1.
IMPORTANT
The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians. All duct work or portions thereof not in
the conditioned space should be properly insulated in
order to both conserve energy and prevent condensation
or moisture damage.
2. APPLICATION
This is a fan-assisted forced air gas furnace for outdoor
installation. A fan-assisted furnace is equipped with an
integral mechanical means to draw products of
combustion through the combustion chamber and heat
exchanger. The furnace installation must conform with
local building codes and ordinances or, in their
absence, with the National Fuel Gas Code ANSI
Z223.1 or CAN/CGA-B149.1, latest edition, and the
National Electrical Code ANSI/NFPA-7 or CSA C22.1,
latest edition. It is the personal responsibility and
obligation of the purchaser to contact a qualified
installer to assure that installation is adequate and is in
conformance with governing codes and ordinances.
3.
DUCT WORK
The unit is designed for use with or without duct work.
See Warning on Page 8. Flanges are provided for
attaching the supply and return ducts. These
instructions explain the recommended method to
installing the gas heating unit and the electrical wiring
connections and gas piping to the unit. All internal
wiring is complete.
These instructions and any instructions packaged with
any separate equipment required to make up the entire
heating system should be carefully read before
beginning the installation. Note particularly “Starting
Procedure” and any tags and/or labels attached to the
equipment.
All duct work, supply and return, must be properly sized
for the design airflow requirement of the equipment.
Air Conditioning Contractors of America (ACCA) is an
excellent guide to proper sizing.
CAUTION
During the initial firing of the burners there will probably be some amount of smoke issued to the
circulating air stream as the result of residual oil burning off of the heat exchanger tubes. This oil
is required during the forming process of the stainless steel heat exchanger tubes to facilitate the
bending. OSHA or the National Toxicology Program does not list the oil as a carcinogen. In
vapor form this may be irritating to the eyes or could cause headaches. This is a one-time
occurrence, and ventilation of the space may be required depending upon the space being
conditioned.
