
inches overall.
