NOTE: ELEC / ELEC Models: Units and ductwork are approved for zero clearance to combustible material when equipped with electric heaters.

GAS / ELEC Models: A 1” clearance must be provided between any combustible material and the supply air ductwork for a distance of 3 feet from the unit.

The products of combustion must not be allowed to accumulate within a confined space and recirculate.

Locate unit so that the vent air outlet hood is at least:

•Three (3) feet above any force air inlet located within 10 horizontal feet (excluding those integral to the unit).

•Four (4) feet below, four horizontal feet from, or one foot above any door or gravity air inlet into the building.

•Four (4) feet from electric and gas meters, regulators and relief equipment.
