In Massachusetts; Pressure Regulator; Flexible Connections; In Canada - Viking DSCD130 Service Manual

General Information

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. 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
(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 / " (1.3 cm) ID NPT (with suitable strain reliefs) in
1
2
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.

Performance Checklist

A qualified installer should carry out the following checks:
• Check top burner ignition. See drawing for proper
flame height on HI. The low flame should light at every
port.
• Check oven bake function—bake element on full
power, center and outside broil elements at partial
power.
• Convection bake function—bake and broil elements
the same with the convection fan on.
• Check TruConvec™ function—TruConvec element
(behind convection fan cover) on and convection fan
on.
/ " PSI
1 • Check HI broil function–both broil elements at full
2
power.
• Check LOW broil function—inner broil element only.
• Check convection broil function—both broil elements
at full power with convection fan on.
• Check self-clean function—door will lock in
approximately 30 seconds, the center and outside broil
elements will turn on and the bake element will turn on
at partial power. Check broil elements through window
to make sure they are on, then abort self-clean cycle
to unlock door.
When conducting performance test, DO NOT run self-
clean cycle for more than 10 minutes with oven racks
inside oven. This could cause them to discolor due to
the high temperature required for self-cleaning.
