Gas Supply Notes:
Before assembly and connection check gas supply.
A. The type of gas for which the unit is equipped is stamped
on the data plate located behind the lower front panel.
Connect a unit stamped “NAT” only to natural gas;
connect one stamped “PRO” only to propane gas.
B. If it is a new installation have the gas authorities check
meter size and piping to assure that the unit is supplied
with the necessary amount of gas pressure required to
operate the UNIT.
C. If it is additional or replacement equipment have gas
authorities check pressure to make certain that existing
meter and piping will supply fuel to the unit with not
more than 1/2” water column pressure drop.
NOTE: When checking gas pressure be sure that all other
equipment on the same gas line is on. A pressure regulator
is not supplied as standard equipment with US Range Heavy
Duty Equipment, however a 1-1/4” pressure regulator is sold
as an option with the original purchase. If you would like to
purchase a regulator after original purchase contact your
equipment dealer. The installation must conform with the
national Fuel Gas Code ANSI Z 223.1 -1988 or latest edition,
NFPA No. 54 – latest edition and National Electrical Code
ANSI/NFPA 70-1990 or latest edition and/or local code to
assure safe and efficient operation. In Canada, the installation
must comply with CANICGA-149.1 Natural Gas Installation
Code, or CAN/CGA-B149.2 Propane Gas Installation code, and
local codes where applicable.
In Canada, electrical connection must comply with
applicable sections of the Canadian Electrical Code, C22.1
-1990, (or latest edition), “Safety Standard for Installation,
Part 1” and C22.2 – No. 0-M 1982; (or latest edition), “General
Requirements, Part 2”.
Note: The appliance and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at pressures in excess of
1/2 PSIG (3.45 kPa).
The appliance must be isolated from the gas supply piping
system by closing its individual manual shut-off (not
supplied with appliance) during any testing of the gas supply
piping system at test pressures equal to or less than 1/2 PSIG
(3.45kPa).
INSTALLATION Continued
NOTE: This appliance is not recommended for residential
installation.
Gas Connection
The gas pipe connection is made at the left hand side or right
hand side of the equipment or optionally at rear on some
units. The size of the pipe work supplying the appliance must
not be less than the inlet connection, which is 1 1/4” NPT.
(Note: a 3/4” NPT single unit optional connection must be
specified.) An isolating valve is recommended to be close
to and upstream of the appliance and regulator to allow
shutdown during an emergency or routine servicing. A gas
pressure regulator must be installed at the appliance prior
to connecting the equipment to the gas supply (service)
line. Failure to install a regulator will void the equipment
warranty. After installation, be certain to check the complete
pipe work for leakage.
Electrical Supply
(Models with Convection Oven only)
The electrical supply required is single phase, 115V, 60Hz.
As an option, equipment can be supplied for 240V, 60Hz
operation.
If 240V, the supply must be connected to the terminal block
termination located at the rear of the range for models with
the suffix RC.
For ease in attaching the supply line, there is a removable
cover. A qualified electrician should make the connection to
the mains in accordance with the applicable local codes.
WARNING: Electrical Grounding Instructions.
This appliance is equipped with a three prong (grounding)
plug for your protection against shock hazard and should
be plugged directly into a properly grounded three-prong
receptacle. Do not cut or remove the grounding prong from
this plug.
POWER FAILURE NOTE: In the event of a power failure, no
attempt should be made to operate this oven. This oven is
gas operated but has electrical features, motor and door
switches.
