3.7.1 CONNECTIONS
Heating System 22mm compression fittings
Gas 22mm compression fittings
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.
Further guidance on pipe routing can be
found printed on the boiler template
(supplied with the boiler).
