IV. GENERAL INSTALLATION

A.FURNACE LOCATION

1.For best performance, locate the furnace so that it is centralized with respect to the duct system.

2.The furnace installation is only intended for free air return through the furnace door louvers. DO NOT connect a ducted return air system directly to the furnace. An improper return air installation may create a hazard and damage equipment, as well as void all warranties.

3.Model CMA3 furnace may be installed on a combustible floor when utilizing either the No. 70 counterflow floor base or CE113S / CE213T coil cabinet for below the floor duct systems, or the cottage base for floor level air distribution. See Figure 1A for description of Combustible Floor Base and Figure 1C for Cottage Base.

4.Model CMC1 furnace is designed to be installed directly on a combustible floor and is not required to be installed on a base.

This furnace is ETL listed for closet, alcove or free standing applications. All applications must comply with the requirements of this manual.

Combustible Floor Base Model: 70-BASE

For CMA3 models only.
