23. Connect PS2 tubing to switch and sensing location.
IImmppoorrttaanntt:: Trim the condensate pressure switch
tubing to length to ensure there is no sag or
trap created.
24. Remove port cap at bottom 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.
25. Install previously removed port cap onto bottom
port of the inducer. (As viewed in upflow)
26. Connect condensate pressure switch tubing to
pressure port on the condensate trap.
IImmppoorrttaanntt:: Trim the condensate pressure switch
tubing to length to ensure there is no
sag or trap created.
27. Remove port plug from rain gutter and install in
new position on opposite side of the rain gutter.
28. Connect rain gutter condensate hose to the rain
gutter and the lower port of the condensate trap.
Cut to length, if necessary.
Upflow Furnace in Horizontal
Left Position - Top Vented
Combustion Air
Changes 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
side. Additional changes are needed for hose routing,
condensate trap orientation, and inducer hoses.
The figure to the top right shows the furnace as it is
sent from the factory.
Use the following steps to modify the furnace for
horizontal left with side venting of combustion air.
Before proceeding, lay unit on its back to make the
conversion easier.
1. Remove all drain hoses from condensate trap.
NNoottee:: 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.
NNoottee:: 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.
