Sidewall (General) Venting Information
Figures 15 and 16 show examples of horizontal termi-
nation arrangements using two 90° elbows (Rigid Vent).
NOTE:
1. A maximum of two 90° elbows are permitted.
2. A minimum of 10’ (3 m) vertical from base of unit is
required if two 90° elbows are used.
3. Minimum distance between elbows is 2’ (610 mm).
4. Determine the permitted range of horizontal ter-

Flex Venting
• Flex vent shall use the spacer springs as included
every foot to ensure proper vent operation.
• The 4” x 7” flex system may be used for all sidewall
applications and vertical venting up to 35’ (10.7 m).
• Flex shall be properly supported so there are no
sags in the system. Supports must be used at least
every 24” (610 mm) on horizontal section and every
36” (914 mm) on vertical. Wire or metal stripping
may be used to support the venting.
• For 4” x 7” flex, the 7” flex has an outside diameter
of 7¹⁄₂” (191 mm) and if installed in a chase the in-
side diameter of the chase should be 9¹⁄₂” (241 mm)
minimum.
