INSTALLATION
e.g. an open window or a more efficient ventilation system by increasing the extraction power of the electric fan if installed. Liquid petroleum gas descends towards the floor as it is heavier than air. Apertures in the outside walls in rooms containing LPG cylinders should therefore be at floor level, in order to allow any gas from leaks to be expelled. Do not store LPG cylinders (even when empty) in basements or rooms below ground level; it is advisable to keep only the cylinder in use in the room at any one time and connected far from heat sources which could raise its temperature to above 50 °C.
Gas connection for the gas hob
The hob should be connected to the gas supply by a CORGI registered installer. During installation of this product it is essential to fit an approved gas tap to isolate the supply from the appliance for the convenience of any subsequent removal or servicing. Connection of the appliance to the gas mains or liquid gas must be carried out according to the prescribed regulations in force, and only after it has been ascertained that it is adaptable to the type of gas to be used. If not, follow instructions indicated in the paragraph headed, 'Adapting to different types of gas'.
In the case of connection to liquid gas, in a cylinder, a pressure regulator, that conform to the regulations in force, must be inserted.
Important: for safety, for the correct regulation of gas use and long life of the appliance, ensure that the gas pressure conforms to the indications given in table 1, 'Burner and Nozzle Specifications'.
Connection to
Connection to flexible steel tube
The gas feed connector to the appliance is a threaded, male 1/2" connector for round gas pipe. Only use pipes and sealing gaskets that conform to the standards currently in force.
•it should be as short as possible, with a maximum length of 1.5 metres;
•it should not be bent or kinked;
•it should not be in contact with the rear panel of the appliance or in any case with parts which may reach a temperature of 50°;
•it should not pass through holes or slits used for dis- charging the oven flue gases;
•it should not come into contact with pointed parts or sharp corners;
•it should be easy to inspect along its entire length in order to be able to check its condition;
•it should be replaced before the date printed on the actual pipe.
Check the seal
Upon completion of installation, check for leaks from the gas circuit using a soapy water solution (never use a flame). Make sure that the natural gas pipe is adequate for a sufficient supply to the appliance when all the burners are lit.
Adapting to different types of gas (instructions for the hob) To adapt the hob to a different type of gas from the factory- set one (indicated on the rating plate at the top of the hood or on the packaging), the burner nozzles should be
replaced as follows:
•Remove the pan supports and slide the burners off their seats.
•Unscrew the nozzles (fig. 9, using a 7 mm socket spanner and replace them with nozzles for the new type of gas (see table 1 "Burner and nozzle specifications").
•Reassemble the parts following the above procedure in the reverse order.
•On completion of this operation, replace the old rating label with the one indicating the new type of gas used. This sticker is available from Hotpoint Service (see KEY CONTACTS, back page).

Adjusting the primary air of the burners
The primary air of the burners does not need to be adjusted.
Adjusting the low flame
•Turn the tap to the low flame position;
•Remove the knob and turn the adjusting screw, situated to the right of the tap (fig. 10) until you obtain a regular small flame, using a screwdriver (loosening the screw increases the height of the flame, tightening decreases it).
N.B.: In the case of liquid gas, the regulation screw must be screwed in all the way.
•Having obtained the low flame setting required and with the burner lit, change the position of the knob several times from minimum to maximum and vice versa and check that the flame does not go out.
•In appliances fitted with the safety device (thermocouple), should the device fail to work with the burners set to the low flame setting, increase the low flame setting of the same on the adjusting screw.
Once the adjustment has been made, remount the seals on the
