Commissioning
I t is important that the oil pressure is correctly
adjusted.
After commissioning the boiler, complete the
commissioning report at the beginning of this
manual. Leave a copy for the user and keep
one.
If it is possible that the boiler is left switched
off and unused in a climatic zone with risk
of frost, the boiler and the installation must
be emptied. Alternatively, an MPG type
antifreeze (with inhibitors) must be dosed to
protect the installation at the outdoor base
temperature.
This measuring point is not suitable for
measuring the effi ciency of the boiler or the
fl ue draft.

NOTE
9.1 BEFORE SWITCHING ON
1. Ensure the boiler is isolated from the electrical supply and the
boiler On/Off switch is set to OFF.
2. Check that the high limit thermostat bulb and boiler thermostat
bulb are correctly located in their respective pockets. Refer
to Figures 5-1 and 5-2. Check condition of both thermostat
capillaries. Ensure they are not damaged, broken, kinked or
crushed.
3. Remove the nuts and washers securing the front cleaning door.
Withdraw the door – take care as it is heavy!
4. Check that the turbulators are in position and that the ends are
vertical. Refer to Figure 11-3.
5. Check that the baffl es are in position. Refer to Figures 11-1, or
11-2 as required.
6. Re-fi t cleaning door and check it is fi tted correctly and that a
good seal is made.
7. Unscrew the burner fi xing nut (located at the top of the
mounting fl ange) and remove the burner from the boiler.
8. Check/adjust the burner settings as described in Section 10.2
(Burner Settings).
9. Re-fi t the burner to the boiler and tighten the fi xing nut. DO
NOT OVERTIGHTEN!
10. Check that the sealed system has been vented and pressurised
and there are no leaks.
11. Ensure that the condensing heat exchanger has been vented
via the manual air vent (on heating return connection). Refer to
Section 5.3
12. Ensure that the air vent on the heating fl ow pipe (system
version only) is open. Refer to Section 5.3.
13. Check that all fuel line valves are open.
14. Remove the plastic burner cover if it was not previously
removed.
15. Connect a combined vent manifold and pressure gauge to the
pressure gauge connection port on the oil pump. See Figure
3-5. Open the vent screw on the vent manifold to vent the oil
supply whilst the pump is running.
16. Check that all system controls are calling for heat and turn the
boiler thermostat to maximum.
9.2 SWITCHING ON
1. Check that all system controls are calling for heat and turn the boiler
thermostat to maximum.
2. Switch on the electricity supply to the boiler.
3. Set the boiler On/Off switch to ON. A neon on the switch lights when
it is in the ON position. The boiler will now light automatically.
Note that the neon lights when the boiler is switched on, but does not
necessarily indicate the burner is fi ring.
The burner should then fi re. Open the vent screw on the vent manifold
to vent the supply while the oil pump is running
4. The burner fan should start and the burner should light within about 12
seconds. If the burner does not light and the ‘Lock-out’ reset button on
the burner lights, wait about 45 seconds and press the reset button to
restart the ignition process.
This procedure may have to be repeated several times during fi rst
lighting.
5. With the burner alight, check the fuel pressure. Refer to Section 2.3
(burner settings).
6. Adjust the pressure if necessary - refer to Section 11.8 (burner
components).
7. Operate the boiler until it reaches normal operating temperature.
Check oil supply/return pipe for leaks, rectifying where necessary.
8. Check the operation of the boiler thermostat. Ensure that by turning it
anticlockwise it switches the burner off.
9. With the burner alight, re-check the fuel pressure and re-adjust if
necessary. Turn the boiler off, remove the pressure gauge and replace
the plug in the pump.
10. Ensure that there are no oil leaks, replace the burner cover.
11. On balanced fl ue installations - Ensure the fl exible air inlet tube is
correctly connected to both the burner air inlet and the fl ue system.
NOTE
9.3 COMPLETION
1. With the system hot, check again for leaks, rectifying where
necessary. Drain the system while it is hot to complete the
fl ushing process. Refi ll and vent the sealed system.
2. A suitable central heating system inhibitor must be added to
protect the system against the effect of corrosion.
3. A suitable antifreeze should be used to prevent damage to
the boiler in areas where electrical power failure can occur in
winter months.
4. Replace the top, front and rear panels as necessary.
9.4 INFORMATION FOR THE USER
The User must be advised (and demonstrated if necessary) of the
following important points:-
• How to start and switch off the boiler and how to operate the
system controls.
• The precautions necessary to prevent damage to the central
heating system and to the building, in the event of the boiler
not being in operation during frost conditions.
• The importance of servicing the boiler to ensure safe and
effi cient operation. This should normally be required only once
a year.
• The type of fuel used.
• That any servicing or replacement of parts must only be
carried out by a suitably qualifi ed engineer.
• Ensure that the boiler controls and room thermostat (if fi tted)
are set to the User’s requirements.
• Tell the User the system pressure and show them the position of
the safety valve discharge pipe.
• Show the User how to reset the overheat thermostat and how
to restart the boiler if it goes to ‘Lockout’.
If there is any possibility of the boiler being
left during freezing conditions, then the boiler
and system should be drained. Alternatively,
a suitable heating system antifreeze should be
used.
