VENT TERMINATION

Horizontal vents should pass through
the exterior wall. Figure 8 shows
a standard horizontal vent detail.
Terminate the vent approximately 8" or
more from the wall.
Exterior vent pipe greater than 24"
should be insulated with ½" insulation
to prevent moisture from freezing within
the pipe and accumulating.
Size the exhaust pipe as specifi ed in
Table 4 - Direct and Non-Direct Vent
Lengths. This table lists the maximum
allowable length of pipe with respect to
the number of 90° elbows used. For the
purposes of this calculation, one 90°
elbow is equivalent to two 45° elbows.
Avoid locating the terminal in locations
where dripping condensate may cause
problems such as sidewalks, patios,
above planters, near windows where
exhaust gases may cause fogging, etc.
Avoid locating the termination too close
to shrubs and other vegetation. The
condensate may stunt or kill them.
