Hotpoint G640 Gas Connection for Cooktop, Gas Connection to Non-flexible Pipe copper or steel

Installation Instructions for your built-in Hob

When installing the hob above a built-in oven without forced ventilation, ensure that there are air inlets and outlets for ventilating the interior of the cabinet adequately.

Gas Connection for Cooktop

The hob should be connected to the gas supply by an authorized 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 tanks must be carried out according to the safety standards currently in force, and only after it is ascertained that it is suitable for the type of gas to be used. If not, follow the instructions indicated in the section entitled, “Adapting the hob for Different Types of Gas”. If the hob is to be connected to tanks containing liquid gas, use pressure regulators that comply with current safety standards.

Important: To insure that the appliance operates safety, the gas is regulated correctly and your appliance lasts over time, make sure that gas pressure levels comply with the indications given in Table 1, “Nozzle and Burner Specifications”.

Gas Connection to Non-flexible Pipe (copper or steel)

Connection to the gas source must be done in such a way as to not create any stress points at any part of the appliance.

The appliance is fitted with an adjustable, "L" shaped connector and a gasket for the attachment to the gas supply. Should this connector have to be turned, the gasket must be replaced (supplied with the appliance).

The gas feed connector to the appliance is a threaded, male 1/2" connector for round gas pipe.

Gas Connection to Flexible Steel Pipe

The gas feed connector to the appliance is a threaded, male 1/2" connector for round gas pipe. Only use pipes, tubes and gaskets that comply with current safety codes. The maximum length of the flexible pipes must not exceed 2000

mm.Once the connection has been made, ensure that the flexible metal tube does not touch any moving parts and is not crushed.

Check the Seal

Once the hob has been installed, make sure all the connections are properly sealed, using a soapy water solution. Never use a flame.

Adapting the Hob for Different Types of Gas

To adapt the hob to a different type of gas than that for which it was designed, (see the sticker under the hob or on the packaging), the burner nozzles must be changed, as follows:

•Remove the pan supports and slide the burners out of the hob.

•Unscrew the nozzles using a 7mm socket wrench and replace them with those for the new type of gas. (See Table 1, “Burner and Nozzle Specifications”).

•Reassemble the parts following the instructions in reverse order.

•On completing the operation, replace the old rating label

with the one showing the new type of gas; the sticker is available from our Hotpoint Service (see KEY CONATCTS, back page).

If the gas pressure is different than that prescribed, a pressure regulator must be installed at the source, in compliance with national standards governing the use of piped gas regulators.

Regulation of Air Supply to the Burner The burners do not need a primary air regulator.

Minimum Regulation

•Turn the gas valve to minimum.

•Remove the knob and turn the regulator screw (positioned either on the side of the top or inside the shaft) clockwise until the flame becomes small but regular.

N.B.: In the case of liquid gas, the regulation screw must be fully screwed in (clockwise).

•Make sure that, when the knob is turned rapidly high to low, the flame does not go out.

•In the event of a malfunction on appliances with the

security device (thermocouple) when the gas supply is set at minimum, increase the minimum supply levels using the regulator screw.

Once the adjustment has been made, apply sealing wax, or a suitable substitute, to the old seals on the by-pass.
