16 Johnson Controls Ducted Systems
Note: Dimensions are those required in Standard ASTM D-3311.
Example:
An 80,000 BTUH furnace requires 32 ft of pipe and five 90º elbows.
Using 2 in. pipe and standard elbows, the total equivalent length is:
This exceeds the 65 ft maximum equivalent length of 2 in. pipe allowed
for that model and is
not acceptable.
By using sweep elbows, the total equivalent length is:
This is less than the 65 ft maximum equivalent length of 2 in. pipe
allowed for that model and is acceptable.
Alternatively, using 3 in. pipe and standard elbows, the total equivalent
length is:
This is less than the 90 ft maximum equivalent length of 3 in. pipe
allowed for that model and is acceptable.

Total = 67 equivalent ft of 2 in. pipe
32 ft of 2 in. pipe = 32 equivalent ft
5 - 90º sweep 2 in. elbows = (5 x 5) = 25 equivalent ft
Total = 57 equivalent ft of 2 in. pipe
32 ft of 3 in. pipe = 32 equivalent ft
5 - 90º standard 3 in. elbows = (5 x 7) = 35 equivalent ft

Table 8: Combustion Air Intake and Vent Connection Size at Furnace
(All Models)
FURNACE VENT CONNECTION SIZES
Furnace Input All
Intake Pipe Size 2 in. (5.1 cm)
Vent Pipe Size 2 in. (5.1 cm)
IMPORTANT: Furnace vent pipe connections are sized for 2 in.
(5.1 cm) pipe. Any pipe size change must be made outside the fur-
nace casing in a vertical pipe section to allow proper drainage of con-
densate. An offset using two 45º (degree) elbows is required for
plenum clearance when the vent is increased to 3 in. (7.6 cm).
