how to gas rate an appliance using a G25 meter

[jtech24]

could anyone please tell me how to gas rate a combi boiler that is in the
residential part of the property which is above a take-away,the only problem i have is that the gas meter is a G25 which uses 40 cubic metres/hour gas and the last part of the display counter only has two digits

Unfortunately the forum has a policy of preferin not to give out diy gas advice,even basic gas advice.

If you are registered the first place to ask would have been gsr technical,there's always the combustion chamber section on the forum but don't hold your breath.

Now your scenario is one of those grey areas,if you were registered and have carried out work unless your a commercial engineer your out of scope(9/10 times).
If your doing a cp12 you've been unlucky in what you've picked.we used to be taught that if the primary meter was commercial Then anything off of it was too,do I agree.........
