Its 25mm below gutters if these are painted or plastic and you are within a metre of them then you use a heat shield a metre wide to protect them, As for the door that only comes into it if there is a car port..

TBH Doyle, I would speak to Ravenheat.

The diagram needs clarification. What do they mean "From a terminal guard" in items B - F?

It would appear they have no minimum dimension horizontally to an opening (door, window, vent grille, etc.) other than under a car port.

So what about the internal or external corner? hardly going to put a heat shield on those!

Half the standards are garbage these days - manufacturers too lazy to think it through.

Such as a condensing boiler flue close to a plastic gutter - have to install a heatshield to comply despite the fact that many heat exchangers are made of plastic and many flues are also plastic

Giblets ,,The question possed was about gutters this has been answered.

Gasguru a lot of manufacturers are doing away with the need for heat shields which as you imply are pointless when flues etc are made of platic

ravenheats says its refering to "heat sheild" the specifics of 25 mm are not to guttering as per instructions as it relates to heat sheild which they call a terminal guard. so its 25 mm min to heat sheild. very misleading as its all standards in measurements ie 1 mtr from gutter but they put 25mm from t/g ect so doors and windows are as bs's and not no min required.
