Do not forget the Log Book!
MTS 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 Log Book for your boiler. This provides a record of the commissioning of your boiler.
It contains important information about your particular installation that may be required by service engineers. The Log Book
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 Log Book.
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 MTS Service is called out to resolve a non-product related fault.
Your statutory rights are not affected.
