Note: Do not trap wires between hot surfaces.
2
Measure the height of the hearth and make a mark on the wall at the same height.
3
Mark a horizontal line 425mm above the hearth level line and a vertical line on the
centre line of the fireplace (See Figure 4). At this point drill a pilot hole through the
cavity wall to the outside.
4
Cut a hole through the cavity wall to accept the flue duct. This can be achieved using
either a 127mm (5'') diameter core drill or a hole cut to the dimensions shown in Figure
4.

Provision will also need to be made to bring the power supply cable through the wall to
the fan box. This can be achieved by drilling a 25mm diameter hole (minimum) though
the wall adjacent to the hole for the flue duct. When a core drill has been used to make
the hole for the flue duct there is enough room to pass the cable through the same hole
as the flue duct but care must be taken to prevent the cable coming in to contact with
the flue duct. If this method is used it is recommended that a piece of rockwool
insulation is used to protect the power cable.
6
Once the hole for the flue duct has been made it is recommended that the fitting of the
fireplace be completed before proceeding with the installation of the fire but the gas
supply must be routed to the appliance before the fireplace is permanently fixed. The
three-core mains cable must be kept accessible.
