Horizontal Installation Wall Penetrations - FULTON PulseHW Series Installation, Operation And Maintenance Manual

25. Horizontal Installation Wall Penetrations

a) Select the point of penetration where a minimum of 1/4" per foot upward pitch can be
maintained.
b) When penetrating a non-combustible wall, the hole through the wall must be large
enough to maintain the pitch of the vent and provide sealing. Use adhesive material to
seal around the vent on both sides of the wall. When penetrating a combustible wall, a
wall thimble must be used. See next page Figure 14 for installation instructions. Minimum
wall thickness through which vent system may be installed is 3 1/4". Maximum wall
thickness through which vent system may be installed is 20 inches.
