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.  This furnace may be installed on a combustible floor when utilizing either the 
No. 70 counterflow floor base or CE111S / CE211T 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. 
 
This furnace is ETL listed for closet, alcove or free standing applications.  All 
applications must comply with the requirements of this manual.
