Oil Tanks with a capacity of less than 3,500 litres should not be placed within 1.8 metres of a flu outlet.
Where these clearances cannot be achieved, the protection measures noted in British Standard BS 5410: Part 1: 1997 must be provided by means of a 30 minutes fire-resistant wall which extends at least 300mm above and beyond the ends of the tank.
For oil tanks with a capacity over 3,500 litres or advice on constructing a fire resistant barrier, please contact OFTEC.
