14.8 Re-commission the Burner.
1.
Connect the flexible oil supply hoses to the connection block
as described in Section 11.5. The flexible oil line on the inlet to
the oil pump goes to the inlet on the connection block and the
flexible oil line on the return of the oil pump goes to the return
on the connection block.
2.
With the sponge O-shaped gasket around the burner blast
tube insert the burner into the burner mounting flange ensuring
that the cut out in the gasket lines up with the burner retaining
screw. Push the burner firmly forward to compress the gasket
and tighten the burner retaining screw located to the left of the
control box using a 4mm hexagon driver.
Note:
It is important that a good seal is made between the burn-
er and the boiler to prevent re-circulation of the combustion
gases from the combustion chamber to the burner inlet.
3.
Reconnect the electrical lead plug into the external control box.
4.
Turn on the oil supply at both the oil tank and between the
burner and oil filter.
5.
Re-commission the burner as described in Section 12.
NOTE:
After commissioning/sevicing the appliance the engineer
should position the service switch in the
RUN
mode as shown in
fig. 29.
