SITE REQUIREMENTS

3.1 The appliance must stand on a non-combustible
constructional hearth which is at least 125mm thick with
the minimum dimensions as shown in diagram. If it is to be
fitted in a raised setting consideration may need to be given
to extending the depth of the hearth to safely containing
any falling logs or embers.
3.2 The building must have a suitable load-bearing capacity for
the hearth and appliance.
• Consult a structural engineer for advice before
proceeding
3.3 When fitting into an existing hearth check:
• That the appliance complies with current construction
regulations and is at least the minimum sizes shown
3.4 If there is no existing fireplace or chimney it is possible to
construct a suitable non-combustible housing and hearth
setting. The flue must be installed in accordance with all
local and national regulations and current rules in force.
• Check if adding a new chimney to your property requires
planning permission
3.5 Some houses are built using a timber frame construction
with high levels of thermal insulation. Isolate the appliance
from combustible materials, and provide sufficient
ventilation to maintain the heating efficiency.
