7.2.4 Re-commission the burner
Fig. 66 18/25 and 25/32 Burner O-ring seal shown
▶ Remove plastic cover [1] from the burner.
▶ Fit a suitable pressure gauge to the bleed and pressure gauge port
[2] on the oil pump.
Fig. 67 Access to bleed and pressure gauge port
▶ Slide the burner into position in the heat exchanger and secure with
the retaining nut [2] on top of the burner.
▶ Reposition the flexible air supply tube [3] over the burner air supply
connection [5].
▶ Secure the flexible air supply tube [3] in place with the locking band
[4].
▶ Plug the burner lead [1] into the control box.
Fig. 68 Refitting the burner
▶ Create a heating demand, the burner should ignite following a pre-
ignition period of approximately 15 seconds.
▶ Check that the:
– Oil pressure is correct for the required appliance output.
– Smoke reading is between 0 - 1.
If the smoke reading is above 1:
▶ Check the air setting.
If the air setting is correct:
▶ Check that the burner has been reassembled correctly.
▶ Allow the appliance to warm up then:
– Ensure that the CO
2
levels are correct as indicated in table 9,
page 32.
– Adjust the CO
2
if necessary using the air shutter.
When the combustion settings are correct:
▶ Remove the pressure gauge, refit the blanking plug and plastic cover.
Before hand over
▶ Make sure oil flexible line/s are routed correctly so to avoid being
damaged or trapped.

[2] Flexible oil hose route. Ensure that the rigid 90° connection at the
pump points to right when the boiler is viewed from the front and
the flexible hose follows the route as show in the figure above.
▶ Refit the top panel [2] and press down to compress the seal when
fitting the securing screws [1].
WARNING: Flue gas leakage
The seal between the burner and the mounting flange
must form a gas tight seal to prevent leakage of
potentially dangerous gas from the combustion
chamber.
▶ Unless the burner is level when pushing the burner
into the flange the O-ring may not seat properly
allowing flue gas to escape!
▶ Always check that the O-ring seal (Fig 66 item A) is
in good condition before fitting the burner.
Replace the O-ring seal if defective.
Combustion settings
▶ Refer to table 9, page 32.
