Cooktop Controls

Electronic Ignition and Automatic Reignition

The range is equipped with electronic ignition which eliminates the need for a standing pilot light.

The burners on this range will automatically relight if the ﬂ ame goes out.

All surface burner igniters will spark and make clicking sounds when any burner is turned on or if automatic reignition occurs. Do not touch any of the burners when igniters are clicking.

Occasionally the burners may spark if excess wind or a draft blows the ﬂ ame away from the burner’s ﬂ ame sensor.

The griddle and IR (infrared) grill are equipped with Glo-Bar igniters. The Glo-Bar remains energized whenever the griddle or IR grill is in use to ensure the burner always stays lit.

In case of a power outage, you can light the

surface burners on your cooktop with a match. Hold a lighted match to the burner, then turn the knob

to the LOW position. Use extreme caution when

lighting burners this way.

After the burner ignites, turn the knob to adjust the

ﬂ ame size.

To turn a burner off, turn the knob clockwise, as far as it will go, to the OFF position.

Do not operate a burner for an extended period • of time without cookware on the grate. The ﬁ nish on the grate may chip without cookware to absorb the heat.

The indicator light on each bezel veriﬁ es • the burner is on. However, it should not be a substitute for visually checking the ﬂ ame at the burner.

Dual-ﬂ ame Stacked Burners

All surface burners on your range have two sets of

ﬂ ames stacked one on top of the other; the dual- ﬂ ame burners have a lower (simmer) ﬂ ame and a

upper (main) ﬂ ame.

When a burner is turned on, the lower ﬂ ame will always light and stay on.

Lower Flame

Do not attempt to light the grill or griddle during a power outage. The gas to these burners will automatically shut off during a power outage.

To Light a Surface Burner

Push the control knob in and turn it

counterclockwise to the LITE position.

ON Indicator

Light

Upper Flame

Lower Flame

Simmering:

The stacked burner design provides a wide range of heat settings with which to simmer. Depending on the type and quantity of food, and pan size, the ﬂ ame can be adjusted to suit your speciﬁ c need. The lowest setting uses only the lower ﬂ ame and can maintain delicate foods at a safe 140°F.

Cooking:

Settings from LO to X-HI will use both upper and lower ﬂ ames. Use LO to HI for all purpose cooking. Use HI or X-HI (highest setting) with larger diameter

cookware.

X-HI and HI are very high heat settings and are

intended to sear foods quickly and boil large quantities of water.

Using the IR Grill

Remove the cover before lighting the burner. The

cover must be removed when using the IR grill.

Set the control knob to PREHEAT. The longer the grill

is preheated, the darker the grill marks will be on the food.

It may take up to 15 minutes to fully preheat the grill.

After preheat, the control knob may be set to any

position between HI and LO.

Do not leave the grill unattended at any time. Note: The grill will take approximately 45 seconds to

ignite. Unlike the surface burners, which use electric igniters, the grill uses a Glo-Bar for ignition. It takes approximately 45 seconds for the Glo-Bar to reach temperature. Gas is only supplied to the grill once the Glo-Bar reaches temperature.

Using the Griddle

To heat the griddle, push in the control knob and turn to the desired Temperature setting. The light on the bezel will glow to indicate the thermostat control is working.

The griddle can be leveled. Remove the ﬂ ue cover by lifting it straight up. The two inner screws are clamping screws for securing the griddle in place.

Loosen these two screws before leveling. Do not

remove these two screws. The two outer screws are leveling screws. Do not

remove these two screws. They can be turned to

level the griddle or to provide a forward slope to help grease and oils to drain away from the food being cooked. After the ﬁ rst few uses, you will be able to judge the slope best suited for the foods you are cooking and personal preference.

After leveling the griddle, tighten the clamping

screws to secure griddle in place. Hand tighten

screws; do not over-tighten.

The griddle is thermostatically controlled and can be set to maintain any temperature from 200ºF to 450ºF.

Note: Unlike the surface burners, which use electric

igniters, the griddle uses a Glo-Bar for ignition. It takes approximately 45 seconds for the Glo-Bar to reach temperature. Gas is only supplied to the griddle once the Glo-Bar reaches emperature.

Introduction to Convection Cooking

The Monogram reverse-air convection system consists of two dedicated heating elements wrapped around the convection fan. After preheating to the set temperature, all heat in CONV BAKE mode comes from these two dedicated elements. The convection fan periodically pauses, then changes direction to best distribute hot air throughout the oven. As a result, foods are evenly cooked and browned―often in less time with convection heat.

Note: The convection fan shuts off when the oven

door is opened.

How to Set the Oven for Convection Baking or Roasting

Convection Baking is ideal for evenly browned baked foods cooked on single or multiple racks. Select Convection Roast to roast large, tender cuts of meat uncovered.

When set on CONV BAKE or CONV ROAST, the rear convection elements and the fan operate when the oven

is heating.

Turn the Oven Mode Selector to 1. CONV BAKE or CONV ROAST.

Using the Temperature knob, set the desired temperature, in 25°F increments, from 175°F to 550°F.2.

The oven will now begin to preheat. The emperature display will begin at 100°F and remain there until the oven exceeds that temperature. From that point , the display will show the actual temperature.

The interior lights will turn on and stay on until the oven is turned off. The convection oven fan will turn on during preheat. The control will beep when the oven is preheated and food can be placed inside the oven.

3. Turn the Oven Mode Selector and the Temperature knob to OFF when convection cooking is ﬁ nished. Note: A cooling fan will turn on to cool internal parts. This is normal, and the fan may continue to run even

after the oven is turned off.

Use the temperature probe when a precise internal temperature is important. See Owner's Manual.

How to Set the Oven for Prooﬁ ng

How to Set the Oven for Cleaning

The prooﬁ ng feature maintains a warm environment which is useful for rising yeast-leavened dough.

Turn the Oven Mode Selector to 1. PROOF. The

display will show “PrF”. PROOF mode will not operate when oven is above 125°F. The display will scroll “too hot”. Allow the oven time to cool.

For best results, cover the dough with a cloth or with greased plastic wrap.

Caution: See owner's Manual for Self-cleaning

safety precautions.

Turn the Oven Mode Selector to 1. CLEAN. Turn the Temperature knob to 2. CLEAN.

Use rack position B or C in the large oven. Use rack position B in the companion oven. See Owner's Manual.

The prooﬁ ng feature automatically provides the optimum temperature (95°F) for the prooﬁ ng process; therefore the Temperature knob does not affect the proof temperature.

The oven interior lights cycle on and off as necessary to maintain optimum proof temperature until the Oven Mode Selector has been turned to

OFF.

To avoid lowering the oven temperature and • lengthening prooﬁ ng time, do not open the oven door unnecessarily.

Check bread products early to avoid over-• prooﬁ ng.

2. When prooﬁ ng is ﬁ nished, turn the Oven Mode

Selector to OFF.

The symbol will ﬂ ash as the oven door is locked. It will not be possible to open the oven door during the clean cycle.

4. After the clean cycle is complete and the oven has cooled, “End” will show in the display and the will turn off. Turn the Oven Mode Selector

and the Temperature knob to OFF.

To interrupt a clean cycle, turn the Oven Mode

Selector and the Temperature knob to OFF. When

the oven has cooled to a safe temperature, the symbol will turn off indicating the door may be opened.

An interrupted clean cycle cannot be restarted until after the oven is cool enough for the door to unlock.

Installation

Installation information is for reference only. See the Installation Instructions shipped with the product for complete details and before attempting to install the range or rangetop.

Caution: These ranges weigh up to 700 pounds.

Some disassembly will reduce the weight considerably. Rangetops weigh up to 170 pounds. Due to the weight and size of the range or rangetop, and to reduce the risk of personal injury or damage to the product:

TWO PEOPLE ARE REQUIRED FOR PROPER • INSTALLATION OF 36" AND 30" RANGES AND 36" AND 48" RANGETOPS.

THREE PEOPLE ARE REQUIRED FOR PROPER • INSTALLATION OF 48" RANGES.

Gas Supply Range and Rangetop

The natural gas models are designed to operate at 5" water column pressure. For proper operation, the pressure of the natural gas supplied to the regulator must be between 7" and 13" water column.

ADJUST BURNER FLAMES

Normally, burners do not need further adjustment. Make adjustments only when necessary.

A. Turn on the gas. Plug in electrical cord. B. Turn all burners on highest setting and check

the flames. They should be blue in color. When using LP gas, the flames may have some yellow tipping at the ends of the flame. Foreign particles in the gas line may cause an orange flame at first, but this will soon disappear.

C. Turn the burner knob to “LO” while observing the

flame.

Adjust the setting of the upper row of flames using the valve bypass screw as follows:

Adjustments must be made with two other burners in operation on a medium setting. This prevents the upper row of flames from being set too low, resulting in the flame being extinguished when other burners are turned on.

D. To adjust the flame, remove the knobs. Insert a small

flat-blade screwdriver into the hole in the center of the valve stem to engage screw.

• If the flames are too small or flutter, turn the screw counterclockwise.

Oven Operational Notes

Certain modes, when selected, will automatically enter into a preheat. The temperature knob is used to set the desired temperature, in 25°F increments, from 175°F to 550°F. The oven will now begin to preheat. The temperature display will begin at 100ºF and remain there until the oven exceeds that temperature. From that point, the display will show the actual temperature.

Note: A cooling fan will turn on to cool internal

parts. This is normal, and the fan may continue to run even after the oven is turned off.

• If the flames are too large, turn the screw clockwise.

E. Make the adjustment by slowly turning the screw

until flame appearance is correct.

Note: Once the conversion is complete and checked,

ﬁ ll out the conversion label and afﬁ x the label near the rating label. For ranges, place the label beneath the control panel. For rangetops, place the label on the bottom of the unit.

Preheat operation consists of multiple phases, • which are time and/or temperature dependant. Each phase of preheat utilizes combinations of inner and outer bake, broil, and inner convection elements. For example, one phase may use inner convection and outer broil simultaneously. Another phase may use inner broil and outer bake simultaneously.

At the start of Preheat, the convection fan • will delay running for 10 seconds. It will then run CCW with no directional changes for the remainder of Preheat.

– 25 –

Page 26

The convection fan will cycle on and off while • cooking to best distribute hot air in the oven. The convection fan shuts off when the oven door is opened.

Different broil elements are used in each broil • mode. There are 2 different broil modes, each providing a HI and a LO setting.

The Convection Broil mode uses both the inside • and outside broil elements and convection fan.

Broil will not work if the temperature probe is • plugged in.

When using the probe, you can use the timer, • but you cannot use timed oven operations.

In Convection Bake, both the inner and the outer • convection elements cycle and the fan operates whenever the oven is heating.

Convection Broil will not work if the temperature • probe is plugged in. Never leave your probe inside the oven during a broil cycle.

The Clean cycle can be set for a minimum of 3 • hours and a maximum of 5 hours. The default setting is 5 hours. The 5-hour set time consists of 4 hours and 15 minutes of cleaning and 45 minutes of cool down. The door will unlock at an approximate temperature of 450°F.

On double oven models, the ovens can be set to • self clean in sequence. The ﬁ rst oven set starts the cycle. The second oven will start cleaning as soon as the ﬁ rst oven has cooled to 550°F (it should already be below 550°F at the end of a standard 5-hour clean since a 45 cool-down is included in the time). If the ﬁ rst oven clean cycle is cancelled, the second oven will start cleaning immediately or as soon as the ﬁ rst oven cools below 550°F.

Self-Clean will not work if the temperature probe • is plugged in or if the Sabbath feature is set.

Prooﬁ ng will not operate when oven is above • 125°F. The display will show “too hot”. Allow the oven time to cool.

rectangular glow-bar. The grill and griddle ignition circuits consist of the control, an igniter, a hi limit switch (griddle only), and a safety valve. These components are wired in series for each cooking function.

The most important points to know about the ignition system are:

Switch Plate

6. Remove wires from the LED switch.

7. Remove wires from the control.

• THE IGNITER RESISTANCE DECREASES AS THE IGNITER SURFACE TEMPERATURE INCREASES.

• THE SAFETY VALVE OPERATES BY CURRENT, NOT VOLTAGE.

From a cold start, the igniter needs 30 to 60 seconds, with a minimum of 116 volts applied, to reduce its electrical resistance enough to provide a minimum of 2.9 amps of current ﬂ ow in the series circuit. This is the required current ﬂ ow needed for the safety valve to open and supply gas to the burner.

The glow-bar should provide a steady current ﬂ ow of 3.4 to 3.6 amps (3.03 / 3.3 VAC) in the circuit. At that point, the igniter temperature is 1800°F to 2500°F (982°C to 1371°C). The igniter will remain energized at all times during burner operation. If the igniter glows red but does not draw at least 2.9 amps, the fault is usually with the igniter, not the valve.

Always check the gas shut-off valve located next to

the pressure regulator for a Not On condition.

8. Slide the capillary out of the griddle burner box.

Glow-bar Igniter

Surface Burner Base

WARNING: The range and rangetop use rect-

angular Norton glow-bar igniters. They are NOT INTERCHANGEABLE with cylindrical Carborundum

glow-bar igniters. The two types of glow-bar igniters operate at different amperage and use different gas valves.

Check the glow-bar circuit with a clamp-on ammeter. If igniter glows red but circuit does not draw at least 2.9 amps, the fault is likely with the igniter, not the valve.

Note: If igniter glows, but ignition does not occur, be

sure the gas shut-off valve on the pressure regulator is in the open position.

Slow ignition can be caused by one or more of the following conditions:

Blockage of primary air intake: Inlet slots under 1. bullnose (near LED light locations) must be open.

Blockage of secondary air intake holes: 2. Examine grill and griddle burner boxes (galvanized box surrounding burner) and inspect the secondary holes beneath the burner for signs of blockage.

Note: The following describes the procedure to

remove a single burner base. The procedure to remove the remaining burner bases is identical.

To remove the burner base:

Lift off the burner grates, cap, and burner head.1.

Note: Five T-15 Torx screws attach the surface

burner: 3 coarse thread screws on the outside, and 2 ﬁ ne thread screws on the inside.

2. Remove the three T-15 Torx screws that attach the burner base to the burner pan and the two T-15 Torx screws that attach the burner base to the burner.

Improper alignment of oriﬁ ce hood and burner: 3. Oriﬁ ce must be pointing straight into burner venturi.

Improper air/gas adjustment.4.

Blockage of griddle burner gas exit holes. 5. Internal restriction or partial restriction inside the grill burner assembly.

The ignitor should draw approximately 3.4 to 3.6 6. amps when operating. To check, carefully use a clamp-on ammeter at one of the igniter leads.

Grill Igniter Circuit Test

Caution: When removing the wire from the igniter,

make sure you do not damage the heat shrink insulation on the wire. If damaged, repair the wire insulation with ﬁ berglass tape.

Lift each burner base, note the color of the 3. igniter wire, then disconnect the igniter wire.

Dual Encoder Board

*LINbus: (Local Interconnect Network) : A communication network comprised of a LIN master and one or more LIN slaves. In this double oven range, the logic board acts as the LIN master while the dual encoder boards, (temperature encoders), and relay boards are the LIN slaves. The logic board sends messages to the other components based on a predeﬁ ned list of commands.

All the components receive a signal to perform a speciﬁ c task, but only the appropriate component will act on the message and respond accordingly. The component which acts on the speciﬁ c task is based on programming in the control. Since the LINbus signal is a digital control signal, special equipment, such as an oscilloscope, is required to measure it.
