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 below 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 drain tubing from bottom of inducer
housing.
3. Remove rain gutter tubing from inducer outlet.
4. Remove tubing from condensate pressure switch.
5. 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.
6. Loosen hose clamp and remove 45 degree adapter.
If the rubber boot pulls out of the inducer opening,
remove from the adapter and reinstall onto the
inducer. Remove the elbow and discard.
7. Remove three inducer screws.
8. Rotate the inducer so that the outlet is pointing
vertically.
9. Use the three screws to reattach the inducer to the
cold header to 30 in.-lbs. Do not overtighten.
