NOTES:
(1) The horizontal run of vent pipe must be
level and should have a 1⁄4 inch 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 to
“Initial Installation - Vent Termination
Restrictions” section.
(3) 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 inches (152
mm) and 18 inches (457 mm) maximum
straight out.
When installing this unit in a corner the
maximum distance after 45˚ elbow is 9
inches (228 mm).
If between 9 inches (229 mm) and 24
inches (610 mm), a 14 inches (356 mm)
snorkel must be used.
