BTW... Free area for a pipe with a CSA of 100mm would be 78.5 cm2.

Doesn't CSA mean Cross Sectional Area ?

Did you really mean to infer that the free area for a pipe with a Cross Sectional Area of 100mm would be 78.5 cm2

Replace CSA with ID ( Internal Diameter ) and your statement becomes credible.

Accuracy is essential when dealing with the hazards of gas installations.

Yes I believe Steely did mean ID, but equally important is for DIY'ers to realise when they're not competent, despite some rather arrogant assumptions to the contrary.

When they are incompetent, some DIYers are competent.

Countering the arrogant assumptions with an explanation of the information / skill / knowledge that the DIY needs to acquire in order to become competent ( i.e. educating the DIYer about the hazards ) is more likely to deter the DIYer from attempting DIY work for which they are not competent.

Being rude and abusive in replies to a DIYer is going to drive the DIYer away without the education he or she needs to receive to be aware of the hidden hazards of DIY work.

That applies to all types of DIY work and not just gas work

I disagree. A little knowledge can be dangerous.
For every person who will be deterred, there will be one who is encouraged.
Best not to be the one who encourages - hence the rules on gas advice.

Maybe you could put the OP's mind at rest by informing him of the minimum air flow rate required for the installation in question.

From memory the ratio of air to gas should be 10:1 by volume ( 10 of air to 1 of gas ).

......that's two fooked keyboards now on this thread alone..

Whilst stoichiometric combustion has its advantages I wouldn't recommend it in this case..

I asked for the mechanical air flow rate.

But as said, a little information is a dangerous thing. You're a prime example with this alternative thinker nonsense
