z

Slowly fill the boiler with water through the drain cock. 
At the same time vent the system at the boiler flow 
connection.

z

If a hub connection is leaking, first drain the water 
through the drain cock.

z

Remove the return header.

z

Remove the nuts from the four tie bars and then the 
bars themselves.

z

Separate the boiler sections by driving (hammering) 
flat wedges or chisel at the points provided (Fig. 22, 

Item 1 & 2

) at the top and bottom between the 

relevant sections.

You must use new nipples and gaskets for the re-
assembly. Draw the boiler sections together and re-test 
for leaks.

2.5.2

Test pressure

The test pressure during the leak test depends on the 
design pressure for each individual heating system and 
should be 1.5 times nominal pressure (normally 7.8 bar 
for 30 minutes).
Use a pressure gauge class 1.0 for measuring the 
pressure.

z

The weld neck flange is fitted to the upper boiler hub 
(Fig. 23, 

Item 6

 – return connection) when the return 

is installed later. 

 

The illustration shows the weld neck flange and the 
flat gasket (Fig. 23, 

Item 4 & 5

).

z

The flow connection flange (Fig. 23, 

Item 3

) and the 

flat gasket (Fig. 23, 

Item 2

) are required for the flow 

connections which is fitted later (Fig. 23, 

Item 1

).
