DeLonghi DGS 61 ST User Operating Instructions Manual page 22

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.
6. 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.
The presence of bubbles will indicate a leak.
If there is a leak, tighten the fitting and then recheck for leaks.
IMPORT NT!
Do not use a naked flame to test for leaks.
