Alpha Pro Tec Plus 50, 70, 90, 115 - Commissioning

5.6 FINAL COMMISSIONING

1. Allow the heating system to heat up, then balance the system to achieve the necessary temperature difference across

the heating flow and return pipes at the boiler and check the system volume and pressure. (Refer to Technical Data,

Section 2.1).

2.  Turn off the boiler.
4.  Thoroughly flush out the water pipework (refer to Section 3.10).
5.  Re-pressurise the system as described in Section 5.1.

5.7 CHIMNEY SWEEP FUNCTION - COMBUSTION CHECKING

This function allows the combustion and gas rate checks to be conducted

according to the data tables in Section 2.3. In the engineering function the

boiler output can be adjusted between 0% and 100% of the output range

(Minimum to Maximum output).
To activate this function press and hold in button 'A'.

First select minimum output (0%) by pressing the DHW - button and check

the CO

value according to the table in Section 2.3. Then select maximum

output (100%) by pressing the DHW + button, again checking the CO

value

and gas supply working pressure as specified in the table in Section 2.3.
Output values between 0% and 100% can be selected using the CH + and -

buttons to change the value in 1% increments. This function can be used to

hold the boiler at a desired output level and conduct system tests and checks.
During this function all external controls and thermostats are inactive and only the overheat thermostats and safety controls

remain active. This function can be disabled by pressing and holding in button 'A'.
If you enable this function when no external demand is present, please wait 1 minute to allow the burner to reach the desired

output and stabilise. If you enable the function during an external request, i.e. the boiler is working in heating mode, you will

need to wait at least 3 minutes for any overrun and purge cycle to finish before the burner reaches the selected output and

any measurements can be taken.

5.8 FINAL ASSEMBLY

1.  Raise and secure the control panel, replace the front cover and secure in position with the screws previously removed.
2.  If the boiler is to be left in service with the User, set any external controls to the User's requirements.
3.  If the boiler is not to be handed over immediately, close the boiler gas service cock and switch off the electrical supply.
4.  If there is any possibility of the boiler being left during frost conditions, then the boiler and system should be drained. It is

recommended that a label is attached to the boiler drawing attention to the fact that the system has been drained.

5. Complete the details of the installation in the Benchmark Checklist at the back of this manual.

5.9 USER INFORMATION

The User must be advised (and demonstrate if necessary) of the following important points:-
1.  How to light and turn off the boiler and how to operate any external system controls.
2.  The importance of annual servicing of the boiler to ensure safe and efficient operation.
3.  That any servicing or replacement of parts must only be carried out by Gas Safe registered personnel.
4.  Ensure that the boiler controls 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, the pump will automatically

operate for 5 minutes.

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.

8. Explain to the User that in certain weather conditions the 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 pressure relief valve and condensate discharge pipes.
10.  Hand the User's instructions to the User.
11.  Ensure the Benchmark Checklist at the back of this manual 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.
