INSTALLATION
This furnace is a true multi-position unit, in that it will
function in an upflow, downflow or horizontal configura-
tion to the left or the right. Only a few modifications are
required during installation to change from one position
to another. The unit is shipped in the upflow configura-
tion and instructions as to how to change to the other
positions are included in this manual.
The unit requires a 120/240 - 208 VAC power supply to
the control panel, thermostat hook-up as shown on the
wiring diagram.

floor, in a crawl space for example, it is recommended to
install the unit on a cement base 2.5 cm to 5.0 cm (1” to
2”) thick.
In addition, the heater should also be located close to the
center of the air distribution system.
