Condensate Trap - Horizontal Orientation.
When the furnace is installed in the horizontal right position, the
condensate trap will be initially located at the bottom of the collector
box, as received from the factory. See the top image in Fig. 10. When the
furnace is installed in the horizontal left position, the condensate trap
will be initially located at the top of the collector box, as received from
the factory. See the top image in Fig. 11. In both cases the trap must be
repositioned on the collector box for proper condensate drainage. See the
bottom images in Fig. 10 and Fig. 11.
A field-supplied, accessory Horizontal Installation Kit (trap grommet) is
required for all direct-vent horizontal installations (only). The kit
contains a rubber casing grommet designed to seal between the furnace
casing and the condensate trap. See Fig. 12.
