used when installed on combustible materials and wood flooring.
Special base is not required when this furnace is installed on
manufacturer’s Coil Assembly Part No. CD5 or CK5, or when Coil
Box Part No. KCAKC is used.
These furnaces are shipped with the following materials to assist in
proper furnace installation. These materials are shipped in the main
blower compartment.
These furnaces are shipped with the drain and pressure tubes
connected for UPFLOW applications. Minor modifications are
required when used in DOWNFLOW, HORIZONTAL RIGHT, or
HORIZONTAL LEFT (supply-air discharge direction) applica-
tions as shown in Fig. 1. See details in Applications section.
This furnace must be installed with a direct-vent (combustion air
and flue) system and a factory accessory termination kit. In a
direct-vent system, all air for combustion is taken directly from the
outside atmosphere and all flue products are discharged to the
outside atmosphere. See furnace and factory accessory termination
kit instructions for proper installation.

1. All tubing must be connected securely and routed to avoid kinks and traps.
2. Pressure tubing must always slope away from pressure switch to collector box connection as shown.
3. HORIZONTAL-LEFT installations require the collector box pressure tube to be relocated between the inducer housing and the blower shelf to
prevent a trap.Refer to the Installation Instructions for further details.
