NOTE: A heat loss calculation should be performed to
properly determine the required furnace BTU size for the
structure. Also, the duct must be properly designed and in-
stalled for proper airflow. Existing ductwork must be in-
spected for proper size and to make sure that it is properly
sealed. Proper airflow is necessary for both user comfort
and equipment performance.
Before opening the furnace carton, verify that the data
tags on the carton specify the furnace model number
that was ordered from the distributor and are correct
for the installation. If not, return the unit without open-
ing the carton. If the model number is correct, open
the carton and verify that the furnace rating label
specifies the same furnace model number that is
specified on the carton label. If the model numbers do
not match, return the furnace to the distributor.
IMPORTANT: Proper application, installation and mainte-
nance of this furnace and system is a must if consumers
are to receive the full benefits for which they have paid.
The (-)97V series furnaces are design-certified by CSA for
use with natural and propane gases as follows:
