Safety instructions explained

This symbol warns against the risk of injury.
Note
Details identified by the word "Note" contain additional information.

Target group
These instructions are exclusively intended for qualified contractors.

• Work on gas installations must only be carried out by a registered gas fitter.
• Work on electrical equipment must only be carried out by a qualified electrician.

Working on the system

• Isolate the system from the power supply (e.g. by removing the separate fuse or by means of a mains isolator) and check that it is no longer 'live'.
• Safeguard the system against reconnection.
• Where gas is used as the fuel, close the main gas shut-off valve and safeguard it against unintentional reopening.
