Gas Connection:
NOTE: ALL GAS FITTING MUST ONLY BE CARRIED OUT BY AN AUTHORISED PERSON.
1. The product do not require an electrical connection, as they function totally on the gas supply
only.
2. 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:

-
5
-
a. Gas Type required for the appliance is shown in the rating label. Check that this is
correct for the gas supply the appliance is being installed for. The gas conversion
procedure is detailed in this manual.
b. 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.
c. 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 .
3. 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.
4. 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.
5. Check all gas connections for leakages.
6. Check that the gas operating pressure.
7. Turn off the mains gas supply and bleed the gas out of the appliance gas lines.
8. Turn on the gas supply and the appliance.
Verify the operating pressure remains correct
4.3、Information of Gas Supply and Burner

-
1、Turn ignition control knob anticlockwise from “●” to near “ ”, as
shown in Fig.1.
2、Then press ignition control knob to the bottom and keep pressing it about
10-15 seconds, then turn it anticlockwise till it rings and reaches“ ”.
Release the knob and observe stability of fire, the pilot is ignited and the
equipment is under standby mode. If the pilot is not ignited, please repeat
the steps above until the pilot is ignited. (Fig.2).
(If it is the first time to light up the fryer, it may take longer time for
the gas to flow to the pilot）.
NOTE: There is air in the pipeline when the first time light the fire, then
can normally light the pilot light until flow out air.
NOTE: If the pilot flame were accidentally extinguished, the flame failure
safety device would operate and cut the gas flow to the main burner. It would
then be necessary to relight the pilot by following the above procedure.
8.2 Igniting the main burner
1、After the pilot is lighted, Turn ignition control knob anticlockwise to
“ ”, as shown in Fig.3.Ignite the main burner by the pilot light, turn
temperature control knob to proper temperature according to user demand;
<Table 3>
Setting 1 2 3 4 5 6 7
oC 115 130 145 160 170 180 190
NOTE: When the oil temperature reaches the desirable temperature (normally
at this point of time, the main burner will be temporarily closed).
Ensure there are liquid edible oil or solid shortening in hydro-cylinder
before light the main fire;
Caution: Add oil to fry pot between the maximum and minimum level;
