NOTE:
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.
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.
Application of this furnace should be indoors with special
attention given to vent sizing and material, gas input rate, air
temperature rise, unit leveling, and unit sizing. Improper
installation or misapplication of furnace can require excessive
servicing or cause premature component failure.
