side panel and relocated to the open set of holes in the opposite side
panel.
NOTE: All gaskets and seals must be in place for sealed combus-
tion applications.
For both right and left side vent, remove the 90° street elbow from
the vent fitting by loosening the clamp on the vent fitting.
Ensure that the vent fitting is securely attached to the combustion
blower using the rubber coupling and clamps.
This configuration allows right side venting from the furnace. If the
left side venting is required, the combustion blower must be relo-
cated on the plastic transition box. Remove the four(4) screws that
secure the blower to the transition. Rotate the blower 180° and se-
cure with the four(4) screws. Use caution to not over tighten the
screws to prevent stripping out of the plastic mounting holes.
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.
Plug the upper drain stub on the vent fitting with the yellow plastic
cap.
Remove the pressure switch hose from the upper stub on the plastic
transition box.
Relocate the plastic caps on the stubs of the plastic transition box
from the lower stubs to the upper stubs and secure tightly with the
clamps.
Route the pressure switch hose to the lower stub on the plastic tran-
sition box. Cut off excess hose and discard. Connect the pressure
switch hose to the lower stub on the plastic transition box. NOTE:
Failure to correctly install the pressure switch hose to the transition
box can adversely affect the safety control operation.
