Pre-Installation Requirements
PLEASE CHECK THE FOLLOWING:
Any existing chimney/flue system must be confirmed as suitable for this appliance as defined in Building Regulations
Document J. It must be swept and inspected, by a competent person (see notes), to confirm that is structurally
sound and free from cracks and obstructions.
The diameter of the Flue should not be less than Ø125mm (Hawk 4) and Ø150mm (Herald 6, 8 and 14) and not more
than Ø200mm. Do not connect to systems that have large voids or spaces. If any of these requirements are not met,
the chimney should be lined by a suitable method.
If the chimney is suspected of previously serving an open fire it must be swept again, within a month of regular use,
to clear any soot that may have been dislodged due to the variation in combustion levels and higher flue gas
temperature levels. The chimney/flue system exit must comply with Building Regulations Document J. The minimum
height and should terminate in accordance with Table 1.
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
minimum 125mm (Hawk 4/4D) or 150mm (Herald 6, 8/14) internal diameter may then be used to connect the stove
to the chimney. This flue pipe should be made of 316 grade stainless steel or vitreous enamelled steel, nominal
thickness 1.2mm. Ensure that the pipe end is no closer than 76mm to the chimney walls. The length of any
horizontal run of flue pipe must not exceed 125mm (Hawk 4/4D) or 150mm (Herald 6, 8/14). It is essential that all
connections between the stove and chimney-flue are sealed and made airtight.
Make provision to access the chimney/flue system for cleaning and the removal of debris. 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 BS4543 can be used. These chimneys must be fitted in accordance
with the manufacturer’s instructions and Building Regulations. New masonry and flue block chimneys must meet the
requirements of Building Regulations Document J. Any connecting flue pipe systems must also meet these
regulations.
Please check the suitability of the fireplace and/or surround for use with this appliance before installing it. If you
have any doubts about the suitability of your chimney, consult your local Dealer/Stockist or Installation Engineer.
Both the chimney and flue pipe must be accessible for cleaning and if ANY part of the chimney cannot be reached
through the stove (with baffle removed), a soot door must be fitted in a suitable position.

Appliance Check
Please check that all components are correctly assembled and working correctly.
Ensure the Air Controls are working correctly.
Hunter Stoves Group recommend that you carry out a smoke draw test to check the soundness of the chimney/flue
system and seals:
Place a Smoke Pellet in the centre of the Grate, ensure that all of the Air Controls are fully open and close the Door.
The smoke should now be drawn up the chimney and you should be able to see it exit from the chimney/flue
terminal.
We recommend that you do this test with all of the windows and doors, to the room where the appliance is fitted,
closed.
If there any adjoining room(s) that have an Extractor Fan fitted, open the adjoining door to ensure that the
chimney/flue system is not compromised when the fan is operating. If there is a ceiling fan fitted in the room, please
operate it and ensure that it does not affect the operation of the chimney/flue system.
If any of these tests fail, please re-check the suitability of the chimney/flue system together with the ventilation.

The stove can be recessed in a suitable sized fireplace but a
permanent free air gap of at least 150mm on top and
50mm at the sides (although we recommend 150mm for
the sides of the stove to obtain maximum heat output and
for access to the rear of the stove.)
The hearth should extend at least 300 mm from the front
of the stove. The stove should stand wholly above a solid,
non-combustible hearth, at least 125 mm thick (this may
include the thickness of a solid floor and a non-combustible
decorative hearth).

15
A small fire can now be lit and allow the appliance to heat up slowly ensuring that no products of combustion enter
into the room.
Carry out a spillage test using a smoke match around the door opening. If there is excessive spillage, please allow
the appliance to cool and then re-check the chimney/flue system and ventilation.
Do not run the stove at full output for at least 24 hours.
Upon completion, allow a suitable period of time for any fire cement and mortar to dry out. Please instruct the user
on the safe operation of this appliance, how the controls work and basic maintenance requirements.
Ensure that the operating instructions and appliance tools are left with the customer and the check lists have been
filled out correctly.
Please 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 8423 in the presence of children, aged and/or infirm persons.
Hunter Stoves Group also recommend that a CO alarm is fitted into the room where the appliance is located.
Flue Draught
If the draught 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, then the performance of the appliance will be compromised.
The flue draught should be checked under fire at high output with windows and doors closed. To take the reading
remove one of the coach bolts in the flue collar and put the probe in the hole.
Minimum Draught –1.2mm Water Gauge
Maximum Draught –2.5mm Water Gauge
Operating Instructions
Read the ‘General Guidance’ Section at the start of these instructions before operating your stove for the first
time.
Allow sufficient clearance between the stove and pictures, plasma screen televisions or ornaments etc., as these
could be damaged and could potentially create a fire hazard (For more information read the ‘Material Clearance’
section of these installation instructions).
WARNING –This appliance will be hot when in operation and due care should be taken. The supplied operating
tool or gloves may be used to open the door and operate the air controls.
Please Note
Your Building Insurance Company may require you to inform them of this new installation and that the work has
been carried out correctly. Please check your policy to ensure that it is still valid when this installation is complete.
Using The Appliance For The First Time
When being heated up for the first time, smells and fumes are often produced. This is a normal chemical process
that allows the specialist heat resistant paint to cure and harden.
SAFETY ADVICE
During the first operation it is highly likely that fumes and smells maybe produced as part of the
normal heat resistant paint curing process, much like a domestic oven. Therefore, good ventilation
during this process is of utmost importance. We recommend that pregnant women, allergic
persons and small children as well as domestic animals, especially birds, should not unnecessarily
stay in subjected areas.

16
Please arrange for good ventilation of the room. Open windows and doors and if necessary, use a ventilator for fast
interchange of air. Heat up to operation temperature for at least one hour. If maximum temperature is not
achieved after heating up, release of odour may appear later.
Aerosols
Do not use an aerosol spray on or near the stove when it is alight.
Air Control
This stove has been designed to burn far more efficiently than a traditional stove if used correctly, with the obvious
notable feature of CLEAN GLASS.
It is essential that the stove has an adequate air supply for combustion and ventilation.
The primary and secondary air inlets must be kept clear from obstruction and blockage.
Primary Air
This provides a conventional air draught to the bed of the fire.
Hawk 4/4D only.
Primary air is controlled
via the spinner in the door.
Turn the spinner to the right
to open and to the left to close.
Herald 6/8/14
Primary air is controlled
via the slider(s) in the door(s).
To increase air, move the slider
to the right. This provides a
conventional air draught to
the bed of the fire.
Secondary Air (All)
Secondary air is controlled via
the slider above the door(s);
it is this “Airwash” that keeps
a clean and uninterrupted view
of the fire. The amount of air
can be increased by moving the
slider to the right.
Tertiary Air (All)
Tertiary air aids in good secondary combustion of the fuel and reducing emissions into the chimney and
environment.
Tertiary air can be controlled by adjusting the cover plates on the base of the stove.
Warning! –This Appliance will be hot when in operation and due care should be taken.
We advise that suitable gloves are used when operating the air control, and when opening the door.

Lighting the Stove
To light the stove, open the primary and secondary air controls fully.
Light one or two firelighters placed centrally on the grate, allowing the flames to become established before placing
several pieces of small dry kindling in a criss-cross fashion above the firelighters, taking care not to smother the fire.
Close the stove door. Once the kindling is well alight open the door and build the fire by gradually adding slightly
larger pieces of wood, closing the door afterwards.
Once you have a good fire established across the grate bed, further fuel can be added as required and the air
controls set to the correct position.
Should the fire fail to light correctly open the door and use a poker to spread the fuel across the grate. Close the
door and allow the fuel and stove to cool before attempting to relight the fire.
N.B. Leaving the air controls in the closed position, adding too much fuel or using wood that is wet or too large will
prevent the fire from establishing correctly and may result in smoke emission from the stove.
Locomotive Grate
Grate Operation & Burning Wood
Your stoves are 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.
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
fire bed.
Grate Operation & Burnint Solid Mineral Fuels
To burn solid mineral fuels, place the operating tool over the riddling spigot and pull it towards you. When left in
that position, air is directed under and up through the slots in the firebed, giving the optimum conditions for burning
solid fuels.
It is important that the riddling tool is used to remove the ash to ensure airflow through the fire bed and allow the
fire to burn over the entire area of the grate. The ashpan should be emptied at least daily and ash should never be
allowed to build up over a period of time as this will result in damage to the fire bars. The flat end of the riddling tool
can be used to carry the ashpan.
Loading The Appliance (Solid Mineral Fuel)
It should not be stacked close to the turbo bar as this may result in damage to the bar. With a full load of fuel, the
stove will need to be refuelled approximately once every 2 hours.
Air Controls (Solid Mineral Fuel)
Solid mineral fuel burns most efficiently with the secondary air control in the closed position. The primary valve
lever can then be used to control the burn rate of the stove. Always de-ash before refuelling and do not let the ash
build up to the underside of the grate bars. Solid mineral fuel produces ash, which if allowed to build up will stifle
the airflow through the Primary air valve cavity and grate. This will eventually cause the fire to die. With some solid
mineral fuels, a residue of burnt fuel or clinker will accumulate on the grate, allow the fire to go out periodically to
remove this.
IMPORTANT!
We cannot stress firmly enough how important it is to empty the ashpan regularly. Air passing through the fire bed
cools the grate bars. Distortion or burning out the grate bars is nearly always caused by ash being allowed to build up
to the underside of the grate.

18
Extended Burning (Solid Mineral Fuel)
The stove can be banked up for extended burning. When burning solid fuel, empty the ashpan. Open air controls and
let the fire burn brightly for a short period. Refuel and close both air controls, the exact setting required will depend
on the fuel used and the chimney draw so some practice may be necessary.
To revive the fire, open the air controls until the fire is burning brightly de-ash if necessary and refuel. Set air
controls as required.
Never leave the stove unattended until you are certain that the flames are fully established.
Should the fire fail to light correctly open the door and use a poker to spread the fuel across the bottom of the
firebox. Close the door and allow the fuel and stove to cool before attempting to relight the fire.
Notes on Woodburning
With a full load of wood, the stove will need to be refuelled approximately once every hour. Wood can be stacked in
the stove, but care must be taken that logs do not touch the baffle. Overloading the stove can cause excess smoke
to be emitted. Wood burns most efficiently with the secondary air valve lever in the open position and the primary
control closed. 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 most efficiently on a bed of ash and it is therefore only necessary to remove surplus ash from the stove
occasionally.
If there is insufficient burning material in the fire bed to light a new fuel charge, excessive smoke emission can occur.
Refuelling must be carried out with a sufficient quantity of glowing embers and ash, so that the new fuel charge will
ignite quickly. If there are too few
embers, add some kindling to prevent excessive smoke.
Maximum Log Length: See Technical Data
Ensure your logs are well seasoned with a moisture content of less than 20%
Reduced Combustion
In order to shut down the stove, close the primary control, 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 will die down.
If you want to revive the fire it is recommended that the primary air control is open first, and then open the
secondary air slider.
Warning! - The stove will remain hot for a considerable time after the fire has been extinguished.
Refuelling
Refuelling must be carried out with a sufficient quantity of glowing embers and ash, so that the new fuel charge will
ignite quickly. If there are too few embers, add some kindling to prevent excessive fuel. The air controls should not
need adjusting while refuelling.
(When refuelling it is important to have a damper in the open position if you have one.)
Recommended Fuels
Hunter Stoves Group recommend that only wood logs with a moisture content of less than 20% and anthracite or a
manufactured briquette smokeless fuel which is suitable for closed door appliances are used on this appliance.
Burning wet or unseasoned wood will create excess smoke emissions, tar deposits in the stove and chimney and will
not produce a satisfactory heat output.
Only authorised fuels may be used in UK smoke control areas.
A list of authorised fuels can be found at

WARNING - DO NOT BURN BITUMINOUS COAL, PETRO-COKE, OTHER PETROLEUM BASED FUELS OR TREATED
WOOD SUCH AS PALLETS AS THIS WILL INVALIDATE THE PRODUCT WARRANTY. HOUSEHOLD WASTE MUST NOT
BE BURNT ON THIS APPLIANCE.

Maintenance And Servicing
WARNING!
NO unauthorised modification of this appliance should be carried out.
IMPORTANT!
In order to ensure continued compliance with current Building Regulations and Local Authority Byelaws, this
appliance requires regular maintenance by a competent person. N.B. Refer to the ‘Removing Internal Components’
section of the installation instructions for details on how to remove each component.
Periods Of Prolonged Non-Use
If the stove is to be left unused for a prolonged period, then it should be given a thorough clean to remove ash and
unburned fuel residues. To enable a good flow of air through the appliance to reduce condensation and subsequent
damage, leave the air controls fully open. If the appliance has been unused for a long period, such as during the
spring and summer months, a competent person should check the chimney for potential obstructions before lighting
the stove i.e. get the chimney swept before the start of the heating season?
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.
Stove Body
Painted Finish - The stove is finished with a heat resistant paint and this can be cleaned with a dry soft brush or dry
microfiber cloth. Do not clean whilst the stove is hot. At no point should any water or other cleaning products be
used on the stove. The finish can be renovated with Hunter Stoves paint.
Glass Panel
Clean the glass panel when cool with a propriety 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. Should you
need to replace a glass panel please ensure you purchase a new Gasket at the same time. Please check periodically
that the glass clips and screws have not become loose. They should only be finger tight to allow for the expansion
and contraction of the glass.
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.
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 or our spares website www.hunterstoves.co.uk.
Door Catch
The door catch may require adjustment to maintain the door seal. 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. If rope is becoming detached, use rope glue to reattach it. If the rope is in a poor
condition, a replacement rope kit may be ordered from the Hunter Stoves Group spares range.

20
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 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.
Annual Service
Hunter Stoves Group recommend that this appliance is serviced annually, preferably prior to the start of the heating
season, thus avoiding any delay in receiving replacement components, should you need them.
If you feel unable to undertake this task, Hunter Stoves recommend that you contact the installation engineer for
advice.
Remove all the internal components:
Riddling Bars, Cam Bar, Catch Bar, Ashpan, Side Plates and Baffle. Clean them with a soft brush and inspect them for
damage.
Sweep the chimney/flue system if necessary.
Clean down the internal surfaces of the appliance using a scraper or wire brush.
Inspect these surfaces for damage/corrosion.
If corrosion or damage is found, we advise that you consult with your installer about rectification/repair.
Brush out or vacuum the inside of the appliance and re-fit the internal components.
Inspect the Glass and Gasket. Clean the Glass with a non-abrasive cleaner if required. If the Gasket is torn or
damaged, we recommend that is replaced to ensure that no products of combustion enters the room when the
appliance is used.
Painted Finish - Brush down the outer surface with a dry soft brush or dry microfiber cloth only and touch up the
paint if necessary.
Burn the appliance at a low rate, after maintenance, to allow any new seals, paint or glue cure properly.
The appliance may emit unpleasant odours during this process, please ensure the room is well ventilated.
The paint can be ordered through our website www.hunterstoves.co.uk.
