6.2、Debugging

It’s very important to debug the new stove. Through the comprehensive system test of equipment, we can ensure function and safety performance of products. Discovering any potential problems before use (such as equipment’s placement, ventilation, operation, etc), can avoid costly losses.

  1. Safety Notices and Precautions
  • Warning! For your safety, do not place petrol and other flammables nearby. Please keep clean and free of flammables surroundings. (Read ANSI Z83.14B, 1991 for reference)
  • Warning! Any erroneous installation, adjustment and refit may cause property damage or personal injury and maintenance failure. Read the instructions carefully before installation and using.
  • Warning! Operation instruction must be placed in a conspicuous location. When customers smell gas in the process of using, you should take safety precautions immediately. Immediately turn off the main gas valve, extinguish all heat and flames, and call 911. Safety information can be obtained from your local gas suppliers.

    When using this equipment, safety precautions should always be followed, including the following:

  • The griddles burners, grates and outside surfaces may become hot after using, so you must be careful to touch;
  • During operation, do not directly touch burners and plates;
  • Turn off the equipment as not in using, cleaning, servicing or adjusting any parts or attachments.
  • If the equipment has any problems of equipment damage, gas piping leaks, igniter or valves damage, or lose product accessories, do not operate by yourself and call for the service immediately;
  • The attachments not recommended or sold by the manufacturer may cause fire, personal injury, even death;
  • Do not use out of doors;
  • The equipment is used for grill, not available for any other using;
  • The equipment does not contain any user-serviceable parts. Dealers or technicians will repair it. Do not take apart any spare parts without authorization;
  • Never change any other parts without authorization to this equipment, otherwise, may cause hazards, and the manufacturer has the right not to provide warranty service;
  • Steel cutting producers used to manufacture with sharp edges. The manufacturer has dealt with these sharp edges during production, however, we insist the operator take care when in contact with this piece of equipment;
  • Always keep hands, hair and clothing away from heating source.
  • Wait the unit cools down before you cleaning. Because the unit is too hot to handle after using.
  1. Operating Instructions
  • Before operating, make sure place the unit horizontally by adjusting bottom adjustable legs, and place the catch tray properly.
  • The pilot light has been set at the factory. Each burner has a pilot light.

8.1、Lighting the pilot lightTurn the control valve at the position of “0”(Fig.2), make sure all knobs are in the close state. Light and hold an ignition source at the pilots. The pilot light may not be lighted immediately, for existing gas in the pipe. Wait a minute, the pilot light will be lighted after the gas extinguished.

Tips: You can use a screwdriver to adjust the height of the flame (Fig.3).

8.2、Igniting the main burnerRevolve the main fire control valve knob anticlockwise after lighting the pilot light, then the main fire burner is lighted by the pilot light. The power of burner increases as revolving angel increases.When knob reaches to ” “, burner is in the maximum power(Fig.4).

Fig.2                    Fig.3                      Fig.4

  • Make sure air circulation well at the bottom of equipment;
  • Do not use fan or air-conditioning blowing at the flame, in order to avoid extinguishing flame and cause safety accidents;
  • Install the matched cooking fume exhauster according to the local regulations of char broiler;
  • Make sure to keep the natural air circulation in the kitchen.

8.3、Turn off the valve

Revolve the control valve knob clockwise to “0” (Fig.1)to extinguish flame of the main burner, but the pilot light still works.

After turning off the equipment, the main fire should be stop more than 5 minutes before next using.

8.4、Stove Operation

Before using the stove for the first time, please use a mild detergent to wipe it for cleaning. Do not use corrosive or abrasives detergent.

Turn the burners on about 15-20 minutes before broiling for preheating, according to the cooking requirement to adjust the flame size.

Notice: Before first preheating, the furnace will smoke rise. This is because of protective lipids on the grills and other parts are heated, it is normal, and it will be eliminated after the power up to the maximum for burning an hour.

8.5、Exchange main fire nozzle to switch gas source

Remove control panel, grill, the pilot light head, and bottom tightening screw of the end of burner (arc), take out burner, then remove main fire nozzle with proper open spanner, exchange nozzle of another gas source, then screw it (Fig.5). Reinstall burner, the pilot light head, grill and control panel in proper place.

  • Caution: Each main fire nozzle of the burner has been installed before delivery, normal use without adjustment but only switching gas. Adjust only by authorized and licensed technicians. When you change the gas source, you need exchange the corresponding pressure maintaining valve which installed on air intake. See 2 in P16.

8.6、Adjust air input

Remove control panel, unscrew damper solid screw(Fig.6), revolve damper left to right (Fig.7), meanwhile, observe flame and adjust an appropriate opening degree. Then screw damper solid screw, make sure the equipment will not get loose in the process of moving and translation. Reinstall control panel.

  • Caution: Each burner damper has been adjusted before delivery (once air input), normal use without adjustment but only switching gas. Adjust only by authorized and licensed technicians.
