This is maybe common knowledge but it wasn't to me.
When picking up our new van I put the gas fire on to test it, I put it on number 3 setting. The dealer told me never to do that. He said it must be put on full blast for 5 - 10 minutes to dry the condensation from the flue or else the condensation runs down the flue causing it to rust and then let's carbon monoxide enter the van.
