Connecting a one piece 90 degree elbow pipe to the
combustion air inlet adaptor is required. This will
prevent debris or objects from falling into the appliance.
The exhaust vent system must vent directly to the
outside of the building and an adequate amount of
indoor combustion air must be provided for this
installation. See chapter 3.4.
Note: reduce 2.5 ft for each 90° elbow used after the
first one, reduce 1.25 ft for each 45° elbow.
A maximum of three 90-degree elbows are permitted.

systems to prevent rain from entering
the appliance, failure to do so may result
in damage to the appliance. This failure
is not covered under the manufacturer’s
warranty.
