6.10 USER INFORMATION
The User must be advised (and demonstrated if necessary) of the following important points:-
1. How to light and turn off the boiler and how to operate the system controls.
2. The importance of annual servicing of the boiler to ensure safe and efficient operation and maintain the boiler
guarantee.
3. That any servicing or replacement of parts must only be carried out by a Gas Safe registered engineer.
4. Ensure that the boiler controls and room thermostat (if fitted) are set to the User's requirements.
5. Tell the User about the sealed system pressure.
6. Tell the User that if the electrical supply is on and the boiler has not operated for 24 hours for heating or hot water, the
pump will automatically operate for 30 seconds.
7. Explain to the User that an internal frost thermostat is fitted in the boiler, and that the electrical supply to the boiler must
be left on for the thermostat to operate, i.e. the boiler must be set to standby.
8. Explain to the User that in certain weather conditions the flue terminal will emit a plume of steam, i.e. water vapour. This
is safe and quite normal.
9. Show the User the position of the condensate discharge pipes.
10. Leave the instructions with the User.
11. Ensure the Benchmark Checklist at the back of these instructions has been completed after the boiler has been
installed and commissioned.
Note: It is a requirement that the installation is registered by the installer through the Gas Safe Gas Work Notification Scheme.
12. Leave these Installation and Servicing instructions with the User for use on future calls.
