Lighting the Pilot BurnersB.
The burners of this Gas Hob are fitted with individual standing pilots, which allows the main
burners to be turned ON or OFF without the need to manually re-light the burner each time
that it is turned OFF, as the burner will automatically lit itself by the pilot burner.
Flame Failure Protection is incorporated for each burner by way of a thermo-electric system
which will shut off the gas supply to that burner in the event that the pilot burner flame goes
out, so that un-burnt gas is not expelled to the surroundings.
1. Select the pilot to be lighted.
2. Depress the gas control knob and turn it counter-clockwise to “PILOT”.
3. While the knob is depressed, light the pilot burner. Once the pilot has been lit, hold the knob
depressed for 10-20 seconds after lighting the pilot burner. This is to give ample time to heat
up the thermocouple, and allow gas to flow into the gas valve.
4. Release the knob after 10-20 seconds. The pilot burner should stay lit, if not, repeat Steps (1
to 3 above).
5. If pilot burner was extinguished during normal operation, wait for 5 minutes before lighting it
up.
Lighting the Main BurnersC.
1. Select the burner to be lighted.
2. Full flame can now be achieved by depressing the knob a little and turning it counter-
clockwise to the first stop, “HIGH” flame position.
3. To achieve simmer control, depress the knob a little and turn it further counter-clockwise to
the second stop “LOW” flame. Note that the gas control knob can be rotated between “HIGH”
and “LOW” flame to achieve your desired flame height.
Turning “OFF” the Main BurnersD.
1. Select the burner to be turned “OFF”.
2. To turn off the main burner, but keep the pilot burner lighted, rotate the gas control knob
clockwise to “PILOT” position. Notice that the main burner will extinguish and the pilot will
remain lit.
3. It is recommended to turn “OFF” the main burners during idle periods, but let the pilot stay lit.
Turning “OFF” the Pilot BurnersE.
1. Select the Pilot Burner to be turned “OFF”.
2. To turn OFF the pilot burner, rotate the gas control knob clockwise to “ l” position. Notice
that the pilot burner will extinguish.

12
Main burner air supply:F.
1. For efficient burner operation, a proper balance of gas volume and primary air supply must be
maintained which will result in complete combustion. Insufficient air supply results in a yellow
streaming flame. Primary air supply is controlled by an air shutter on the front of the burner.
2. Loosen the lock screw and adjust the air shutter to just eliminate the yellow tips of the burner
flame. Lock the air shutter in place by tightening the screw.
VERY IMPORTANT!
It is highly recommended to contact your authorized service personnel so that the
appliance is serviced immediately when abnormal conditions, such as, partial or full loss of
burner flame, abnormal burner flame, and other burner control problems arise. When such
abnormal conditions were noticed, it is highly recommended not to use or operate the
equipment until it has been serviced and commissioned properly by an authorized service
personnel.
Important remindersG.
1. Components protected by the manufacturer or his agent shall not be adjusted by the
user/operator.
2. The space between the legs at the bottom admits combustion air. DO NOT BLOCK THIS SPACE.
3. All burners are lit from constantly burning pilots. Turning the valve to the desired flame height
is all that is required to put the unit in service.
4. Do not permit fans to blow directly at the unit. Wherever possible, avoid open windows next
to the units' sides or back. Avoid wall type fans which create air cross-currents within a room.
5. It is also necessary that sufficient air should be allowed to enter the room to compensate for
the amount of air removed by any ventilating system. Otherwise, a subnormal atmospheric
pressure will occur, affecting operation and causing undesirable working conditions.
6. A properly designed and installed hood will act as the heart of the ventilating system for the
room or area in which the unit is installed, and will leave the unit independent of changing
draft conditions.
7. All valves must be checked periodically. This must be done by an authorized service
representative in your area.
8. Please wait at least 15 seconds to restart the main burners to maintain the best function of
the safety gas valve after turning off the main burners.
