General Information - Rheem 801T Series Installation Instructions Manual

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 installed for proper air-
flow . Existing ductwork must be inspected 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 or-
dered from the distributor and are correct for the installation.
If not, return the unit without opening 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 maintenance of
this furnace and system is a must if consumers are to receive the
full benefits for which they have paid .

GENERAL INFORMATION

The 80% single stage constant torque series furnaces are design
certified by CSA for use with natural and propane gases as follows:
As a Category I furnace, it may be vented vertically with type
B-1 vent pipe and also may be common vented as described
in these instructions .
This furnace should be installed in accordance with the American
National Standard Z223 .1 - latest edition booklet entitled "National
Fuel Gas Code" (NFPA 54), and the requirements or codes of
the local utility or other authority having jurisdiction including local
plumbing or waste water codes .
With the introduction of higher efficiency furnaces, special atten-
tion must be paid to the venting system . Only listed venting sys-
tems may be used as stated in the installation instructions and the
National Fuel Gas Code, ANSI Z223.1 (NFPA 54),. Since furnace
technology and venting requirements are changing, awareness of
local, state, and federal codes and industry changes is imperative .
