Health And Safety Precautions
Handling
Adequate facilities must be available for loading, unloading and site handling.
Fire Cement
Some types of fire cement are caustic and should not be allowed to come into contact with the skin. In
case of contact, wash immediately with plenty of water.
Asbestos
This stove contains no asbestos. If there is a possibility of disturbing any asbestos in the course of
installation then please seek specialist guidance and use appropriate protective equipment.
Metal Parts
When installing or servicing this stove, care should be taken to avoid the possibility of personal injury.

Installation
Chimney
The chimney height and the position of the chimney terminal should conform to Building Regulations.
Check that the chimney is in good condition, dry, free from cracks and obstructions. The diameter of the
flue should not be less than 150mm and not more than 230mm. If any of these requirements are not met,
the chimney should be lined by a suitable method.
The chimney must be swept before connection to the stove.
Where the chimney is believed to have previously served an open fire installation, it is possible that the
higher flue gas temperature from the stove may loosen deposits that were previously firmly adhered, with
the consequent risk of flue blockage. It is therefore recommended that the chimney be swept a second
time within a month of regular use after installation.
If you have any doubts about the suitability of your chimney, consult your local dealer/stockist.
If there is no existing chimney then either a prefabricated block chimney in accordance with Building
Regulations Approved Document J, or a twin-walled insulated stainless steel flue to BS 4543 can be used.
These chimneys must be fitted in accordance with the manufacturer’s instructions and Building
Regulations.
Flue Draught
A flue draught of minimum 1.2mm to a maximum 2.5mm water gauge is required for satisfactory
appliance performance. The flue draught should be checked under fire at high output. If it exceeds the
recommended maximum, a draught stabiliser must be fitted so that the rate of burning can be controlled
and to prevent over firing. If the reading is less than the recommended minimum than the performance of
the appliance will be compromised.
Connection to the Chimney
An existing fireplace opening can be bricked up or sealed with a register plate. A short length of flue pipe
of a minimum 152mm internal diameter may then be used to connect the stove to the chimney. This flue
pipe should be of 316 grade stainless steel or vitreous enamelled, nominal thickness 1.2mm. Ensure that
the pipe end is no closer than 76mm to the side or rear chimney walls.
Ideally, the old fireplace should be filled in so that there is a smooth streamlined entry into the flue way.
The length of any horizontal run of flue pipe must not exceed 152mm.
It is essential that all connections between the stove and chimney-flue are sealed and made airtight.
Both the chimney and flue pipe must be accessible for cleaning and if ANY parts of the chimney cannot
be reached through the stove (with baffle brick removed), a soot door must be fitted in a suitable position
to enable this to be done.
Air Supply
The room or space containing this appliance needs a permanent, unobstructed air opening of at least 550
mm
2
.
If a draught stabiliser is fitted, the air opening should be at least 1500 mm
2
. Due consideration should be
given to air requirements for any other appliances in the same room or space. Any air opening must be
kept clear from blockage or obstruction.

Material Clearances
The stove can be recessed in a suitable sized fireplace but a permanent free air gap of at least 150mm
must be left around the sides and top and at least 50mm at the back of the stove to obtain maximum heat
output and for access to the rear of the stove.
All non-combustible walls closer than 300mm to the stove should be at least 75mm thick.
In all instances the back wall of the fireplace recess and the hearth should be made of non-combustible
material.
Allow an apron of a least 300mm at the front of the stove and 150mm on either side.
The hearth on which the stove is to be placed should not be less than 125mm thick and should be in
accordance with the current building regulations.
Care should be taken to level the stove using the adjusting screws in the feet.
The appliance shall be installed on a floor with adequate load-bearing capacity. If the existing
construction does not meet this prerequisite, suitable measures (e.g. load distributing plate) should be
taken to achieve it.
MINIMUM DISTANCE TO COMBUSTIBLE MATERIAL
Behind the stove 750mm
At the side of the stove 450mm
There should be NO furniture placed within a distance of 900mm from any surface of the stove.
Note: combustible material refers to any material that will degrade when subjected to heat e.g. plaster.
Note: walls and hearth
are non-combustible
and all dimensions
stated are minimum
125mm
50mm
150 mm
300mm
75mm

Commissioning and Handover
Upon completion of the installation, allow a suitable period of time for any fire cement and mortar to dry
out.
A small fire may then be lit and checked to ensure the smoke and fumes are taken from the stove up the
chimney and emitted safely to atmosphere. Do not run the stove at full output for at least 24 hours.
On completion of the installation and commissioning, ensure that the operating instructions and operating
tools for the stove are left with the customer.
Advise the customer on the correct use of the appliance with the fuels likely to be used on the stove and
warn them to use only the recommended fuels for the stove.
Advise the user on what to do should smoke or fumes be emitted from the stove.
The user should be warned to use a fireguard to BS 6539 in the presence of children, aged and/or infirm
persons.

Primary Air Controls (Open Outwards)
Operating Instructions
This appliance is not suitable for use in a shared flue
This appliance should not be operated with the doors open
Aerosol Sprays
Do not use an aerosol spray on or near the stove when it is alight.
Air Controls
This stove has been designed to burn cleaner and more efficiently than a conventional wood burning
stove. If used correctly this stove will burn far more efficiently than normal with the obvious notable
feature of CLEAN GLASS.
However, for this product to work properly it must be used correctly.
It is essential that the stove has an adequate air supply for combustion and ventilation.
The primary, secondary and tertiary air inlets must be kept clear from obstruction and blockage.
Air Controls
Primary Air
The Sliders in each Door control the Primary air. This provides a
conventional air draught to the bed of the fire. The controls are open
when the Sliders are pushed towards the outside of the Stove.
Secondary Air
Secondary air is controlled via the slider above the doors; it is this
“Airwash” that keeps a clean and uninterrupted view of the fire.
Tertiary Air
Tertiary air aids in good secondary combustion of the fuel and
reducing emissions into the chimney and environment. Adjusting the
cover plate on the back of the Stove can control tertiary air.
Damper Assembly (Optional)
When the damper is set in the open position the chimney draws at full draught, increasing the volume of
airflow through the stove and flue. Shutting the damper restricts the flow, slowing the rate of burning.
Close all other air controls and allow the fire to die down before closing the damper.
Secondary Air Control (Open Right)
Warning!
This Appliance will be hot when in operation and
due care should be taken. The riddling tool may
be used to operate the door handle. Thick gloves
could be used to operate the primary and
second
ary air controls.

Grate
Your Hunter Stove is fitted with a locomotive type grate. So that de-ashing can be carried out cleanly and
easily, it is riddled from the outside of the stove with the doors closed. The grate is designed to burn both
wood and solid fuels.
To burn wood, push the operating tool up and away from you. When
left in this position, air is restricted through the bed of the fire providing
a solid base to build up a bed of ash. Surplus ash can be removed either
by gentle riddling or with a shovel.
It might prove beneficial when burning more reactive fuels to leave the
grate in a “neutral” position, thus directing some under fire air and some
over fire air to the firebed.
Notes on Wood burning
With a full load of wood, the stove will need to be refuelled
approximately once every hour.
Care must be taken that logs do not touch the brick baffle.
Wood burns most efficiently with the primary air sliders in the closed
position and the secondary control open. Moving the secondary control
will control the burn rate of the stove.
Note - primary and secondary air is needed to light the stove, see section entitled ‘Lighting the Stove’
Wood burns best on a bed of ash and it is therefore only necessary to remove surplus ash from the stove
occasionally.
Burn only dry, well-seasoned wood, which should have been cut, split and stacked for at least 12 months,
with free air movement around the sides of the stack to enable it to dry out. Burning wet or unseasoned
wood will create tar deposits in the stove and chimney and will not produce a satisfactory heat output.
Lighting the Stove
We recommend that you have two or three small fires before you operate your stove to its maximum heat
output. This is to allow the paint to cure in steadily and to give a long service life of the paint finish.
During this curing in process you may notice an unpleasant smell. It is non-toxic, but for your comfort we
would suggest that during this period you leave all doors and windows open.
First, load the fire with starting fuel, i.e. paper, dry sticks and/or firelighters. Light the fire at the base
leaving all air controls open. Allow the fuel to reach a steady glow and build the fire up gradually. Once
you have a good fire established across the grate bed, further fuel can be added as required.
Reduced Combustion
In order to reduce the rate of combustion, close the primary air controls and then close the secondary air
slider by moving the handle all the way to the left. If the controls are left in this position, the fire will be
starved of air and die down. If you want to revive the fire it is recommended that the primary air control is
open first, then open the secondary air slider.
Warning!- The stove will remain hot for a considerable time after the fire has been extinguished.

Recommended Fuels
Hunter Stoves recommend that wood logs be burnt in this appliance.
Only authorised smokeless fuels may be used in smoke control areas.
Warning!- Petroleum coke fuels or household waste must not be burnt on this appliance. This appliance
should not be used as an incinerator. No liquid fuels should be burnt on this appliance.
Should any difficulties arise over fuel quality or suitability, consult your local approved coal merchant or:
HETAS Ltd.– Telephone [phone] – www.hetas.co.uk
Solid Fuel Association – Telephone 8 6 – www.solidfuel.co.uk
Safety notes for your guidance
FIRES CAN BE DANGEROUS – Always use a fireguard in the presence of children, the elderly or the
infirm. The fireguard should be manufactured in accordance with BS 6539 – Fireguards for use with
solid fuel appliances.
DO NOT OVERFIRE – it is possible to fire the stove beyond its design capacity, this could damage the
stove, so watch for signs of overfiring – if any part of the stove starts to glow red, the fire is in an overfire
situation and the controls should be adjusted accordingly. Never leave the stove unattended for long
periods without first adjusting the controls to a safe setting – careful air supply control should be
exercised at all times.
WARNING – FUME EMISSION
Properly installed and operated, this appliance will not emit fumes. Occasional fumes from de-ashing and
refuelling may occur. Persistent fume emission must not be tolerated.
If fume emission does persist, then the following immediate action should be taken: -
Open doors and windows to ventilate room.
Let the fire out, or eject and safely dispose of fuel from the appliance.
Check for flue chimney blockage and clean if required.
Do not attempt to re-light the fire until the cause has been identified and corrected.
If necessary, seek professional advice.
Adverse weather – In a small number of installations, occasional local weather conditions (e.g. wind from
a particular direction) may cause downdraught in the flue and cause the stove to emit fumes. In these
circumstances, the stove should not be used. A professional flue installer will be able to advise on
solutions to this problem (e.g. anti-downdraught cowl).
Important! – Do not fit an extractor fan in the same room as this appliance.
IN THE EVENT OF A CHIMNEY FIRE
1. Raise the alarm to let others in the house know.
2. Call the Fire Brigade.
3. Reduce the appliance-burning rate by closing all air controls.
4. Move furniture and rugs away from the fireplace and remove any nearby ornaments.
5. Place a fireguard or spark guard in front of the stove.
6. Feel the chimney breast for signs of excessive heat.
If the wall is becoming hot, move the furniture away. Ensure that the Fire Brigade can gain access to
your roof space in order to check this area for signs of fire spread.

GENERAL MAINTENANCE
NO unauthorised modification of this appliance should be carried out.
This appliance requires regular maintenance by a competent engineer.
Baffle
This should be removed and cleaned at least once a month to prevent any build up of soot or fly ash that
could lead to blocked flue ways and dangerous fume emission.
If the baffle is removed the chimney/flue way can be swept through the appliance (if no damper is fitted
and the flue is connected to the top outlet).
Stove Body
The stove is finished with a heat resistant paint and this can be cleaned with a soft brush. Do not clean
whilst the stove is hot; wait until it has cooled down. The finish can be renovated with Hunter stove
paint.
Glass Panels
Clean the glass panels when cool with a Hunter glass cleaner. Highly abrasive substances should be
avoided as these can scratch the glass and make subsequent cleaning more difficult. Wet logs on heated
glass, a badly aimed poker or heavy slamming of the doors could crack the glass panels. The glass will
not fracture from heat.
Firebricks
In normal use, these can last for many years. It is possible however, to crack them if logs are continually
jammed against them or if they are frequently struck with a poker.
Check periodically for seriously cracked bricks, which can be replaced with new; available from your
dealer.
Door Catch
Should the door catch require adjustment, to maintain the door seal, it is adjustable. By slackening the
internal locking nut and turning the catch bolt one turn towards the door you will achieve a tighter lock
when the door is closed.
Rope
Check the rope around the door and glass. If rope is becoming detached, use Hunter Stoves rope glue to
reattach it. If the rope is in a poor condition, a replacement rope kit may be ordered from the Hunter
Stoves spares range.

Chimney and Flue ways
It is important that the chimney, flue ways and any connecting flue pipe are swept regularly. This means
at least once a year for smokeless fuels and at least twice a year for wood and other fuels. The baffle
brick will need to be removed from its supports in order to sweep the chimney (see assembly
instructions).
Only wire-centred sweeps’ brushes fitted with a guide wheel should be used.
If it is not possible to sweep all parts of the chimney through the appliance, ensure there is adequate
access to cleaning doors.
If the stove is fitted in place of an open fire, then the chimney should be swept one month after
installation to clear any soot falls which may have occurred due to the difference in combustion between
the stove and the open fire.
Seasonal Use - if the appliance has been unused for a long period of time, such as during the spring and
summer months, a competent person should check the chimney for potential obstructions before lighting
the stove.
Gaskets
All gasket used on this appliance are produced from a heat resistant material called Manniglas. The glass
gasket will have to be replaced when a new piece of glass is fitted as the gaskets become brittle after
firing the stove. Over time, you may also find, that the gasket changes colour. This is due to a reduction in
the pigment used in the manufacture of the product and no cause for concern.
Troubleshooting
Fire will not burn
Check that:
1. The air inlet is not obstructed in any way.
2. Chimneys and flue ways are clear.
3. A suitable fuel is being used.
4. There is an adequate air supply into the room.
5. An extractor fan is not fitted in the same room as the stove.
6. Flue draught is above minimum level (see installation instructions).
Fire blazing out of control
Check that:
7. The doors are tightly closed.
8. The air controls are all in the closed position.
9. The Primary air control flap is not wedged in the open position.
10. A suitable fuel is being used.
11. The glass retaining clips are not loose.
12. The door rope seals are in good condition
13. Flue draught is below maximum level (see installation instructions).
