INSTALLATION / FREESTANDING UNIT / DETAIL
The flue vent exit shall be located not less than 48” from any opening through which exhaust could
enter the building, (i.e. windows and doors), and not less than 24” from adjacent public walkways. It
shall be arranged so that flue gases are not directed in such a way as to pose a health hazard, overheat
combustible structures or enter any building. Do not terminate the exhaust flue pipe in an attic,
garage, carport or any enclosed or semi-enclosed area, under a porch or sun deck, or near shrubs or
combustibles stored near the outlet.
