7.Upflow and Counterflow units.
For upright installations, externally mount the rubber elbow to the vent/flue coupling using a worm gear hose clamp. Secure field supplied vent/flue piping to the rubber elbow using a worm gear hose clamp. NOTE: Use of the alternate vent/flue location for upright installations, requires the drain trap be installed on the same side of the unit as the flue pipe.
8.Upflow and Counterflow units.
For horizontal installations, externally secure the field- supplied vent/flue pipe directly to the vent/flue coupling using a PVC or ABS coupling or elbow.
ALTERNATE COMBUSTION AIR INTAKE LOCATION
The alternate combustion air intake location consists of a large, unobstructed hole (alternate vent connection is aligned with the Induced Draft Blower). To use the alternate combustion air intake location, refer to the following steps, and the “Alternate Combus- tion Air Intake Location” figure.
NOTE: Counterflow unit instructions follow the upflow instructions.
1. Remove and save the four screws securing the combustion |
air intake coupling to the furnace’s top panel (upflow). |
Counterflow units. |
Remove and save the four screws securing the combustion |
air intake coupling to the basepan. Remove an additional |
three screws securing the furnace’s internal combustion |
air intake pipe to the blower deck. |
2. Remove the combustion air intake coupling and gasket from |
the top panel. |
Counterflow units. |
Remove the combustion air intake pipe from the furnace |
and cut the pipe at the basepan coupling. Save the basepan |
coupling and gasket from the blower deck coupling for use |
in the alternate location. Discard the remaining pipe. |
3. Remove plastic plug from alternate combustion air intake |
location. Relocate and install plug in standard air intake |
