LOCATION

I. GENERAL
This furnace must:
• be installed so the electrical components are protected from

water.

• not be installed directly on any combustible material other than

wood flooring (refer to INTRODUCTION).

• be located as close to the chimney/vent and attached to an air

distribution system. Refer to Air Ducts section.

• be provided ample space for servicing and cleaning. Always

comply with minimum fire protection clearances shown on the

furnace rating plate.

CAUTION: Do not install furnace in a corrosive or

contaminated atmosphere. Make sure all combustion and

circulating air requirements are met, in addition to all

local codes and ordinances.

CAUTION: Do not operate the furnace during construc-

tion. If the furnace is required, use clean outside air free

of chlorine and fluorine compounds for combustion and

ventilation. These compounds form acids that corrode the

heat exchangers and vent system. These compounds are

found in paneling and dry wall adhesives, paints, thin-

ners, masonry cleaning materials, and other solvents.

WARNING: DO NOT install the furnace on its back.

Safety control operation will not perform properly. A

failure to follow this warning can cause a fire, personal

injury, or death.

II. LOCATION RELATIVE TO COOLING EQUIPMENT

The cooling coil must be installed parallel with, or on the

downstream side of the unit to avoid condensation in the heat

exchangers. When installed parallel with the furnace, dampers or
