Field Supplied Drain
Drain the furnace and air conditioning coil if applicable,
in compliance with code requirements. In horizontal or
counterflow installations, a field installed rubber coupling will
allow the drain trap to be removed for cleaning. The drain
trap must be primed before initial furnace start up. When an
air conditioning coil drain is connected to the field supplied
furnace drain, it must be vented by an open tee installed at a
height no higher than the bottom of the furnace collector box
to prevent air conditioning condensate from backing up into
the furnace if the common drain was blocked.
Upflow Model Installed Vertically
The trap and factory installed hoses remain as shipped.
The furnace drain may exit either the right or left side of the
furnace cabinet. Both sides of the cabinet have two .875”
diameter holes which can be used interchangeably for drain
and low voltage wiring purposes. If a higher drain exit is
needed, a .875” diameter hole may be added in the area
shown in Figure 21. Any unused cabinet opening must be
sealed. Do not allow drain hose to sag or trap water.
