INSTALLATION
Important
Your attention is drawn to the latest GAS SAFETY (INSTALLATION & USE) REGULATIONS 2000.
This appliance MUST be installed by a competent person in accordance with these and any other relevant
regulations. Users, too, should be aware of the regulations governing the use of gas appliances,
particularly with respect to the need for regular servicing.
Your attention is drawn to the requirement that those parts, which have been protected by the
manufacturer or his agent, are not to be adjusted by the installer.
Before Installation
Before commencing installation, remove all packaging materials from the appliance. It is suggested that
any protective film adhering to the stainless steel panels should be left on until installation is completed.
BUT THIS MUST BE REMOVED BEFORE COMMISSIONING OR OPERATING THE APPLIANCE.
Check the appliance Data Plate (located on the back of the flue upstand/splashback panel), to ensure
that the appliance is suitable for the gas supply available.
Ensure that the floor upon which the appliance is to stand is level and capable of adequately supporting
the weight of the appliance. TO COMPENSATE FOR SOME UNEVENNESS OF THE FLOOR, THE
APPLIANCE FEET ARE ADJUSTABLE.
THE FLOOR MUST BE FIRE PROOF. If it is not, or if any adjacent wall or surface is made of a combustible
material, then the installer MUST ensure that the requirements of the LOCAL FIRE REGULATIONS are
observed.
Positioning
In order for us to meet the stability requirements, this fryer MUST BE FIXED TO THE FLOOR by means of
the fixing holes in the flanged feet. This is not necessary if the fryer is in a suite and therefore fixed to
another appliance.
Place the appliance in position allowing a minimum gap of 150mm (6”) at the rear and at least 150 mm
(6”) between the sides of the appliance and any adjacent wall. The minimum distance between the top of
the appliance and any overshelf or ceiling constructed of a combustible material must be 1525 mm
(60”).
Adequate ventilation is essential for safe operation of a gas appliance. A supply of fresh air is necessary
for the correct combustion of the gas and there must be a means of exhausting the heat and the
products of combustion from the kitchen. It is recommended that the appliance be sited below a
ventilating hood, one preferably connected to an extractor system incorporating a grease filter.

Installation (cont.)
Important Note
These appliances are to be installed with sufficient ventilation to prevent the occurrence of unacceptable
concentrations of substances harmful to health in the room in which they are installed.
The appliance MUST NOT be connected DIRECTLY to a flue or ventilating system, although the flue
products of two or more appliances may be directed into a common outlet when building a suite of
appliances (see separate instructions for suiting appliances).
Ensure that the appliance is level in two places - front to rear and side to side. To check the level it is
recommended that a spirit level be placed on the top of the unit. Level can be achieved by adjusting any
or all of the screw in feet in each corner of the base. Turn anti-clockwise to lower and clockwise to raise
the corner. Warning if the appliance is to be free standing it should be screwed to the floor through the
two front legs to ensure stability.
Gas Connection
Natural Gas: The size of the supply pipe should be no smaller than ½” BSP and an easily accessible
stopcock must be fitted in the gas line adjacent to the appliance.
An armoured flexible pipe of a GAS COUNCIL APPROVED PATTERN is recommended.
NOTE:
Due to the pressure loss through the snap connection fitting on flex hoses you must fit a ¾”
flexible hose to all 600mm wide Twin Basket Fryers
Ensure that all the pipes to the appliance are clean and free from swarf etc, BEFORE making the final
connection.
Propane Gas: Follow the same procedure as that for Natural Gas EXCEPT that the Gas Governor MUST BE
DISSABLED using the Governor exclusion screw, - the Gas Supply Tank or Cylinders are already fitted
with a Gas Regulator.
Leak Test
Clean off any protective film from the stainless steel panels.
AT THIS STAGE, LEAK TEST THE WHOLE SYSTEM. THE GAS SAFETY REGULATIONS require that ALL
connections in the gas supply line between the Gas Meter and the appliance is tested for gas leaks.
THIS MUST BE DONE BEFORE COMMENCING TO COMMISSION THE APPLIANCE.

Installation (cont.)
Checking and Commissioning (cont.)
ALTHOUGH EVERY APPLIANCE IS TESTED AND SET BEFORE IT LEAVES THE FACTORY, IT IS
IMPORTANT THAT THE INSTALLER RE-CHECKS CERTAIN FUNCTIONS BEFORE LEAVING THE SITE.
CHECK THE GAS PRESSURE AT THE APPLIANCE THUS: The pressure test point is behind the compartment door on the Control Valve.
Connect a manometer (U tube) to the test point. Turn on the gas supply and light the appliance. Check
that the pressure reading agrees with that stated on the Data Plate (for Twin Tank models this should
be carried out separately for each tank).
SHOULD ADJUSTMENT BE NECESSARY, PROCEED AS FOLLOWS: On the gas governor: (part of Control Valve). Remove the cap in order to gain access to the pressure
adjusting screw.
Turn the pressure adjusting screw clockwise to increase the pressure or anti-clockwise to decrease it.
When the pressure reading is correct, refit the cap to the governor.
Turn the gas supply to the unit OFF at the stopcock and disconnect the manometer (U tube). Ensure that
the pressure test point screw is refitted.
Turn the gas supply to the appliance on at the stopcock and leak test the pressure test point using a leak
detection fluid.

Use of Solidified Oil or Fat
1)
In an Empty Pan.
IMPORTANT: If solidified oil or fat is to be used, remove the grid from the bottom of the pan,
break the solidified oil or fat into small pieces and fill the V shaped bottom of the pan.
Light the appliance and turn the thermostat knob to 130° C. Continue to add pieces of fat into
the pan until the V shaped bottom is filled with the molten fat. If the fat appears to be
overheating, turn the thermostat OFF, continue to add fat and turn the thermostat ON when the
fat has cooled.
Refit the grid and put the remaining pieces of oil or fat into the pan until the level is up to the
mark. Allow to heat up slowly until all the fat has melted, and then turn the thermostat knob to
the required cooking temperature.
2)
Already Solidified In the Pan.
Light the appliance and turn the thermostat ON for approximately 5 - 10 seconds and then turn
OFF again. Leave it for 30 seconds before repeating the 5 - 10 seconds cycle.
Continue to repeat until the fat has melted so that any remaining un-melted pieces are free
floating, and then turn the thermostat to the required temperature.
Cooking Instructions
With the thermostat knob turned to the required cooking temperature, allow the oil or fat to heat up for
about 20 minutes before starting to cook. After each load is removed from the fryer always allow 2 ½
minutes for the temperature of the oil to recover before the next load is put into the oil.
The Frying Medium
Ensure oil is always maintained at the correct level indicated and neither under or over-filled.
The attention of the user is also drawn to the risks due to replenishment of the oil when the fryer is hot.
Good quality vegetable oil is recommended.
The life expectancy of oils will be lengthened if they are filtered regularly - food particles not removed turn
rancid and reduce oil quality. The life of the oil will also be extended if the temperature is turned down
when the fryer is not in use.
“Please note also, using old oil will reduce the flash point and therefore present a greater fire hazard and
be more prone to surge boiling. Attention shall also be drawn to the effect of over-wet food and too
large a charge on surge boiling”. Hot oil is dangerous; it must not be handled until it has cooled to a safe
temperature.

Cleaning
It will be found that it takes less time and effort if appliances are cleaned every day, particularly while
they are still warm and before grease and spillages are burnt on.
PROPRIETARY OVEN CLEANER MUST BE USED WITH CARE; THEY ARE HIGHLY CORROSIVE AND MAY
CAUSE DAMAGE TO SURFACES AND COMPONENTS.
Clean stainless steel with soap and hot water or a mild detergent solution. Rinse and dry thoroughly.
DO NOT USE CAUSTIC OR ABRASIVE CLEANERS, DO NOT USE ABRASIVE PADS.
DO NOT USE flammable solvents and cleaning aids
NOTE! Carbon will build up as part of the natural cooking process on the inside of the Fryer tank and is
not detrimental. The carbon build up can be kept to a minimum by regular cleaning and boiling with a
soapy water solution.
Daily Cleaning
1)
2)
Turn the gas control valve to OFF.
Screw the drainpipe into the drain valve. Place a suitable container with a filter below the drain
tap, remove the safety chain and open the tap.
NOTE: The oil or fat will flow more freely if it is still warm but on no account should the fat be
filtered at frying temperatures.
3)
Remove the frying basket and also the strainer from the bottom of the pan and clean these
4)
Clean the inside of the pan with a clean cloth, taking care not to damage the two thermostat
thoroughly at the sink.

SERVICE AND MAINTENANCE
Maintenance MUST only be carried out by a competent person. Ensure that the gas and electricity supply
to the appliance has been turned “OFF” before dismantling any components.
Routine Maintenance Procedure
1)
Ensure that the Fryer pan is filled with oil.
2)
Fit a manometer (U tube) to the pressure test point on the gas control valve and go through the
lighting procedure. Check that the flame safety device opens from cold in no more than 10
seconds
3)
Turn the thermostat to 150°C and check that the pressure at the test point is: Natural Gas -
15 mbar (6” w.g)
Propane Gas - 37 mbar (14” w.g)
Adjust if necessary the governor - on the control valve. (For Twin Tank models this should
be carried out for each tank separately).
NOTE: Only leave the burners on for the minimum amount of time to ensure that the fryer does
not get too hot.
4)
Turn the thermostat to OFF and ensure that both burners extinguish completely within
3 - 4 seconds.
5)
Turn the thermostat on again to 150°C and ensure that both burners cross light smoothly from
6)
Check that the burner flames are uniform and there is no spillage of the flames away from the
the pilot.
heat exchanger.
7)
Turn the thermostat OFF and blow out the pilot. Check that the flame safety valve closes within
8)
Turn off the gas, remove the pilot and withdraw the burner assembly. Clean the burner parts and
60 seconds this can be done by feel or sound.
ensure the injectors are clear.
9)
Ensure that all the flue ways are clear.
10)
Reassemble the pilot and main burners.
11)
Go through the lighting procedure, turn the thermostat to 150°C and allow to heat up. Check
that the thermostat cuts off the gas. Turn the thermostat knob to 190°C allow to heat up and
note the oil temperature is 180°C when the thermostat shuts off the burners. The oil
temperature will overshoot to approximately 190°C.
NOTE! Position the digital thermometer probe for thermostat testing in the centre of the fryer
tank and the tip of the probe must be 25 mm (1”) below the surface of the oil. Turn the
thermostat off.

To Check Override Thermostat
During this check the temperature of the oil in the tank will reach up to 230°C and the greatest care
must be taken. It is preferable that old oil is used, as the oil will not be suitable for frying after the test.
12)
Re-heat the oil in the tank to 190°C.
13)
With the thermostat set to 190°C, short out the thermostat (either by bridging across its contacts
or by bridging across the valve contacts TP/TH & TH) the burner will re-light; allow to heat up
carefully checking the oil temperature with a thermometer.
NOTE: That the over heat thermostat operates between 217°C and 223°C and that the gas to the main
burners goes out immediately. ENSURE THAT THE OIL TEMPERATURE DOES NOT EXCEED 230°C
INCLUSIVE OF OVER-SHOOT.
14)
Remove the link wire from the operating thermostat.
15)
Allow to cool and press the reset button on the overheat thermostat.
16)
Turn on the thermostat and ensure that it operates and turns the gas to the burners on and off.
17)
Check all gas joints for gas leaks with leak detector fluid.
18)
Ensure there are no leaks from the drain valve and replace the old oil, after wiping out the fryer
to remove any stains.

Fault Finding
Fault
Pilot will not establish.
Possible Cause
High Limit Thermostat has tripped
Remedy
Reset high limit thermostat. Check
calibration of operating thermostat, as this
may be too high causing the high limit to
trip. Operating thermostat should cut off
the main burners at 180ºC when set to
maximum temperature. If operating
thermostat calibration is satisfactory, check
high limit thermostat calibration as this may
be set too low causing it to trip or become
sensitive to vibration. High limit thermostat
should cut at approx. 223ºC +0 ºC -12 ºC.
The oil temperature must not overshoot
above 230ºC.
