Direct air vent height/placement

[Big red]

Hi can anyone help please. 

I'm having a wood burner with boiler fitted soon and wanted to get the direct air vent fitted where it won't be in plane view and out of sight. 

So my question is there a specific height it must be off the ground?

Edge of the wall,middle can't find anything to help on the hetas site regarding regulations. 

It is being fitted by a hetas wet fitter .

Any information help will be appreciated

I think it is very much dependant on the specific stove, so have you chosen it yet?  If so look at the install manual

you don't have  a choice, as the spigot will be at a fixed point on the stove.

There should be instructions on the fed pipe required to outside. Whatever it says, bear in mind that air is a fluid and so the feed pipe should be as short as possible with slow bends, then outsde it should be unobstructed.

From my experience of just one such direct feed stove, it is very efficient indeed.
