new combi boiler installation

[Graham newby]

I am not a plumber.

22mm pipe coming from gas meter, somewhere inbetween meter and combi pipe reduced to 15mm.

Old Combi Boiler supplied by 15mm pipe.

New Boiler needs 22mm pipe.

I have 2 x 15 mm pipes available in my downstairs living room 1 is already supplying the old combi and i have a spare 15mm going to an old gas fire that was removed in the past, so there are 2 pipes in the living room. (Combi fitted in downstairs Kitchen)


Question : Can you use the 2 x 15mm pipes to supply the new 22mm pipe required for new combi.

thanks

Graham

This forum will not give non gas safe registered installers any advice regarding gas installations.

Really!
If you have to ask the question, or even consider what you are proposing. You should NOT be attempting.
Gas pipe work sizing is not just a guess!
Look after yourself and family, get a GSR to install the boiler and gas.
