Venting System Length Calculations

The Total Equivalent Vent Length (TEVL) for 

EACH 

combustion air or vent pipe equals the length of the venting system, plus the equivalent length of

elbows used in the venting system from Deductions from Maximum Equivalent Vent Length - Ft. (M) Table.
Standard vent terminations or factory accessory concentric vent terminations count for zero deduction.
See vent system manufacturer’s data for equivalent lengths of flexible vent pipe or other termination systems. 

DO NOT ASSUME

 that one foot of

flexible vent pipe equals one foot of straight PVC/ABS DWV vent pipe. 
Compare the Total Equivalent Vent Length to the Maximum Equivalent Vent Lengths in Maximum Equivalent Vent Length Table.

Example 1

A direct-vent 60,000 BTUH furnace installed at 2100 ft. (640M). Venting system includes 

FOR EACH PIPE:

70 feet (22 M) of

 

vent pipe, 65 feet (20 M) of combustion air inlet pipe, (3) 90º long-radius elbows, (2) 45º long-radius elbows, and a factory accessory

concentric vent kit.
Can this application use 2” (50 mm ND) PVC/ABS DWV vent piping?

Example 2

A direct-vent 60,000 BTUH furnace installed at 2100 ft. (640M). Venting system includes 

FOR EACH PIPE:

100 feet (30 M) of

 

vent pipe, 95 feet (29 M) of combustion air inlet pipe, (3) 90º long-radius elbows, and a polypropylene concentric vent kit. Also

includes 20 feet (6.1 M) of flexible polypropylene vent pipe, included within the 100 feet (30 M) of vent pipe.
VERIFY FROM POLYPROPYLENE VENT MANUFACTURER’S INSTRUCTIONS for the multiplier correction for flexible vent pipe.
Can this application use 60mm o.d. (2”) polypropylene vent piping? If not, what size piping can be used?
