Hearth Requirements & Clearances
These appliances will require a solid, level non combustible hearth (minimum 12mm
thick).
Your stove must be installed on a solid, level non-combustible hearth. The hearth
protrusion in front of the stove to carpets or wooden floors must be at least 300mm. As it is
possible, that on opening the door of the stove for fuel to fall out, 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
The stove requires the following clearances around it to ensure the heat is released into
the room and to allow sufficient combustion air flow. A combustible material clearance is
given to prevent damage to any items that may be affected by heat.
