EVACUATION OF EXHAUST FUMES

The appliances must be placed in premises from which exhaust fumes can be evacuated in compliance with installation standards Our appliances are classified type A and cannot be connected to an exhaust fume pipe. The exhaust fumes must be evacuated via extraction hoods or similar devices that are connected to an efficient flue or else they must be evacuated directly to the outside at a rate that does not fall below the specified minimum rate In all cases, if the exhaust fumes are removed through forced evacuation, aspiration must be interrupted if the aspiration value falls below the specified limit The gas supply must be stored to the burners manually.

CONNECTING GAS

INSTALLATION INSTRUCTIONS

Installation operations, adaptations to other types of gas, commissioning and the elimination of system faults must be carried out only by qualified personnel in accordance with current rules and standards The gas systems, wiring and premises in which the appliances are installed must comply with current rules and standards In particular, the air supply for burner combustion must be 2m3/h per kW of installed power Accident prevention, fire prevention and anti-panic measures in businesses open to the public must be complied with.

CHECK BEFORE INSTALLATION

• Check on the rating plate on the left-hand side that the appliance has been tested and approved for the type of gas that the user uses
• Check that the nozzles on the appliance are suitable for the available gas supply
• Check on the rating plate that the pressure reducer is adequate to the appliance’s gas supply (Fig 2)
• The appliance has been set in the company to use a 20-mbar G20
• Do not reduce the diameter of the section between the reducer and the appliance Fit a gas filter above the pressure adjuster in order to ensure optimum operation

CHECKING THERMAL POWER

During initial installation and during maintenance or adaptation to another type of gas nominal heat input must be measured. It can be measured by using the volumetric method with the aid of a litre counter or a chronometer After checking connection pressure and the diameter of the burner injectors, measure the hourly flow of the gas and compare the recorded value with the value set out in the specifications table under the heading “gas consumption” Deviation of± 5% from nominal value is permitted

The appliance must be supplied with one of the types of gas whose properties and pressure are set out in the table below:

Connect the appliance to a special gas pipe with an internal diameter of at least 16 mm for G1/2″ connections and a diameter of at least 20 mm for G3/4″ connections. The coupling must be metal and the pipe may be rigid or flexible. Make sure that the flexible metal pipe that is fitted to the gas coupling does not touch overheated parts of the fryer and is not twisted Use fixing clips that comply with installation standards Fit stopcocks or gate valves whose internal diameter is not less than the above connecting pipe. After connecting the pipe, make sure that the joints and couplings have no leaks Use soapy water or a purpose-designed foam product to detect leaks NEVER USE NAKED LIGHTS.

CHECKING GAS PRESSURE

Gas supply pressure must be measured at the pressure point (Ref P) after removing the sealing screw . Use a flexible pipe, connect a gauge e g a liquid gauge that is accurate to 0.1 mbar) to the pressure point (and measure the intake pressure whilst the appliance is operating. If the pressure reading does not fall within the upper and lower limits indicated on the table, the appliance cannot be installed. Switch off the appliance, disconnect the gauge and close the seal screw and contact the gas company to test main gas supply pressure. A pressure adjuster may have to be fitted upstream of the appliance.

CONNECTING TO A DIFFERENT TYPE OF GAS

ADJUSTING PRIMARY AIR SUPPLY Y TO MAIN BURNER

• Unscrew the bolt (Ref D) that fixes the bush that adjusts the primary air supply (Ref C)
• Position the bush (Ref C) at distance “X” according to the type of gas installed (see ‘Primary air’ on the specifications table)
• Tighten the fixing bolt again (Ref D)
• Seal the adjusted part with tape to prevent tampering

N.B.: the primary air supply has been correctly adjusted when it can be guaranteed that the flame will not detach itself when the burner is cold and if there is no blow-back when the burner is hot

REPLACING THE PILOT BURNER NOZZLE (Fig 5)

• Unscrew screwed-on cap (Ref 1), remove the nozzle (Ref 2) and replace it with one that is suitable for the type of selected gas
• Refit the screwed-on cap (Ref 1)
• Use a foam product to check that the cap does not leak

After converting or adapting for the gas, the plate specifying the type of nozzles used MUST be affixed above the rating plate

Before delivering the appliance to the user:

• check that it operates correctly,
• instruct the user on how to use it

OPERATING INSTRUCTIONS

The appliance must be used only for the purpose for which it was designed Any other use is improper During operation, supervise the appliance

COMMISSIONING

_ WARNING: _do not start up the appliance before filling the frying compartment with oil Failure to comply with this requirement result in grave damage from an overheated frying compartment and overheated healing elements

Before starting up the appliance for the first time remove all the packing and thoroughly clean the protective industrial grease from the tray and containers using this procedure:

• fill the tank to the brim with water and normal detergent, turn on heat and boil for a few minutes.
• drain the water through the drain tap and rinse the tank with plenty of clean water;
• shut off the tap and pour in frying oil above the MIN mark and below the MAX mark

SETTINGS

WARNING

Old oil catches fire at a lower temperature and makes froth that tends to boil over. Remember that placing food that is too moist and placing too much food in the fryers contributes to the formation of froth that may boll over

SWITCHING ON PILOT LIGHT (Fig 9)

• Open gas valve behind appliance
• Turn temperature adjusting knob
• Open door of appliance
• Press the pilot-light button until the pilot light comes on and at the same time press the ON pushbutton for about 20 seconds until all the air has left the pipe and the pilot light is burning
• Check that the pilot light is on with the appliance door open and light the main burner

LIGHTING THE MAIN BURNER AND ADJUSTING TEMPERATURE
