Connectthe 3/4" OD rubber hose with the 90 ° bend to the large drain stub on the condensate trap and secure with a 3/4" clamp.
Route the hose to the drain stub on the bottom of the plastic transi- tion box. Cut off excess hose and discard. Connect the hose to the
drain stub on the transition and secure with a 3/4" clamp.
Connect the 5/8" OD rubber hose with the 90 ° bend to the right s-
tub on the vent fitting and secure with a 5/8" clamp.
Route the hose to the smaller drain stub on the condensate trap. Cut off excess hose and discard. Connect the hose to the drain
stub on the trap and secure with a 5/8" clamp.
NOTE: Route hoses to the condensate trap with no kinking or
binding for proper condensate drainage.

Downflow Installations - (Single Pipe & Direct Vent N9MP1 & N9MP2 Models) (See Figure 17)
NOTE: DO NOT make hose 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 17). Install the condensate trap/hose assembly to the furnace casing. Hook one side ofthe"cla mp ears" on the drain stub through the hole in the casing and push the con- densate trap into position. Secure with the two screws. Recon-
nect the drain hoses to the stubs on the vent fitting and the plastic transition and secure with the clamps.
Mount the condensate drain trap in a vertical position to either the right or left 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 relocated to the open set of holes in the oppo- site side panel.
