1.
FURNACE AND COIL
The coil MUST BE installed downstream (in the outlet air)
of the furnace. The coil apex can face into or away from the
direction of the airflow, depending on horizontal left or right
application.
These coils fit the 171h'', 21", and 241h'' "width furnaces

pump or cooling combinations approved for these coils.

a coil is part of the total system installation, use the
Installer's Guide packaged with the furnaces, and outdoor
sections, and comfort control for physically installing those
components.
2.
It
is recommended that the outline drawing be stud-
ied and dimensions properly noted and checked against
selected installation site. By noting in advance proper
clearance allowances for installation and possible future
