Installation and Operating Instructions for Inspire 40/45 Pevex1020/AH/ver1.1:Jan 2014
Congratulations on your new stove.
We are sure that you will be happy
with your investment, especially if you
follow the advice and instructions we
have put together in these operating
instructions.
The Inspire 40/45 have been appro-
ved according to the EN 13240, NS
3058/3059 and AEA.
Approval means that consumers can
be sure, that the stove meets a range
Combustible materials should
not be stored in the compartment
below the ashpan.
IMPORTANT
1. Make sure there is adequate provi-
sion to sweep the chimney.
2. Make sure there is adequate venti-
lation to the room.
3. Please note that any extraction fans
operating in the same room as the
woodburning stove can reduce the
chimney draft – which may have an
adverse eect on stove combustion
properties. In addition, this may
cause smoke to be emitted from the
stove
when the ring door is opened.
4. It must not be possible to cover any
air vents.
The floor
It is essential to ensure that the oor
surface can actually bear the weight
of the stove and a top-mounted steel
chimney, if applicable. The stove must
stand on a nonammable surface as
a brick or tile oor. The size of the nonam-
mable surface used to cover the oor
of specications and requirements
intended to ensure that the materi-
als used are of good quality, that the
stove does not adversely aect the
environment, and hat it is economical
to use.
With your new stove you should have
received the following:
a. Operating instructions
b. A stove glove
Safety clearances
Stoves must always be installed in line
with national and, if applicable, local
regulations. It is important to abide by
local regulations regarding setting up
chimneys and connection to same.
Therefore, always consult your local
chimney sweep before installation, as
you are personally responsible for en-
suring that the applicable regulations
have been met.
Distance regulations
A dierence applies to installation
next to ammable and non-ammable
walls.
If the wall is made of non-ammable
material the stove can, in principle, be
placed ush against it. However, we
recommend leaving a gap of at least
5 cm to facilitate cleaning behind the
stove. The minimum distances to
ammable material are stated on
the boiler plate and are listed in the
table on page 8.
Warning
A stove gets hot. (In excess
of 90 degrees) Take care to
en sure that children cannot
come into contact with it.

area must match national and local
regulations.
The chimney connection
The chimney opening must follow
national and local regulations. Howe-
ver, the area of the opening should
never be less than 175 cm2, which
corresponds to a diameter of 150 mm.
If a damper is tted in the ue gas
pipe, there must always be at least
20 cm2of free passage, even when
the damper is in its “closed” position.
Wood-burning stoves must never
be connected to chimneys that are
also linked to a gasred heater. An
ecient stove makes high demand on
chimney properties – so always have
your local chimney sweep evaluate
your chimney.
Connection to a brick chimney
Brick a thimble into the chimney and
seat the ue gas pipe in this. The
thimble and ue gas pipe must not
penetrate the chimney opening itself,
but must be ush with the inside of
the chimney duct. Joins between
brickwork, the thimble and ue gas
pipe must be sealed with reproof
material and/or beading
Connection to a steel chimney
When tting a connection from a top-
output stove directly to a steel chim-
ney, we recommend tting the chim-
ney tube inside the ue gas spigot so
that any soot and condensation drops
into the stove itself rather than col-
lecting on the exterior surface of the
stove. Changing smoke outlet from
top-mounted to rear-mounted (see g.
8-15 on page 11).
For connections to chimneys that are
run through ceilings, all national and
local regulations regarding distance to
ammable material must be followed.
It is important that the chimney is
tted with roof support so that the top
panel of the stove is not required to
bear the entire weight of the chimney
(excessive weight may damage the
stove).
Draft conditions
Poor draft may result in smoke being
emitted from the stove when the door
is opened. The minimum chimney
draft to ensure satisfactory combu-
stion in stoves of this kind is 13 PA.
However, there will still be a risk of
smoke emission if the ring door is
opened during powerful ring.
Inspire 40 / 45: The ue gas tempera-
ture at nominal output is respectively
263°C and 221°C when expelled to an
exterior temperature of 20°C. The ue
gas mass ow is respectively 3.7 g/
sec and 4.0 g/sec.
The chimney draft is generated by the
dierence between the high tempera-
ture of the chimney and the low tem-
perature of the fresh air. The length
and insulation of the chimney, wind
and weather conditions also have an
eect on the ability of the chimney to
generate appropriate under pressure.
If the stove has not been used in a
while, check that the chimney and
stove are not blocked with soot, bird
nests, etc., before using it.
Reduced draft can occur:
• The dierence in temperature
is too small – due to insucient
chimney insulation, for example.
• The outdoor temperature is too
high – in summer, for example.
• No wind is blowing.
• The chimney is too low and shel-

INSTRUCTIONS FOR USE
First firing
The stove has been treated with a
heat-resistant coating which hardens
at a temperature of approximately 250
ºC. This hardening process causes the
production of smoke and malodorous
fumes, so the room must be very well
ventilated. During the rst ring, which
should be carried out using approxi-
matly 1 kg of wood, the stoking door
must be opened slightly every 10 mi-
nutes for the rst two hours to prevent
the sealing rope sticking to the stove.
Fuel
Your new stove is EN approved for
ring with wood fuel. You must there-
fore only burn clean, dry wood in your
stove. Never use your stove to burn
driftwood, as this
may contain a lot of salt which can da-
mage both the stove and the chimney.
Similarly, you must not re your stove
with refuse, painted wood, pressure-
impregnated wood or chipboard, as
these materials can emit poisonous
fumes and smoke. Correct ring
using well seasoned wood provides
optimal heat output and maximum
economy. At the same time, correct
ring prevents environmental damage
in the form of smoke and emmissions
and also reduces the risk of chimney
res. If the wood is wet and inade-
quately seasoned, a large proportion
of the energy in the fuel will be used
to vaporise the water, and this will
all disappear up the chimney. Thus it
is important to use dry, well seaso-
ned wood, i.e. wood with a moisture
content of no more than 20%. This is
achieved by storing the wood for 1–2
years before use. Pieces of rewood
with a diameter of more than 10 cm
should be split before storing. The
pieces of rewood should be of an
appropriate length (approx. 18 cm) so
that they can lie at on the bed of em-
bers. If you store your wood outdoors,
it is best to cover it.
Examples of recommended
woods types
and their typical specic gravity per
cubic meter stated as 100% wood
with a moisture content of 18%
tered.
• The chimney contains false air.
• The chimney and ue gas pipe are
blocked.
• The house is too airtight (i.e. when
there is an insucient supply of
fresh air).
• Poor smoke extraction (poor draft
conditions) due to a cold chimney
or bad weather conditions can be
compensated for by increasing
the airow into the stove.
Good draft occurs when:
• The dierence in temperature
between the chimney and outdoor
air is high.
• The weather is ne.
• The wind is blowing strongly.
• The chimney is of the correct
height: at least 4.00 m above the
stove and free of the roof ridge.

It is advised not to use very oil-
containing woods like teak tree
and mahogany, as this can cause
damage to the glass.
Heating value in wood
You have to use about 2.4 kg normal
wood to replace one litre of heating
oil. All woods have almost the same
heating value per kg, which is about
5.27 kW/hour for absolute dry wood.
Wood with a moistness of 18% has a
eciency of about 4.18 kW/hour per
kg, and one litre heating oil contains
about 10 kW/hour.
CO2release
At combustion 1000 litres of heating oil
forms 3.171 tons CO2. As wood is a
CO2neutral heat/ energy source, you
save the environment about 1.3 kg
CO2every time you have used 1 kg
normal wood.
Chimney fires
In the event of a chimney re – which
often results from incorrect operation
or protracted ring with moist wood
– close the door and shut o the se-
condary air supply to smother the re.
Call the re department.
Airflow regulation
To adjust combustion airow, use the
handle at the front under the door.
Combustion air ow is fully open when
the handle is as far as possible to the
right. To close gradually, slide the
handle to the left (g. 1).
The Inspire 40/45 stoves are designed
and tested to burn extremely cleanly
with very little smoke discharge and
are exempt for use in smoke control
areas throughout the UK when burning
dry wood logs. To comply, a perma-
nent stop is tted to ensure that the air
control slider cannot be closed bey-
ond 41% of its fully open position. A
permanent amount of air will therefore
enter the rebox to feed the re produ-
cing negligible amounts of smoke and
unburnt hydrocarbons. The appliances
will only be considered as an exempt
appliances if this stop is in place.
Lighting
To ignite the fuel, use re lighters,
small paran ignition bags or small
pieces of wood placed on the bottom
grate. Place larger pieces of wood on
top of this kindling material, at right
angles to the ring, doors. Complet-
ely open the secondary air supply and
leave the ring door ajar – i.e. approx.
1 cm open. Once the re has taken a
good hold of the fuel and the chimney
has heated up (after about 10 min)
close the ring door. We recommend
that you burn the entire rst ring
with the secondary air supply fully
open to make sure that the chimney is
thoroughly heated.

3. With plenty of air the ames will burn
brightly quickly warming the stove and
chimney.
4. After about 5/10 minutes and with the
re established the door can be shut
and the stove can be controlled by the
airslider. Adjust the airslider to control
the burning rate and to give optimum
combustion.
5. After about 40/50 minutes and when
the last ames go out a red hot ember
bed will be left and further wood can be
added.
6. Place 2/3 logs on the ash bed ensu-
ring that the wood is not stacked too
closely and with the adjust the side
airslider to fully on position. The wood
will light in 2/3 minutes. Adjust the air
slider for optimum combustion.
Lighting instructions for Heta stoves
1. Place some scrunched up newspaper
and relighters on the base of the stove
and stack some small pieces of wood/
kindling on top into about 3 layers lea-
ving gaps in between.
2. Fully open the air control. Light the
relighters and leave the door slightly
ajar to allow air to enter and the re to
establish.

Installation and Operating Instructions for Inspire 40/45 Pevex1020/AH/ver1.1:Jan 2014
Once the ames have taken hold, the
air supply can be regulated to give the
required amount of heat.
Note:
If the re dies down completely or
embers are smoldering then it will be
necessary to place some screwed up
paper or relighters onto the grate
with some kindling or small pieces
of wood to reestablish the re once
again. Leave the airslider fully open
and allow the re to build before
refueling with larger pieces of wood
and then adjust the slider for optimum
combustion.
Do not overload the rebox by
loading above the tertiary air dif-
fuser at the back of the rebox and
ensure that the wood is retained by
the log guard. Always ensure that
the wood is not tightly stacked so
that air can circulate freely.
Do not leave the door open: Opera-
tion with the door open can cause
excess smoke. The appliance must
not be operated with the appliance
door left open except as directed in
the instructions.
Do not leave the airsliders complet-
ely open: Operation with the airsli-
ders permanently open can cause
excess smoke. The appliance must
not be operated with air controls or
dampers left open except as di-
rected in the instructions.
Refuelling
You should normally rere the stove
while there is still a good layer of
embers. Distribute the embers across
the bottom grate, place pieces of fuel
(max 1 kg) on the embers in a single
layer perpendicular to the ring ope-
ning. Close the ring door and fully
open the secondary air supply. The
wood will then ignite very quickly – i.e.
in 30 seconds or 1 minute. When the
wood is burning with a steady ame,
adjust the secondary airow to the le-
vel required. For nominal operation (4
kW), the secondary air supply should
be 65% open. When ring, take care
not to place the pieces of fuel too clo-
sely together, as this will result in poor
combustion and insucient exploita-
tion of the fuel.
Reduced burning
The stove is well suited to intermit-
tent use. If you wish to operate the
stove with reduced output, simply
insert smaller volumes of wood at
each ring, and apply a lower airow.
However, remember that the second-
ary combustion air supply must never
be shut o completely during ring.
It is important to keep a good bed of
embers. Gentle heat is released when
the re settles - i.e. when the wood no
longer generates ames and has been
converted to glowing embers.

Optimal firing
To achieve optimal ring and the
highest possible eect, it is important
to make sure that the air supply is
used correctly. As a general rule, the
secondary air is to be used to control
the re to ignite the ue gases. This
produces a high eect and keeps the
glass panel completely clear of soot
as the secondary air “washes” down
over it. Please note that the stove will,
naturally, produce soot if the second-
ary air intake is closed completely.
This will prevent oxygen from being
drawn into the stove, and the viewing
window and other parts will become
covered with soot. If this situation is
combined with ring with wet wood,
the build-up of soot can become so
thick and sticky that the sealing rope
can, for example, become detached
when the door is opened the next day.
Risk of explosion
After you add new fuel, it is
very important that you do
not leave the stove una-
ttended until the wood is burning
constantly. This will normally occur
within 30 to 60 seconds.
A risk of explosion can possibly arise
if too much wood is placed in the st-
ove. This may result in the production
of large volumes of gas, and this gas
can explode if the intake of secondary
air is insucient.
It is an advantage always to leave
some ash lying in the bottom of the
combstion chamber.
Take care when emptying the ash
pan, as cinders can continue to
burn in the ash for long periods of
time.

OPERATIONAL PROBLEMS
The chimney must be swept at least
once a year, we recommend the use
of a NACS (national association of
chimney sweeps) registered chim-
ney sweep. In the event of smoke or
malodorous fumes being produced,
you must rst check to see whether
the chimney is blocked. The chim-
ney must, of course, always provide
the minimum draught necessary to
ensure that it is possible to regulate
the re. Please note, however, that
chimney draft is dependent on the
weather conditions. In high winds, the
draft can become so powerful that it
may be necessary to t a damper in
the ue gas pipe to regulate the draft.
When cleaning the chimney, soot and
other deposits may come to fall on the
smoke turning plate. In cases where
the wood burns too quickly, this may
be due to excessive chimney draught.
You should also check to make sure
that the door seal is intact and cor-
rectly tting.
If the stove it generating too little heat,
this may be because you are ring
with wet wood. In this case, much of
the heating energy is used to dry the
wood, resulting in poor heating eco-
nomics and an increased risk of soot
deposits in the chimney.
Check whether the air holes in the
stones are blocked with for example
ashes etc.
VENTILATION
Adequate ventilation must be provided
in accordance with building regulati-
ons (Doc J Oct 2010) especially when
installing in newer build properties
when the stove is not going to be
installed to an outside air supply.
The Inspire 40/45 has a nominal
output of less than 5kW and does not
need additional ventilation in older
properties where it will be ventilated
by natural leakage.
Houses built after 2008 where the air
leakage rate is less than than 5m3/
hour/m2 then a ventilator equivalent
to 550mm2 per kW output will be re-
quired (4.5kW x 550mm = 2475mm2)
unless the stove is connected to an
outside fresh air supply.
