CDA are not legally able to provide any assistance in the installation of gas appliances
except to Corgi registered installers. Any Corgi registered fitter requiring help must pro-
vide name, address and registration number.
Information supplied will be validated before help is provided.
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.
IMPORTANT! Do not use a naked flame to test for leaks.
Warning: Only a C.O.R.G.I. registered installer, also with technical knowledge of electricity
should install the appliance. He should observe the Regulations and Codes of Practice
governing such installation of gas appliances.
Note: It is recommended that the gas connection to the appliance is installed with a flexible
connecting tube made to BS5386.
Notes:
Flexible hoses can be used where the sited ambient temperature of the hose does not exceed
70°C.
These hoses must be manufactured in accordance with BS669 part 1 and be of the correct
construction for the type of gas being used.
Gas hoses designed for natural gas MUST NOT be used for supplying LPG gas (LPG gas
hoses can be identified by a either a red band or stripe on the rubber outer coating of the
hose).
The hose should not be crushed or trapped or be in contact with sharp or abrasive edges.
