Enclosure Installation

Air for combustion and ventilation must not be supplied from
the occupied spaces of the manufactured (mobile) home.
IMPORTANT: The opening that provides outside air to your
water heater must have a minimum free area of 20 square
inches. Also, ensure that your installation complies with all
applicable code requirements.
The following methods may be used to provide sufficient
combustion and ventilation air to the water heater when it is
installed in the enclosure.
Method I (Figure 15)
Provide a single air opening in the exterior door of the
enclosure. The opening must have a minimum free area of
20 square inches. The bottom of the opening must be within
6 inches from the bottom edge of the door. Cover the opening
with 1/4 inch wire mesh screen or louvers.
Method II (Figure 16)
For enclosures with a solid exterior door, provide an air opening
in the floor. The opening must have a minimum diameter of 5
inches (20 square inches minimum free area) and be covered
with 1/4-inch wire mesh screen.
