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).
