This doesn't answer your question but...
A few years back I lived on a boat which had an old oil fired stove (constructed from stainless steel) for heating. It didn't have any instructions and when I first used it I turned up the drip-feed control too quickly 'cos I was cold; this resulted in the oil pooling in the bottom of the stove which was still cold.
After 1/2 an hour it warmed up to the point where the oil started burning off and the stove suddenly got very hot indeed - the flue pipe above the stove was glowing bright red; the inner wall of the stove (visible through the vent holes in the outer wall) was glowing orange!
I put the dog out on the pontoon and had the phone on deck with nines already punched in whilst I rushed up and down sponging down the (wooden) bulkhead to which the stove was bolted and the (wood & fibreglass) deck around the flue pipe fitting. After about five mins of near panic it burned off the surplus oil and settled down to a normal temp.
The relief was blowing from my ears like steam.
Still; got the boat to a balmy 23°C
If you know what stove you're going to fit you could ask the manufacturer about their recommendations about fitting in 'flammable' buildings - people often install them in wooden sheds, houseboats and those finnish wooden chalet-type self-build houses.
