3.1 Commission the Boiler

Commissioning

Open Vented Systems - Remove the pump and flush
the system thoroughly with cold water. Re-fit the pump.
Fill and vent the system then check for leaks.

Sealed Systems - Remove the pump and flush the
system thoroughly with cold water. Re-fit the pump. Fill
and vent the system until the pressure gauge registers
1.5 bar (21.5 lbf/in²) and check for leaks.

IMPORTANT: The pressure relief valve is factory tested
and does not need testing during the commissioning of
the boiler. It must not be used to reduce system
pressure as it may cause debris in the system to foul the
valve.

All Systems

Warning: Before lighting the boiler, ensure that the
outer white case has been correctly fitted and that
the sealing strip fitted to the outer white case is
forming a tight seal with the main boiler chassis.
The controls cover is left off at this stage.

Preliminary electrical system checks

These checks must be carried out before attempting to
light the boiler.

They are:-

Earth Continuity, Short Circuit, Polarity
& Resistance to Earth.

Commission

1.The whole of the gas installation must be checked

for soundness and purged in accordance with BS
6891.

2. Set the boiler temperature control knob to 'O'

Standby.

3. Turn the boiler gas service cock to the 'On' position

and ensure that the main gas supply is turned 'On'.

4. Make sure that the system is full of water and that the

pump and radiator isolating valves are open. Vent
air from the system.

5. Ensure that the main electricity supply is 'On'.

6. Check that the time control, if fitted, is in an 'On'

position and that the room and cylinder thermostat,
where fitted are set to high temperatures.

First time lighting:

7. Set the temperature control knob to its maximum

setting. The boiler will attempt to light, if the boiler
does not light within 3 attempts (due to air in the
system) the boiler controls will go to 'Lockout' and the
upper Red LED on the control panel will go to a rapid
flashing mode. To re-start the lighting sequence press
the reset button on the control panel. There will be a
short delay before the lighting sequence starts.

When the burner flame has established lower Green LED
on the user control panel will be on continuously.

8. With the main burner running, check for gas

soundness using leak detection fluid.

9. Allow the system to reach maximum working

temperature and examine for water leaks. Set the
temperature control to 'Standby' and drain the system
whilst still hot.

Note: Should the boiler fail to operate correctly refer to
the Fault Finding Guide and the boiler wiring diagram for
further information.

10. Re-fill and vent the system making a final check for

leaks.

11. On sealed systems adjust to the correct cold fill

pressure. Set the pressure gauge pointer to the
system design pressure.

12. If a by-pass circuit is fitted the by-pass valve should

be adjusted so as to maintain sufficient water flow
through the boiler to ensure that the overheat
thermostat does not operate under normal conditions.
