Venting Considerations—Vertical Takeo
ff
*
Notes—ALL venting considerations
• Dimensions of venting are based on us-
ing Dura-Vent elbows. Elbow curve radius
dimensions will vary when using other
brands. In general, other brands have
slightly bigger radius.
• Minimum 24 inches vertical pipe section
required right at unit. Refer to venting chart
on page 30 for allowable horizontal runs.
• 3 inches clearance to combustibles re-
quired above horizontal pipe. Slope hori-
zontal pipe upwards 1/4 inch per foot. 1
inch clearance required around sides and
bottom of horizontal pipe and around verti-
cal pipe.
• When calculating e
ff
ective pipe lengths
subtract approximately 1-1/2 inch for pipe
joint - for example, a 12 inches pipe sec-
tion will add approximately 10-1/2 inches
overall.
