Electrical Requirements
This product is manufactured with the
neutral terminal connected to the cabinet.
Use a 3-wire, agency approved, power
supply kit with closed loop terminals rated
per the National Electrical Code, ANSI/NFPA
70-latest edition (See Rating chart below). If
local codes prohibit grounding through the
neutral, use a 4-wire, agency approved,
power supply kit with closed loop terminals
rated per the National Electrical Code,
ANSI/NFPA 70-latest edition (See Rating
chart below).

model/serial rating plate.
A GFI
shall be used if required by NFPA-
70 (National Electric Code),
federal/state/local laws, or local
ordinances.
• The required use of a GFI is normally
related to the location of a receptacle with
respect to any significant sources of water
or moisture.
• Viking Range Corporation will NOT
warranty any problems resulting from GFI
outlets which are not installed properly or
do not meet the requirements below.
If the use of a GFI is required
, it should be:
• Of the receptacle type (breaker type or
portable type NOT recommended)
• Used with permanent wiring only
(temporary or portable wiring NOT
recommended)

Incoming line pressure upstream from the
regulator must be 1” W.C.P. higher than
the manifold pressure in order to check
the regulator. The regulator used on this
range can withstand a maximum input
pressure of 1/2” PSI (14.0” W.C.P.). If the
line pressure is in excess of that amount, a
step down regulator will be required.
• The appliance must be disconnected from
the gas supply piping system during any
pressure testing of that system.
Flexible Connections:
If the unit is to be installed with flexible
couplings and/or quick-disconnect fittings,
the installer must use a heavy-duty AGA
design-certified flexible connector of at least
1/2” (1.3 cm) ID NPT (with suitable strain
reliefs) in compliance with ANSI Z21.41
and Z21.69.
In Canada:
CAN 1-6, 10-88 metal
connectors for gas appliances and CAN
1-6.9 M79 quick disconnect devices for use
with gas fuel.
In Massachusetts:
This appliance must be
installed with a 36” (3-foot) long flexible
gas connector.
WARNING
Electrical shock hazard.
To avoid the risk of electrical
shock, personal injury or death;
verify electrical power is turned
off at the breaker box and gas supply is
turned off until the range is installed and
ready to operate, installation by an
authorized installer only.
• On a dedicated circuit (no other
receptacles, switches or loads in the
circuit)
• Connected to a standard breaker of
appropriate size (GFI breaker of the same
size NOT recommended)
• Rated for Class A (5 mA +/- 1 mA trip
current) as per UL 943 standard
• In good condition and free from any
loose-fitting gaskets (if applicable in
outdoor situations)
• Protected from moisture (water, steam,
high humidity) as much as reasonably
possible
Gas Connection
The gas supply (service) line must be the
same size or greater than the inlet line of the
appliance. This range uses a 1/2” (1.3 cm) ID
NPT (Sch40) inlet. Sealant on all pipe joints
must be resistive to LP gas.
The range is designed specifically for
natural gas or liquid propane (LP) gas.
Before beginning installation verify that
the model is compatible with the intended
gas supply.
Manual shut-off valve:
The installer-supplied valve must be installed
in the gas service line before the appliance
in the gas stream and in a location where it
can be reached quickly in the event of
an emergency.
In Massachusetts:
A “T” handle type
manual valve must be installed in the gas
supply line to the appliance.
IMPORTANT: Any conversion required
must be performed by your dealer or a
qualified licensed plumber or gas service
company
.
Please provide the service person with this
manual before work begins.
Pressure Regulator:
• All heavy-duty, commercial type cooking
equipment must have a pressure regulator
on the incoming service line for safe and
efficient operation, since service pressure
may fluctuate with local demand. External
regulators are not required on this range
since a regulator is built into each unit at
the factory. Under no condition bypass this
built-in regulator.
• Manifold pressure should be checked with
a manometer, natural gas requires 5.0”
W.C.P. and LP gas requires 10.0” W.C.P.
