PRECAUTIONS.

 Check that the service and water pipes are
connected correctly.
 Check that all unused sockets are capped. 
2
 Check that the oil supply is kerosene and
that the pipework is connected correctly
to the oil pump via the supplied flexible oil

 Turn on the main oil supply valve at the
tank, check the oil supply pipework and 
connections. Rectify any leaks.

 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

NOTE: The cabinet is not load bearing, it only

IMPORTANT: If the boiler is not to be 
commissioned immediately 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 its equivalent, to inform the LABC
of the installation.
