Gas Connection:
NOTE: ALL GAS FITTING MUST ONLY BE CARRIED OUT BY AN AUTHORISED
PERSON.
The product do not require an electrical connection, as they function
totally on the gas supply only.
It is essential that the gas supply is correct for the appliance to be
installed and that adequate supply pressure and volume are available. The
following checks should therefore be made before installation:
Gas Type required for the appliance is shown in the rating label. Check

- 12 -
that this is correct for the gas supply the appliance is being installed for.
The gas conversion procedure is detailed in this manual.
Supply Pressure required for this appliance is shown in the ‘Gas supply
requirements’ section of this manual. Check the gas supply to ensure
adequate supply pressure exists.
Input Rate of this appliance is stated on the Rating label .The input
rate should be checked against the available gas supply line capacity.
Particular note should be taken if the appliance is being added to an existing
installation.
NOTE: It is important that adequately sized piping runs directly to the
connection joint on the appliance with as few tees and elbows as possible to
give maximum supply volume.
NOTE: Ensure the regulator is converted to the correct gas type that the
appliance will operate on. The regulator outlet pressure is fixed
ex-factory for the gas type .
1. Correctly locate the appliance into its final operating position and using
a spirit level, adjust the legs so that the unit is level and at the correct
height.
2. Connect the gas supply to the appliance through the regulator. A suitable
jointing compound which resists the breakdown action of propane must be used
on every gas line connection, unless compression fittings are used.
3. Check all gas connections for leakages.
4. Check that the gas operating pressure.
5. Turn off the mains gas supply and bleed the gas out of the appliance gas lines.
6. Turn on the gas supply and the appliance.
Verify the operating pressure remains correct

intake-tube;

- 14 -
It may be necessary to adjust the balance of air input by authorized and
licensed 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 or not before using, and forbid using an open flame to test!
After installing completely, you should 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. 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;
●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 2, otherwise, you will need
to adjust gas pressure regulating valve or
contact gas supplier to bargain;
●Unplug pressure gauge after you accomplish
pressure testing, then install needle type
pressure joint screw arbor. Important: must screw joint screw arbor,
to prevent gas escape!
Ensure the pressure and no leaks of the appliance, Check the appliance
shall operate normally without flame lift or light back.
6.2 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.
It is necessary to check the machine daily.
Check the machine regularly can avoid serious accident happens.
Stop using if user feels that there are some problems in the circuit or
machine.
Check the situation of the machine before or after using every day.

8. Operating Instructions
Before operating, make sure to place the unit horizontally by adjusting
bottom adjustable legs, and place the catch tray properly.
To ensure that the air flow in the bottom of the equipment.
Do not use fan or air-conditioning blowing at the flame, in order to avoid
extinguishing flame and cause safety accidents;
Must be installed the matched exhaust hood according to the local
regulations above the equipment.
To ensure that the air in the kitchen is kept in circulation.
The pilot light has been set at the factory. Each burner has a pilot light.
8.1 Lighting the fire（hot plates）
①、Align the control valve knob on the "O" position (Fig.2), so that the valve
is closed.
②、And then axial press the front air valve knob, left 30 degrees, to the
fire position (Fig.3).
③、At the fire position, completely press the knob, meanwhile light the
fire by pilot with another hand. Keep pressing the knob about 10-15 seconds,
and observe stability of fire.
④、If the fire is not lit, please repeat the above steps until the fire
is ignited.
Tip ：The pilot light may not be lighted immediately, for existing gas

- 17 -
in the pipe. Wait a minute, the pilot light will be lighted after the gas
extinguished.
8.2 Igniting the main burner（hot plates）
Revolve the main fire control valve knob anticlockwise after lighting
the pilot light, and then the main fire burner is ignited by the pilot light.
When knob reaches to " " (90 degrees), burner is in the maximum power
(Fig.4). Once again axial press the knob and revolve it anticlockwise, the
power of burner reduces gradually with the rotation angle increases. When
knob is rotated 150 degrees to " ", burner is working with a minimum power
(Fig.5).
8.3 Lighting the pilot（oven）
①、Align the OFF indicative line of thermostat
valve knob to the arrow (Figure 6) to close the
valve.
②、Open the underside panel of oven (figure 7),
thoroughly press the thermostat valve knob to the
bottom, and turn it anticlockwise till it
reaches" "(figure 8), and press the button of the
piezo igniter with another hand simultaneously
( figure 9). There is electric spark between pilot and fire
needle. If the fire is not lit, please repeat this action
until the fire is ignited, and observe stability of fire.
(If it is the first time to light up the oven, it may take longer time
for the gas to flow to the pilot）

Tip ：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.
8.4 Igniting the main burner（oven）
After the pilot was ignited, the main fire valve was opened ，and turn the
thermostat valve knob to the required temperature position，At this moment,
the oven burner is ignited. When reaching the set temperature, the thermostat
valve will automatically adjust the gas flow to keep the temperature in the
oven constant.
8.5 Turn off the valve
1、Hot plates
①When the control knob is rotated to the fire position (Fig.3), the main
fire burner flame is extinguished, but the pilot light will continue to work.
②Axial press the knob to rotate knob clockwise continually, so that the
direction of the knob on the "O" position, at this time, the fire extinguished,
the valve closed. (Figure. 2)
2、Oven
①When the control knob is rotated to the pilot position (Fig.8), the
main fire burner flame is extinguished, but the pilot light will continue
to work.
②Axial press the thermostat valve knob to rotate knob clockwise continually,
Align the OFF indicative line of thermostat valve knob to the arrow (Figure.
6) to close the valve, at this time, the fire extinguished, the valve closed.

8.6 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 above. This is
caused by 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.
8.7 Adjust air input
①Hot plates：Remove the cooking grates and cover, adjust an
appropriate distance to the need, then tighten the damper fastening screws,
to ensure the equipment will not get loose in the process of moving and
translation. Reinstall burner and the cooking grates.
Hot plates Oven
②: Oven: Open the underside panel of oven (figure 7), loosen the
fastening screws of damper(figure 10)
and rotate the damper horizontally
(figure 11). Meanwhile, observe the
flame. Adjust the damper to the
appropriate opening angle. Then,
tighten the fastening screw bolt of
damper to guarantee the appliance does
not get loose. At last, reinstall the
