Hearth Requirements & Clearances
Your stove must be installed on a solid, level non combustible hearth. The hearth
does not need to be constructional but must be at least 12mm thick. The hearth protrusion
in front of the stove to carpets or wooden floors must be at least 300mm. As it is possible
for fuel to fall out on opening the door, a fender must be fitted if the hearth is flush with the
carpet.
These are just a few hearth specifications. Please refer to Building Regulations Approved
Document J (Hearths) for more specific details.
Clearances to combustibles are detailed in the diagram below. 300mm above and 100mm
to the side must be obtained to any flammable material such as wooden surrounds for
example. These figures are based on the fact that the stoves forward projection is no more
than 150mm.
