1.
Connect PS2 tubing to switch and new sensing location.
Important:
Cut to length but insure there is a rise in the tubing to
avoid condensed flue gases from entering pressure
switch.
2.
Remove port cap on left side of inducer and connect inducer
condensate tubing. Connect other end of inducer condensate
tubing to top port on the condensate trap. Cut tubing to length, if
necessary.
3.
Install previously removed port cap onto bottom port of the
inducer. (As viewed in upflow)
4.
Connect condensate pressure switch tubing to pressure port on
the condensate trap.
Important:
Trim the PS2 pressure switch tubing to length to
ensure there is no sag or trap created.
5.
Remove port plug from rain gutter and install in new position on
opposite side of the rain gutter.
6.
Connect rain gutter condensate hose to the rain gutter and the
lower port of the condensate trap. Route rain gutter condensate
hose to the right of the inducer motor.

Furnace in Horizontal Right
Position - Top Vented
Combustion Air
Changes need to be made to the inducer orientation when installing
the upflow furnace in the horizontal right position with the combustion
air vented through the left side. Additional changes are needed for
hose routing, condensate trap location, and inducer port caps, and the
condensate plug.
The figure to the right shows the furnace as it is sent from the factory.
Use the following steps to modify the furnace for horizontal right with
left side venting of combustion air.
Important:
PS2 conversion does not apply to the S9X1 or S9B1
models.
Before proceeding, lay unit on its back to make the conversion easier.
1.
Remove all drain hoses from condensate trap.
Note:
When removing condensate hoses from the condensate trap,
hold the trap with your hand to prevent the trap from breaking.
Removing the trap before the hoses is also an option.
2.
Remove tubing from PS2 to cold header.
3.
Remove drain tubing from bottom of inducer housing.
4.
Remove rain gutter tubing from inducer outlet.
5.
Remove tubing from condensate pressure switch.
6.
Remove the screws that hold the condensate trap bracket. The
condensate trap should not be removed from the condensate trap
bracket. Remove assembly and retain for later installation.
7.
Remove the adapter located inside the condensate trap
connection on the cold header and retain for later installation.
Note:
The plastic adapter with O-rings located inside the cold header
that is held in place by the condensate trap bracket. Do not lose
this adapter. This adapter needs to be in place when the
condensate trap bracket is reattached.
