General Information
Description
The duct furnace design is certified by ETL for use with
natural and LP (propane) gases. ANSI and NFPA Standards
as well as Canadian installation codes referred to in this
manual are the ones that were applicable at the time that
the design was certified. In addition, the duct furnace may
be installed on the downstream side of a cooling coil,
without need of a bypass duct.
If the unit is to be installed at an altitude exceeding
2,000 feet (610 m) above sea level, derate the input by
4 percent for each 1,000 foot (305 m) rise above sea level.
Special orifices are required for installations above
2,000 feet (610 m).
When units are installed in Canada, any reference to
derations at altitudes in excess of 2000 feet (610 m) are to
be ignored. At altitudes of 2000 to 4500 feet (610 to
1372 m), the units must be orificed to 90 percent of the
normal altitude rating, and be so marked in accordance
with the ETL certification.
General Safety Information
Important: This product must be installed by a licensed
plumber or gas fitter when installed within
the Commonwealth of Massachusetts.
WARNING
Safety Alert!
You MUST follow all recommendations below. Failure
to do so could result in death or serious injury.
•
Installation must be made in accordance with
local codes, or in absence of local codes with the
latest edition of ANSI Standard Z223.1 (N.F .P .A.
No. 54) National Fuel Gas Code.
All of the ANSI and NFPA Standards referred to
in these installation instructions are those that
were applicable at the time the design of this
appliance was certified. The ANSI Standards are
available from the American National Standards
Institute, INC.,11 West 42nd Street, New York,
NY ., 10036 or www.ansi.org. The NFPA
Standards are available from the National Fire
Protection Association, Batterymarch Park,
Quincy, MA 02269. These duct furnaces are
designed for use in airplane hangars when
installed in accordance with current ANSI/NFPA
No. 409 and in public garages when installed in
accordance with current NFPA No. 88A and
NFPA No. 88B.
If installed in Canada, the installation must
conform with local building codes, or in absence
of local building codes, with CGA-B149.1
"Installation Codes for Natural Gas Burning
GMND-SVX01B-EN
Appliances and Equipment" or CGA-B149.2
"Installation Codes for Propane Gas Burning
Appliances and Equipment" . These duct furnaces
have been designed and certified to comply with
CGA 2.6. Also see sections on installation in
"Aircraft Hangers, " p. 12
p.
12.
•
Do not alter the duct furnace in any way or
damage to the unit and/or severe personal injury
or death could occur!
•
Turn off the gas supply and disconnect all
electric power, including remote disconnects
before servicing unit. Follow proper lockout/
tagout procedures to ensure the power can not
be inadvertently energized and the gas can not
be inadvertently turned on. Failure to turn off
gas or disconnect power before servicing could
result in death or serious injury.
•
Follow installation instructions CAREFULLY to
avoid creating unsafe conditions. All wiring
should be done and checked by a qualified
electrician, using copper wire only. All external
wiring must conform to applicable local codes
and to the latest edition of the National
Electrical Code ANSI/NFPA No. 70.
•
All gas connections should be made and leak-
tested by a suitably qualified individual, per
instructions in this manual. Also follow
procedures listed in
p.
30.
•
Use only the fuel for which the duct furnace is
designed (see rating plate). Using LP gas in a
heater that requires natural gas, or vice versa,
will create the risk of gas leaks, carbon
monoxide poisoning and explosion.
Important: Do not attempt to convert the furnace
for use with a fuel other than the one
intended. Such conversion is
dangerous, as it could create the risks
listed previously.
•
Make certain that the power source conforms to
the electrical requirements of the furnace.
•
All field-installed wiring must be completed by
qualified personnel. All field-installed wiring
must comply with NEC and applicable local
codes. Failure to follow this instruction could
result in death or serious injuries.
•
Special attention must be given to any
grounding information pertaining to this duct
furnace. To prevent the risk of electrocution, the
furnace must be securely and adequately
grounded. This should be accomplished by
connecting a grounded conductor between the
service panel and the furnace. To ensure a proper
