LPG noobie query

[Robert Tyrrell]

This is a query about something that - yes, I should know - but I can't remember Must be an age thing.

Anyway. I have to fit a water heater on a narrow boat, now I have my FGA back, and I can't remember if you have to gas rate the appliance, and if you do, how it's done as there's no meter?

Can anyone enlighten me please?

No just check your pressure and flame pic (make sure your nozzle size is right if they sell a ng version )
