UNIT WITH ECONOMIZER RAIN HOOD

1Units may be installed on combustible floors made from wood or class A, B or C roof covering material (Applicable in the U.S.A. only).

2Units must be installed outdoors. Overhanging structures or shrubs should not obstruct the outdoor coil nor the fan outlet.

NOTE: 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 forced air inlet located within 10 horizontal feet (excluding those integral to the unit).

∙Four (4) feet below, 4 horizontal feet from, or 1 foot above any door or gravity air inlet into the building.

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