Multi stove fuel query

Hello all,

After some advice re my planned log burner install (which will be carried out by a Hetas fitter)

I have had three Hetas fitters round to quote me for the install, one stating that I cannot have a timber surround at all. The other two say I can.

Due to this I have been reading up myself and have been trying to clarify what I can actually install.

I have attached an image (not to scale) which shows all dimensions. The only combustible item is the timber surround which was originally in the house with an open fire.
The three walls of the chamber are all 12mm Hardie cement boards which have been dot and dabbed onto the original brick chimney chamber.

There are also 35mm slate slips surrounding the opening which bring the total depth of the chamber to 395mm.

Due to this is it possible to install a stove with a minimum distance of 300mm to combustibles at the sides? Baring in mind the stove sits within the non combustible chamber ?

Thank you In advance

The short answer is that it depends on the stove.

If you're proposing to install the Go Eco stove you've noted in the picture, then no you can't, because the minimum distance to combustibles on that is 700mm to the sides and 900mm to the front. Heat travels in straight lines so if any of the timber is in line of sight from either the sides or the front, you need to respect those distances. The installation manual also suggests that a timber shelf above the stove would be unsuitable unless you can show that it won't exceed 85 degrees
Thanks for taking the time to reply.

I was under the impression that the eco go by chatkton and Jenrick was 300mm to combustibles!? Do you have a different source of information?

My source was that I read the installation manual for it on their website. It's 300mm to the rear with twin-wall flue, 550 to the rear with single-wall flue, and in all cases 700mm to the sides and 900mm to the front

I may do. Do you definitely need multi-fuel or is wood-only OK? Surveys of homeowners suggest that around 80% of people who buy a multifuel stove only ever burn wood in it....
Height to top of mantle is 950mm from the hearth.
The bottom of the lintle where the register plate is installed is approx 940mm if that helps
