Manual Shut-Off Valve; Pressure Regulator; Flexible Connections; Rigid Connections - Viking VGSO100 Service Manual

Manual Shut-Off Valve:

This 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 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 oven
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. 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 these ovens can withstand
a maximum input pressure of 1/2" PSI (14.0"
W.C.P.). If the line pressure is in excess of
1/2" PSI (14.0" W.C.P.), 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 Z21.41and Z21.69.

General Information

Rigid Connections:

Incoming gas from the service supply is
brought from an intake pipe (not supplied) to
the back center of the unit through the shut-
off valve (not supplied) to the regulator. (See
"Cutout Dimensions" section for gas inlet
location.)
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
DO NOT use the handl e or oven door to lift
the oven. Remove door before installation to
ensure that it is not used to lift the unit.
! WARNING
NEVER use this applian ce as a space heater
to heat or warm the room. Doing so may
result in carbon monoxide poisoning and
overheating of the oven.
! CAUTION
Before placing the oven 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.
! CAUTION
DO NOT use the handle or oven door to lift
the oven. DO NOT lift or carry the door by the
handle. Removing the door must be done by
your dealer, a qualified licensed plumber, or
certified gas installer.
