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 40/45/55/55H have been
approved according to the EN 13240,
NS 3058/3059 and and recommended as exempt for use within smoke
control areas throughout the UK (see
clean air act Appendix A).
Warning
A stove gets hot. (In excess
of 90 degrees) Take care to
ensure that children cannot
come into contact with it.
Combustible materials should
not be stored in the compartment
below the ashpan.
IMPORTANT
1. Make sure there is adequate provision to sweep the chimney.
2. Make sure there is adequate ventilation to the room.
3. Please note that any exhaust fans
operating in the same room as the
woodburning stove can reduce the
chimney draft – which may have an
adverse effect on stove combustion
properties. In addition, this may
cause smoke to be emitted from the
stove
when the firing door is opened.
4. It must not be possible to cover any
air vents.
Approval means that consumers can
be sure, that the stove meets a range
of specifications and requirements
intended to ensure that the materials used are of good quality, that the
stove does not adversely affect 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 ensuring that the applicable regulations
have been met.
Distance regulations
A difference applies to installation
next to flammable and non-flammable
walls.
If the wall is made of non-flammable
material we recommend there be 100
mm of space to top and the sides also
50 mm to the back, this allows for sufficient convection air.
The minimum distances to flammable material are stated on the stove
plate and are listed in the table on
page 9.
INSTALLATION INSTRUCTIONS

Operating Instructions dated July 2015 reference ”Pevex1020/AH/ver2.”
The floor
It is essential to ensure that the floor
surface can actually bear the weight
of the stove and a top-mounted steel
chimney, if applicable. The stove must
stand on a nonflammable surface
such as a steel floor plate or a brick or
tile floor. The size of the nonflammable
surface used to cover the floor area
must match national and local regulations. (See table on page 9)
The chimney connection
The chimney opening must follow
national and local regulations. The
Inspire 40,45,55, 55H can be installed with a minimum 125 mm to 150
mm flue in accordance to En 13240
testing.
If a damper is fitted in the flue gas
pipe, there must always be at least
20 cm2 of 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 gasfired heater. An
efficient stove makes high demand on
chimney properties – so always have
your local chimney sweep evaluate
your chimney.
Inspire 40, 45 and 55, 55H can be installed with a horisontal straight back
outlet. Maximum length of the pipe
should be 500 mm with a 5” diameter.
The start draft (cold stove) of the
chimney should be at least 6 pascal.
Connection to a brick chimney
Brick a thimble into the chimney and
seat the flue gas pipe in this. The
thimble and flue gas pipe must not
penetrate the chimney opening itself,
but must be flush with the inside of
the chimney duct. Joins between
brickwork, the thimble and flue gas
pipe must be sealed with fireproof
material and/or beading.
Connection to a steel chimney
When fitting a connection from a topoutput stove directly to a steel chimney, we recommend fitting the chimney tube inside the flue gas spigot so
that any soot and condensation drops
into the stove itself rather than collecting on the exterior surface of the
stove. Changing smoke outlet from
top-mounted to rear-mounted (see fig.
8-15 on page 12).
For connections to chimneys that are
run through ceilings, all national and
local regulations regarding distance to
flammable material must be followed.
It is important that the chimney is
fitted 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 combustion in stoves of this kind is 13 PA
for Inspire 40 and 12 PA for Inspire
45 and 55. However, there will still be
a risk of smoke emission if the firing
door is opened during powerful firing.
Inspire 40: The flue gas temperature at
nominal output is 263°C when expelled to an exterior temperature of 20°C.
The flue gas mass flow is 3.7 g/sec.
Inspire 45: The flue gas temperature at
nominal output is 221°C when expel-

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 first firing, which
should be carried out using approximatly 1 kg of wood for Inspire 40 and
45 and approximatly 1.4 kg for Inspire
55 and 55H, the stoking door must
be opened slightly every 10 minutes
for the first two hours to prevent the
sealing rope sticking to the stove.
led to an exterior temperature of 20°C.
The flue gas mass flow is 4.0 g/sec.
Inspire 55/55H: The flue gas temperature at nominal output is 263°C when
expelled to an exterior temperature of
20°C. The flue gas mass flow is 5.7 g/
sec.
The chimney draft is generated by the
difference between the high temperature of the chimney and the low temperature of the fresh air. The length
and insulation of the chimney, wind
and weather conditions also have an
effect 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
when:
• The difference in temperature
is too small – due to insufficient
chimney insulation, for example.
• The outdoor temperature is too
high – in summer, for example.
• No wind is blowing.
• The chimney is too low and sheltered.
• The chimney contains false air.
• The chimney and flue gas pipe are
blocked.
• The house is too airtight (i.e. when
there is an insufficient 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 airflow into the stove.
Good draft occurs when:
• The difference in temperature
between the chimney and outdoor
air is high.
• The weather is fine.
• 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.

Operating Instructions dated July 2015 reference ”Pevex1020/AH/ver2.”
Fuel
Your new stove is EN approved for
firing with wood fuel. You must therefore 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 damage both the stove
and the chimney. Similarly, you must
not fire your stove with refuse, painted
wood, pressure-impregnated wood
or chipboard, as these materials can
emit poisonous fumes and smoke.
Correct firing using well seasoned
wood provides optimal heat output
and maximum economy. At the same
time, correct firing prevents environmental damage in the form of smoke
and emmissions and also reduces
the risk of chimney fires. If the wood
is wet and inadequately 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 seasoned 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 firewood with a diameter of more
than 10 cm should be split before
storing. The pieces of firewood should
be of an appropriate length (approx.
18 cm) so that they can lie flat on the
bed of embers. If you store your wood
outdoors, it is best to cover it.

It is advised not to use very oilcontaining 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
efficiency of about 4.18 kW/hour per
kg, and one litre heating oil contains
about 10 kW/hour.
CO2 release
At combustion 1000 litres of heating oil
forms 3.171 tons CO2. As wood is a
CO2 neutral heat/ energy source, you
save the environment about 1.3 kg
CO2 every time you have used 1 kg
normal wood.

Operating Instructions dated July 2015 reference ”Pevex1020/AH/ver2.”
Chimney fires
In the event of a chimney fire – which
often results from incorrect operation
or protracted firing with moist wood
– close the door and shut off the secondary air supply to smother the fire.
Call the fire department.
Airflow regulation
To adjust combustion airflow, use the
handle at the front under the door.
Combustion air flow is fully open when
the handle is as far as possible to the
right. To close gradually, slide the
handle to the left (fig. 1).
Fig. 1
The Inspire 40/45/55 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
permanent stop is fitted to ensure that
the air control slider cannot be closed
beyond 41% of its fully open position.
A permanent amount of air will therefore enter the firebox to feed the fire
producing 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 fire lighters,
small paraffin 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 firing, doors. Completely open the secondary air supply and
leave the firing door ajar – i.e. approx.
1 cm open. Once the fire has taken a
good hold of the fuel and the chimney
has heated up (after about 10 min)
close the firing door. We recommend
that you burn the entire first firing
with the secondary air supply fully
open to make sure that the chimney is
thoroughly heated.
7
Operating Instructions dated July 2015 reference ”Pevex1020/AH/ver2.”
3. With plenty of air the flames will burn
brightly quickly warming the stove and
chimney.
4. After about 5/10 minutes and with the
fire 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 flames 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 ensuring 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 firelighters on the base of the stove
and stack some small pieces of wood/
kindling on top into about 3 layers leaving gaps in between.
2. Fully open the air control. Light the
firelighters and leave the door slightly
ajar to allow air to enter and the fire to
establish.
8
Operating Instructions dated July 2015 reference ”Pevex1020/AH/ver2.”
Once the flames have taken hold, the
air supply can be regulated to give the
required amount of heat.
Note:
If the fire dies down completely or
embers are smoldering then it will be
necessary to place some screwed up
paper or firelighters onto the grate
with some kindling or small pieces
of wood to reestablish the fire once
again. Leave the airslider fully open
and allow the fire to build before
refueling with larger pieces of wood
and then adjust the slider for optimum
combustion.
Do not overload the firebox by
loading above the tertiary air diffuser at the back of the firebox 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: Operation 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 completely open: Operation with the airsliders permanently open can cause
excess smoke. The appliance must
not be operated with air controls or
dampers left open except as directed in the instructions.
Refuelling
You should normally refire the stove
while there is still a good layer of
embers, using pieces of firewood with
a diameter of not more than 10 cm
and not longer than 25 cm. Distribute
the embers across the bottom grate,
place pieces of fuel (approx. 1.3 kg for
Inspire 40/45 and approx. 1.5 kg for
Inspire 55 and 55H) on the embers in
a single layer perpendicular to the firing opening. Close the firing 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
flame, adjust the secondary airflow to
the level required. For nominal operation, the secondary air supply should
be 65% open. When firing, take care
not to place the pieces of fuel too closely together, as this will result in poor
combustion and insufficient exploitation of the fuel.
Reduced burning
The stove is well suited to intermittent use. If you wish to operate the
stove with reduced output, simply
insert smaller volumes of wood at
each firing, and apply a lower airflow.
However, remember that the secondary combustion air supply must never
be shut off completely during firing.
It is important to keep a good bed of
embers. Gentle heat is released when
the fire settles - i.e. when the wood no
longer generates flames and has been
converted to glowing embers.
9
Operating Instructions dated July 2015 reference ”Pevex1020/AH/ver2.”
Optimal firing
To achieve optimal firing and the
highest possible effect, 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 fire to ignite the flue gases. This
produces a high effect 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 secondary 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 firing 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 unattended 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 stove. This may result in the production
of large volumes of gas, and this gas
can explode if the intake of secondary
air is insufficient.
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.

Operating Instructions dated July 2015 reference ”Pevex1020/AH/ver2.”
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 chimney sweep. In the event of smoke or
malodorous fumes being produced,
you must first check to see whether
the chimney is blocked. The chimney must, of course, always provide
the minimum draught necessary to
ensure that it is possible to regulate
the fire. 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 fit a damper in
the flue 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 correctly fitting.
If the stove it generating too little heat,
this may be because you are firing
with wet wood. In this case, much of
the heating energy is used to dry the
wood, resulting in poor heating economics 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 regulations (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 required (4.5kW x 550mm = 2475mm2)
unless the stove is connected to an
outside fresh air supply.

The Clean Air Act 1993 and Smoke
Control Areas
Under the Clean Air Act local authorities may declare the whole or part
of the district of the authority to be a
smoke control area. It is an offence to
emit smoke from a chimney of a building, from a furnace or from any fixed
boiler if located in a designated smoke
control area. It is also an offence to
acquire an ”unauthorised fuel” for use
within a smoke control area unless
it is used in an ”exempt” appliance
(”exempted” from the controls which
generally apply in the smoke control
area).
The Secretary of State for Environment, Food and Rural Affairs has
powers under the Act to authorise
smokeless fuels or exempt appliances for use in smoke control areas in
England. In Scotland and Wales this
power rests with Ministers in the devolved administrations for those countries. Separate legislation, the Clean
Appendix A
Air (Northern Ireland) Order 1981, applies in Northern Ireland. Therefore it
is a requirement that fuels burnt or obtained for use in smoke control areas
have been ”authorised” in Regulations
and that appliances used to burn solid
fuel in those areas (other than ”authorised” fuels) have been exempted
by an Order made and signed by the
Secretary of State or Minister in the
devolved administrations.
The Inspire 40/45/55/55H have all
been recommended as suitable for
use in smoke control areas when burning dry wood logs.
Further information on the requirements of the Clean Air Act can be
found here : https://www.gov.uk/
smoke-control-area-rules
Your local authority is responsible for
implementing the Clean Air Act 1993
including designation and supervision
of smoke control areas and you can
contact them for details of Clean Air
Act requirements.
