UK: INSTALLATION MANUAL AND OPERATING INSTRUCTIONS
WESTFIRE WF23 PEDESTAL/INSERT
This manual refers to the stove type listed below, which has been tested in accordance with EN 13240.
Congratulations on your purchase of a new wood burning stove from Westfire ApS. Please read this manual care-
fully in order to ensure that you get maximum enjoyment from your new stove and to prevent any problems.
Please note that "all local regulations, including those referring to national and European Standards, need to be
complied with when installing this appliance".
For further information on installing and using fireplaces and wood burning stoves, please see the relevant
brochure on building regulations that applies to the country in which WF 23 has been approved, as well as the
relevant brochure on the correct use of wood burning stoves available from your local stove supplier or your
chimney sweep.
INSTALLATION GUIDELINES
You must comply with all applicable national and local building regulations when installing your wood burning
stove. Please see the applicable regulations for full details. The regulations state that flammable floors beneath
closed hearths must be covered by a fire-proof material that extends a minimum of 30 cm in front of the stove
opening and a minimum of 15 cm on either side. The fire-proof material may be e.g. a steel plate, a glass plate,
tiles or artificial slate.
Installation of insert: The minimum distance from a flammable floor to the underside of the stove is 500 mm.
The insert must only be installed in walls constructed using non-flammable materials.
The opening in which the insert is to be installed must be at least 60 cm in height, 61 cm in width and 37,5 cm
in depth.
The floor on which the wood burning stove is to be installed must be sufficiently strong to carry the weight of the stove.
The minimum distances to flammable materials are specified on the EN 13240 plaque on the back of the stove.

There are no rules regarding the minimum distance to non-flammable walls, but we recommend leaving a gap of
at least 10 cm behind the stove to make cleaning easier.
Combustion requires air, and fresh air must therefore be available in the room in which the stove is installed. Air
inlets must be positioned in such a way that they cannot be blocked. An air inlet may be a vent (the vent must be
open and the capacity of the vent sufficient when the stove is lit) or a fresh air system linked to the stove.
All wood burning stoves from Westfire are fitted with a smoke plate which ensures that the smoke travels far enough.

CHIMNEY CONNECTION

The chimney to which the stove is connected must have a diameter of at least 15 cm, which corresponds to an
area of 175 cm2.
The chimney must be sufficiently long to provide a good chimney draft, and to ensure that the smoke from the
stove will not cause a nuisance. The chimney must be fitted with an easily accessible cleaning hatch.
WF 23 has been approved in accordance with EN 13240. The nominal heat output of this stove is 6.1 kW.
WF 23 has a test weight of 112 kg.
Minimum draft: The stove has been tested with a draft of 12 Pa. Max. draft 25 Pa.

Flue gas flow 5.2 g/sec.
Flue gas temperature 281°C.
WF 23 is fitted with both a top and rear outlet.
The chimney may be equipped with a regulation damper in the flue pipe to allow the draft to be regulated on
windy days. The damper must not be able to close fully, and must have a clearance of at least 20 cm2 of the total
clear opening of the pipe.
Other types of dampers may also be used, such as allowing air to enter the chimney by bypassing the stove.
WF 21 may be connected to chimneys to which other appliances are connected. Please note that gas-fired appli-
ances must have a separate chimney to which no other appliances may be connected.
OPERATING INSTRUCTIONS
The heat-resistant paint on the stove will harden the first time you light up the appliance. This process produces a
good deal of smoke and odour, and the room should therefore be well ventilated.
The stove door should be kept open during the first couple of firings and only closed once the stove has cooled
down to prevent the packing cord around the door from sticking and coming away from the door. Once the heat-
resistant paint has hardened, the stove door must be kept closed except when lighting the stove, adding firewood
or removing ash in order to prevent flue gas from escaping.
Before lighting the stove, open the air system by pulling the air lever out fully and opening the draft control on the
right-hand side.
Firelighters should ideally be used when lighting the stove. Never use methylated spirit, petrol or other flamma-
ble liquids to light your stove! Place a few smaller pieces of wood in the stove on top of the firelighters.
Once the fire has caught, add two pieces of wood measuring approx. 33 cm with a combined weight of approx.
1.5 kg. After approx. 4 minutes, close the draft control and close the air lever in the centre approx. 40 %. At
nominal heat output, expect to refuel your stove approx. once an hour.
For slow burning/reduced heat output simply add smaller quantities of wood less often, and close the air lever in
the centre more than 40 %.
110 cm
WF 23 is designed for intermittent combustion (wood must be added often and the stove is not designed for 24-hour use).
110 cm
WF 23 is equipped with a control valve for secondary air designed to ensure a plentiful supply of oxygen during firing.
When lit, the stove will get very hot and due care must therefore be exercised. Please use a glove when operat-
ing levers and dampers.
In the event of a chimney fire: Close the air damper and the stove door, and call 112 or your local fire department.
BASIC POSITIONS OF DAMPERS DURING OPERATION
You will need to become familiar with your stove in order to be able to regulate the secondary air intake correctly, as
factors such as the quality and height of your chimney, the quality of your fuel and the external conditions play a large
role. It is easy to see whether the stove is functioning correctly, however. Incomplete combustion may lead to a build-
up of hard, shiny soot on the inside of your stove. This is prevented by the introduction of additional secondary air.
It is important to check the draft conditions before lighting your stove. This may be done, for instance, by crum-
pling a piece of newspaper, placing it in the combustion chamber and lighting it. The draft conditions are good if
the smoke is drawn away through the chimney.
