Operating Instructions

Before operating, make sure to place the unit horizontally by adjusting the bottom adjustable legs, and placing the catch tray properly.
The pilot light has been set at the factory. Each burner has a pilot light.

Lighting the pilot light

Turn 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 lit after the gas is extinguished.
- Tips: You can use a screwdriver to adjust the height of the flame (Fig.3).

Igniting the main burner

Revolve 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 the burner increases as the revolving angle increases. When the knob reaches” “, the burner is in the maximum power (Fig.4).
Make sure air circulation at the bottom of the equipment;
Do not use a fan or air-conditioning to blow at the flame, to avoid extinguishing the flame and causing safety accidents;
Install the matched cooking fume exhauster according to the local regulations over the charbroiler;
Make sure to keep the air natural circulation in the kitchen.

Turn off the valve

Revolve the control valve knob clockwise to “0” (Fig.1), so that extinguish the flame of the main burner, but the pilot light still works.
After turning off the equipment, the main fire should be stopped more than 5 minutes before the next use.

Stove Operation
Before using the stove for the first time, please use a mild detergent to wipe it clean. Do not use corrosive or abrasive detergent.

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

Notice:
When first preheating, the furnace will smoke above. This is caused by protective lipids on the grates and other parts being heated, it is normal, and it will be eliminated after the power is up to the maximum for burning an hour.

Exchange main fire nozzle to switch gas source
Remove the control panel, cooking grates, pilot light head, and burner, remove the main fire nozzle with a proper open spanner, exchange the nozzle of another gas source, and then screw it. Reinstall the burner, the pilot light head, the cooking grates and the control panel in proper order.

Caution:
Each main fire orifice 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 converse the gas source, exchange the corresponding pressure-maintaining valve which is installed on the air intake. See 2 in P17.

Adjust air input

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

Cleaning and Maintenance

Do not use any abrasive or flammable detergent to wipe;
Do not hose down, immerse or pressure wash any part of the cooker, excluding the catch tray;
Do not use abrasive cleaning matters to wash, even not use corrosive detergent!
Warning: Before cleaning, all control valves must be turned off. Strictly follow the lighting instructions to work again after cleaning!
Warning: Wait for the equipment to cool down after the unit has been turned off before you clean!
