10 Commissioning
It is important that the following
commissioning procedure is carried out
to ensure safe and efficient operation of
the boiler.
T
o access the controls, open the lower
front panel by pulling it down as shown
in Figure 10-1.
The controls are shown in Figure10-2.
10.1 Before Switching On
1. Check that the turbulators are in
position and that the ends are
vertical.
2. Check that the baffles are in position
and that the cleaning cover is
correctly fitted and a good seal
made. See Section 4.5.
3. Check that the water system has
been vented (and pressurised if
sealed system) and there are no
leaks.

NOTE
4. Ensure the automatic air vent on the
condensing heat exchanger is open.
5. Check that all fuel line valves are
open.
6. Connect a combined vent manifold
and pressure gauge to the pressure
gauge connection port on the oil
pump. See Fig. 3-4. Open the vent
screw on the vent manifold to vent
the supply while the pump is
running.
7. Set the boiler On/Off switch to Off.
C
heck that all system controls are
calling for heat and turn the boiler
thermostat to maximum.

0.2 Switching on
1. Switch on the electricity supply.
2. Set the boiler On/Off switch to On.
The burner fan should start and the
burner should light within about 12
seconds. If the burner does not light
a
nd the 'Lock-out' reset button
lights, wait for about 1 minute, then
press the reset button to restart the
ignition process. This procedure
may have to be repeated several
times during first lighting.
3. With the burner alight, check the
fuel pressure.
4. Refer to the Technical Information,
Section 2.3.
5. Adjust the pressure if necessary -
see Fig. 3-4. (Note that the 'Mains
On' neon lights lit when the boiler is
switched on does not necessarily
indicate the burner is firing. It merely
indicates that the power is
connected).
It is important that the oil pressure is
correctly set.
6. Operate the boiler until it reaches
normal operating temperature.
Check oil supply/return pipe for
leaks, rectifying where necessary.
7. Check the operation of the boiler
thermostat. Ensure that by turning it
anticlockwise it switches the burner
off.
8. 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.
9. Ensure that there are no oil leaks and
the flexible air tube is connected to
the burner (balanced flue models).
