Dear All,
I am looking for advice on what size gas nozzles would be required for a gas fired boiler for a friend's 3 1/2 inch single fairlie.
The plan is to follow what a gentleman in Finland has done and use a simple to make boiler that looks quite like a Lancashire type with two flues.

The cylinders are 1.5 inch bore by 2 inch stroke.
Regards,
Tom
