NOTES:
(1)
The
horizontal run of vent pipe must
be level and
should have a 1⁄4” rise
for every one foot of run towards
the termination.
Never allow the
vent to run downward. This could cause
high temperature and may present the
possibility of a fire.
(2)
The location of the horizontal vent
termination on the exterior wall must not
be easily blocked or obstructed. Refer

When installing a vent pipe in a chase
the minimum clearance to combustibles
is 2” (51 mm).
NOTE:
Vent pipe must not be longer
than 18” (457 mm) maximum when
installing straight through exterior wall.
Maintain manufacturer’s clearances to
combustibles with venting.
Vent may extend between 6” (152 mm)
and 18” (457 mm) maximum straight
out.
When installing this unit in a corner the
maximum distance after 45˚ elbow is 9”
(228 mm).
If between 9” (229 mm) and 24” (610
mm), a 14” (356 mm) snorkel must be
