OUTSIDEAIRINTAKE

Outside air is strongly recommended for all other installations as well. Failure to install intake air

may result in improper combustion as well as the unit emitting smoke during power failures.

Metal pipe, ONLY, either solid or flexible, must be used in all outside air installations.(B)

A wind shield, (C), over the termination of the outside air intake pipe or a 90 degree elbow or

bend directed away from the prevailing winds MUST be used when an outside air pipe is in-

stalled through the side of a building. Keep the outside air pipe termination at least 1 foot away

from the exhaust system termination. Keep the pipe termination clear of debris, ice & snow. In-

spect the termination on a routine basis.

When outside air is taken from an existing chimney, the exhaust system must not terminate in the

same chimney.

The air intake pipe on your stove is 2" OD. The outside air connecting pipe must be at least 2" ID

The outside air connecting pipe must be as short and free of elbows as possible, and must fit

over the air intake pipe on your stove.

rise of pipe, inside or outside the building.

VS0952_H 2/12/201020

These styles of installation are highly recommended, due to possible backpressure in the exhaust caused by

airflow around the outside of the structure, snow build-up, or power failure, etc.. These designs will improve

venting performance and provide natural draft to help evacuate smoke from the appliance in case of power

failure. Follow the same basic steps in locating your appliance, attaching the exhaust system and outside air

intake to your stove as the previous examples.
