See Figure 1 for overall dimensions to determine the re- quired clearances in hallways, doorways, stairs, etc. to allow the furnace to be moved to the installation point. The furnace must be in- stalled so that all electrical components are protected from water.

Minimum clearances to combustible materials are listed in Table 4. Access for positioning and servicing must be considered when locating the unit.

This furnace is certified for use on wood flooring. The furnace must be installed on a solid surface and must be level front-to-back and side-to-side. This furnace must not be installed directly on carpeting, tile, or any com-

bustible material other than wood flooring. The furnace may be installed on combustible floor- ing when installed on a Nordyne duct connec- tor (see Table 5).

The ductwork within 3 feet of the furnaces without the A/C coil box must be installed such that surfaces are at least 1/4" from combustible materials.

When installed in a residential garage, the fur- nace must be positioned so the burners and the source of the ignition are located no less than 18 inches above the floor and protected from physical damage by vehicles.

CIRCULATING AIR SUPPLY

!WARNING:

Products of combustion must not be allowed to enter the return air openings of the furnace or the circulating air supply. Failure to prevent products of combustion from being circulated into the living space can create potentially hazardous conditions including carbon monoxide poisoning that could result in personal injury or death.

The floor or platform on which the furnace is mounted must provide sound physical support of the furnace with no gaps, cracks, or sagging between the furnace and the floor or platform.

The circulating air ductwork must not be connected to any other heat producing device such as a fireplace insert, stove, etc.

GENERAL

Plenums and air ducts must be installed in accordance with the Standard for the Installa- tion of Air Conditioning and Ventilating Systems (NFPA No. 90A) or the Standard for the Instal- lation of Warm Air Heating and Air Conditioning Systems (NFPA No. 90B).
