be
vented vertically through the roof
through
8” (20.3 cm) round metal/
aluminum
.

The size of the vent should be uniform.
•
If venting vertically, do not use more than
three 90° elbows. Do not install two
elbows
together.
•
Make sure there is a minimum of
24”
(61
•
of straight vent between the elbows if
more than one elbow is used.
•
The length of vent system and number
of
elbows should be kept to a minimum
to
provide efficient performance.
•
The vent system must have a damper.
If
roof or wall cap has a damper,
DO NOT
use
damper (if supplied) on top of the
range
