Ⅲ.OFG321-322 model Gas Open fryer operation methods
1. Gas open fryer combustion controlling system
This system adopts the liquefied petroleum gas, natural gas, and artificial
gas as heat source, by using the four in one gas control valve (open fryer,
thermocouple, electronic lighting and gas volume adjustment) temperature
controller and gas solenoid valve. In order to achieve a safety and reliable

combustion controlling system, you can ignite the purpose-made M mould’s
furnace end electrically, constant temperature controlled, flameout protection
as well as the heat power adjustment.
The principle of operation is as following: ignite by hand pressing to the
piezoelectric conduction type igniter, which can transmit the instantaneous
high pressure to the ignition probe and make it electric discharging by a certain
electric space, then light the gas by electric spark and ignite the open fire. Heat
the thermocouple by igniting the open fire’s flame and thermoelectric effect will
be produced by heating thermocouple, which can open the gas switch
automatically and supply the gas to the burner. The open fire flame which
equipped on the furnace end will light on the furnace end completely and then
you can adjust the gas adjustment valve to make the fire burning normally. If
the equipment’s actual temperature exceeds the setting temperature, the
temperature controller will turn off the gas solenoid valve automatically and the
burner stops burning for the lack of gas. If the temperature is lower than the
setting temperature, the temperature controlling system will give a new order
and the gas solenoid valve open automatically. Now the gas is opened and it is
burning again. The machine controls the temperature automatically by working
like this way again and again.
In order to prevent the danger caused by gas leakage of accidental flameout
of gas burner, the constant open fire structure is adopted and it can ignite the
burner in time. As long as the open fire is not flameout, the burner can be burnt
normally. If the open fire is flameout unexpectedly, the thermocouple can‘t be
heated, the thermoelectric effect will become invalid. To be safely controlled,
the gas adjustment valve will close automatically.
This system is simply operated, reliable, economical and safe. It can be
used widely for automatic controlling of gas heating equipment.
2. Technical parameters
Voltage: ～220V50Hz
Gas type: liquefied petroleum gas, natural gas, pipeline gas
Gas pressure: 2800Pa
Maximum working temperature: 200℃
3. Operation Instruction(program’s setting please refer to the controlling panel
instruction on 8-11 page)
Connect the equipment with gas pipeline when the handed gas valve is
totally closed. Make sure all the joints are sealing well and open the gas switch
when there is no gas leakage. A few second later, press the electronic igniter
button and turn round anticlockwise. Refer to chart 1 and chart 2

图2 chart 2 OFG-322 Diagram
When you hear clicking sound, it shows it is ignited and now the open fire
should be on fire. Press the button a few minutes, then the open fire should be
burning normally. Now the thermocouple on the open fire of the burner will
keep burning (If it can’t be lighted for one time, you can ignite it for two or three
times. If it can’t be ignited for several times, there may some problems with the
gas circuit and the igniter device. When it is lighting, turn round the button
anticlockwise and adjusts the fire to keep the flame on the burner in a vigorous
state.
chart 3 chart 4

The oil drain valve must be turned off when ignition.
1.The temperature will rise steadily when it is burning normally. When it gets to
the setting temperature, you can put into the food for frying. The time for frying
is depended on the food you fry. One fryer can hold two baskets, so you can fry
different food at same time. The time for frying different food is different, so you
can set two different times on the two timers in the controlling panel.(each
controlling panel has 6 keys). It is working properly in the setting time.
