Installation instructions

Leak-testing and flame-testing the cooktop

Important!

13

The operation of the cooktop, including the ignition system, must be tested before installation is complete. If, after following the instructions below, satisfactory performance cannot be obtained, contact the local gas authority or your local Authorised Service Centre for advice and assistance.

Checking the connections for leaks

After installation and making all connections, check thoroughly for possible leaks and make sure all connections are gas-tight.

1Turn all control dials to O (OFF).

2 Open the valve on the gas supply.

3 Check each connection one at a time by brushing a soap and water solution or a suitable leak detection fluid over it.

Important!

Do not use any naked flames to check for leaks.

The presence of bubbles indicates a leak. Tighten or replace connections as appropriate, then leak-test all connections again. For CG604DWFC and CG905DWFC models, ensure a fibre washer (supplied) is located between the elbow and the cooktop’s gas inlet and---if the conical adaptor is installed---between the adaptor and the elbow.

Checking the burner flames

1Light each burner.

2Check for a well-defined blue flame without any yellow tipping. See Fig.4.

If any abnormality is evident, check that:

-the burner cap is located properly

-the injector nipple is correctly aligned

-the correct size injectors are installed.
