Relocate the plastic caps and clamps on the condensate drain trap
from the vertical drain stub to the horizontal drain stubs. Secure the
clamps tightly to prevent condensate leakage.
Mount the condensate drain trap in a vertical position to the left side
of the furnace using the two screws and gasket that are provided.
Note: The condensate trap will be located under the furnace in a ver-
tical position when the furnace is placed horizontally on the left side.
If needed, remove the hole plugs from the furnace side panel and
relocate to the open set of holes in the opposite side panel. Drill two
7
/ ² diameter holes in the casing using the condensate trap as the
64
template.
Connect the vent fitting and the 90° elbow to the combustion blower
using the rubber coupling and clamps.
NOTE: The vent fitting MUST be installed with the airflow marking
arrow pointed toward the vent pipe, with the drain stub at a 20 to 30°
downward slope.
