garages in accordance with ANSI/NFPA No. 88A (latest edition), Stan-
dard for Parking Structures; and for repair garages in accordance with
ANSI/NFPA No. 88B (latest edition), Standard for Repair Garages.
ANSI/NFPA-88 (latest edition) specifies overhead heaters must be in-
stalled at least eight feet above the floor. In Canada, installations in
aircraft hangars should be in accordance with the requirements of the
enforcing authorities, and in public garages in accordance with CAN/
CGA B149 codes.
ANSI/NFPA 409 (latest edition) specifies a clearance of ten feet to the
bottom of the heater from the highest surface of the top of the wing or
engine enclosure of whatever aircraft would be the highest to be housed
in the hangar, and a minimum clearance of eight feet from the floor in
other sections of aircraft hangars, such as the offices, and shops which
communicate with areas used for servicing or storage. The heaters must
be located so as to be protected from damage by aircraft or other ob-
jects such as cranes and movable scaffolding. In addition, the heaters
must be located so as to be accessible for servicing, adjustment, etc.
2. Warranty
Refer to the limited warranty information on the warranty form in the
"Owner's Envelope".
Warranty is void if ...
a. Wiring is not in accordance with the diagram furnished with the
heater.
b. The unit is installed without proper clearance to combustible
materials.
c. The heater is connected to a duct system or if the air delivery
system is modified.
3. Uncrating and Preparation
This unit was test operated and inspected at the factory prior to crating
and was in operating condition. If the heater has incurred any damage
in shipment, document the damage with the transporting agency and
immediately contact your Reznor Distributor.
Check the rating plate for the gas specifications and electrical charac-
teristics of the heater to be sure that they are compatible with the gas
and electric supplies at the installation site.
Read this booklet and become familiar with the installation require-
ments of your particular heater. If you do not have knowledge of local
requirements, check with the local gas company or any other local agen-
cies who might have requirements concerning this installation.
Before beginning, make preparations for necessary supplies, tools, and
manpower. If the installation includes optional vertical louvers or a
downturn nozzle, install these options before the heater is suspended.
Follow the instructions included in the option package; option pack-
ages are shipped separately.
If the heater is to be operated at an altitude above 2000 ft (610M), a
pressure adjustment may be required. See Paragraph 4.
Concentric Adapter Kits for combustion air and
venting (Option CC2 or Option CC6)
The concentric adapter is a required component in the installation of
all Model SFT heaters. The kit is shipped in a separate carton. Be sure
that the concentric adapter carton is at the installation site. A horizontal
vent/combustion air kit including the concentric adapter is identified
as Option CC6. A vertical vent/combustion air kit including the con-
centric adapter is identified as Option CC2. See the parts lists in Para-
graph 9.
GENERAL (Cont'd)
These separated combustion units are designed and manufactured in
accordance with the ANSI definition of separated combustion. That
definition reads, "Separated Combustion System Appliance: A system
consisting of an appliance and a vent cap(s) supplied by the manufac-
turer, and (1) combustion air connections between the appliance and
the outside atmosphere, and (2) flue gas connections between the ap-
pliance and vent cap, of a type(s) specified by the manufacturer but
supplied by the installer, constructed so that, when installed in accor-
dance with the manufacturer's instructions, air for combustion is ob-
tained from the outside atmosphere and flue gases are discharged to
the outside atmosphere."
Separated combustion units are designed to separate the air for com-
bustion and the flue products from the environment of the building in
which the unit is installed. Separated combustion appliances are rec-
ommended for use in dust laden and some corrosive fume environ-
ments or in buildings with negative pressure (up to .15" w.c.). As the
definition states, all separated combustion, power-vented equipment
must be equipped with both combustion air and exhaust piping to the
outdoors.
WARNING: Model SFT separated combustion
units are not designed or approved for use in
atmospheres containing flammable vapors or
combustible dust. See Hazard Levels, below.
WARNING: Should overheating occur or the gas
supply fail to shut off, shut off the manual gas
valve to the appliance before shutting off the
electrical supply.
WARNING: Do not use this appliance if any part
has been under water. Immediately call a
qualified service technician to inspect the
appliance and replace any gas control which has
been under water.
HAZARD INTENSITY LEVELS
1. DANGER: Failure to comply will result in severe personal in-
jury or death and/or property damage.
2. WARNING: Failure to comply could result in severe personal
injury or death and/or property damage.
3. CAUTION: Failure to comply could result in minor personal
injury and/or property damage.
1. Installation Codes
These units must be installed in accordance with local building codes.
In the absence of local codes, in the United States, the unit must be
installed in accordance with the National Fuel Gas Code ANSI Z223.1a
(latest edition). A Canadian installation must be in accordance with the
CAN/CGA B149.1 and B149.2 Installation Code for Gas Burning Ap-
pliances and Equipment. These codes are available from CSA Infor-
mation Services, 1-800-463-6727. Local authorities having jurisdic-
tion should be consulted before installation is made to verify local codes
and installation procedure requirements.
Special Commercial Installations (Aircraft
Hangars/Repair Garages/Parking Garages)
Installations in aircraft hangars should be in accordance with ANSI/
NFPA No. 409 (latest edition), Standard for Aircraft Hangars; in public
