COMBUSTION AIR SUPPLY

For indoor installation, the heater location must provide sufficient air supply for proper combustion and ventilation of the surrounding area.

The requirements for the air supply specify that the room in which a heater is installed should be provided with two permanent air supply openings; one within 12 inches of the ceiling, the other within 12 inches of the floor. These openings shall directly, or through duct, connect to outdoor air.

Pentair Water Pool and Spa, Inc. does not recommend indoor installations that do not provide combustion air from outside the building.
