these instructions on page 19.
6. Always install the Furnace to operate within the
Furnace's intended temperature-rise range with a
duct system which has an external static pressure
within the allowable range, as specified on the unit
rating plate. Airflow with temperature rise for cfm
versus static is shown in the Service Facts accom-
panying this Furnace.
7. When a Furnace is installed so that supply ducts
carry air circulated by the Furnace to areas outside
the space containing the Furnace, the return air
shall also be handled by a duct(s) sealed to the Fur-
