Gas Connection - Viking Professional Custom VGSC5304B Install Manual

GAS CONNECTION

All gas connections must be made according to national and local codes. This gas supply (service) line must be the
same size or greater than the inlet line of the appliance. This range uses an ISO7 or ISO128 inlet. The inlet depends
on the end users national and local codes.
1. Manual Shut-off Valve:
This installer-supplied valve must be installed in the gas service line ahead of the appliance in the gas stream and in
a position 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.
2. Pressure Regulator
a) 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, because a regulator is built into each unit at the factory. Under no
condition bypass this built-in regulator.
b) 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 is started on the range. (Gas
conversions are the responsibility of the dealer or end user.)
c) This range can be used with Natural or LP/Propane gas. It is shipped from the factory adjusted for use with
natural gas. The orifice hoods must be screwed snug when LP/Propane gas is used. (See LP/Propane
conversion.)
d) Manifold pressure should be checked with a manometer, natural gas requires 5.0" W.C.P. and LP/Propane
requires 10.0" W.C.P. 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.
e) The appliance, its individual shut-off valve, and pressure regulator 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).
f) The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off
valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2
psig (3.45 kPa).
3. Flexible Connections:
a) 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 commercial 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 standards.
b) In Canada: CAN 1-6.10-88 metal connectors for gas appliances and CAN 1-6.9 M79 quick disconnect
device for use with gas fuel.
c) In Massachusetts: This appliance must be installed with a 36" (3-foot) long flexible gas connector
CAUTION: Leak testing of the appliance shall be conducted according to the manufacturer's instructions. Before
placing the oven into operation, always check for leaks with a soapy water solution of other acceptable method. DO
NOT USE AN OPEN FLAME TO CHECK FOR LEAKS!
