8. 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 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、Lighting the main burner
Revolve the main fire control valve knob counterclockwise 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 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 over the char broiler;
Make sure to keep natural air circulation in the kitchen.
8.3、Turn off the valve
Revolve the control valve knob clockwise to "0" (Fig.1), so that
extinguish flame of the main burner, but the pilot light still works.
- 10 -
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 clean. 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: When first preheating, the furnace will smoke rise. This is
because of protective lipids on the grates and other parts are heated, it
is normal, and it will be eliminated after the power up to the maximum for
burning an hour.
One side of grate with grease trough (Fig.5), and on the other side of
grate is flat (Fig.6), users can choose a side according to demand, users
also can adjust grate’s gradient according to demand (Fig.7). The side of
grate with grease trough up if roasting food with more oil, and oil will drop
into grease trough, then flow to catch tray.
Fig.5 Fig.6 Fig.7
8.5、Exchange main fire nozzle to switch gas source
Remove control panel, grate and heat storage plate, 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.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 authorized and licensed technicians. When you converse the gas source,
exchange the corresponding pressure maintaining valve which installed on air
intake. See 2 in P17.
8.6、Adjust air input
Remove control panel, unscrew damper solid screw(Fig.9), revolve damper
left to right (Fig.10), meanwhile, observe flame and adjust an appropriate
opening degree. Then screw damper solid screw, make sure the equipment will
- 11 -
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.
