4.6.1 CONNECTIONS
Use the fittings supplied in the Hardware literature pack:
• Use the 22mm copper pipes (1 & 2) provided with the appliance, as
shown in the diagram opposite.
• If the flow and return pipes are to be run behind the appliance it
maybe an advantage to connect the pipes before hanging on the wall
especially if space is limited.

Do not use the pre-formed copper pipes supplied with
the appliance for the gas supply.
These copper pipes are for water only.
Further guidance on pipe routing can be found printed
on the appliance template (supplied with the appliance).
▶ Ensure that the pipes are adequately supported and
room between the pipes to avoid noise.
