switch.
3. The boiler connections will accept 22mm fittings.
NOTE: On 30 models 28mm pipe should be used to connect to the boiler flow and return using 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.
