when fitting central heating does the boiler have to go direct to meter or can i connect boiler to gas pipe in kitchen which runs cooker, because the boiler is being placed in the kitchen but the meter is in the front room which is about 30 feet and 6 corners away.

no the boiler does NOY have to connect at the meter. the meter is the first place you gas comes through so anywhere after that is fine
Typically it is best to connect boiler gas line direct to the source, but not necessary. You will notice a draw from your kitchen cooker when the boiler unit kicks on if T’d off the kitchen cooker, but will work fine.
Be sure to pressure test the new installed line prior to connecting to cooker line, and make sure gas is off and bled from line before making connections, then soap test new connection after pressurizing line with gas – or have a professional install it for you.
this work should be done by a corgi reg fitter ..i would never connect a boiler after the cooker supply ..allways before
Most modern boilers,especially combis burn at a higher rate so the correct volume has to be spot on.With or without other gas appliances the supply should be upgraded.The distance from the meter to the boiler will also contribute to the diameter of the supply.Your corgi registered installer should know this.
Any stipulation for the gas supply to the boiler in boiler instructions is a minimum requirement not necessarily the correct size. Pipe-sizing for gas appliances is one of the things that you are assessed on when tested for competence.
With the trend for ever larger combis such as 37kw nett = to roughly 41KW gross plus range cookers you have to look at maximum demand down each length of pipe and using tables work out pipe sizes so you only get 1mb drop between meters and each appliance with everything running on maximum.
With pre-mix condensing boilers there is an extra risk that if you get it wrong, when the boiler fires up it can suck the flame out of a hob say, as these suck gas down the pipe-work and will act on whichever pipe has the least restriction. I could explain this further but would take too long.
I have seen this happen and it is quite dramatic. This is immediately dangerous and resulted in me capping off the boiler from the gas.
well if the boiler has a demand for a 22mm copper pipe gas run make sure that the pipe has not been increased FROM 15mm. If theres a 22mm run from your gas cooker or it reduces to 15mm just before use a tee junction on the 22mm and run the22mm pipe from there.If you need to reduce it down after then do so. always run in a bigger pipe and then reduce it down if you need to. when running the gas pipe use a bending machine to bend the pipe around the inside corners where possible and convient because elbows retrict the flow of gas, use elbows sparingly and effectively (for the outside of corners). Make sure you pipes are well clipped. in any case you call a corgi registered plumber to deal with those things lol. hope this has been helpful
