Pre-Commissioning checks - 18/25 Regular shown

CAUTION: 230 Volts
▶ Isolate the mains electrical supply before starting any
work and observe all relevant safety precautions.
1. Check that the service and water pipes are connected correctly.
▶ Check that all unused sockets are capped.
2. Check that the oil supply is 28 second kerosene and that the
pipework is connected correctly to the oil pump via the supplied
flexible oil hose.
▶ Check that the burner is seated correctly on its mounting flange and
that the oil hose/s are routed correctly.
See page 43, figure 82 for correct routing of the oil hose.
▶ Turn on the main oil supply valve at the tank, check the oil supply
pipework and connections. Rectify any leaks.
3. Check the flue is correctly fitted and the connections are secure.
4. Check the condensate pipework is correctly fitted and connected.
▶ Check the condensate trap is filled with water.
NOTICE: If the boiler is not to be commissioned then:
▶ After successfully completing all of the checks and any
rectification work, close the water valves, shut off the
oil supply and electrically isolate the boiler.
▶ Complete the installation part of the Guarantee
Registration Card, and complete a CD10 or equivalent
to inform the LABC of the installation.

▶ Turn on the water main stop cock.
▶ Open vented systems only:
▶ Turn on the water to the system feed and expansion cistern and allow
the system to fill.
2. Sealed systems only:
▶ Check and if required, adjust the expansion vessel pressure using the
Schraeder type valve (C).
▶ Fill the system to between 1 and 2 bar pressure via a WRAS approved
filling link.
▶ Monitor the pressure gauge during venting and repressurise if
required.
3. Vent all radiators, retighten when completed.
If an extra expansion vessel is fitted to the central heating return, adjust
this to the same pressure as the appliance internal expansion vessel,
refer to separate instructions supplied with the extra expansion vessel.
▶ Check the system and correct any leaks.
▶ Bleed air from at least one of the secondary heat exchanger air vents
(a radiator key is ideal for this). There are two venting bosses (A) on
the top of the secondary heat exchanger. Only one can used if fluing
to the side.

Filling the system

System boiler only
The charge pressure of the built-in 10 litre expansion
vessel is 0.5 bar as supplied, which is equivalent to a
static head of 5 metres. At 1 bar pressure the vessel will
provide 92 litres expansion capacity, the boiler has a
primary water capacity of 21 to 22 litres and therefore
additional system expansion capacity may be required.
