technicians;
Thread glue must be resistant to the action of liquefied petroleum gases.
Warning! Use soap water or testing instrument to test whether piping joint leaks
before use, and forbid using an open flame to test!
After installing completely, check gas supply pressure. Use a pressure gauge which is
equipped with liquid (such as U-type pressure gauge, the minimum value is 0.1mbar) or
a digital pressure gauge to test.

- 9 -
Steps are as follows:
●Remove top panel, and needle type pressure
joint screw arbor (Fig.2), then slip rubber tube
of pressure gauge over needle type pressure
joint;
●Start the equipment in accordance with the
instructions, measuring gas supply pressure
(dynamic pressure) in the work state;
●Access to the equipment if measured data
within the limits of Table 1, otherwise, you will
need to adjust gas pressure regulating valve or
contact gas supplier to bargain; Fig.2
●Unplug pressure gauge after you accomplish pressure testing, then install needle
type pressure joint screw arbor. Important: make sure to screw the needle
valve to prevent gas escape!
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.

Operating Instructions
Before operating, make sure to 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.3), 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 after the
gas has extinguished.
Tips: You can use a screwdriver to adjust the height of the flame (Fig.4).
Igniting the main burner
Turn the main fire control valve knob counter clockwise after lighting the pilot light,
and then the main fire burner is lit by the pilot light. The power of the burner increases
as angle increases. When knob reaches to " ", burner is at maximum power (Fig.5).
Fig.3 Fig.4 Fig.5
Make sure there is air circulation at the bottom of equipment;
Do not use fan or air-conditioning blowing toward the flame, in order to avoid
extinguishing flame and causing safety accidents;
Install the matched cooking fume exhauster according to the local regulations over
the char broiler;
Make sure to keep the natural circulation in the kitchen.

- 12 -
Turn off the valve
Turn the control valve knob clockwise to "0" (Fig.3), to extinguish flame of the main
burner, but the pilot light still works.
After turn 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, please 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 above. This is caused by
protective lipids on the grates and other parts are heated, it is normal, and it will be
eliminated after it is at maximum power for an hour.
One side of grate with grease trough (Fig.6), and on the other side of grate is flat
(Fig.7), users can choose a side according to demand. Users also can adjust grate’s slope
according to demand (Fig.8). The side of grate with grease trough up if roasting food
with more oil, the oil will drop into grease trough, then flow to catch tray.

Exchange main fire nozzle to switch gas source
Remove control panel, grate, vesuvianite, the barbecue frame and fire shield,
remove the pilot light head, and bottom tightening screw of the end of burner (arc), then
remove main fire nozzle with proper open spanner, exchange nozzle of another gas
source, then screw it (Fig.9). Reinstall burner, the pilot light head, fire shield, the
barbecue frame, vesuvianite, grate and control panel in proper place.
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 installed on air intake. See 2 in P19.
Adjust air input
Remove control panel, unscrew damper solid screw (Fig.10), revolve damper left to
right (Fig.11), 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.
