General Information
8 ©2009 Viking Preferred Service
Self-Clean Oven
• Clean only parts listed in this guide. DO NOT clean
door gasket. The door gasket is essential for a good
seal. Care should be taken not to rub, damage, or
move the gasket. DO NOT use oven cleaners of any
kind in or around any part of the self-clean oven.
• Before self-cleaning the oven, remove broiler pan,
racks, and other utensils and wipe up excessive
spillovers to prevent excessive smoke or flaming.
• This range features a cooling fan, which operates
automatically during a clean cycle. If the fan does not
turn on, cancel the clean operation and contact an
authorized servicer.
• It is normal for the rangetop cooking surface of
the range to become hot during a self-clean cycle.
Therefore, touching the rangetop cooking surface
during a clean cycle should be avoided.
Important Safety Notice and Warning
The California Safe Drinking Water and Toxic
Enforcement Act of 1986 (Proposition 65) requires the
Governor of California to publish a list of substances
known to the State of California to cause cancer or
reproductive harm and requires businesses to warn
customers of potential exposures to such substances.
Users of this appliance are hereby warned that when
the oven is engaged in the self-clean cycle, there may
be some low-level exposure to some of the listed
substances, including carbon monoxide. Exposure to
these substances can be minimized by properly venting
the oven to the outdoors by opening the windows and/or
door in the room where the appliance is located during
the self-clean cycle.
Important notice regarding pet birds:
NEVER keep pet birds in the kitchen or in rooms where
the fumes from the kitchen could reach. Birds have
a very sensitive respiratory system. Fumes released
during an oven self-cleaning cycle may be harmful or
fatal to birds. Fumes released due to overheated cooking
oil, fat, margarine and overheated non-stick cookware
may be equally harmful.
About Your Appliance
NEVER use appliance as a space heater to heat
or warm a room to prevent potential hazard to the
user and damage to the appliance. DO NOT use
the rangetop or oven as a storage area for food or
cooking utensils.
• For proper oven performance and operation, DO NOT
block or obstruct the oven vent duct located on the
right side of the air grille.
• Avoid touching oven vent area while oven is on and
for several minutes after oven is turned off. When the
oven is in use, the vent and surrounding area become
hot enough to cause burns. After oven is turned off,
DO NOT touch the oven vent or surrounding areas
until they have had sufficient time to cool.
• Other potentially hot surfaces include rangetop, areas
facing the rangetop, oven vent, surfaces near the vent
opening, oven door, areas around the oven door and
oven window.
• The misuse of oven doors (e.g., stepping, sitting, or
leaning on them) can result in potential hazards and/or
injuries.
ELECTRICAL SHOCK HAZARD. DO NOT touch
a hot oven light bulb with a damp cloth as the bulb
could break. Should the bulb break, disconnect
power to the appliance before removing bulb to avoid
electrical shock.
ELECTRICAL SHOCK HAZARD. Disconnect the
electric power at the main fuse or circuit breaker
before replacing bulb.
BURN OR ELECTRICAL SHOCK HAZARD. Make
sure all controls are OFF and oven is COOL before
cleaning. Failure to do so can result in burns or
electrical shock.
DO NOT turn the temperature control on during
defrosting. Turning the convection fan on will
accelerate the natural defrosting of the food without
the heat.
BURN HAZARD. The oven door, especially the glass,
can get hot. Danger of burning: DO NOT touch the
glass!

General Information
©2009 Viking Preferred Service 9
This range features a self-cleaning cycle. During
this cycle, the oven reaches elevated temperatures
in order to burn off soil and deposits. A powder
ash residue is left in the bottom of the oven after
completion of the self-clean cycle.
NOTE: DO NOT use commercial oven cleaners
inside the oven. Use of these cleaners can produce
hazardous fumes or can damage the porcelain
finishes. DO NOT line the oven with aluminum foil or
other materials. These items can melt or burn during
a self-clean cycle, causing permanent damage to the
oven.
DO NOT touch the exterior portions of the oven after
self-cleaning cycle has begun, since some parts
become extremely hot to the touch!
During the first few times the self-cleaning feature is
used, there may be some odor and smoking from the
“curing” of the binder in the high-density insulation
used in the oven. When the insulation is thoroughly
cured, this odor will disappear. During subsequent
self-cleaning cycles, you may sense an odor
characteristic of high temperatures.
KEEP THE KITCHEN WELL-VENTED DURING THE
SELF-CLEAN CYCLE.
BURN HAZARD. When self-cleaning, surfaces may
get hotter than usual, therefore, children should be
kept away.
DO NOT store items of interest to children over
the unit. Children climbing to reach items could be
seriously injured.
Electrical & Gas Requirements
Electrical Requirements
Check your national and local codes regarding this unit.
This range requires 3 wire or 4 wire, 240-208 VAC/60
Hz. See “Appendix A” for grounding instructions. Unit
must be fused separately from any other circuit.
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.
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
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.
Connecting Gas & Electric
Gas leak hazard. To avoid risk of personal injury
or death; leak testing of the appliance must
be conducted according to the manufacturer’s
instructions. Before placing appliance in operation,
always check for gas leaks with soapy water solution.
DO NOT USE AN OPEN FLAME TO CHECK FOR
GAS LEAKS.
Connect gas and electrical. Before placing appliance
in operation, always check for gas leaks. This must be
performed by your dealer, a qualified licensed plumber,
or gas service company.

General Information
10 ©2009 Viking Preferred Service
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 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.

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.
3/8”
(0.95 cm)
1-1/2”
(3.8 cm)
• 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.
• Check HI broil function–both broil elements at full
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.

Before Using Range
All products are wiped clean with solvents at the factory
to remove any visible signs of dirt, oil, and grease which
may have remained from the manufacturing process.
Before starting to cook, clean the range thoroughly with
hot, soapy water. There may be some burn off and odors
on first use of the appliance–this is normal.
Oven
Important: Before first use, wipe interior with soapy
water and dry thoroughly. Then, set the oven selector to
bake, the thermostat to 450°F, and operate for an hour.
All models include:
• A broad range of baking and broiling modes—up to
eight cooking modes in all—to make even your most
challenging baking projects a success.
• Exclusive VSH™ Pro Sealed Burner System
(VariSimmer™ to High)—combination of patented
burner and top design provide cleanability plus
superior performance at simmer and high.
• Exclusive one-piece tooled and porcelainized cooking
surface contains spills for easy cleaning.
• Split baking and broiling elements—which reduces
preheating time and provides greater control and more
even heating.
• A reversing fan which is two times larger than most
on the market—this allows you to cook foods more
thoroughly and evenly—even when baking large
quantities.
• Four convection modes offering greater air circulation
to shorten cooking times and cook foods more evenly.
• Three broiling modes, including a new low-broil mode
for delicate broiling and top-browning.
• A profiled, concealed bake element for easier cleaning.
• This appliance is certified by Star-K to meet strict
regulations in conjunction with specific instructions
found on www.star-k.org.
