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 and in general are slightly bigger.
• Minimum 12 inches vertical pipe section
required right at unit. Refer to venting chart
on page 28 for allowable horizontal runs.
• 3 inches to combustibles required above
horizontal pipe. Slope 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 per pipe
joint - for example, a 12 inches pipe sec-
tion will add approximately 10-1/2 inches
overall.
