Installation Instructions

These instructions cover the basic principles to ensure satisfactory installation of the stove,
although detail may need slight modification to suit particular local site conditions. In all
cases the installation must comply with current Building Regulations, Local Authority
Byelaws, European and national standards and other specifications or regulations as they
affect the installation of the stove. It should be noted that the Building Regulations
requirements may be met by adopting the relevant recommendations given in British
Standards BS 8303, BS 6461 and BS 7566 as an alternative means to achieve an equivalent
level of performance to that obtained following the guidance given in Approved Document
J.

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.

Important Warning

to emit fumes into the room.

be installed into a chimney that serves any other heating appliance.

not

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 4950 mm2.
If a draught stabiliser is fitted, the air opening should be at least 9150 mm2. Due consideration
should be given to air requirements for any other appliances in the same room or space.

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 hearth should be made of non-combustible material.
If the back wall of the fireplace is closer than 1100mm, to the rear of the stove, it 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 1100mm

At the side of the stove 650mm

There should be NO combustible material (i.e. 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.

Material Clearances

Note: walls and

hearth are non-

combustible and all

dimensions stated

are minimum

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. Ensure to 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.

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

secondary air controls.

Primary Air Controls (Open Outwards)

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.
Tertiary air can be controlled by adjusting the cover plate on
the back of the stove.

Damper Assembly (Optional)

When burning wood, the flue damper assembly may be fitted. 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.

Warning! The flue damper must not be fitted when burning solid mineral fuel.

Multifuel 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 solid mineral fuels place the
operating tool over the riddling spigot and pull
it down 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
firebed 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.

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 solid mineral fuel burning

Solid mineral fuel should be placed in the stove so that there is no more than a 30° incline of the
fuel bed from front to back. It should not be stacked above the level of the rear firebrick as this
may result in damage to the stove.

With a full load of fuel, the stove will need to be refuelled approximately once every 4 hours.

Solid mineral fuel burns most efficiently with the secondary air control in the closed position. The
primary air sliders can then be used to control the burn rate of the stove. For optimum
performance when burning only solid-mineral fuel, it may also be beneficial to close the tertiary
air cover plate on the back 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 sliders 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!

Air passing through the firebed 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.

-

We cannot stress firmly enough how important it is to empty the ashpan regularly.

Notes on Wood burning

With a full load of wood, the stove will need to be refuelled approximately once every 1.5 hours.

Wood can be stacked higher in the stove than solid mineral fuel but 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 in the mode chosen, either
wood or solid mineral fuel.

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.

Extended burning

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 primary and secondary air
controls, the exact setting required will depend on the fuel used and the chimney draw so some
practice may be necessary. It may also be necessary to adjust the tertiary air cover plate on the back of
the stove. 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.

Reduced Combustion

In order to reduce the combustion of the fire to a minimum, close the primary air sliders, 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 receive the minimum of air and will 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

Anthracite is an approved natural smokeless fuel (not processed) and therefore can vary greatly in
quality and performance. It generally requires excellent air supply and above average fire-bed
temperatures to maintain maximum performance and with experience we would suggest that it is
used in conjunction with other approved manufactured smokeless fuels as per the HETAS
approved list.

HETAS Ltd. approve the following fuels in closed appliances:-

Coalite

Coalite Nuts

Blazebrite

Homefire

Homefire Ovals

Phurnacite

Mixed Nuts

Approval does not cover the use of other fuels either alone or mixed with the suitable fuels
listed above, nor does it cover instructions for the use of other fuels. 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:

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 de­ashing and refuelling may occur. Persistent fume emission must not be tolerated.

If fume emission does persist, then the following immediate action should be taken: -

1. Open doors and windows to ventilate room.

2. Let the fire out, or eject and safely dispose of fuel from the appliance.

3. Check for flue chimney blockage and clean if required.

4. Do not attempt to re-light the fire until the cause has been identified and corrected.

If necessary, seek professional advice.

Important! – Do not fit an extractor fan in the same room as this appliance.

IN THE EVENT OF A CHIMNEY FIRE

• Raise the alarm to let others in the house know.

• Call the Fire Brigade.

•

• Move furniture and rugs away from the fireplace and remove any nearby ornaments.

• Place a fireguard or spark guard in front of the stove.

•

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.

Reduce the appliance-burning rate by closing all air controls.

Feel the chimney breast for signs of excessive heat.

GENERAL MAINTENANCE

NO unauthorised modification of this appliance should be carried out.

This appliance requires regular maintenance by a competent engineer.

Brick 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 brick is removed the chimney/flue way can be swept through the appliance.

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 locking nut and turning the door handle one turn clockwise, 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.

Gaskets

All gasket used on this appliance are produced from a heat resistant material called Manniglas.
Over time you may find that the gasket changes colour. This is due to a reduction in the pigment
used in the manufacture of the product, and is no cause for concern.

Troubleshooting
