PRE-INSTALLATION

1. After uncrating the Autobroil™ (broiler), inspect for shipping damage. Check that all control knobs are intact on the electrical cabinet front. Set the broiler in place and leave the plastic wrapping on to protect it from the debris and trash of building construction. DO NOT remove plug from gas inlet pipe. Check that broiler has not been dented or damaged by the carrier. To file a concealed damage claim, follow the instructions attached to the outside of the shipping crate. Warranty does not cover freight damage.

2. Installation must be performed by a Qualified Service Company Company" means any individual, firm, corporation or company which is either engaged in and is responsible for the installation or replacement of gas piping on the outlet side of the meter, or the service regulator when a meter is not provided, or the connection, installation or repair of gas appliances, who is experienced in such work, familiar with all precautions required, and has complied with all the requirements of the authority having jurisdiction.

3. A remote gas shut-off valve must be provided and interlocked to the exhaust fire protection system.

4. This broiler is power fan exhausted, therefore it is necessary to provide adequate make up air equal to the amount removed. In addition, any other exhausts, flues, or air removal systems must be taken into consideration. Examples of this are heat removal fans or hot water heater flues.

5. The broiler must be isolated from the gas supply piping system during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psig (3.45kPa).

BROILER LOCATION

WARNING: IF NOT INSTALLED, OPERATED AND MAINTAINED IN ACCORDANCE WITH THE MANUFACTURER'S INSTRUCTIONS, THIS PRODUCT COULD EXPOSE YOU TO SUBSTANCES IN FUEL OR FROM FUEL COMBUSTION WHICH CAN CAUSE DEATH OR SERIOUS ILLNESS AND WHICH ARE KNOWN TO THE STATE OF CALIFORNIA TO CAUSE CANCER, BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM.

1. Position broiler to properly align with exhaust hood (refer to equipment plan). Note nameplate clearance. The AutoBroil™ is shipped in either a Left to Right or Right to Left configuration based upon customer designation and if needed can be converted to be opposite configuration. See Figure 8 for details. Attention should be paid to the location of a/c registers and hood makeup air. If air from either blows into broiler area, cooking and broiler performance will be affected.

2. The exhaust hood/ventilator for the broiler should be located in accordance with the National Fire Protection Association Standard #96, "Removal of Smoke and Grease-Laden Vapors from Commercial Cooking Equipment" and any local applicable requirements.

3. For proper installation, the minimum clearance from combustible construction is 0" from sides and 18" from food loading end and food delivery end.

4. Make sure broiler is level. The grease drainage and collection system may not function if broiler is not level.

5. Adequate clearance should be maintained to allow easy access to loading and unloading areas of the broiler.

6. For servicing, broiler must be moved two feet clear from all surrounding equipment.

CAUTION: KEEP THE BROILER AREA FREE AND CLEAR FROM COMBUSTIBLES. ELECTRICAL INFORMATION

1. The broiler is furnished with a cord and plug. The broiler requires a 120 Volt A.C., 60 Hz, Single Phase, 3 wire (including ground), 20 AMP circuit. Broiler must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical code ANSI/NFPA No. 70-latest edition.

2. There is a Wiring Diagram located in the Owner's Manual and inside the control cabinet.

WARNING: THIS BROILER IS NOT CAPABLE OF BEING SAFELY PLACED INTO OPERATION DURING A POWER FAILURE AND NO ATTEMPT TO OPERATE IT SHOULD BE MADE.

GAS PIPING TO BROILER

1. Installation of this broiler must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z-223.1-latest edition.

2. In Canada, this broiler is to be installed in accordance with Standard CGA B149.1 or B149.2 Installation Codes for gas burning appliances and equipment and any local applicable requirements.

3. The broiler is supplied with a 3/4" female pipe thread. The installer must make the pipe connection to the broiler in accordance with the "National Fuel Gas Code," ANSI Z-223.1-latest edition. The gas line connected to the 3/4" female pipe thread cannot be less than a 3/4" pipe. The gas pressure and gas volume required by this broiler is shown on Page 5. Gas piping from source to broiler must be adequate to satisfy these requirements when all other gas appliances in the restaurant are operating at maximum demand.

4. A flexible AGA approved gas line is available (#500174 36” flex gas line with restraint). Instructions are:

(1) The installation shall be made with a connector that complies with the Standard for

Optional restraining device is available.

(3) The restraining device must always be connected when the broiler is in operation.

Disconnect for movement necessary for service and cleaning. Then reconnect the restraint when the broiler has been returned to its normal position.

(4) The restraining device is a separate line and should be no less than 6 inches away from the

gas connector. It should also be in a parallel position to the floor. Using the adjustable clamps, alter the length of the cable so that the overall length is 3 to 6 inches shorter than the length of the gas connector including the fittings. Attach the wall bracket to an existing wall or other architecturally sound surface. Attach scissor hook to the wall bracket and secure with cotter pin. Finally, attach the spring hook to the gas broiler. Make certain that the overall length of the line is 3 to 6 inches shorter then the gas connector at this point.

5. See Page 2,Pre-Installation Item 5 for instructions on gas supply line pressure testing.

CAUTION: DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR.

PRE-OPERATION CHECK

Before lighting and operating your broiler, perform a check of critical items as follows:

1. Remove both side panels and check to see that all parts are in place and that none are damaged. Particularly make sure all burners are in place and that the shields are in position on the

bottom burners.

IMPROPER INSTALLATION OF BURNERS CAN CAUSE FLAME / HEAT DAMAGE TO COMPONENTS OR WIRING, FOR EXAMPLE THE PILOT WIRES.

2. Start conveyor chains and check for binding. The conveyor chains should run free and not be catching on any parts.

Wall Bracket

Scissor Hook

OWNER’S MANUAL

MODEL 713BG(DB9L,DB9R)/2424G (DB9A) AUTOBROIL™

3. The speed of the conveyor chains should be changed from slow to fast, and back again without the chain stopping.

4. Before first use, and after any special cleaning, it is necessary to "season" the broiler chain. This is done by bringing the broiler to operating temperature and then (with burners still lit) applying liquid or solid shortening from a saturated cloth over the full width of the broiler chain while the chain makes 5 or 6 complete revolutions.

5. Check that gas pressure at broiler gauges is correct (see Performance Criteria shown in chart below).

6. Check that broiler grease tray is in place under burners (see Figure 3).

PERFORMANCE CRITERIA

1. The manifold pressure for each burner and broiler inlet pressure and gas amount is listed below:

Lower burner manifold pressure is measured by a pressure gauge attached to the lower manifold. With the broiler temperature set to 1000°F the high fire pressure is 5.0 IWC for Natural Gas or 9.0 IWC for LP Gas. High pressure is adjusted using the regulator in the top of the lower burners’ safety gas valve. Low fire is adjusted using the modulating gas valve. See Figure 9 (DB9L) or Figure 13 (DB9R) for gas system layout. Reset the temperature to 830°F (443°C). Once the broiler reaches 830°F, the gas pressure is varied by the modulating valve to maintain 830°F. (NOTE: Broilers with catalysts the temperature is set at 960°F.)

To check low pressure, set the temperature to 400°F and the modulating gas valve will drop the lower burner gas pressure to 1.0 IWC for Natural Gas or 5.4 IWC for LP Gas in an effort to get down to 400°F. Adjust this pressure using the screw located under the plastic cap on the side of the modulating valve. Figure 9 or 13 . With high and low pressures checked and set, reset the temperature to 830°F (443°C) which is the correct cooking temperature.

2. The upper burners in the broiler operate at a fixed pressure and are a special infrared type. All of the air for combustion must be injected through the venturis. This makes orifice design and alignment very critical. The orifice design, in combination with the correct natural or propane gas pressure will result in adequate air aspiration and mixing. There are no air shutters. No air adjustment is needed.

CAUTION: DO NOT STACK BOXES OR IN ANY WAY BLOCK AREA IN IMMEDIATE VICINITY OF VENTURIS OR IN ANY OTHER WAY OBSTRUCT FLOW OF COMBUSTION AIR.

3. The flame rod igniter flame is adjustable with a small screwdriver. The cap screw behind the 1/4" gas line exiting the valve should be removed. The small adjusting screw is under the cap screw. Turning the small adjusting screw inward (clockwise) will reduce the flame to the igniter. The igniter flame should be uniform and just large enough to make a flame envelope around the end of the sensor and igniter.

4. The upper burners will be bright orange when burning properly. If a dull red is observed after 30 minutes of warm-up with a blue flame below the burner face, the orifice may be dirty, damaged, or misaligned. "Popping," or burning back at the orifice of the burner, is a result of the burner screen being loose or a faulty gasket under the burner screen. LP broilers may exhibit a light "popping" sound when the broiler is turned off; this is normal. The lower burners are of a conventional blue flame type.

NOTE: IF BURNER SCREEN IS TORN OR HAS A HOLE, OR IF A GASKET IS LEAKING,

THE BURNER MUST BE REPAIRED (See Figure 5).

III. OPERATING INSTRUCTIONS

BROILER ADJUSTMENT - DAILY LIGHTING INSTRUCTIONS FOR ELECTRONIC IGNITION SYSTEM

1. Turn exhaust system on. (Some hoods are so powerful that the broiler must be lit before the exhaust is turned on).

2. Make sure filters are in place in the hood.

3. Turn broiler on by pressing the On/Off button.

4. The upper burners light first followed by the lower burners 3 minutes later.

5. Verify all of the burners have ignited. Ignition is electronic.

6. If pilot flame or burners fail to light, press the On/Off button for 3 seconds and wait five minutes before attempting to relight.

7. Allow the broiler burners and conveyor chain to warm up until the control displays “Ready” (with the chain at approximately the correct speed).

8. Place one meat patty on the broiler chain. Based on the appearance of the broiled patty, reset the cook time for the desired broiling quality. (Note: this single patty should be cooked to the maximum degree of the Minimum/Maximum doneness tolerance.)

MANUAL LIGHTING INSTRUCTIONS

1. Remove manifold side cover.

2. Press the On/Off button and hold a flame up to the upper burner igniter.

OWNER’S MANUAL

MODEL 713BG(DB9L,DB9R)/2424G (DB9A) AUTOBROIL™

3. Once upper pilot has lit, wait 3 minutes and hold a flame to the lower burner igniter.

This procedure is in case the ignition surface part of the igniter (See Figures 9 & 13) were to break.

If the flame sensor part of the igniter (see Figures 9 & 13) were to break, the igniter must be replaced immediately.

SHUT-OFF INSTRUCTIONS

1. Press the On/Off button for 3 seconds.

2. The control will display Hot and the conveyors will stop running in approximately 10 minutes.

WARNING: If the cool down waiting period is not observed, the conveyor chain may warp.

3. Turn exhaust system off.

NOTE: Note the gas control knob/slide switch on top of each safety gas valve is "ON". All safety gas

valves with a slide switch will have a clear sealant over the switch and connectors. The sealant is to help keep water out of the valve. The switch will always be sealed in the “on” position.

OPERATION OF 6-BUTTON CONTROL

1. USER INTERFACE

The following is the user interface layout.

The Control Panel illustration above shows a typical control interface layout. See Figure 8 for a description of the buttons. You can also refer to the Control Panel Quick Guide at the end of this manual.

TIME AND DATE SETUP

OWNER’S MANUAL

MODEL 713BG(DB9L,DB9R)/2424G (DB9A) AUTOBROIL™

When the controller is in Off mode, the system Time and Date can be adjusted by pressing the Off Button for 10 seconds. The time is displayed on the 1 Down Buttons, the hours are changed. Pressing the View Button moves the “focus” to the MM. Use the Up/Down Buttons to adjust. By pressing View Button again, HH:MM are replaced by DD/MM (or MM/DD, depending on setting of temperature units) (1 travel from one setting to another, and use the Up/Down Buttons to modify. The View Button will return to HH:MM. Pressing the Off Button again stores the new Time and Date, and returns to Off mode.

ON/OFF BUTTONS

A normal press of this button turns on the controller. This causes the broiler to start running the motors at the slowest recipe speed found (overcooked food is safer than undercooked food). This button also starts the gas ignition system and the burners should light. This recipe is selected (its corresponding LED lights up) and the temperature set point is the one defined by this same recipe. At any time in On mode, the user can change the selected recipe. When just turned On, the broiler

will scroll PREHEAT on the 1

line until the Soak Time has elapsed. After this time, broiler will display

either READY, LOW or HIGH, depending on the current temperature readings. A 3-second long press of the On/Off button turns off the broiler. The 1st line will then blink HOT for

the Cool Down period (burners off, but the motors are still running, one at the fastest speed supported by the broiler, one at the slowest speed supported by the broiler). At that point, the broiler

will then simply display OFF, and all outputs will be disabled.

RECIPE BUTTONS

Recipes, there are 6 of them, are defined by a time and a temperature. The time basically sets the conveyor speed. All 6 recipes control the conveyor speed. The top three (3) recipe buttons are for the left conveyor belt and the bottom three (3) buttons are for the right conveyor belt.

When the broiler is READY, a simple press of the recipe button will activate the selected recipe speed and temperature (LOW and HIGH conditions may or may not be triggered).

When a specific recipe must be changed, keep its button pressed for 3 seconds, until the 1 parameter name scrolls on the 1 will also blink, indicating that they can be used. Pressing either Up or Down the 1

makes the display switch to the parameter’s value (preceded by an arrow, as in ►4.25, to indicate a

changeable value). Subsequent presses will then modify the parameter. If Up or Down are not pressed for 5 seconds, the display resumes scrolling the parameter name.

Each recipe has 2 programmable parameters. To switch from one to the next, press the recipe button. After the last parameter is programmed, the broiler resumes normal operation.

VIEW BUTTON

The View button allows a user to view actual or programmed system parameters. Changes cannot be

made just by using this button.

A simple press of the View button allows the user to see the current broiler temperatures and

conveyor speeds (when not in OFF.) Press the View button to scroll through the available viewable parameters ( COOKTIME, GAS TEMPERATURE ) When the wanted parameter is displayed, the Up

button is used to toggle between the parameter name and current value. The Down arrow switches between the current top and bottom recipe speeds (corresponding recipe LED lights up) Pressing the View button one more time when the last parameter is displayed resumes normal operation. If the broiler is in OFF mode, then cook times are not displayed. When they are displayed, they are shown on the 2

Simply pressing the View button shows the current broiler parameters. However, if the View button is

pressed for 3 or more seconds, then the user may view (again, not change) the current recipe programs. After the View button is pressed for 3 seconds, all recipe LEDs start flashing.

The user then selects the recipe they want to view. COOK TIME is the 1

followed by GAS TEMPERATURE.

Use the selected Recipe button to travel through the parameters. Again, the Up button is used to see the parameter value. Keep in mind that these are actual recipe programs, and not current broiler parameters. The blinking recipe LED indicates this. Also, there are no conveyor speeds displayed on the 2 the broiler resumes normal operation.

CONVEYOR ONLY BUTTON

The Conveyor Only mode allows the broiler user to run the conveyors without heating. This may be

for servicing purposes (such as finding the open link on the conveyor). This mode is accessible only

from the OFF mode. Upon power on of broiler (initialization), the display flashes the software revision

number for example 1.15,1.16 or 1.17. This revision must be known to determine the correct operation of the Conveyor Only button.

As soon as the conveyor only button is pressed again the conveyor stops and the broiler resumes

OFF mode.

RECORD/RECOVERY BUTTON

This button is available anytime. When pressed, the controller will list a log of the last 3 recovery

times.

A recovery time is the time required for the temperature to go from 200°F to 50°F below factory set gas temp. This is useful for service and HACCP purposes.

When the Recovery Button is pressed, the controller will successively display GAS1, GAS2 and

GAS3 ramp times, “1” being the most recent ramp logged. To actually see logged time, press the

Up button.

FOOD PROBE BUTTON

This button is useable only when the broiler is On . It is accessible in 2 modes: automatic or manual. In manual mode, it is up to the user to press the Food Probe button to initiate a log, whereas, the automatic mode will remind the user (up to 6 times a day) to take a sample. Even in automatic mode, the user still has the capability to log extra samples manually as he/she wishes.

To do a manual log, the user must first make sure the temperature probe is correctly connected, and then press the Food Probe Button.
