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
This stove must not be installed into a chimney that serves any other heating appliance.
There must not be an extractor fan fitted in the same room as the stove as this can cause the stove
to emit fumes into the room.

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 mm
2
.
If a draught stabiliser is fitted, the air opening should be at least 9150 mm
2
. 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.

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.

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
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
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.
