1.
Connect PS2 tubing to switch and new sensing location.
Important:
Trim the condensate pressure switch tubing to length to
ensure there is no sag or trap created.
2.
Remove port cap on left 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.
4.
Connect condensate pressure switch tubing to pressure port on
the condensate trap.
Important:
Trim the condensate pressure switch tubing to
length to ensure there is no sag or trap created
5.
Connect rain gutter condensate hose to the rain gutter and the
lower port of the condensate trap.

Upflow Furnace in Horizontal Left
Position — Side Vented Combustion Air
Changes do not need to be made to the inducer orientation when
installing the upflow furnace in the horizontal left position with the
combustion air vented through the top. Changes are needed for hose
routing, condensate trap orientation, and inducer port caps.
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 left with
top venting of combustion air.
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.
Note:
There is a 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.
