Table 4

Determining required vent length:

1.Determine the total length of straight vent pipe (in feet) required.

2.Add 5 feet (1.5 m) of venting for every 90° elbow.

3.Add 2 ½ feet (.7 m) of venting for every 45° elbow.

4.Total vent length cannot exceed “Max. Vent Length” in Table 4.

Example of Total Vent Length for EF100T199 with a power vented installation:

A 3 inch (7.6 cm) venting system has a total of six 90-degree elbows and a total straight pipe length of 55 feet (16.5 m). Equivalent vent length for elbows: 6 x 5 feet (1.5 m) = 30 feet (9 m).

Total equivalent vent distance = 55 feet (16.5 m) + 30 feet (9 m) = 85 feet (25.5 m) total equivalent vent length. This is below the maximum allowed distance of 100 feet (30 m) for this model using 3 inch (7.6 cm) vent.

NOTICE

Do not include the 3 inch (7.6 cm) condensate elbow or vent terminals in determining maximum vent length.
