Extension Kit Installation

If necessary, extension kits are available to extend the
exhaust line and air intake hose between the manifold
and the appliance. The maximum vent length is 13 feet
(4 m) with 2 bends. The bent pipe attached to the
appliance does not count toward the max limit of 2
bends.
Horizontal sections should be sloped 3º to drain
condensate. (3º equals 2/3 inch drop per foot of vent.)
The direction should be to the outside (if local codes
allow) or toward the appliance. Do not allow any low
points in the exhaust line where condensate will collect.
