890 HD BF INSTALLATION INSTRUCTIONS
Please note with early cavity wall design prior to 1970. The minimum depth requirement may well be difficult
to obtain. This could result in the need for the firebox to be spaced further from the internal surface of the
plaster and to achieve this larger rebated surround maybe necessary.
Ensure that the transit bolts are removed from the top
of the firebox before installation.
Check with the supplier or manufacturer that the surround meets 150
