BENCHMARK

The Benchmark initiative is a code of practice to encourage the correct installation, commissioning and servicing of domestic cen- tral heating boilers and system equipment.

A checklist can be found in the back of every installation manual. This is a vital document that needs to be completed by the installer at the time of installation. It confirms that the boiler has been installed and commissioned according to the manufacturers instructions.

In Eire the declaration found in IS 813 must be complet- ed. Without completion of the checklist and/or declaration, manufac- turers may refuse to respond to a call-out request. It is important that the checklist and/or declaration are fully completed by your installer.
