(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.

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.

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.

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
st
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.

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.

seconds causes the rate of change to accelerate to 25°F/10°C (temperature), or 20 seconds (time) every 500 msec.
3. DISPLAY
GENERAL
In general, all messages are scrolled on the 1st line (about 2 characters per second), and times are displayed on the 2
Some buttons have a LED, which is used to indicate various situations.
On/Off LED: full on when broiler is On, otherwise Off.
Up/Down LED’s: blink when Up/Down buttons are expected.
Recipe LED’s: on when a recipe is active, blinking when programming or viewing recipes.
Conveyor Only: blinking when feature is in use.
Recovery: full on when feature is in use.
View: full on when feature is in use.
Conveyor: this is a group of 3 LED’s that simulate a rotating motion (about 2 changes per
second). This is active whenever the controller is receiving pulses from all installed tachometers.
Top and Bottom Heater LED’s: full on when the corresponding heaters are on, otherwise off.
Also, whenever the arrow symbol (X) is displayed with the data, this means that this is a parameter being changed/adjusted.
TIME DISPLAY
All conveyor speeds are displayed on the 2
displayed as MM.SS, or HH:MM . For example, 9.59 is 9 minutes and 59 seconds, and 1:10 is 1
hour and 10 minutes.
3. SYSTEM STATES
There are several states of operation as follows:
POWER-UP MODE
When a power-up occurs, there is a lamp test, where all LED’s come on for 5 seconds (this includes all LED’s in the two displays). Following the lamp test, the software number and revision are displayed. These are useful for troubleshooting purposes when several versions exist in the field.
The first line shows the software number and the second line shows the revision in the format 1.15. Normally, major release versions will be whole numbers (1.00, 2.00, etc.) and if a fraction occurs,
these are minor release versions. Following this, the broiler falls automatically into Off mode.
OFF STATE
In this state, the heaters are disabled. Nothing is displayed, except for OFF on the 1

ON STATE
This is the normal cooking state. Before displaying READY, the broiler will go through the PREHEAT
mode; The pre-heat mode lasts until the pre-heat Soak Time expires.
In the On mode, 2 extra conditions may exist: LOW and HIGH. Both depend on the current set point,
and the current temperature. If the difference between the set point and the current temperature
exceeds the programmable thresholds, then either the LOW or HIGH messages are displayed. This warns the user to wait until the READY condition
conveyor. These conditions are likely to occur when a recipe calls for different temperatures.
HOT STATE
This state is active after the broiler is turned Off (or if an error occurs that causes the broiler to shut­down). This state is a cool down step between the On and Off states. The conveyors continue to turn
but the burners are off. The display continuously shows HOT until the Cool Down Time has elapsed, at which point the OFF message reappears.
4. DIAGNOSTICS
This section describes the various diagnostics errors that are available.
BROILER TEMPERATURE PROBES
comes back before putting product onto the
All probes are type-K probes. All temperature readings normally associated with a type-K probe are considered valid by the controller. However, if the probes become disconnected or otherwise open, the controller will sound the buzzer The defective probe number is displayed on the 2nd line: On the broiler controller, there are two thermocouples connected together:
2 is temperature probes
Pressing any button shuts the buzzer off, but will not remove the error message. The only way to remove the error message is to resolve the probe and/or connection problem.
and scroll HOT-PROBE ERROR on the 1st line of the display.
When this heater probe errors occurs, the broiler continues operation, at 100% heat. The operator will most likely then have to adjust the recipe times, but at least the broiler can still operate. Due to broiler construction, 100% heat for any amount of time is not a problem as the broiler will not “burn” or otherwise ignite.
EXTERNAL DC ERROR
The DC I/O connector has a +5VDC supply. This supply is internally protected against over-currents.
Should this occur, the broiler will internally disconnect the supply and report HOT-EXTERNAL DC ERROR. The broiler goes into shutdown (through HOT mode) and the only way to reset this is to
resolve the problem (most likely a short). Since the buzzer is powered through the same +5VDC supply as the DC I/O connectors, the buzzer does not sound when this error occurs.
After the Cool Down delay, the error message becomes OFF-EXTERNAL DC ERROR instead of
HOT-EXTERNAL DC ERROR.
5. EMERGENCY STOP SWITCH
An emergency stop switch is on the front of the broiler as shown in Figure 8. This switch is for

stopping the conveyors and shuts off the gas immediately in case of a conveyor jam or other problem requiring the broiler to shut down.
Do not use this switch for normal shut downs at the end of the day. Use it if the conveyor jams or you need to stop the broiler immediately .This switch stops the conveyors and turns off the burners and turns off power to the control panels. When you turn the Emergency Stop Switch back on, the control
panels will cycle through an initialization, then display OFF. From here you can start as normal.
IV. SCHEDULED MAINTENANCE
CLEANING DURING OPERATION
Grease and Ash removal from Grease Tray.
Use caution when removing the Grease Tray as it will be extremely HOT. DO NOT clean
the Grease Tray in cold water, as cold water will warp the hot Tray. To avoid cooling the broiler down during cleaning, replace the used Grease Tray with a clean one immediately after removing the used one. One spare Grease Tray is included with the Broiler.
DAILY CLEANING PROCEDURES
CAUTION: Do not touch the broiler section immediately after broiler shut-down. The temperature
inside enclosures is in excess of 500°F (260°C), which eliminates the need to clean any parts inside the enclosures for sanitary purposes. Any grease that may build up on the exterior of the enclosures should be cleaned off with a damp cloth and a minimum
amount of detergent. Never use water on the enclosure or allow burner faces to get
wet as this could cause premature burner or gasket failure. Disconnect the power supply to the broiler before cleaning or servicing.
CAUTION: UNDER NO CIRCUMSTANCES SHOULD OVEN CLEANER BE USED ON THIS
BROILER. OVEN CLEANER WILL EAT HOLES IN THE ALUMINUM GAS VALVES AND GAS LINES, CAUSTIC FUMES CAUSE ELECTRICAL COMPONENT DAMAGE, AND WILL CAUSE MANY OTHER PROBLEMS IF USED TO CLEAN THIS BROILER.
CAUTION: DO NOT ALLOW WATER TO CONTACT THE (3) COOLING FANS. DOING SO MAY
CAUSE THE BROILER TO TRIP THE GROUND FAULT RECEPTACLES AND NOT OPERATE. PLEASE COVER THE FANS WITH PLASTIC OR OTHER TO PREVENT.
CAUTION: KEEP THE BROILER AREA FREE AND CLEAR FROM COMBUSTIBLES.
1. Allow broiler burners and chain to operate until the control goes from HOT to OFF after cooking last
patty to burn off excess grease on broiler components. (This applies every time a meat chain is turned off -- regardless of what time of day meat chain is shut down -- and regardless of how few patties were broiled in the last 30 minutes, last hour, etc.) This will clean some parts of the cooking chamber. Failure to perform this procedure daily will result in poor cooking times.
2. Turn off broiler, wait 30 minutes and disconnect electricity.
3. Remove all exterior panels except those which are attached with screws. Be careful not to touch
any hot internal broiler components.

8. Using the conveyor only button on the control which turns the conveyor ON and leaves the heat OFF,
brush the broiler conveyor and, as it cools, wipe with damp cloth.
9. Scrape deposits from the axles with the axle scraping tool, furnished with each machine as shown
below. *THIS IS IMPORTANT TO PREVENT GREASE FIRES AT REAR OF THE BROILER.
Axle Scraper Part Number 100367
The axle scraper provided with the broiler is a handy tool for cleaning the dirt and grime off of the axles. To insert, place end of scraper in between conveyor and turn scraper as shown in the illustration. Scrape the axle back and forth. One end of the scraper is made to scrape a ¾” diameter shaft. The other end of the scraper is made to scrape a 1 1/16” diameter shaft.
10. Remove grease and meat residue from any part of remaining broiler structure where visible. Use a damp cloth with detergent and a putty knife for best results.
11. After cleaning all removable parts as noted, allow to dry and reassemble.
WEEKLY CLEANING PROCEDURES
1. Perform daily cleaning procedures.
2. Inspect igniters for ash and debris buildup (Figure 9, Item 5).
3. Using a small wire brush or sand paper, lightly clean sensor rod and inside of hood only. Use caution the sensor rod and glow plug will break easily!

5. If sensor rod or glow plug does break, the igniter must be replaced. Attempt to light manually, then call service agency.
6. Using a small wire brush and some pressure, brush clean the upper and lower flame runners (Figure 9, Items 2 and 3).
7. Make sure that when cleaning the small ports on the flame runners that all are cleared of any debris buildup.
8. Remove any loose debris from flame runner area.
9. Remove conveyor and soak in hot soapy water overnight. To remove conveyor, lift front axle up to produce slack in the conveyor and separate conveyor at the open link. Using the conveyor only button may be required to locate the open link. If necessary open link with chain pliers (part #500033) to separate conveyor. When replacing the conveyor, make certain the conveyor is installed properly. Make reference to the orientation of the conveyor links and the conveyor direction before reassembly. See Figure 11. PLACING CONVEYOR ON BACKWARD WILL CAUSE SEVERE BINDING PROBLEMS. CLOSE all open links with pliers to match other links.
10. Remove the Drive Shaft Assembly and clean. (See Figure 14)
11. Clean gas orifices:
a) Orifices are passageways directing gas flow into burners. Uneven gas flow or poor air to gas
ratio is caused by dirty or damaged orifices.
b) Orifices are made of brass. Use special care in cleaning--don't gouge or make gas holes
bigger. c) To reach orifices, remove burners. d) Use a chenille stem (similar to a pipe cleaner) or small orifice brush dipped in rubbing alcohol
to clean orifices. Swab until clean; free of carbon build-up. Do not use drill bit; this will
damage the orifices. Chenille stems are available in the craft section of your local
department store or craft store.
MONTHLY CLEANING PROCEDURES
1. Turn off broiler, wait 30 minutes and disconnect electricity.
2. Perform daily & weekly cleaning procedures.
3. Remove roller (drive) chain covers on each side of broiler at exit end. Clean any grease accumulations.

NOTE: If the broiler has two conveyor belts, and you have a TACH ERROR on only one of the conveyors, as
a temporary work around to keep the one working conveyor running you can use the following procedure:
Turn on the broiler using the ON/OFF key. The broiler will start, and you will get a TACH ERROR. The broiler

will go into the HOT mode. Press the ON/OFF key once and the tach error beep will stop, press the ON/OFF key again and the broiler will start the one conveyor that does not have a TACH ERROR. During this operation, the control will still display the TACH ERROR message, but the broiler will not shut down to the HOT mode. This procedure will allow the store operator to continue in operation until a service agency technician can get to the store to fix the problem.
HOT – PROBE ERROR or OFF – PROBE ERROR
Note: The number on the second line of the control display indicates the thermocouple number.
For electric broilers, 1 indicates the top heater thermocouple, and 2 indicates the bottom heater
thermocouple. For gas broilers, which have two thermocouples connected in parallel (which acts as one thermocouple to the
control), the display will indicate 2 When a problem occurs, the first message displayed is HOT - PROBE ERROR. After the cool down period, the broiler will turn off and display OFF – PROBE ERROR.

Failed Thermocouple Replace Thermocouple
Depending on the 6-Recipe Button Control factory setting, some electric broilers will default to 100 percent heater output to allow the broiler to continue to operate until the problem is fixed. In this case, the recipe cook time should be temporarily adjusted to achieve the desired cooked product using the 100 percent heat. A
PROBE ERROR message will be displayed until the problem is fixed.

MODEL 713BG(DB9L,DB9R)/2424G (DB9A) AUTOBROIL
INSTALLATION
Prior to installation of a catalyst equipped conveyor broiler in an existing restaurant, your hood duct and fan system should be cleaned by a professional commercial cleaning service. Refer to Figure 12 and make certain that all parts related to the catalyst are properly installed.
OPERATION
The catalyst is activated by the exhaust heat from the broiler. There are no extra burners to be added or electrical components to be connected in order for the catalyst to work. As long as all parts are properly installed and the broiler calibrated, the catalyst will operate normally. (See broiler owner’s manual for broiler calibration.)
CAUTION: DO NOT TOUCH THE CATALYST IMMEDIATELY AFTER BROILER SHUT DOWN. THE TEMPERATURE OF THE CATALYST IS IN EXCESS OF 500°F (260°C), NEVER PUT WATER ON CATALYST WHILE CATALYST IS HOT. USING WATER ON A HOT CATALYST WILL CAUSE SEVERE WARPING AND MATERIAL DAMAGE.
CAUTION: UNDER NO CIRCUMSTANCES SHOULD SOAP, DEGREASER, OVEN CLEANER OR ANY OTHER CLEANING AGENT BE USED ON THE CATALYST. CLEANERS WILL CAUSE SEVERE DAMAGE.
CAUTION: DO NOT RUN THE CATALYST THROUGH A DISHWASHER. CLEANING
The catalyst washing procedure is a simple three-step process. The vast majority of the fatty acids deposited on the catalyst are water-soluble. Care must be taken to use only clean hot water. Soaps, detergents, bleaches and antioxidants all contain substances which are considered catalyst poisons. In other words, they will render the catalytic converter inoperable. Clean all foreign matter from the wash basin before starting the catalyst washing process. The process is as follows:
1. Partially fill a clean wash basin with about 4” of clean hot water (100-130°F). Set the converter module in the water so that it is completely covered. Let it soak for 15 minutes
2. Remove the module. Shake out the excess water. Drain and rinse the basin thoroughly; then repeat step 1.
3. Remove the module and rinse through the catalyst with a large volume of hot water. The typical
restaurant rinse nozzle is ideal. Work the spray slowly over the entire surface of the catalyst. DO
NOT USE A HIGH PRESSURE HOSE. Shake the remaining water from the converter module and allow to dry as time permits. Reinstall on the broiler. The converter is now ready for normal operation.
4. Rotating the square catalyst from front to back of the broiler when reinstalling the catalyst will extend the life of the catalyst. This means when it is placed on the broiler, the handles in front should now be on the back side of the broiler.
Frequency for the above procedure should follow your normal restaurant procedure for cleaning and sterilization of your food preparation and cooking surfaces but not less than once per week.
