WarninG
In order to prevent any part of the structure detaching from the wall:
It is essential that all parts of modular stone and marble fireplaces are
securely fixed to a solid wall by means of mechanical fixings.
The fireplace should never be glued to paintwork or plasterwork.
Note: We do not recommend this as a DIY installation and strongly
advise using the services of a qualified installer.
