assumed to work

The installer is responsible under the health and safety at work act 1974 vi the caustic nature 

of fire cement and the possibility of disturbing asbestos and other materials such as ceramic in 

existing installations and to suggest appropriate protection to be given to the person (s) carrying 

out the installation. The complete installation must be carried out with due reference to the British 

Standards,  Codes of Practice and Building Regulations relevant to the fuel type being installed, 

and the manufacturers installation instructions.

This document is a General Installation Guide only. It does not replace the installation instructions 

or building regulations. No installation should be undertaken unless the installer is suitably 

qualified.
