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. Steps are as following:
●Remove top panel, and needle type
pressure joint screw arbor (Fig.1), then
slip rubber tube of pressure gauge over
needle type pressure joint;

8. 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.
8.1、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 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 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 burner increases as revolving angel increases. When knob reaches
to " ", burner is in the maximum power (Fig.4).
Fig.2 Fig.3 Fig.4

Remove control panel, cooking grates, the pilot light head, and burner,
remove main fire nozzle with proper open spanner, exchange nozzle of another
gas source, then screw it. Reinstall burner, the pilot light head, cooking
grates and 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 installed on
air intake. See 2 in P18.
8.6、Adjust air input
Remove control panel, unscrew damper solid screw(Fig.6), revolve damper
left to right (Fig.7), meanwhile, observe flame, to 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.
