connections.
▶ Connect the CH return pipes to the boiler‘s 22mm compression
connections.
▶ Connect the gas supply to the boiler gas cock 22mm compression.
▶ Connect cold water in and DHW out to the boiler‘s 15mm
compression connectors.
▶ Connect the drain pipe to the heating pressure relief valve, ensuring
that the black plastic ratchet clip is then tightened securely.
▶ Connect the condensate discharge pipe work to the boiler‘s
condensate outlet connections.
