2.2The building must have a suitable load-bearing capacity for the hearth and appliance.

•Consult a structural engineer for advice before proceeding

2.3When fitting into an existing hearth check:

•That the appliance complies with current construction regulations and is at least the minimum sizes shown

2.4If 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

2.5Some 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.
