Note: It is recommended that the gas connection to the appliance is installed with a flexible

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 abra
-
sive edges.
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.
