Gas Connection - Viking VGWT240SS Installation Manual

PROXIMITY TO SIDE CABINET INSTALLATION
The unit may be installed directly adjacent to the existing base cabinets. IMPORTANT - The side trim MUST be
(.95 cm) above the adjacent base cabinet countertop. The unit CANNOT be installed directly adjacent to sidewalls, tall
appliances, or other side vertical surfaces above 36" (91.4 cm) high. There must be a minimum of 6" (15.2 cm) side
clearance for the VGWT/VGGT models and 9" (22.9 cm) side clearance for the VGQT models to such combustible
surfaces above 36" (91.4 cm) counter height. Within the side clearance to combustible vertical surfaces above 36"
(91.4 cm), the maximum wall cabinet depth must be 13" (33.0 cm) and wall cabinets within this side clearance must be
18" (45.7 cm) above the 36" (91.4 cm) high countertop. The wall cabinet above the appliance must be a minimum of
42" (106.7 cm) above the appliance cooking surface for a full width of the unit.

GAS CONNECTION

This gas supply (service) line must be the same size or greater than the inlet line of the appliance. This unit uses a 1/2"
3
/ "
8
(1.27 cm) I.D. NPT (Sch40) inlet. Sealant on all pipe joints must be resistive to LP gas.
1. Manual Shut-Off Valve:
This installer-supplied valve must be installed in the gas service line ahead of the appliance and regulator 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 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 appliance, because a regulator is built into each unit at the factory. Under no condition
should you 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 unit. (Gas
conversions are the responsibility of the dealer or end user.)
(c) This unit can be used with Natural gas or LP/Propane. It is shipped from the factory adjusted for use with
natural gas. The orifice hoods must be screwed snug when LP/Propane 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 gas requires
10" 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 unit 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 (3.5kPa).
(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
(3.5kPa).
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" I.D. NPT (with suitable strain
reliefs) in compliance with ANSI Z21.41 and Z21.69.
(b) 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.
(c) In Massachusetts: This appliance must be installed with a 36" (3-foot) long flexible gas connector.
4. Before placing the unit into operation, always check for gas leaks with a soapy water solution or other acceptable
method. DO NOT USE AN OPEN FLAME TO CHECK FOR LEAKS!!! Leak testing of the appliance shall be
conducted according to the manufacturer's instructions.
NATURAL TO LP/PROPANE CONVERSION INSTRUCTIONS
This product is manufactured and adjusted for operation with natural gas as shipped from the factory. To operate with
LP/Propane gas, the following adjustments should be made:
1. Before installing, convert the regulator by removing the cap marked "NAT" and reverse it to read "LP". Be sure not
to disturb or remove the spring beneath the cap.
2. To convert the burner to LP/Propane, turn the burner orifice hood clockwise until it becomes snug against the
internal LP/Propane pin orifice.
3. See the "Burner Adjustment" section to obtain a properly adjusted flame for the burners.
