For applications where vertical venting is not possible, the only
approved method of horizontal venting is the use of an auxiliary power
vent. Approved power venters are Fields Controls Model SWG-4Y or
Tjernlund Model GPAK-JT. Follow all application and installation details
provided by the manufacturer of the power vent. This unit may be hori-
zontally vented using 4” (10.2 cm) diameter pipe with a minimum length
of 4.5 feet (1.37 m) and a maximum length of 34.5 feet (10.82 m) with
up to 4 elbows.

checking for proper fit support and slope. Piping should be sup-
ported with pipe hangers to prevent sagging. The maximum spac-
ing between hangers is 5 feet (1.5 m).
