access for lifting the boiler from the front can be
gained for two people using the lifting points. (Fig. 24).

1. The boiler has two side water connections which are
labelled FLOW and RETURN. The front connection is the
flow pipe and the rear threaded connection is the return.
2. It is essential that the flow and return pipes are
connected to the boiler correctly. The flow connection
incorporates the boiler thermostats and a flow switch.
3. Only 22mm copper pipe can be connected (by
soldering) to the boiler flow and return. Compression
fittings cannot be used.
NOTE: On Solo 30 HE models 28mm pipe should be
used to connect to the boiler flow and return using
Flow Pipe
suitable reducing fittings.

4. If the installation requires that the system pipework
originates from the bottom of the boiler, then the flow
and return pipes will need cutting, as they terminate
upwards.

1. Connect the condensate drain using the 1"BSP nut and
seal supplied. (see section 7.6).
NOTE: To ensure the correct operation and
integrity of the condensate drainage system -
Carefully pour approximately 1 cupful (250ml) of
water into the flue products exhaust, at the top of the
heat exchanger (Fig. 25a) to ensure a seal is made in
the trap.
