Congratulations on the purchase of
your new InisBofin room-heating
insert stove. We here at Inis
Stoves truly love building high
quality stoves for our customers.
The stove we produced for you was
not just an appliance to us; we
hope that you will see it as a
focal point in your home. When
fitted, and operated correctly,
you should enjoy many years,
trouble free warmth from your
InisBofin insert stove.
Please read the user manual fully
before operating the stove.
Safety Notice
Fireguard
Ensure that a certified fireguard
is always used where the elderly,
infirmed or children have access
to the stove to prevent burning.
Proper supervision of the elderly,
infirmed or children around the
stove is required at all times and
please be aware that the stove
remains hot for many hours after
the fire has gone out.
CO and Fire alarm
Inis Stoves highly recommend the
fitting of fully certified CO and
fire alarms and regularly check
that the alarms are operational
for the proper protection for you,
your family and your home.
Ensure that the installer of this
stove is fully qualified.
Fume emissions into the room
must not be tolerated.
If this happens close the door of
the stove, open up some windows,
close the damper and let the fire
out. Call a qualified chimney
expert to ascertain the problem
before lighting the stove again.
Chimney fire.
In the event, you believe there
may be a chimney fire, close the
stove door, close the damper and
allow the fire to die out. If you
still believe a fire exists, call
the fire brigade immediately.
After a chimney fire, the chimney
must be examined by a chimney
expert
before using the stove again.
Paint curing
For the first couple of firings of
the stove, the stove will emit an
odour as the paint cures, open
windows and if necessary vacate
the room until the fumes subside.
The fumes are non-toxic.

InisBofin Insert Roomheater
Stove Features
As per Fig 1 below the door of the
stove is opened by inserting the
narrow end of the hand tool into
the door latch and lifting the
handle upwards. The hand tool in
this position can then be used to
move the door as required.
As can be seen in Fig 2 above, the
riddling mechanism is located on
the left-hand side of the stove
towards the bottom of the facade.
To operate the riddling mechanism,
insert the tool into the
rectangular slot as shown. When
the hand tool faces downward at 45
degrees the riddling grate is in
the closed position. This position
is used when burning wood logs.
When the hand tool is raised fully
up at 45 degrees, the grate is in
the open position while burning
wood logs. To riddle the grate,
use the riddling hand tool and
gently oscillate the riddler back
and forth. Avoid using excessive
force to avoid damaging the
riddling mechanism.
Normally it is advisable to have
the doors closed at all times
except when re-fueling, de-ashing
Fig 1
Fig 2

InisBofin Insert Roomheater
and when igniting the stove. If
excess fuming to the room results
at any time when the door is
opened, it should be closed
immediately and expert help
sought.
The stove has been designed for
ease of use by the operation of
just one air control slider. The
damper slider governs all the air
flows throughout the stove for
optimum efficiency and
performance. This adjustment
slider is found on the top of the
stove to the left side of the
facade. To operate the damper
slider, use the hand tool to move
the slider to the left side to
close the damper and to the right
side to open the damper. No
adjustment of the damper assembly
is necessary. To help keep the
stove glass clean, load the fuel
toward the back of the stove when
lighting and use kindling which
lights quickly and fire the stove
at a high rate for 25-30 minutes
after lighting. To avoid
blackening of the glass avoid
prolonged periods at a very low
setting.
Paint Curing
Please adhere to the curing
procedure described below as over-
firing the stove before the paint
has cured will lead to fading of
the paint and this is not covered
by your warranty.
When the stove is used for the
first number of times the process
of curing the paint will occur. To
do this a small fire using only
kindling wood logs should be
started for approximately 30
minutes, allow the stove to cool
slightly then repeat the small
fire using only kindling wood logs
for another 20 minutes. The final
action to cure the paint is
to put on a normal sized fire
before the stove has cooled down,
at full output for at least one
hour. The stove paint will emit
fumes with are non-toxic but a
window should be opened to avoid
fume build up during the curing
process.
Before you operate the stove,
consult with the installer that all
the relevant work has been carried
out correctly and that they have
ignited a small fire in the stove
and it is operating correctly.
Check that all relevant local,
national and European Standards
have been adhered to when
installing the stove.
Attention: The insert is designed for intermittent
Operation, i.e. normally a new load of fuel is
loaded after the previous one has burned
completely.
General Points
1. Never use unsuitable and non-
recommended fuels, including
liquid fuels in the stove and
don’t use the stove as an
incinerator
2. When in operation, the stove
will be hot and care should
be taken to avoid injury.

InisBofin Insert Roomheater
3. Never attempt to modify the
stove in any way and always
use genuine Inis Stove spare
parts.
4. Never place combustible or
non-combustible materials
near, in or around the stove
that will interfere with the
proper heat convection and
air supply to the stove. The
stove surround should be
fireproof. Never leave the
stove fuels too close to the
stove.
5. For safe and efficient
operation of the stove,
regular cleaning of the
stove and chimney is
essential. Dirty surfaces
within the stove will lead
to poor heat transfer to the
room and will waste your
money.
6. Care should always be taken
when emptying the ash pan of
the stove. Hot ashes should
never be put in a plastic
dust bin, bag or container.
Ideally, empty the ash pan
when the ashes are cold.
7. Inis Stoves is dedicated to
the principal of using wood
logs in all our stoves.
Using wood logs as fuel goes
a long way in reducing your
homes heating carbon
footprint and also reduces
our dependence on imported
energy. We recommend using
nationally sourced wood logs
in our stoves.
8. To refuel the fire, open the
door and place the fuel in
the firebox. Avoid putting
too much wood logs in the
stove at the same time as
this can result in over
firing of the stove.
9. Never burn household waste
in the stove.
10.Never burn petroleum coke in
Stove as it will invalidate
the guarantee.
Fuels
Inis Stoves recommend that wood
logs be used to fuel the stove.
If possible, always use light dry
kindling when lighting the stove.
Wood with a maximum moisture
content of 20% should be used. If
the moisture content is any
higher, the fire will produce much
less heat than is possible and the
stove glass, stove and chimney
flue will build-up tar deposits.
The wood logs should have a
maximum diameter of
approximately 100 mm.
Don’t burn coal pellets or coal
dust. Burning slack is not
recommended.
Try and ensure the wood logs is
not wet when fueling the stove.

InisBofin Insert Roomheater
Lighting the fire
The key to quick and easy lighting
of the stove is the ample use of
kindling wood logs. If too little
kindling is used, the fire will be
slow to start and will produce
excessive smoke and deposits on
the glass.
The grate should be put in the
open position (handle up).
Firelighters or well crumpled
paper should be surrounded with
small pieces of kindling toward
the back of the grate.
Light the fire and with the door
lock engaged but the door slightly
ajar let the fire light up. After
the kindling is well alight add
larger pieces of fuel to the fire
and after a few more minutes this
fuel should be well alight. The
stove can be fully loaded now and
a bright high temperature fire
should result. Once the fire is
well alight the door can be fully
closed. Since Wood logs are used
the grate needs to be closed.
The stove damper will normally
not require adjustment down until
after approximately half an hour
to forty-five minutes, as the
stove will take this time to
fully heat up. Under normal
conditions the damper will
be moved to about 8mm along the
slider for optimum operation.
Firing &
Refuelling
Do not let the fire burn down too
low before refueling as the new
fuel will smoke excessively and
will require a long time to become
fully alight. Open the damper
fully every time you refuel the
stove for at least five to ten
minutes to aid rapid lighting of
the new fuel (not necessary when
using dry wood logs). This will
help prevent excessive smoking and
will help to keep the stove and
the glass clean. Once the new fuel
is well alight, the damper can be
adjusted down to an appropriate
setting.
Slow burning
Your InisBofin is capable of slow
burning making overnight burning
possible at a reduced output. To
achieve overnight burning, open the
damper fully and fill the firebox
with a full charge of fuel and let
it ignite fully. When the fire is
burning brightly, the stove damper
can then be closed down. With the
damper almost fully closed and the
correct draft in the chimney, an 8-
12 hour burn time is possible. For
more heat output over
a shorter time span the damper can

InisBofin Insert Roomheater
be opened up as necessary. To avoid
excessive blackening of the glass
the damper should be left slightly
open.
To revive the fire after overnight
burning, riddle the grate, refuel
the firebox with a small amount of
light kindling fuel and open the
damper fully. A strong fire for at
least twenty minutes is required
to burn off excess build-up of
soot deposits after a prolonged
period at low output.
Please bear in mind that operating
the stove at very low outputs is
not the most efficient way to burn
the fuel and the stove and chimney
will require more cleaning when
the stove is operated this way.
Ash clearance
The stove has one ash pan designed
for ease of handling. The ash pan
should be emptied before it gets
over filled to protect the grate
from over-heating. The ash is an
excellent insulator and excess
build-up of ash will cause grate
damage.
Great care should be observed when
emptying the ashes as it can be
very hot and it could start a fire
if it comes into contact with
combustible material like plastic
bins etc.
Stove cleaning and
maintenance
Regular cleaning is essential for
safe and efficient operation of the
stove.
During the heating season, it is
recommended to clean the stove
weekly or fortnightly. Inspect on a
regular basis the condition of the
door seal and if found to be worn
replace it immediately.
Only clean the stove when it is
fully cold. A Pair of gloves should
be used when cleaning the stove and
care should be taken to avoid
injury as a number of the stove
components are quite heavy.
To remove the baffle assembly, see
Fig 3. First removing the firebox
side plates. Lifting the baffle up
slightly and taking out the firebox
side vermiculite pieces with the
use of a flat screwdriver. With the
side sections removed the baffle
and front support clip can be
lowered and removed by lifting it
up slightly at the front and drop
the rear part first. Then twist the
baffle sideways to remove. Access
to the flue outlet is now possible
for cleaning and the chimney can be
cleaned up through the stove. To
clean the air pathways within the
stove, see Fig 4.
1. Remove the firebox side
plates.

InisBofin Insert Roomheater
2. Remove the riddler bars starting
at the front and working back
3. Lift out the ash pit rear
vermiculite section and the ash pit
rear plate that is located
underneath the vermiculite plate.
Vacuum out all visible ash (Fig 5)
thoroughly. Re-assembly is the
reverse of dis-assembly.
4. Check that the riddler mechanism
operates free and clear.
Inis Stoves highly recommends
annual servicing of the stove as
the service engineer will ensure
correct and thorough cleaning of
the entire stove.
Inspect all internal parts of the
stove and replace if needed.
Only Inis Stoves or an approved
Engineer on our behalf should
modify the stove in any way.
Fig 4
Fig 5
Fig 3

To clean the paint of the stove we
recommend the use of a damp cloth
containing some mild detergent.
Avoid using abrasive material on
the paint of the stove.
If the stove is to be unused for a
prolonged period of time, for
instance over the summer months,
the stove should be fully cleaned
and a lubricant applied to all
moving parts. The damper may be
left slightly open to facilitate a
little air movement through the
stove and avoid moisture build up.
Avoid excess opening of the damper
as this will result in excess heat
loss through the stove up the
chimney. After a prolonged period
being unused, inspect the chimney
before use to ensure no blockage
has occurred. Also ensure that the
air vent to the room of the stove
is clear.
Trouble shooting
NOTE: Excess fume
emission to the room
must not be tolerated.
Fire burns very rapidly and
refueling periods are not being
met.
1 Chimney draught is very high,
chimney damper may be required.
2 Fuel load too small for damper
setting.
3 Door seals are worn.
4 Adjust the damper to a lower
setting for proper fire control.
Fire will not burn properly
1 Chimney draught is too low
2 Damper is closed
3 Chimney height too low,
flue/chimney seals leaking
4 Chimney blocked, damaged
5 Ash covering all air ways into
firebox
6 Fuel is wet
7 No Vent present in room
Stove emits fumes
1 Chimney blocked
2 Door seals require replacing
3 Excess down drafts in chimney
4 Chimney draughts below 10Pa.
5 Extractor fan effecting stove.
When burning, wood logs the grate
must always be kept in the open
position. The grate can be riddled
Inis Bofin Insert Roomheater

InisBofin Insert Roomheater
by oscillating the grate back and
forth without excessive force
being used. The grate is not
designed to fully close when
burning wood logs. If the grate
jams it may be due to a foreign
particle like a stone or nail
jamming the riddler action. To
clear a jam, let the stove
completely cool down, remove the
firebox side plates and remove the
riddler bars starting at the
front. Clear any ash and particles
and reassemble the riddler
assembly. The problem will usually
be solved by this process.
Glass blackens excessively
If the stove is fitted correctly
and the correct lighting and
operation of the stove is adhered
to, blackening of the glass should
always burn off after a period of
full output. A poor draught and or
the use of wet or improper fuel
will often lead to excessive glass
blackening. Often clean glass
operation will be attained with a
little experience of operation.
Chimney fire
If the stove and chimney are
kept clean, no fire should
occur. If however it does
happen, close the stove damper
fully, close the stove door
tightly. Only once the fire in
the stove and chimney has gone
out should the stove be opened
and the stove and chimney
cleaned thoroughly. If the fire
is substantial and doesn’t
extinguish, the fire brigade
should be called. After a bad
chimney fire, expert help should
be sought to have the chimney
examined for any damage before
the stove is used again.
Heating during adverse
weather conditions
In certain cases, e.g. when
ambient temperature is above
15degC. The weather is rainy and
damp, or when a wind is gusty
etc., the chimney draught might be
worse than usual. In such cases a
minimum amount of wood logs should
be used in the fireplace and the
initial air supply valve should be
fully opened.

Installation Instructions

InisBofin Insert Roomheater
In addition to installation
instructions supplied, the
requirements of BS.8303 and
BS.6461 Parts 1&2; 1984 must be
fulfilled. Also all local
authority bylaws and domestic
building regulations including
those referring to national and
European Standards regarding the
installation of solid fuelled
burning appliances, flues and
chimneys must be followed.
This stove is designed only to be
installed in a fireplace with a
chimney.
Stove preparation
The crate should be carefully
unscrewed to avoid possible damage
to the stove. The stove hand tool
should be taped to the top of the
stove along with this manual.
Remove the plastic packaging. Use
a screw driver to remove the screw
holding the stove in place. The
wooden crating the stove was
shipped in can be cut up for fuel
in the stove. Take great care to
avoid damaging the damper
mechanism on the underside of the
stove when removing the stove from
its shipping crate and moving it
into position.
To help with fitting of the
stove, the stove door and facade
and baffle assembly should be
removed. The door is removed by
opening the door and lifting up
approx. 20mm until the hinges are
clear and lift away. Take great
care not to drop the door as it is
quite heavy and the door glass can
easily be broken. The facade is
removed (See Fig 6) by removing
the indicated split pin with the
use of a pliers, gently but firmly
lift the facade approx. 5mm by
holding towards the left and right
sides of the façade along the top
to avoid deforming the facade in
the middle.
Remove the baffle assembly as
shown in the user manual and
remove the firebar and ash pan.
With the baffle assembly removed
the flue collar can be removed
prior to fitting of the stove.
Chimney
Chimneys must satisfy standard EN
15287:2007. A draught test should
always be performed prior to the
fitting of the stove to ensure
that a proper draw in the chimney
is present (Min 10Pa constant). A
chimney height of at least 4m from
the top of the stove must be used.
The chimney diameter must be at
least 150mm. The chimney must be
in good condition, be cleaned and
free from cracks and blockages.
The chimney must not have too
great a cross sectional area
(250mm Diameter) and if it has

InisBofin Insert Roomheater
the chimney should be lined with a
suitable flue liner for wood logs.
All chimneys and flues used must
be sealed for the best possible
performance. The draught in the
chimney must be at least 10
Pa when warm and must not suffer
from down draughts and if there is
an excessive draught in the
chimney a draught stabiliser
should be fitted. If any doubt
exists please contact a chimney
expert. If it is an existing
chimney that has been is use with
an open fire, the chimney must be
thoroughly cleaned and inspected.
Two to three weeks after the stove
has been in use, have the chimney
cleaned again as soot previously
secure may come loose as the flue
gas from the stove is quite
different than that from an open
fire.
Hearth and Fire Surround
If the installer has any doubts as
to the positioning of the stove
and necessary fire proofing,
expert advice should be sought
before any work begins. The stove
must be placed onto a fire proof
hearth of at least 12mm in depth
that is flat and level. The stove
positioning and hearth size are
governed by building regulations
The Platform on which the insert
is mounted should be stable and
strong to hold the weight of
insert room heater.
Fig 6

InisBofin Insert Roomheater
for class 1 appliances. As can be
seen below in Fig 7 the minimum
sizes of the opening are shown
with minimum hearth thickness.
Fig 8 shows the minimum distances
to combustibles.
Fig 7
Fig 8

InisBofin Insert Roomheater
The minimum depth of the recess
for the stove from the front face
should be 365mm. In most cases
this will require that the
fireback is removed and any loose
material removed. The distance
from the face of the fireplace to
the centre of the flue should be
checked to verify it is between
230mm and 330mm. Please ensure
that the stove in the recess sits
flat with the hearth.
Stove Fitting
There are two main methods of
connecting the stove to the
chimney. Method 1 is to use a
closure pipe adaptor section and
an extension piece. Method 2 is to
line the chimney with a suitable
152.4 mm liner for solid fuel
and connecting to the stove
with a solid section
connector.
Method 1.
The closure pipe adaptor section
of flue should have an offset
built in to allow for the
difference in depth from the front
face of the fireplace to the flue
outlet on the stove. Once the
closure pipe adaptor has been put
in the correct position, fire
cement should be used to make a
tapered seal between the clay
liner and the adaptor to ensure
any condensate or rain will flow
into the flue and not down around
the stove body. The extension
piece of flue is now pushed fully
up onto the closure adaptor to
allow for the stove to be
positioned into the proper
position. Please note that the
extension pipe must fit OVER the
bottom end of the closure adaptor
pipe. The stove facade should be
offered up to the stove at this
point to ensure proper depth
placement of the stove. Now pull
the extension pipe down through
the stove and using fire cement
fit the flue collar to the end of
the extension pipe and when fully
sealed, push the flue collar up
into position and bolt into place.
Check that the joints are all
fully sealed with fire cement and
haven’t being damaged during
fitting. Finally fit the facade
onto the stove ensuring that the
damper mechanism is free and clear
in operation.
Method 2.
The stove it placed in position
and the facade is placed on the
stove to check that the depth of
the stove into the recess is
right. A straight section of solid
fuel flue pipe approx. 152.4-
203.2mm long with a flexible liner
adaptor on the top of it should be
mounted to the bottom of the
flexible liner and fully tighten
the holding screws on the adaptor.
Push the
flexible liner and straight pipe

InisBofin Insert Roomheater
section down the chimney and pull
down onto the flue collar. The
flexible liner MUST fit into the
adaptor on the straight flue piece
not over it. Using fire cement
mount the flue collar onto the
bottom of the straight pipe
section and bolt the flue collar
into place with the two bolts
provided. Check that the joints
are all fully sealed with fire
cement and haven’t been damaged
during fitting in place. Finish
the installation of the flexible
liner at the top of the chimney as
per the manufacturer’s
instructions. Finally fit the
facade onto the stove ensuring
that the damper mechanism is free
and clear in operation.
-----------------------------------------------------------------------------------------------
Method 1

InisBofin Insert Roomheater
Method 2
Air Requirement
Due to the increase in building
air tightness particular attention
must be paid to the availability
of sufficient combustion air, for
the safe and proper operation of
the stove. A minimum of 75 sq. cm
of vent is required for the stove.
The vent must be of a permanently
opened design. It must cross the
cavity to the outside, on external
walls and must be weather
resistant to prevent in ingress of
moisture. The vent must not be
located at a position in the room
that will result in an air current
traversing through normally
occupied areas of the room.
Care must also be taken to ensure
that the vent cannot be blocked by
object left against the wall
outside or debris like leaf litter
etc.
A larger vent is required if there
is an appliance like an extractor
fan or tumble drier in an
adjoining room. To ascertain if
more venting is required, these
appliances should be operated
together and all external windows
and doors closed to detect
spillage into the room from the
stove. If a chimney draught
stabilizer is fitted to the
chimney, a larger vent is required
of at least 8.5 sq. cm per Kw of
output over 5kw.
