Firefox 5 clean burn stove

I'm just about to purchase my first stove for my narrowboat and need some advice. The stove is a Firefox 5 clean burn and I want to follow all the safety instructions as much as possible. I spoke to the manufactures of the stove and they state that it must sit on a 2 inch concrete or granite hearth but when I look at http://www.soliftec.com/boat%20stoves%201-page.pdf installation instructions, it states "THE HEARTH needs to project at least 225mm in front and 150mm to each side of the stove OR have a high lip. Made of sturdy, non-flammable material, to fully protect combustibles underneath." So nothing about the base having to be concrete or granite. The FireFox chap did say he was quoting building regulations.
My question is, are building regulations applicable on narrowboats when it comes to installing a stove and would my insurance be void if there is a fire and the stove was not sitting on a recommended 2 inch concrete or granite hearth?
Any help with this matter would be very much appreciated.

The installation of solid fuel appliances on boats is covered by the advisory British Standard BS8511:2010. This contains a lot of detail which is summarised by the Soliftec leaflet.
Building Standards are good for structures made of bricks and mortar but sometimes difficult on boats. A stove such as the Firefox 5 which has been tested to BS EN 13240 does not require such a thick hearth as the temperature does not exceed 100C. The hearth should be non-combustible board and/or tiles with a combined thickness of at least 12mm. For other stoves the hearth should be at least 125mm thick if on top of a combustible floor.
The projection of the hearth in front of the stove can be less than 225mm; the minimum is 100mm with an upstand of 50mm to stop hot ash etc falling onto combustible floor material. The upstand height can be reduced with increasing projection of the hearth.
The BSS requirement that the stove must be fixed down is often left until the end of the job; however it is often much easier to sort out a good fixing method before the flue is permanently installed.
The question as to whether an insurance policy will be void if a stove has been incorrectly installed; is beyond this advice column and is probably best answered by an insurance underwriter. We would however be very interested in the answer.
