5.3 Hanging the appliance
Before hanging the appliance
1. Remove the orange plastic protective cover strip fitted to the
appliance internal pipes by tilting the appliance forward, taking care
to protect the floor from residual water. It is not necessary to lay the
appliance on its back.
2. After soldering/connecting pipes, ensure that the appliance internal
plastic PRV pipe [1] is then connected to the Pre-plumbing manifold
(the printing on the pipe must be facing towards you).
3. Ensure that 3 black plastic ratchet clips are securely fixed and
tightened. Ratchet clip number 4 must be fitted but left loose until the
boiler is hung and connection to the PRV is made (


▶ Ensure that the condensate drain is 22mm diameter plastic pipe. It
must fall at least 52mm per metre towards the outlet.
▶ Refer to Fig. 46, condensate connection:
▶ Align the installation side plastic pipe work through the pre-plumbing
