UK: INSTALLATION MANUAL AND OPERATING INSTRUCTIONS – WESTFIRE WF32
PEDESTAL/INSERT
Congratulations on your purchase of a new wood burning stove from Westfire ApS. Please read this manual
carefully 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 32 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 45 cm.
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 55 cm in height, 81 cm in width and 38 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 heat deflection baffles, which ensure the maximum efficiency
and the clean burn of the stove. These baffles should not be removed.
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 32 has been approved in accordance with EN 13240. The nominal heat output of this stove is 6 kW.
WF 32 has a test weight of 135 kg.
Minimum draft: The stove has been tested with a draft of 12 Pa. Max. draft 25 Pa.
Flue gas flow: 4.6 g/sec.
Flue gas temperature: 243°C.
WF 32 is fitted with a top 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.
More than 1 appliance on a flue system is not allowed in the UK under any circumstance.
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 left-hand side.
Firelighters should ideally be used when lighting the stove. Never use methylated spirit, petrol or other
flammable 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.
1.6 kg. After approx. five minutes, close the draft control and close the air lever in the centre approx. 70%. 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 70%.
WF 32 is designed for intermittent combustion (wood must be added often and the stove is not designed for
24-hour use).
WF 32 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
operating levers and dampers.
In the event of a chimney fire: Close the air damper and the stove door, and call 999 (112) or your local fire
department.
BASIC POSITION 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
crumpling 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.
FUEL
Never use toxic wood such as chipboard or impregnated or painted wood. Always use dry firewood. The dryness
of the firewood plays an important role since the use of wet wood results in poor fuel economy and may cause
tarry soot to form.
Newly cut wood contains 60–70% water, making it totally unsuitable for use as firewood.
Newly cut wood should be stacked and air dried under cover for two years before being used as firewood.

MAINTENANCE
Ash must be removed from the stove at regular intervals.
The stove must be completely cold before being cleaned. The outside should be cleaned using a dry cloth. The
inside of the stove should be cleaned once a year. To clean the inside, remove all ash, soot and tar residue from
the combustion chamber. The smoke plate should be removed as dirt and soot will collect behind it. The packing
cord in the door will wear over time and should therefore be checked.
The stove, the flue pipe connection and the chimney should be checked regularly by a qualified engineer. The
chimney should also be checked for blockages before relighting the stove if it has not been used for an extended
period of time.
The lacquer may wear thin in exposed places due to overheating. This, and other lacquer damage, may be
repaired using a special senotherm lacquer spray available at all stove outlets.
Ash must be stored in a non-combustible container and must not be mixed with other combustible waste.
The combustion chamber is lined with Skamol. These panels will wear over time and will therefore need
replacing. The same is true for the smoke plate.
A Skamol panel may crack if hit too hard by a piece of firewood. This has no effect on the function of the stove
(this is not the case with the smoke plate). The Skamol panels will only need to be replaced once they become
very worn and are no longer whole, or if they crack in several places.
The air damper and the stove door must be closed in the event of overheating.
OPERATING PROBLEMS
Soot forms on the window: The firewood may be too wet, or the intake of secondary air may be insufficient.
The wood burns too quickly: The chimney draft may be too strong, or there may be a leak near the door of the
stove.
The stove fails to heat fully: The firewood may be too wet.
Smoke or odour: Weak chimney draft – check for blockages in the flue pipe/chimney and check the height of the
chimney in relation to the surroundings.
Soot in the chimney: The firewood may be too wet, or the intake of secondary air may be insufficient.
