Do not forget the Logbook!

Chaffoteaux & Maury supports Benchmark, the heating industry code to ensure the correct installation, commissioning and
servicing of domestic central heating systems.

To The Householder

Make sure you have a completed Logbook for your boiler.

This provides a record of the commissionning of your boiler. It

contains important information about your particular installation that may be required by service engineers. The logbook will
also provide contact details for the installer should you need guidance in the use of this appliance or if there are any problems.

As with your car, your boiler will work more reliably and efficiently if regularly serviced. We recommend an annual service
check. The service history of the appliance will be recorded on the logbook.

In the unlikely event of any problems with your boiler or system you should first contact your installer. If your installer cannot
resolve the problem he should telephone our national service helpline.

A charge may be made if Chaffoteaux & Maury Service is called out to resolve a non-product related fault.

Your statutory rights are not affected.
