Downflow Furnace - Left Side Vented Combustion Air
Changes need to be made to the inducer orientation when installing
the downflow furnace with the combustion air vented through the
side.
The figure to the right shows the furnace as it is sent from the factory.
Use the following steps to modify the furnace for downflow with side
venting of combustion air.
Important: Right side vent outlet is not allowed because condensate
will not drain.
Before proceeding, lay unit on its back to make conversion easier.
1. Disconnect all drain tubes from condensate trap.
Note: When removing condensate hoses from the condensate trap,
hold the trap with your hand to prevent the trap from breaking.
Note: If preferred, the trap may be removed before the hoses.
2. Remove drain tubing from bottom of inducer housing.
3. Remove rain gutter tubing from inducer outlet.
4. Remove tubing from condensate pressure switch.
