Flow & Return firebird C26 combi oil boiler

[Ant0912]

Hi, can anyone tell me which pipes are flow and return please.

I removed old leaking 2008 C26 firebird oil boiler in June .

We have now completed damp proofing works & I need to extend these 4 pipes to go through the wall and into a new boiler room.
This area will then be stud wall and insulated so the pipes will be encased in the wall.

Couldn’t see anything on the boiler to indicate which 22mm pipe was flow/ return .
I know which was hot and cold so those have been labelled correctly.

Just need to know so I can label them up the other side ready for my boiler installer next year.

Thanks .

Flow is on the left.

You'll want to take those isolation valves off when extending them as there will be big restrictions having your entire system going through a small ball bearing inside them

Thanks much appreciated , yes those isolation valves are only temporary.
