INSTALLATION MANUAL
6.3 Building the Fireplace
Construct a studwork fireplace to the desired sizes, minimum
sizes are shown in
figure 6.1
. Any combustible material used to
construct the Fireplace must not be closer than the minimum
dimensions quoted in
table 6.1
.
The appliance should be fitted with a minimum clearance
of 100mm (
G
in
figure 6.2
) from any combustible objects or
materials; this includes any combustible materials used for the
fireplace construction. This clearance distance can be reduced to
50mm if a cement Board, e.g. promatec, of minimum thickness
12mm is used. This cement board will act as a thermal break.
The clearance distance of the flue from combustibles must not
be less than 75mm (
I
in
figure 6.3
).
Cement board can be used directly against the Frame Face on
the appliance.
Do not use insulation material (or other) to pack the void around
or above the appliance.
6.4 Flue Connection
6.4.1 General notes
This appliance may be installed with a roof termination with a
rigid or flexible pipes, or in a masonary chimney class 1 or class 2
and without lining the flue. The flue system must be constructed
from the appliance upwards, with all joints being fully locked
and sealed.
6.4.2 Timber Frame Construction
Whilst it is possible to install room-sealed appliances in timber
frame properties, great care needs to be taken to ensure that
the flue assembly does not interfere with the weatherproofing
qualities of any outer wall which it may penetrate. Before
attempting this work, it is advisable to consult with a qualified
installer.
6.4.3 Carport or Building Extension
Note:
A covered passageway should not be treated as a carport.
Flues should not be sitedin a covered passageway between
properties.
