INSTRUCTIONS

REQUIREMENTS
3.4.0
This appliance can be installed into a suitable fireplace or as a
‘
Hole in the
Wall
’
(HIW) type installation. For both types of installation the chimney or flue must
be either Class 1 (brick chimney or
7”
diameter flue) or Class 2
(5”
diameter flue) The
minimum effective height of the flue must be 3 metres,
(10’).
The flue must be clear
of obstruction and if the previous installation was intended for solid fuel it must be
swept prior to this installation proceeding.
Typical installations will use the rear exit flue for
7”
diameter unlined chimneys.
However, this appliance can be installed with a 127mm
(5”)
liner directly to the top
of the appliance. This liner (if fitted) must extend from the appliance to the flue
terminal.
3.4.1
If the base of this appliance is to be installed at a height less than 225mm then
a hearth constructed of non combustible materials must also be installed which is a
minimum of 12mm in thickness, extends a minimum of 200mm in front of the
appliance and 150mm each side of the appliance. This appliance must not be
installed directly onto carpet of other combustible floor materials. HIW installations
can legally be installed without a hearth, however we recommend some form of
physical barrier be used to ensure no close proximity can take place.
