NOTE: DO NOT make connections until the hose routing and

lengths have been determined. Remove the condensate trap and drain hoses from the furnace and secure the drain hoses to the

drain stubs on the trap with the hose clamps (position the clamps as shown in Figure 8). Install the condensate trap/hose assem-

blyto the furnace casing. Hook one side ofthe"clamp ears" on the drain stub through the hole in the casing and push the condensate trap into position. Secure with the two screws. Reconnect the drain hoses to the stubs on the vent fitting and the plastic transi- tion and secure with the clamps.

Mount the condensate drain trap in a vertical position to either the left or right side of the furnace using the two screws and gasket that are provided. If needed, remove the hole plugs from the fur- nace side panel and relocate to the open set of holes in the oppo- site side panel.

NOTE: All gaskets and seals must be in place for sealed combus- tion applications.

Ensure that the vent fitting and the 90 ° elbow are securely at-

tached	to the	combustion			blower using the clamps. Note for prop-
er alignment		of	the vent	pipe through		the furnace,		the 90 ° elbow
must	be installed		with the		"UPFLOW"	lettering	on	the	90 ° elbow
facing	out.
NOTE:	The	90 ° elbow		is	approved	for use	inside		the furnace
ONLY.

Plug the upper drain stub on the vent fitting with the yellow plastic cap.

For left side venting, remove 90 ° elbow from the vent fitting by loosening the clamp on the vent fitting. Securely attach vent fitting

to combustion blower.

NOTE: For left side venting, the vent fitting MUST be installed with the airflow marking arrow pointed toward the vent pipe, with the drain stub at a 5 ° to 10 ° downward slope.

Connect the PVC vent extension pipe to the vent fitting. This pipe

has a built-in channel to assist vent condensate disposal. Align the arrow on the PVC pipe with the airflow marking arrow on

the ventfittin . See label on the PVC i efor ro erinstallation. 44001 111400
