Downflow Installation

The furnace must not be installed directly on carpeting, 

tile,  or  any  combustible  material  other  than  wood 

flooring.

 To install the furnace on combustible flooring, 

a special sub-base is required.

 wARNING:

Failure to install the downflow sub-base kit may 
result in fire, property damage or personal injury.

 wARNING:

The downflow sub-base kit must not be installed 
directly on carpeting, tile, or any combustible 
material  other  than  wood  flooring.  Failure  to 
comply may result in fire, property damage or 
personal injury.

Downflow sub-base kits are factory supplied accessories 

and are listed according to the cabinet letter of the furnace. 

For ‘A’ size cabinets use Sub-Base kit #902974 only. For 

‘B’, ‘C’, and ‘D’ size cabinets use Kit #904911. 

please 

follow the instructions provided with the kit

.

A downflow sub-base kit is not necessary if the furnace 

is installed on a factory or site-built cased air conditioning 

coil. However, the plenum attached to the coil casing 

must be installed so that its surfaces are at least 1” from 

combustible construction.

Installation on a Concrete Slab

1. Create an opening in the floor according to the 

dimensions in Table 1.

2. Position the plenum and the furnace as shown in  

Figure 9.
