Fit the 2 thermostat pockets. Refer to Frame 9.
Note.
Frame 9 shows the relationship between the
overheat thermostat and the flow tapping.
d.
Complete the water connections by plugging the 2
front top tappings with the 2" BSP plugs provided.
Position the overheat thermostat phial into the thermostat
pocket at the opposite side to the flow pipe. The illustrations
below show the rear of the boiler with the flow and relative
overheat thermostat positions.
Ensure that the overheat thermostat phial and control sensor
are correctly secured in the pockets. Refer to Frame 13.
1.
Fit the distributor tube (supplied with the boiler) into
one of the return connections. That is one of the rear
lower ports - refer to Frame 5.
Fit the flange, using the M10 x 35mm screws and
washers provided.
Ensure that the notch in the tube flange sits correctly
into the groove on the section and that the 2 sealing
gaskets are correctly assembled on the tube.
2.
Fit the 1" tapped flange to the other lower rear
connection, using the gasket and M10 x 25mm screws
and washers provided.
3.
Temporarily screw the 2 handling bars (2" pipe) into the

4.
Complete the system connections, using suitable
jointing compound as follows:
a.
The flow connection may be made to either of the
rear top tappings (either at the same side as the
return or opposite the return).
To avoid air locks, any reduction in pipe size must
be made in the vertical plane or achieved by using
eccentric bushes.
b.
The 1" tapping in the redundant return flange may
be used for the cold feed on an open system or
connection of a pressure vessel if on a sealed
system.
If not required for this purpose it should be plugged.
