Installation by authorised
technician
This manual contains instructions about how
the insert must be assembled and installed. To
ensure the function and safety of the insert,
the installation should be carried out by a Hetas
trained engineer. Contact one of our dealers who
can recommend suitable installer. When completed,
the installer should inform the local Council/
authority about the new installation.
Building application
These main instructions may give guidance which
would contravene national building regulations.
Please refer to supplementary instructions or ask
your local authority for advice regarding building
regulations.
Before installing a stove or erecting a chimney it
is necessary for you to make a building application
permission to your local authority.
The owner of the house is personally responsible
for ensuring compliance with the mandatory safety
requirements and must have the installation
approved by a qualified inspector. Your local
chimney sweep must also be informed about the
installation as this will affect the routines for
regular chimney-sweeping services.
Structural support
Check that the wood joists are strong enough to
bear the weight of the stove and chimney. The
stove and chimney can usually be placed on a
normal wooden joist in a single occupancy house if
the total weight does not exceed
400 kg.
Hearth plate
Due to the risk of falling embers, a flammable
floor must be protected by a hearth plate. It must
extend 300 mm in front of the stove and 100
mm on each side of the stove, or have a 200 mm
extension on each side of the opening. The hearth
plate can consist of natural stone, concrete, metal
plate or glass. A glass hearth plate is available as
an accessory for these models.
Final inspection of the
installation
It is extremely important that the installation
is inspected by an authorised chimney sweep
before the stove is used. Also read the ”Lighting
instructions”, before lighting for the first time.
The insert becomes very hot
During operation, certain surfaces of the
insert become very hot and can cause
burn injury if touched. Be aware of the
strong heat radiated through the hatch
glass. Placing flammable material closer
than the safe distance indicated may
cause a fire. Pyre lighting can cause quick
gas ignition with the risk of damage to
property and personal injury.
Connection to chimney
• The insert must be connected to a chimney designed to withstand flue gas
temperatures of up to 400°C.
• The stove should not be installed in a chimney serving more than one
appliance.
• The diameter of the connection sleeve is designed to fit chimney pipes
with an external diameter of Ø125 mm. A connection sleeve is available,
as an optional extra, for chimney pipes with an internal diameter of Ø150
mm.
• Normal chimney draw under nominal operation should be between 20-25
Pa close to the connector. The draft is affected both by the length and
area of the chimney, and by how well sealed it is. Minimum recommended
chimney length is 3.5 m and suitable cross section area is 120-175 cm²
(125-150 mm in diameter).
• A flue with sharp bends and horizontal routing reduces the draught in
the chimney. Maximum horizontal flue is 1 m, on the condition that the
vertical flue length is at least 5 m.
• It must be possible to sweep the full length of the flue and the soot
hatches must be easily accessible.
• Carefully check that the chimney is sealed and that there is no leakage
around soot hatches and flue connections.
Supply of combustion air
When an insert is installed, the need for an adequate supply of air to the
room increases. Air can be provided indirectly via a vent in the outer wall or
via a duct from the outside that connects to the sleeve on the underside of
the insert. The required volume of combustion air is about 20 m
3 /hour.
The connector (accessory) for the combustion air has an external diameter
of 80 mm. When duct routing further than 1 m the pipe diameter must
be increased to 100 mm and a correspondingly larger wall vent must be
selected.
In hot areas, the duct should be insulated with 30 mm mineral wool with a
moisture inhibiting outer cover. It is also important to seal around the hole
in the wall (or floor) of the lead-in using sealant.
A 1 m length of condensation insulated ducting for combustion air is
available as an accessory.
