THE METER.

The Gas Connection can be made by removing the gas inlet
cover located on the left hand side of the fire box sump
assembly. Remove the 8 off fixing screw and remove the
plate plus gasket. Please note special attention should be
taken not to damage the gasket.

When a concealed gas fitting from the rear is required it is
necessary to route the pipe to the left side of the unit,
taking into account the requirements of BS 6891 1988
dealing with enclosed pipes.

When installing the firebox into a cavity wall, any part of
the installation pipe work installed in the void open to the
cavity wall must be enclosed in a gas tight sleeve. It must be sealed at the point at which the sleeved
installation pipe enters the fire (The Gas Safety (Installation and Use) Regulations Certificate of exemption
number 1 of 1996). Where the pipe enters the fire the outer sleeve must be sealed to the grommet and the
pipe must be sealed to its outer sleeve using suitable mastic.
