4.13. SUMMARY DIAGRAM FOR IDEAL CONNECTION
OF THE INSERTS
The installation described below is ideal for inserts assembled on old or
new fireplaces; the insert must never be walled up but kept 5mm
detached from any masonry surface since it needs to be able to expand
when it is hot; furthermore, if it is walled up there is a significant drop
(30÷40%) in the thermal efficiency because the heat is not allowed out
completely but only in part.
Insulate the structure thoroughly only if there are
parts in wood or flammable material nearby.
