FIGURE 24.
The vent terminal should be kept as close as possible to the outside wall,
but you need to allow at least 1.5" (3.8 cm) of pipe past the wall, for the
wall flange and vent terminal to mount on the pipe.
Before the vent terminal is installed, caulk (not supplied) around the
pipe on the exterior wall and install the optional wall flange. The flange
can be held to the outside wall by placing some of the caulking on the
back of the flange. The wall flange is supplied for decorative purposes
only and is not a requirement for the vent termination (if not needed by
the installer).
VERTICAL VENT THROUGH ROOF
This unit is approved for venting through the roof with the type vent
terminal that is included with the unit. A proper flashing or "BOOT" should
be used to seal the pipe where it exits the roof.
The total vent system should not exceed that which is specified, see
VENTING AND INSTALLATION, page 17.
VERTICAL VENT TERMINATION RESTRICTIONS
1. Minimum of twelve 12" (30.5 cm) above the roof or twelve 12"
(30.5 cm) above the anticipated snow level. Provide proper support
for all pipe protruding through the roof.
