Occasionally fumes from refuelling may occur.
However, persistent smoke or fume emission
is potentially dangerous and must not be
tolerated. If this persists, then the following
immediate action should be taken:
• Quickly open the doors and windows
to ventilate the room.
• Make sure that the stove door is closed and
that the combustion air control is fully open.
It may be that the open door or a fully closed
control have contributed to the problem. The
above actions should then ensure that any
remaining fuel will combust as normal and
will not smoulder to create more unwanted
smoke or fumes.
However, if smoke and fumes persists then
leave the premises and let the fire go out.
• Wait until the room clears and the stove
is cold.
• Check for a flueway, connecting flue pipe or
chimney blockage and clean out if required.
• Check that the wood logs you have used
are fully seasoned with a moisture content of
less than 20%. Wet wood will always produce
excessive smoke as well as create an acrid
smell.
• Do not attempt to relight the fire until the
cause of the smoke or fume emission has
been identified and corrected. If necessary
seek expert advice, preferably from a Hetas
installer.
The most common cause of smoke or fume
emission is flueway or chimney blockage. For
your own safety these should be inspected
regularly and must be kept clean at all times.
See page 32.
If the CO alarm (which should be fitted at the
time of installation) sounds, please follow the
advice above.
A WORD ABOUT TODAY’S HIGHLY
SENSITIVE SMOKE DETECTORS AND
CARBON MONOXIDE (CO) ALARMS
It’s good to know that we can all depend
upon today’s highly efficient smoke alarms
and carbon monoxide detectors to ensure our
safety. However, it is worth pointing out that
when you light your stove for the first five or
six times the fumes from the new paintwork,
as it cures, may cause the smoke alarm to
sound. This can usually be prevented by
greatly increasing the ventilation to the room
during the paint curing process.
In new build properties smoke alarms and
CO detectors are often interlinked and will
sound throughout the home when either one
of them detects an issue, such as fumes from
paintwork curing. Again, when using the stove
greatly increase the ventilation in the room to
help prevent this.
Should the alarm soundings continue beyond
the first five or six firings and / or not respond
to increasing the ventilation then, in the first
instance, please consult your stove installer or
property developer.
IMPORTANT: USER WARNING NOTES
Properly installed, operated and maintained this stove
should NOT emit smoke or fumes into the dwelling.

CRITICAL SAFE DISTANCES
Fireplace Openings
When this stove is installed
within a fireplace opening
the appropriate air space must
be provided to ensure the free
movement of the radiated heat
and hot air. If this is restricted
it could affect the stove’s safe
and efficient operation as well
as shorten the lifespan of the
stove components and, in
particular, the vermiculite
insulating panels and baffle
plate. Reducing these distances
could also create ‘hot spots’
which could potentially damage
the fabric of the fireplace or
chimney breast.
Recommended Minimum
Air Space inside a Fireplace
Sides 125 mm (5”)
Rear 75 mm (3”)*
Top 200 mm (8”)
*To ensure the stove’s safe operation when
not using the direct external air supply (DEAS)
you must allow sufficient space for the free
movement of air around the rear air inlet at
the base of the stove (this supplies all of the
combustion air to the stove).
If space is limited between the back of the
stove and the rear wall of the fireplace then,
if necessary, it is acceptable for the installer
to trim the air inlet to provide the required
35mm gap between the inlet and the wall to
ensure an ample air supply. Under no
circumstances should the air inlet butt up
against the fireplace wall. When using DEAS
you must allow clearance space for any non-
combustible ducting.
Always Allow Space for Maintenance
You must leave sufficient space around the stove
to allow easy access for regular maintenance.
A
B
C
This is particularly important if you intend to
use the rear fitting flue option with a T-piece
flue pipe as you will need to be able to access
the T-piece trap and be able to easily and
securely refit the cap after cleaning.
Min’ Distances to Combustible Materials
Rear 300 mm (12”)
Sides 500 mm (20”)
Hearth requirements
CE tested maximum surface temperatures:
Floor below the stove 46ºC
Floor 500mm in front of the stove 58ºC
Floor 1,000mm in front of the stove 57ºC
NB Temperatures above are from the R6
model tests. Temperatures for the R6-LS, with
its firechamber placed much further away from
the floor surface, will be less. Both the R6
and R6-LS stoves are therefore suitable to be
placed on a 12mm non-combustible decorative
hearth subject to Building Regulations. Please
refer to current Building Regulations for all
specific fireplace and hearth safety requirements.

R6 STANDARD FEATURES
1 Combustion Air Control
For ease of use, there is only one combustion
air control on the R6 wood burner. This will
deliver both the correct mix of primary air
(required at the ignition stage) as well as
the pre-heated secondary air supply which
controls the airwash system and the flame
pattern when the logs are fully alight. Pre-
heated secondary air ensures that there is no
incoming cold air to cool the firechamber and
reduce the stove’s efficiency.
2 Pre-heated Tertiary Air System
Pre-heated air enters the stove through jets in
the tertiary air bar at the rear of the firechamber.
By introducing a new supply of warm
combustion air just as the flue gas is about to
leave through the flueway this ensures even
more unwanted particulates are burned off
helping to keep emissions to a minimum.
3 Airwash System
Part of the secondary air control system which
diverts pre-heated air down along the front of
the glass to burn off unwanted dry sooty
particulates and help to keep it clean. Burning
wet or unseasoned wood will reduce the fire-
chamber temperature and cause the airwash
system to fail leaving tarry condensates on the
glass which will be difficult to remove if left.
4 Top or Rear Flue Options
Factory set for the preferred top flue outlet.
However it is very simple to switch over
depending on your type of installation.

PACKING LIST
Check that you have a full set of components
shown in the list below. Some components
may be contained inside the firechamber. In
the unlikely event of a shortage, please report
this immediately to your stove dealer. Never
attempt to operate the stove with missing or
damaged components.

ASSEMBLING THE STOVE
Your new Hi-Flame stove is extremely heavy.
Always handle it with care and make sure that
you have additional strong help when you
move it. The door and door handle, should
not be used to grip the stove as they could be
damaged from supporting the stove’s weight.
If necessary, the fuel retaining bar can be
removed to help reduce the weight. Under no
circumstances should the door be removed as
this will invalidate your Hi-Flame Warranty.
• Unpack Remove your new stove from its
recyclable packaging. Retain this until the
stove is installed and is fully operational.
Unfasten retaining wires and remove any
components from inside the stove.
• Inspect Please inspect the stove to check
that it has not been damaged in transit –
never attempt to install a stove which has
been damaged. If damage is suspected then
report this immediately to your stove dealer.
• Baffle Plates There are two baffle plates.
The lower baffle plate is made of vermiculite
and the upper baffle plate is made from plate
steel. Check the position of both baffle plates
to ensure that it they have not moved when
the stove was transported. Essentially they
should be securely positioned parallel to each
other. For more detailed information about fitting
and removing the baffle plates see page 32.
12
Fully familiarise yourself with the correct location
of the baffles by practising removing and re-fit-
ting them prior to the stove’s installation as you
will need to regularly check this area to avoid
potential soot build up and blockages.
• Flue Outlet Options This stove is
already configured for the preferred top flue
outlet, however it can easily be switched to
the rear fitting flue option. To do this, firstly
remove the rear heat shield using the correct
sized allen key. The heat shield has a pre-cut
flue outlet aperture which can be removed by
using a junior hacksaw blade to carefully cut
through the small retaining links. Next remove
the rear flue outlet closure plate at the back
of the firechamber, being careful not to damage
the gasket seal or the bolts. Remove the top
flue collar, again being careful not to damage
the gasket seal or bolts. Swop over the flue
collar and closure plate ensuring that both
make a perfect all-round seal with the stove
body. Lightly lubricate all bolts with machine
oil to avoid damaging the screw threads. Fi-
nally, re-attach the rear heat shield.Your stove
is now ready for installation.
• Moving Do not drag the stove. Always lift it
to finally position it and use strong help. Alter-
natively it may be possible to place the stove
on heavy-duty plastic sheeting or thick floor
covering to slide the stove into position, being
careful not to damage any finished hearth or
floor surfaces with trapped grit or debris.
Remove the pre-cut
aperture on the rear heat
shield to access the
optional rear flue outlet

BASIC INSTALLATION CHECK-LIST
This information is intended to outline the
general principles of installing your stove.
However, as each installation will vary it is
unfortunately not possible for these guidelines
to be comprehensive.
• Not only is it a legal requirement to ensure
that your stove installation complies with all
applicable Building Regulations, it is also a
requirement of your Hi-Flame Warranty that
the stove is installed by a competent person
such as a Hetas registered installer. They will
be fully aware of any building and safety
regulations which apply to stove installations
in your location.
• The existing constructional hearth and
back hearth upon which the stove will sit is
suitably constructed and is made from a non-
combustible material of the correct thickness
so that it conforms to all applicable Building
Regulations. The superimposed hearth (the
thinner, usually decorative surface, which sits
on the constructional part of the hearth) is
suitably constructed and conforms to all
applicable Building Regulations.
• The fireplace recess or opening is suitably
constructed and any new lintel conforms
to all applicable Building Regulations. The
recess should be able to accommodate the
stove along with the safe minimum operating
distances required (see page 8). Any fireplace
lining should have the appropriate fire rating.
NB Plasterboard is not a suitable lining.
• Any adjacent walls, next to which a free-
standing stove is installed, should be of a
suitable thickness, made of an appropriate
non-combustible material and conform to all
applicable Building Regulations.
• The chimney is of sufficient height and is in
good condition and conforms to all applicable
Building Regulations for stove installation.
Please refer to the to current issues of
BS EN 15287-1:2007 Design, installation and
commissioning of chimneys.
NB The minimum flue height required for this
stove is 4.5 metres (15’). For shorter flues,
the calculation procedure outlined within BS
EN13384:1 may be used to determine whether
a proposed flue design and height is capable
of providing sufficient flue draught.
• Sweep and test the chimney prior to installation.
• The proximity of all combustible materials to
the intended stove installation must conform
to the minimum requirements outlined within
this handbook (see page 8) as well as local,
national and European Building Regulations,
whichever is the greater. A combustible material
is anything which can burn once it gets hot
enough and includes plasterboard, skirting
boards, wooden fire surrounds, wooden
mantles, wallpaper, fabrics and floor coverings.
Remember these materials could be concealed
behind other materials which on the surface
may appear to be non-combustible, for example,
plasterboard and stud partitioned walls.
• You must ensure that this stove receives an
adequate air supply for its safe performance.
In a post-2008 home this must be from either
a permanently open air vent or via the stove’s
direct external air supply. See panel overleaf
for houses with MVHR systems. Additional
information on air supply requirements is also
available on page 34.
ENSURING A SAFE AIR SUPPLY WHEN
MECHANICAL EXTRACTION IS PRESENT
Potential depressurisation caused by
extractor fans etc must be assessed for
any risks and the appropriate ‘worst case
scenario’ spillage tests and flue draught
measurements must be undertaken by an
appropriately qualified installer during the
commissioning process. See the section on
Commissioning on page 37.

GENERAL INSTALLATION GUIDELINES
Due to the wide variety of installation locations
and types this information should only be
considered as general guidance – you must
always refer specifically to current Building
Regulations which apply to your country or
region. For a list of these see page 13.
The Hearth
This stove can be installed on a 12mm thick
non-combustible decorative hearth subject
to Building Regulations. The hearth must be
capable of supporting the weight of the stove
(when loaded) along with any flue components
which may bear down on the stove.
In England and Wales when this stove is used
in a fireplace there is a requirement for the
hearth to project a minimum of 225mm (9”)
in front of the opening or jam and not less
than 150mm (6”) at each side of the recess.
When using as a free-standing stove please
refer to current Building Regulations for
hearth dimensions. In addition any hearth
must provide protective coverage for the
minimum clearance distances for this stove
outlined on pages 7 and 8 and should also
extend by a minimum distance of 225mm
(9”) from the front edge of the stove. The wall
behind the stove should be non-combustible
or alternatively be adequately protected from
heat from both the stove and flue pipe.
The ‘Fireplace’
The stove can be sited within a brick or stone
fireplace recess or used free-standing. The
fireplace side and rear walls should be at least
75mm thick and made of non-combustible
brick or stone. Adequate air space around the
stove will allow the stove to radiate heat and
circulate warm air around the room must be
provided. This will also prevent any structural
damage to the fireplace walls as well as help
avoid potentially over-heating the stove and
damaging components. For recommended safe
distances when this stove is located inside a
fireplace – see pages 7 and 8. Please note
if the fireplace interior needs to be lined you
must not use standard plasterboard as this is
combustible. Any sheet materials, the supports
used behind it and fitting components should
have the maximum possible fire rating.
Installing inside a Mock Chimney Breast
if you propose to install this stove within a
mock chimney breast and fireplace then
extreme care must be taken in all instances to
provide the safe minimum distances. Particular
attention should be paid to ventilating the
structure in order to prevent any potentially
dangerous build up of heat inside the structure
or to any of its metal fixings. Ideally, the use
of combustible materials should be avoided
and any sheet materials used should have the
maximum possible fire rating. Please note
standard plasterboard is a combustible
material and should never be used.
The Chimney, Flue and Flexible Liners
Other appliances should not share or be con-
nected to the same flue system or chimney.
If you are using an existing chimney check its
condition and suitability (see below) and, in
the interests of safety, ensure that it is swept,
even if the chimney has never been used
before or you intend to use a flexible liner.
The minimum flue draught requirement for
this stove is 12Pa and the minimum flue
height required for this stove is 4.5 metres
(15’) from the top of the stove to the top of
chimney terminal.
Alternatively, the calculation procedure
outlined within BS EN13384:1 may be used
to determine whether any proposed flue
design and height is capable of delivering the
minimum 12Pa updraught required for the
safe performance of this stove. A copy of the
installer’s flue calculation will be needed as
part of the Hi-Flame warranty registration for
15

an installation where the finished flue height
would be less than 4.5 metres. Failure to satisfy
this requirement could result in the installation
failing the commissioning and spillage tests
outlined elsewhere in this handbook (see
pages 35 to 38) as well as invalidate your
extended Hi-Flame Warranty.
This stove features optional top or rear
125mm (5”) diameter flue outlets and as a
Defra Approved Smoke Exempted Appliance
the connecting flue pipe and stainless steel
flue liner can also of 125mm diameter
(subject to Building Regulations)
Under no circumstances should the stove’s
125mm diameter flue be reduced in any part
of the flue system as this could cause a build
up of dangerous carbon monoxide (CO) gas.
Although it is possible to sweep the flue
system through this stove once the baffle
plates have been removed (see page 32) it is
recommended that there should be at least
one additional cleaning access point within
either the connecting flue pipe, twin wall
chimney system or where there are bends.
Flexible Flue Liner
Hi-Flame strongly recommend fitting a flue
liner when installing this stove within an
existing chimney for the following reasons:
• A flue liner is a major ‘quantifiable’ component
which provides a consistent flue diameter and
regular inner surface and as such will minimise
interference to the updraught and help improve
it. When back-filled with vermiculite insulation
a liner will keep flue gases as hot as possible
which will help improve the stove’s operation
and minimise the amount of smoke produced.
• An existing chimney could leak smoke,
fumes and potentially dangerous ‘invisible’
carbon monoxide (CO) into other parts of the
building. Condensation or creosote tar,
associated with burning wood, could
eventually seep through the chimney walls,
particularly if they are made of old or porous
brick and / or are jointed with lime mortar,
eventually causing unsightly stains on
decorative coverings.
• Stoves work best with the correct draught.
Pre-1965 chimneys which have been built
for open fires have larger (and often irregular
shaped) voids than those best suited for a
modern stove and this could reduce the
effectiveness of the flue draught by making
the flue too cold and difficult to warm. This
is a particular problem if the chimney breast
is on an outside wall and / or is subject to a
strong prevailing wind.
• Many houses built since 1965 with clay
or concrete chimney liners suffer from these
being poorly installed, either through being
fitted the wrong way up or not receiving an
appropriate application of mortar to make
a complete seal on each of the many joints.
Even though the chimney may not be
particularly old, this could still potentially
allow smoke and fumes or unsightly
condensation stains to leak through.
Chimney Terminal
The existing chimney pot or terminal must be
suitable for stove installation and should not
restrict the smoke and fumes from the stove. It
must provide at least the same outlet area as
the flue pipe. It may be that your existing
chimney terminal has been replaced with a
ventilating terminal if the fireplace has been
closed off at some point. Your installer will be
able to advise you about the appropriate
specification of any new cowl or terminal. A
cowl has the additional advantage of
limiting rain entering the flue system which
could cause the inside of the stove to rust
when it is not being used, particularly during
the long periods outside the heating season. it
will also help to reduce odours from moisture
build-up in the chimney system, through
infrequent burning, as this dries out.

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 (DEFRA) 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 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.
Further information on the requirements
of the Clean Air Act can be found at the
following website:
www.smokecontrol.defra.gov.uk.
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.
The R6 and R6-LS stove has a factory-fitted
combustion air control damper designed to
ensure the correct quantity of combustion
air is always delivered to keep smoke to a
minimum and therefore both models have
been recommended by Defra as suitable for
use in Smoke Control Areas when burning
wood logs.
Never Burn Wet Wood
The recent media coverage of air quality
has increased awareness of this important
issue. Wood fuel marked with the ‘Ready to
Burn’ label shows consumers that logs are dry
and ready for use as wood fuel, and will burn
more efficiently than unseasoned, green wood
and will consequently reduce
their impact on the
quality of our air.
The Woodsure
‘Ready to
Burn’
scheme is
supported
by The
Mayor of
London, Defra,
Hetas and the
Stove Industry Alliance, as well as Hi-Flame.

scheme and the environmental benefits

RECOMMENDED FUEL
CE Standard and other Approvals
Please note that this appliance has been CE
and Ecodesign tested for wood only and the
heat output, emissions and efficiency data, as
well these operating instructions and the
Hi-Flame Warranty only covers the use of wood
in this appliance. They do not cover the use of
other fuels, either alone or mixed with wood
Defra Smoke Exemption
This stove is officially approved by Defra as an
‘exempted appliance’ to allow the burning of
wood in designated UK Smoke Control Areas.
It must, at all times, be operated strictly in
accordance with the instructions to minimise
the amount of smoke produced.
General Guidelines
Only ever use dried, fully seasoned chopped
hardwood logs with a moisture content of
less than 20%. Wood which is well seasoned
makes a distinctive ‘clack’ rather than a dull
‘thud’ when knocked together. It will also
feel much lighter than an unseasoned log.
Other indicators include bark peeling away
and cracking and the log splitting around the
outside edge.
Ideally wood should be seasoned outdoors for
between 18 to 24 months – the harder the
wood then the longer the seasoning. It should
be stacked off the ground with plenty of space
between the logs to allow air movement and
with the top covered to keep rain and snow
out. Fully seasoned wood will give you
approximately 50% more heat output than
the equivalent unseasoned log.
Most types of hardwood, for instance Ash
(generally regarded as the best), Birch, Beech,
Oak and Elm can be used. However, avoid
woods with a high resin content. As a rule
of thumb, the heavier the wood, then the
greater the heat output and the longer burn
time – the time between refills. All of this is
providing it is fully seasoned wood.
Never use wet or unseasoned (green) wood
as this will cause nuisance smoke and a very
disappointing fire. Most importantly, It could
quickly result in the build up of soot and
creosote which the high temperatures of the
stove flue gases could easily ignite and cause
a flue or chimney fire. In addition, burning wet
wood damages local air quality, produces a
less efficient fuel economy and can eventually
clog your flue system and cowl. It will also
reduce the effectiveness of the stove’s Airwash
system thus causing staining and blackening
of the glass.
Wet or unseasoned wood produces
the following poor performance
• Hard to light fires and fires that are
also very difficult to keep burning
• Smoky fires with fewer flames which
are also of a dull or dirty orange colour
• Increased dense grey or blue smoke
from the chimney
• Much shorter burn times with some wood
left unburned at the end
• Low heat output despite the poor flames
• Dirty brown glass and black firebricks
• Excessive and rapid creosote build-up
inside the flue system and chimney
• Unpleasant acrid smoky smells inside
and sometimes outside the house
Manufactured or finished wood products,
such as plywood and chipboard, must also be
strictly avoided because of the high chemical
adhesive content used in their production
which could also leave harmful residue inside
the stove and flue system.
18
Wood logs with a moisture content
of less than 20% is the only fuel that
Hi-Flame recommend for burning in
this stove.

WHEN YOU FIRST LIGHT YOUR STOVE
Use smaller and shorter ‘gentle’ fires the first
five or six times, making these progressively
larger. This will help temper the steel and cast
iron components and avoid any potential
thermal shock which could damage them.
This process will also allow the paintwork to
cure. In fact, you may notice some wisps of
smoke or smell a hint of paint fumes coming
from the stove’s painted surfaces during these
early fires, however this is perfectly normal.
Your smoke alarm or CO detector may also
react to these. Simply ensure that the room
is well ventilated until this settles down. See
page 2 regarding this potential issue.
The hotter you burn the stove the more
intense these fumes will be, which is one
of the reasons that we advise that you use
smaller fires to start with. Every time the stove
reaches a new higher temperature it may still
be possible to detect fumes or smoke until
the paintwork is fully cured. If this persists or
gets any worse beyond the first few fires then
do not use the stove and immediately consult
your stove installer or stove dealer as this may
indicate a potential problem with the
installation. Again, see page 2.
Always allow the stove to fully cool down
between these first fires.
WHEN YOU LIGHT YOUR STOVE
AFTER STANDING IT DOWN
If the stove was correctly prepared for standing
down (see page 39) then simply confirm that
none of the components have deteriorated,
paying particular attention to the vermiculite
panels and baffle as these can be prone to
absorbing condensation. On Initial fires (say
three or four) you may again smell fumes which
will most likely be this condensation (or possibly
condensation within the chimney) simply
drying off. Unless it persists it is not usually
anything to be concerned about.
19
FUELS YOU MUST ALWAYS AVOID
This wood burning stove has been emissions
tested so that when correctly operated it will
have a minimum impact on local air quality
when only burning wood logs with a moisture
content of less than 20%. It has not been
tested for burning mineral fuels including
smokeless coal. Burning other fuels, apart from
logs, is an offence in a Smoke Control Area.
Burning the following materials could also
damage your stove and flue system, and will
render your Hi-Flame Warranty void.
• Never use your stove as an incinerator
Do not burn any household waste such as
magazines, newspapers, cardboard, milk cartons,
vegetable peelings, plastic and rubber etc.
• Never burn other types of wood
During combustion lacquered, painted or
tanalised wood, MDF, plywood, chipboard
and other manufactured wood could develop
substances which may be hazardous to your
health and also damage your stove and flue.
• Never burn petroleum coke
Never burn petroleum coke (aka pet coke) as
this burns at a very high temperature and its
continued use will almost certainly cause
irreparable damage to the stove components
such as the baffle plate and fire fence.
• Never burn bituminous house coal
This has a harmful effect on local air quality.
When burned it produces excessive smoke
and soot with the soot quickly building up
inside the stove’s flueway and flue which
increases the risk of dangerous blockages
and chimney fires. Smoky coal has now been
banned altogether in the Republic of Ireland.
• Never burn flammable liquids
Methylated spirits, petrol or other flammable
liquids should not be used to light the stove
as these could cause an explosion in the
confined spaces of the firechamber.

20
ESSENTIAL SAFETY ADVICE
• Ensure that an approved carbon monoxide
(CO) detector (BS EN50291:2001) is fitted in
the same room as the stove and is regularly
tested. The CO alarm must be installed strictly
in accordance with the manufacturer’s
instructions and permanently fixed so that it
is best placed to monitor the earliest signs of
CO escape. It should be powered by a battery
designed for the working life of the alarm
(usually five years). Hi-Flame recommend
Honeywell or Fire Angel models. Do not be
tempted to buy a cheap alarm as recent
research by the UK consumer organisation
Which? has shown that many of the cheapest
models simply do not work effectively.
• Never operate this stove with the door open
except as directed in these instructions and
when this should be kept to a minimum and
the stove not left unattended.
• External surfaces including the firechamber
door and handle, window, air control, flue
pipes and stove bodywork will become
extremely hot. Always avoid touching these
parts of the stove without proper protection,
such as heat resistant gloves.
• Potentially combustible material or objects
such as soft furnishings should never be left
on or near any of the stove’s hot surfaces. En-
sure that wood supplies and log baskets are
kept at a safe distance from the stove. Never
dry clothes on the stove.
• Never leave children unattended in the
room where your stove is being operated.
Ensure that children are aware of the potential
danger and make sure that they keep clear
of the stove when it is in operation. Where
children, the elderly or the infirm are present,
to prevent accidental contact with the stove,
always use a safety fireguard manufactured in
accordance with BS8423:2002, Fireguards for
use with solid fuel appliances.
WATCH OUT
!
CARBON MONOXIDE KILLS
• For your safety make sure that your stove’s
installation complies with all local Building
Regulations’ ventilation requirements. Low
energy houses have particular requirements
and these should be strictly adhered to.
• Do not use flammable liquids to ignite the
fire. In the confined space of the firechamber
there is a real potential to cause a life
threatening flash flame or explosion.
• Never over-fire the stove. If any external
parts of your stove glow red during operation
then immediate action should be taken to
reduce the supply of air to the firechamber
through the air control which should quickly
limit the intensity of the fire. Do not open the
firechamber door as this will only make the
fire worse. See pages 26 and 27.
• This stove is CE approved and tested to EU
EN13240 standards in Europe by SGS
Nederlands BV. Alterations to its construction
could be potentially dangerous and will render
your Hi-Flame Warranty void.
• Do not use aerosol products in the vicinity
of the stove when it is in use.
• Check and clean the stove’s flueway and
the top of baffle plate regularly to help avoid
potential blockages (see page 32).
• Check the direct external air system’s
outside vent’ grille to ensure there are no
blockages arising from new foliage growth,
wind-blown debris and leaves or snow drifts.
• Sweep your chimney or flue system regularly.
Always use an approved sweep who has
experience of sweeping stove
installations.
