• Side of the building with prevailing winter winds.
• Close to plants or trees.
• In areas where people or animals can accidentally
touch louvered exhaust openings.

The Recess box should be installed so the discharge
vent maintains the minimum allowable clearances as
required by the local authority. Where no local require-
ment exists, maintain the following minimum suggested
clearances from builing openings as shown in Fig. 15.
