Gas connection

Cat: II 2H3+

The fitting (fig. 17) is made up of:

–1 nut “A”

–1 elbow fitting “C”

–gasket “F”

Connection to the Gas Supply

–Be careful when flexible pipes are used that they do not come into contact with moving parts.

–To maintain the thickness of 3 cm, the hob is fitted with a channel to contain the connection pipe.

–The gas inlet union can be turned in the direction required after the elbow fitting “C” and nut “A” connection (figure 17) has been slackened (fig. 18).

–Never put it in the horizontal or vertical position.

–Never attempt to turn the elbow “C” without having first slackened off the relative lock nut “A”.

–The gasket “F” (fig. 17) guarantees the seal of the gas connection. It is recommended that it be replaced whenever it shows even the slightest deformation or imperfection.

–Using a suitable leak detection fluid solution (e.g. Rocol) check each gas connection one at a time by brushing the solution over the connection.

If installation is to be carried out using a flexible connector (to BS669), then the following points must be adhered to:

Note: The gas installation pipes and the final connection to the appliance connecting pipe shall be sufficient size to maintain the heat output of the appliance as specified under installation.

1.The appliance flexible connector should not be subject to undue forces, either in normal use whilst being connected or disconnected.

2.The appliance flexible connector should not be subject to excessive heat by direct exposure to flue products or by contact with hot surfaces.

3.The socket into which the plug of the appliance flexible connector fits should be permanently attached to a firmly fixed gas installation pipe and positioned such that the hose hangs freely downwards.

4.The appliance flexible connector should be positioned such that it will not suffer mechanical damage; eg abrasion from the surrounding kitchen furniture which may be moved in use, such as a door or drawer, or by being trapped by a stability device.

5.The plug-in connector should be accessible for disconnection after moving the appliance.
