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.
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 light immediately, for existing gas in the pipe. Wait a minute, the pilot light
will light once the gas is extinguished.
Tips: You can use a screwdriver to adjust the height of the flame (Fig.3).
Lighting the main burner
Revolve the main fire control valve knob counterclockwise after lighting the
pilot light, the main fire burner is lit by the pilot light. The power of burner
increases as revolving angel increases. When knob reaches to " ", burner is at
the maximum power (Fig.4).
Fig.2 Fig.3 Fig.4
Make sure there is air circulation at the bottom of equipment;
Do not use fan or air-conditioning towards the flame, in order to avoid
extinguishing flame, and cause safety accidents;
Install the matched cooking fume exhauster according to the local regulations
over the char broiler;
Make sure to keep natural air circulation in the kitchen.

- 12 -
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 out more than 5
minutes before next use.
Stove Operation
Before using the stove for the first time, use a mild detergent to wipe clean.
Do not use corrosive or abrasive detergents.
Turn the burners on 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. This is because of
protective lipids on the grates and other parts are heated, it is normal, and it will
be eliminated after using maximum burning power for an hour.
One side of the grate has a grease trough (Fig.5), and the other side of the
grate is flat (Fig.6), users can choose a side according to demand, users also can
adjust grate’s slope according to demand (Fig.7). The side of grate with the
grease trough should be up if cooking food with more oil, oil will drop into grease
trough, then flow into catch tray.

fire nozzle with proper open spanner, exchange nozzle of another gas source,
then screw it (Fig.8). Reinstall burner, the pilot light head, cooking grates 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
