INSTALLATION INFORMATION
NEVER USE OPEN FLAMES TO CHECK FOR GAS
LEAKS. ONLY USE A COMMERCIAL LEAK DETEC-
TION SOLUTION OR SOAP SUDS AROUND GAS
CONNECTIONS TO CHECK FOR LEAKS. DO NOT
USE LIQUID NEAR VALVE STEMS.
Gas Supply
Installation must conform with local codes or, in the
absence of local codes, with the National Fuel Gas
Code.
Locate the gas supply within the shaded area shown in
the illustration for your specific model on the following
pages. The range is equipped for use with natural or liq-
uid propane (LP) gas. It is design certified by the
Canadian Standards Association (CSA) for natural or
LP gases. The product rating plate has information on
the type of gas that should be used. If this information
does not agree with the type of gas available, check
with the local gas supplier.
The range must be connected to a regulated gas sup-
ply. The supply line must be equipped with an
approved external gas shut-off valve located near the
range in an accessible location. Do not block access to
the shut-off valve. (See Figure 2.1)
A gas supply line of 3/4" (19) rigid pipe must be provid-
ed to the range. If local codes permit, a certified, 3' (.9
m) long, 1/2" (13) or 3/4" (19) ID flexible metal appli-
ance connector is recommended to connect the range
to the gas supply line. For LP gas, piping or tubing size
can be 1/2" (13) minimum. LP gas suppliers usually
determine the size and materials used on the system.
The pipe coming out the back of the range has 1/2"
(13) male threads. Pipe joint compounds, suitable for
use with natural or LP gas should be used.
Wolf LP gas ranges will function up to an altitude of
10,250' (3124 m) without adjustment; natural gas
ranges will function up to an altitude of 8,600' (2621 m)
without adjustment. If the installation exceeds this ele-
vation, contact an authorized Wolf dealer for a high alti-
tude conversion kit.
Leak Testing
Use a brush and liquid detergent to test all gas connec-
tions for leaks. Bubbles around connections will indi-
cate a leak. If a leak appears, shut off the gas valve
and adjust connections. Then check connections
again. Clean all the detergent solution from the range.
This section of the manual covers some of the installation issues that a service technician may need to know when
servicing a gas range. If additional installation information is needed after reviewing this section of the manual,
please refer to the installation guide or contact the Wolf Appliance Customer Service Department.

A domestic gas range requires a 110-120 V AC, 60 Hz
electrical supply with a 15 amp circuit breaker to oper-
ate the electrical ignition system. A ground circuit inter-
rupter (GFCI) is not recommended and may cause
interruption of operation.
The power supply cord provided with the appliance is
equipped with a 3-prong (grounding) plug. The installa-
tion site must be equipped with a properly grounded 3-
prong receptacle. If the electric receptacle or the power
cord are not properly grounded and polarized, this
could cause a shock hazard and the appliance may
experience ignition problems (See Figure 3-2).

Theory of Operation

#822634 - Revision A - January, 2013
THEORY OF OPERATION
A service technician should understand how a gas appliance operates before attempting to service the appliance.
This section provides descriptions of the different types of fuel gases and explains gas heating values. A definition
of specific gravity of gas is given along with its characteristics and effects. Gas combustion principals are explained
and gas burner components are described and illustrated. The end of this section contains illustrations which
demonstrate basic cooking appliance theory of operation.
Types of Fuel Gas:
Gases used to supply heat energy are called fuel gases. Common fuel gases are not simply one kind of hydrocar-
bon, they are mixtures of hydrocarbon gases. They contain other gases as well, such as free hydrogen, carbon
dioxide and nitrogen. As an example natural gas might contain 85% methane, 12% ethane and 3% of other gases.
The presence of each of these gases in the fuel gas has some effect on the nature of the gas.
Some common fuel gasses are methane [CH4], ethane [C2H6], Propane [C3H8] and butane [C4H10]. Propane and
butane are nearly odorless. Natural gas that is processed to remove condensables and moisture, has little or no
odor and no color. Odorants are added to natural gas before distribution to aid in leak detection. A common odorant
used is a colorless liquid containing sulfur compounds.
Heating Value of Gas:
Heat energy produced when burning a fuel gas is commonly expressed in British Thermal Units (BTU). One BTU of
heat will raise the temperature of one pound of water one degree Fahrenheit.
The more carbon and hydrogen atoms in each molecule of a fuel gas, the higher its heating value. Natural gas
which is high in methane has a heating value of about 950 to 1150 BTU per cubic foot. The variance is due to the
various other substances found in natural gases. The more ethane, propane or butane in the gas raises the heating
value. Propane, or LP gas, has a heating value of about 2500 BTU per cubic foot, and butane about 3200 BTU per
cubic foot.
Specific Gravity of Gas:
The specific gravity of a gas is the weight of one cubic foot, or the gas compared to one cubic foot of dry air. When
stating the specific gravity of a gas, a pressure and temperature must be clearly stated. In the gas industry, the
standard conditions of pressure and temperature are 30.0 inches of mercury and 60° F. A pressure of 30.0 inches of
mercury will sustain a column of mercury 30 inches high in a tube with a vacuum on top of the column. Since air is
used as the reference, its specific gravity is always 1.0. This value of 1.0 has no direct physical meaning with
regard to air, such as its density. It is only a relative number or ratio used to express specific gravity of other gases.
The specific gravity of a gas will determine if the gas will rise or fall when released into the air. Natural gas will rise
since its specific gravity is less than 1.0 at 0.4 to 0.8. Propane has a specific gravity of 1.5 and butane 2.0. These
gases will fall when released into the air. They sometimes collect in low spots into pools which become a hazard if
open flames are present.
In addition, specific gravity has two other characteristics. It has an important effect on the flow of gases through ori-
fices, and hence the rating of the burners. Gas flow through an orifice is dependent upon the orifice size and the
gas pressure upstream of the orifice. More of a lighter gas will flow through a given orifice size than a heavier gas
at the same gas pressure. This effect is taken into account in tables and calculators used to select orifice sizes for
burners.
The gas flow in pipes is also affected by specific gravity. At a given pressure at a pipe inlet, more lighter gas will
flow through a pipe than a heavier gas.

Principals of Gas Combustion:
Combustion
When oxygen acts with a substance to produce large amounts of heat rapidly.
Requirements for Combustion
There are three required elements for combustion to occur; Fuel (Gas), Oxygen (Air) and Heat (Ignition
Temperature, which for gas is between 1100°F/593°C and 1200°F/649°C). All must be present. Removing any one
of the three and combustion will cease.
Chemistry of Combustion
Combustion of gas is a chemical reaction between fuel gas and oxygen. The basic elements of common fuel
gasses are hydrogen [H] and carbon [C]. When hydrogen burns, water vapor [H2O] is produced. Complete burning
of carbon in fuel gases form carbon dioxide [CO2] and water vapor [H2O].
Controlled Combustion
Controlled combustion takes place when gas and air are supplied at proper rates to assure complete combustion of
the gas in a steady flame. When a gas appliance is operating properly, burning starts at the burner ports. Gas flow
is controlled by gas orifice size and gas pressure upstream of the orifice. Air is mixed with the gas before it passes
through the burner ports. This added air is called “Primary Air”. The remaining air required for complete combustion
is supplied to the burner at the point of combustion and is called “Secondary air”.
Adjustments of the gas-to-air ratio and the secondary air supply is the key to obtaining stable blue flames at a burn-
er. Proper amounts of primary and secondary air are required for quiet and efficient burner operation and for com-
plete combustion of the gas. Air Shutters or other devices provide control of primary air. Inlet opening and flue out-
lets control Secondary Air flow.
Total air
In an ideal situation, primary and secondary air is all that is needed (for the oxygen required) to burn the gas, but
some additional air is required to assure complete burning of the gas. The total air, “primary”, “secondary” and
“excess” are expressed as percentages of the amount needed. About ten cubic feet of air is required to completely
burn one cubic foot of gas. For this reason an appliance should not be operated in an air tight home.
Limits of Flammability
Not all air-to-gas mixtures will burn. Mixtures with 0% - 4% natural gas in air are too lean to burn. Mixtures of 4% -
14% natural gas in air can burn with a controlled flame. Flammability limits come into play when primary air adjust-
ments are made on burners. If too much primary air is used, the mixture may become too lean and fall below flam-
mability limits, thus preventing combustion.
Incomplete Combustion (Causes and Effects)
To obtain complete combustion, sufficient amounts of air must be supplied to the process. This air must have a rea-
sonably normal oxygen content. Complete burning of gas produces harmless carbon dioxide gas and water vapor.
If the air supply is insufficient, incomplete combustion occurs resulting in the formation of toxic by-products, such as
carbon monoxide [CO] or aldehydes.
Carbon monoxide is colorless and odorless. Inhaling carbon monoxide in sufficient quantities could cause death by
reducing oxygen levels in the blood.
Aldehydes, which are equally dangerous, have a sharp and penetrating odor which is easily detected by smell at
very low concentrations. The odor caused by aldehydes should not be confused with odorants added to natural gas.
The absence of aldehydes does not assure that carbon monoxide is not present. However, if the odor of aldehydes
is present, then carbon monoxide is virtually always present.
Gas Burner Operation
A gas burner is a device to burn gas under control in order to produce useful heat. Primary air is brought into the
burner from outside of the appliance at atmospheric pressure. The gas jet streaming from the orifice draws primary
air with it into the burner.
The gas/air mixture, combined with a spark at the burner port(s) and the secondary air creates a controlled burn.

Surface Burner Components (Refer to Figure 3-1 below):
Burner Cap - Provides the upper portion of the ports required to create a combustible mix and proper flame quality
of the burner and the decorative top for the burner with a black porcelain coating.
Burner - Contains the burner ports where the gas/air mixture ignites. The burner ports are distributed in a useful
pattern to optimize heat transfer. The flames should be spread so they can be easily reached by secondary air and
provide a stable blue flame. The burner also incorporates the Inner Distribution Ring, which Routes the gas from the
simmer orifice to the simmer port holes, and the Outer Distribution Ring, which routes the gas from the main burner
orifice to the main burner port holes.
Venturi - Helps maintain proper and constant primary air injection.
Electrode - The Electrode supplies the spark to ignite the burner. The electrode senses the flame, once the burner
is ignited and will stop sparking. If no flame is sensed, and the valve is opened, the electrode will start sparking to
re-ignite the flame. This is part of the auto-reignition system.
Orifice Holder - This component is mounted to the burner mounting bracket and to the burner box. The Simmer
and Main orifice is threaded into the orifice holder and routes the gas to the appropriate ports of the burner. It is the
main support for the burner components.
Simmer Orifice and Main Orifice - An opening or hole which regulates or limits the amount of gas flowing to a
burner. Gas flow rate (volume) depends on the size of the orifice (hole) and the gas pressure at the inlet of the ori-
fice.

Other Types of Burners:
Blue Flame Burners
All surface burners, including the French Top burners are blue flame burners. With this type of burner, primary air is
mixed with the fuel gas before the gas reaches the burner ports. An orifice is used to regulate gas flow to the burn-
er and is sized to draw exact amount of air into the burner body. Air, which is mixed with the gas inside the burner
body then exits the burner ports located in the burner head, where it is ignited. Secondary air is air from around the
flames. The flame produced has several zones, each represents a stage in burning of the gas. The burner tip has a
thin dark blue cone called the inner or primary cone. A lighter cone called the outer cone, surrounds the inner cone.
Air around the flame diffuses into the flame to burn at the outer cone. If conditions are perfect, products from the
inner cone burn here. The final products of burning are carbon dioxide and water vapor. An outer mantle surrounds
the outer cone where burning is usually completed. It is nearly invisible and glows only because of the high temper-
ature of the final combustion.
Infrared Burners
Wolf Sealed Rangetops also use infrared burners. The under-fired application for the charbroiler and the griddle
uses a porous refractory ceramic tile burner (See Figure 3-2). With this type of burner, a substantial amount of
energy output is in the form of infrared radiant energy. With infrared heat, thermal energy is transmitted through
space without heating the medium through which it travels. Infrared energy is usually not affected by air flowing
between the burners and heated surfaces because of the burner’s numerous and tiny flames. This type of heat is
very efficient and compact. The under-fired refractory infrared burner requires 100 percent primary air and is
designed to have a hot glowing burner surface. The flame burns close to the burner surface at a high temperature.
NOTE: There is no shutter on infrared burners for adjusting the primary air and there is no change in orifice size for
different altitude.

DSI Board Operation (Griddle / French Top / 18” Oven only)
The DSI board serves the purpose of igniting the griddle burner, detecting the presence of this flame, and provides
the signal to open the gas valve. When the thermostat is turned on, the red (call for heat) light comes on and the
gas solenoid is opened. At this time you will hear a series of sparks and it will begin to check for the presence of a
flame. If the igniter probe does not detect flame within a short period of time, the gas valve solenoid shuts off and
there will be a delay before trying to reignite (this allows time for the non-combusted gas to dissipate). This process
will reoccur in three sets and if it fails a third time the DSI board will shut down and will wait for the thermostat to be
turned off and on before attempting to reignite. If flame detection is lost during operation this board will also allow
time for the non-combusted gas to dissipate, and will attempt to reignite after this delay.
After removing burner parts for any reason, it is extremely impor-
tant that the burners are re-assembled correctly. The burner cap
has a special orientation and should be seated flatly (See Figure
3-3).
This patented dual stacked burner configuration makes it possible to enjoy cooking at full flame as well as maintain-
ing control while simmering at the lowest flame setting.

Grate Placement
Low profile cast iron grates are designed for a close fit. This enables pans to move easily from one burner to anoth-
er without having to lift the pan or have it tip over between the grates. Each grate sets securely on dimples on each
corner of the cooktop pan. Continuous grates are interchangeable.
Control Knobs
The control knobs are positioned to correspond to the burners they regulate. The knobs on the far left regulate the
burners on the left side. Conversely, the knobs on the far right regulate the burners on the right side.
Burner Lighting
To light a burner push in and turn the corresponding control knob counter clockwise to the HIGH setting. You will
hear “clicking” and see the burner ignite. Once the burner is lit, continue turning the knob counter clockwise to any
setting, HIGH through LOW.
To select a simmer setting, turn the knob to the LOW setting. You will feel a stop-detente in the knob rotation. Push
in on the knob, continuing to turn it counter clockwise. This moves the flame to the second tier. Now, select any
variation within the SIMMER flame settings, HIGH through LOW.
Each knob is designed to be a “push-to-turn knob”. Although this is a child-safe design, children should never be left
unattended in the kitchen when the range is in use.
Power Outage (Domestic Units Only)
In case of a power outage, the surface burners can be re-lit manually. Turn the control knob to “high” and place a
flame near the igniter to light the burner.

OPERATION OF GAS RANGE SURFACE BURNERS
Surface Burners
A spark electrode ignites each surface burner. This control elimi-
nates the need for continuous open flame pilots. For added safe-
ty and convenience, each burner is designed with an electronic
re-ignition system. This feature enables any burner to automati-
cally re-light in the event it is accidentally extinguished.
This unique dual stacked burner design combines all the burner
parts in one configuration. Large burners provide a Btu/hr rating
of 15,000 on HIGH and a High Simmer Btu/hr rating of approxi-
mately 3300. Small burners provide a Btu/hr rating of 9,200 on
HIGH and a High Simmer Btu/hr rating of approximately 1600. All
burners have simmer settings.
A distinguishing feature of the Wolf low Btu/hr control is its con-
stant, low heat output without continuous ignitions. Flame
diameter remains full size, only the heat output is lowered. This is
the ultimate control for simmering food.

Charbroiler
This optional feature is designed with an infrared burner to give the highest quality and most efficient method of gas
grilling. These burners become an orange-red color at the surface of the ceramic tiles. When the tiles are glowing,
they transfer an intense heat to the food being grilled. This chars the outside of the food and leaves the inside ten-
der and juicy.
The infrared burner is designed to operate at a full heat output of 16,000 BTU/hr. It is recommended using the Wolf
blank-off plate when grilling most foods.
Charbroiler Operation
• Turn on the ventilation hood prior to using the charbroiler.
• If the knob is not set fully at "HIGH", the burner may turn blue and the automatic igniter will begin sparking. Turn
the knob back to "HIGH".
• Preheat grill for about ten minutes before adding the food. The tiles will have an orange glow.
• For the 22-inch charbroiler, there are two separate burners with separate control knobs, which act independently
of each other.

Griddle
The cast iron griddle plate operates at 18,000 Btu/hr. It is thermostatically, controlled which means once the set
temperature is reached, the heat cycles to hold that setting. Prior to use it is necessary to "season" the griddle to
protect the surface from moisture. This process will change the appearance.
NOTE: Seasoning does not create a non-stick surface. The use of additional oil is necessary during cooking.
Griddle Operation
• To heat the griddle, push in the knob and turn counter clockwise to desired temperature. It is normal to hear a
clicking sound. This is the electronic ignition lighting the burner. When the burner is lighted, the thermostat will
control the temperature.
• Preheat for approximately 10 to 15 minutes. When the griddle is preheated, the griddle indicator light will go out.
The light will cycle on and off as the thermostat needs more heat to maintain the set temperature. This will allow
heat to be evenly distributed and reach the set temperature.
• For the 22-inch griddle, there are two separate burners with separate control knobs, which act independently of
each other.
• To turn off the griddle, turn the knob clockwise to the "OFF" position.
Griddle Care
• Use a metal spatula and scrape grease into the grease collection tray.
• When the surface has cooled, wipe it with a paper towel to remove excess grease or oil.
• Clean grease collection tray after each use. Do not allow grease to accumulate in the tray and become a fire
hazard.
• To remove the drip tray, gently pull the tray towards yourself to lift it out. Clean drip tray with soapy water and a
clean cloth.

Oven Burner Components
Blue Flame Oven Bake Burner Components:
Gas Orifice - An opening or hole which regulates or limits the amount of gas flowing to a burner. Gas flow rate (vol-
ume) depends on the size of the orifice (hole) and the gas pressure at the inlet of the orifice.
Air Shutter - This is used to adjust the size of the primary air inlet area and therefore controls primary air flow.
Venturi Tube - A section of pipe at the inlet of the burner body that narrows and then flares out again. This tube
helps maintain a proper and constant primary air injection.
Mixing Tube/Throat - Serves to carry the gas/air mixture from the venturi tube to the burner tube.
Burner Tube - The U-shaped tube containing the burner ports where the gas/air mixture ignites. The burner ports
are distributed in a useful pattern to optimize heat transfer. The flames should be spread so they can be easily
reached by secondary air and provide a stable blue flame.
Electrode - The Electrode supplies the spark to ignite the burner. The electrode senses the flame, once the burner
is ignited and will stop sparking. If no flame is sensed, and the valve is opened, the electrode will start sparking to
re-ignite the flame. This is part of the auto-reignition system.

Venturi Tube - A section of pipe at the inlet of the burner box that narrows and then flares out again. This tube helps
maintain a proper and constant primary air injection.
Mixing Tube/Throat - Serves to carry the gas/air mixture from the venturi tube to the infrared burner box.
Burner Box - The box in the ceiling of the oven with wire mesh on its lower surface that catches the gas/air mixture
allowing from the mixing tube it to gather.
Electrode - The Electrode supplies the spark to ignite the burner. The electrode senses the flame, once the burner
is ignited and will stop sparking. If no flame is sensed, and the valve is opened, the electrode will start sparking to
re-ignite the flame. This is part of the auto-reignition system.
DSI Board Operation (30”, 36” Ovens only)
The DSI detects flame as any other spark module we offer with re-ignition. The flame from the burner produces a
small electrical current that the spark electrode can sense by being in the flame. If a current is detected, the elec-
tronics can adjust spark occurrence or trigger things to happen such as a gas valve. Once the DSI is energized, or
the oven has a call for heat. The following sequence takes place:
• DSI will send 10V to the gas valve to open and allow gas to flow to the burner.
• Sparking starts and continues for 7 seconds or until a flame is detected as mentioned above.
• If no flame is detected, the DSI triggers the gas valve to close, stops sparking, and waits 40 seconds to purge
the gas from the oven.
• DSI will open the gas valve again.
• Sparking will continue for 7 seconds or until flame is detected.
• If no flame is detected again, the system will shut the gas valve, stop sparking and wait 40 seconds for gas
purge.
• If no ignition after this second cycle, the LED oven light will blink showing an issue.
NOTE: If the oven is physically turned off during that 40 second gas purge, the oven will reset that 40 second count
before allowing spark and gas flow. If after 40 seconds, the cycle can be repeated if the oven is turned off, then
back on.
