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 5). Install the condensate trap/hose assembly to
the furnace casing. Hook one side of the "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
441 06 1039 oo
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 furnace
side panel and relocate to the open set of holes in the opposite side
panel.
