IMPORTANT
READ BEFORE USE
We use Stove Bright® High Temperature Paint on all of our stoves and it is important that the paint
is cured properly during the rst burn of the stove. This is done to ensure the paint nish will be able
to withstand the high temperatures needed. Curing is done by following the instructions below. If this
process is not done properly during the rst burn of your stove, you may experience issues with the
paint peeling over time, especially when the stove is operated at a high heat.
Set / Cure the paint
For wood burning, follow these guidelines:
1. Build a small kindling re to start. The kindling re should be kept burning for 10 to 15
minutes.
2. Add fuel to build a medium size re to bring the stove surface temperature to about 450°F.
3. The medium size re should be kept burning for about 60 minutes.
4. For the nal stage of curing, add fuel to this re to make it a very hot re (surface temperature
above 600°F) and keep it at this level for about 60 minutes.
Once this initial process has been completed, the paint will be properly cured and you can operate
your stove normally according to the instructions provided in this manual. If any peeling of the paint
occurs on your stove this will only be as a result of improper curing or misuse of the stove such as
over fuelling or running the stove too hot. Therefore any peeling is not covered by your warranty.
NOTE: During the nal higher temperature burn phase there may be some visible smoke near the
stove surface. There may also be an unpleasant odour. To mitigate this effect, ventilate the room
with open windows and doors to provide airow.
HEALTH WARNING: The smoke from the curing process displaces oxygen. Small children, the
elderly and persons with existing breathing problems should vacate the area during the hot burn to
avoid the discomfort of lost oxygen. The smoke is primarily Carbon Dioxide, and therefore non-toxic
but uncomfortable.
Trouble Shooting: Paint Curing
Take care to build slowly to the medium temperature re. Building a hot re immediately will “shock”
the paint and cause it to release from the surface. The only remedy to this problem is to remove the
paint, prepare the surface for repainting, and repaint. To avoid problems during the curing process,
do not touch the surface with anything until the paint is fully cured.

Important To Remember
Installation By Authorised Technician
This manual contains instructions on how the stoves must be assembled, maintained and installed. To ensure the
function and safety of the stove, we recommend that the installation must be carried out by an authorised technician.
Contact one of our dealers to nd a suitable tter.
Structural Support
Check that the wood joists are strong enough to bear the weight of the stove and chimney. The stove and chimney can
usually be placed on a normal wooden joist in a single occupancy house, if the total weight does not exceed 400kg.
Building Permission
Before installing a stove or erecting a chimney, it is necessary for you to make an application for building permission to
your local authority. Ask your local authority for advice regarding building regulations and the application.
Hearth Plate
Due to the risk of embers falling out, a ammable oor must be protected by a hearth plate. It must extend 300mm in
front of the stove and 300mm on each side of the stove, or have a 200mm extension on each side of the opening. The
hearth plate can consist of natural stone, concrete, metal plate or glass.

Operating Instructions
NOTE: All multi-fuelled stoves must be installed by an approved installer, and all
necessary checks described in the Installation Instructions need to be carried out.
Only use the recommended fuels detailed below.
Recommended Fuels
The Zeta stoves are Multi-Fuel appliances, meaning they can burn a number of different
fuels, however you must ensure that you follow the instructions specic to your chosen type
of fuel and that your chimney is suitable for all the types of fuel you will use.
Wood
The wood you use to burn in this stove should only be dry and well seasoned. To prepare the
wood for burning ensure it is cut, split and then left to season in a dry, well ventilated area for
at least one year before burning. The ideal types of wood for this stove are hard woods such
as Ash, Beech or Oak. We recommend that all wood has a moisture content of less than 20%.
The rebox should have a bed of ash at the base for the wood to be placed on. The use of
unseasoned wood in this appliance can result in heavy tar deposits in the stove, on the glass
and within the chimney. Also unseasoned wood will produce lower outputs from the re.
Peat
Cut peat must be dried before using in the stove in order to reduce the amount of tar deposits
produced. You should burn Peat in the same way as wood fuel, on a bed of ash at the base
of the stove.
Smokeless Fuel (Solid Mineral Fuels)
A variety of smokeless fuels may be used in this stove, however you must check the necessary
precautions for each specic fuel to prevent damage. These fuels include:
• Ancit
• Anthracite Large Nuts
• Centurion
• Extracite
• Homere
• Maxibrite
• Phurnacite
Only smokeless fuels may be burnt in smoke control areas. Petroleum Coke is not suitable
for use on this appliance, it’s use will void your warranty.
There are a few additional points to consider when lighting smokeless fuel res, please refer
to the ‘Burning solid mineral fuels’ section on the next page.

Setting The Air Control Management
The following is a recommendation only for maximum efciency.
When burning wood only or solid mineral fuels (smokeless fuels) the following settings are
recommendations only as it is all dependent on the moisture content of the material to be
burnt.
So if the moisture content is above 16 to 20% which is the recommended level in any of
these products you may well need to make adjustments to get the optimum burn efciency
out of this stove. So the following is a guide only to the position of the primary secondary and
tertiary air controls.
Please note that wood burns from the top of the re box down so more control is gained from
the secondary and tertiary slider control bar. These operate the clean glass air wash system
which assists in helping to prevent the glass blackening up and the Eco-Cleanburn at the
rear of the re box which helps to insure that all of the gases given off from the wood and
solid mineral fuels are fully burnt prior to being exhausted up the chimney, therefore giving
maximum heat output and efciency to the stove.
As you open and close the single slider for the clean glass air wash (secondary) and the Eco-
Cleanburn (tertiary) there is a balancing valve (which you never need to touch) tted into the
rear of the stove that automatically manages the volume of air being fed to each of the outlet
air controls so the optimum airow is delivered to the clean glass air wash down the front of
the glass and the Eco-Cleanburn afterburn at the rear of the re box.
However, solid mineral fuels burn from the bottom up so you require air ow from the primary
air knob on the door and less from the secondary and tertiary control.
Please refer to the table below as a guide only to the position of the 2 air controllers.

Lighting The Stove
When lighting the stove for the rst time your appliance may give off an odour, this is caused
by the paint inside the stove reacting to the heat. This is completely normal and will cease
after a short time, however the room should be kept well ventilated while this is still occurring.
The stove door handle is located on the bottom right of the door, pull the handle (see Fig. 1)
out to open the door and insert your fuel. When closing the door be careful not to slam it shut
to avoid damage to the closing mechanism or glass, also when opening the door be careful
of any pieces of fuel or embers that may be resting on the door. To begin you should only
light a small re and allow it to burn slowly for at least two hours. This initial re will evaporate
any residual moisture contained within the vermiculite bricks, allowing you to use the re as
normal from then onwards.
When burning wood or peat ensure that there is a layer of ash at the base of the rebox
to prevent overheating and damage to the base. If there is no ash available when you rst
light the stove, you can add a layer of sand approximately 13mm (1/2 inch) thick to the base
instead.
Lighting the stove
To start the re you can use dry kindling wood with
either paper or re lighters. Place the paper or re
lighters along with the kindling on the base of the
rebox and cover with approximately 50mm of fuel.
Light the paper or re lighters to start the re, then
ensure the primary air vent is open on the door
(approx. 4 full turns so you can see a 5mm gap
between the knob and the door. Do not open further
than this. See Fig. 1) of the stove before closing it
and pull the Air Wash control towards you to open
the rear Air Wash vent (see Fig. 2b). Allow the re to
be fully ignited before adjusting the air vents to the
preferred position, as detailed on page 6. Once fully
lit, you can close down the primary air knob.
Always take care when touching any part of the stove to prevent burning
yourself and we always advise using an appropriate glove when adjusting the
air vent, opening/closing the re door and when refuelling. Please note that
the stove can remain hot for long periods after the re has been extinguished.
When relighting the stove leave the ash from previous res on the base of the rebox, however
some may be removed if the build up starts to block the front grill. You should always ensure
there is enough ash at the bottom of the rebox to protect the stove’s base before lighting a
re.
Burning smokeless fuels
When loading the re with smokeless fuels it is advised not to put all the required fuel in at
once, load in two stages to ensure that the re will not be smothered and wait between each
stage for the ames to grow before adding the remaining fuel. Certain fuels may produce
more soot deposits than others, therefore it is essential for you to regularly clean the throat
plates to avoid build up. When relighting a smokeless fuel re ensure you have cleared the
grate and emptied the ashpan before starting a new re.

Operating The Stove With The Door Open
This stove should not be operated with the door open, we do not recommend this. This stove
is designed to be operated with the door closed as this gives improved efciency and air
ows. Certain fuels such as wood and peat will burn better this way but it is vitally important
that you do not leave the re unattended with the door open at any time. Always keep
the door closed and the handle in the locked position.
Controlling The Stove
The primary air vent knob on the front of the
stove door and the secondary and tertiary slider
bars under the door (see Fig. 2) control the rate
of burning and in turn the heat output. The clean
air wash is known as the secondary air control
and the Eco-Cleanburn is known as the tertiary.
These are fully controlled by the slider bar in the
centre of the stove. The front primary air control
knob should only be left fully open when lighting
or when rapid burning is needed. If the knob is
left open for long periods then over-ring may
occur. Once lit we recommend the front primary
air knob be left slightly open (1-2mm only), and
adjust accordingly to control the re. The knob
should be turned to the left to open the vent, and
to the right to close the vent (see Fig. 1). The front primary control is fully open when the gap
between the vent holes and the back of the knob is 5mm, opening further than this point will
not increase airow.
The door handle, two control bars (air wash and riddle plate) and primary knob will
heat up when the re is lit and running. But when you need to touch them to adjust
or reload the re you must wear gloves. Therefore to avoid injury please wear
appropriate hand protection when touching any part of the stove as the body,
the glass and the primary air knob can get very hot.
Refuelling
Keep the rebox well lled to maintain the re
but for safety reasons it is important not to overll
the stove, your fuel must not be spilling over the
top of the front grill or touching the door or glass
panel. Doing this could cause the re to spill out
when opening the door. Overlling can also cause
the glass to black up. Do not ll past the ll line,
which is 25mm below the tertiary plate as this may
restrict airow to the Eco-Cleanburn bar. (see Fig.
3).
When adding fuel ensure that the appropriate
protection is worn such as a heat resistant glove and tools such as re poker, tong or shovel
are used.

Cleaning & Maintenance
Our stoves are nished with high temperature resistant paint which can withstand the
temperatures expected in normal use. You may clean the stove with a damp lint-free cloth,
but ensure the stove is completely cold throughout before doing so.
To clean the glass on the door, again use a damp lint-free cloth to clean and ensuring that
you wipe with a dry cloth afterwards. Do not use any chemicals to clean the glass, this will
cause permanent damage to the glass. You may get deposits on the glass after the re has
run, most of these will burn off if you run the re again at a fast rate for a few minutes. Do not
use abrasive cloths on the glass or paintwork as these can cause scratching and permanent
damage to the stove.
Ash Clearance
With wood or peat res you should allow some
build up of ash at the base of the rebox, however
it is necessary to remove some ash once the
build up gets too much. This will only be needed
when the build up starts to restrict the airow by
blocking the front grill. Burning smokeless fuels
will require the ashpan to be emptied regularly, it
is very important to do this as this ash must not be
allowed to overow over the grate.
This model has a Remote Riddle Plate Bar located
under the left side of the door, pulling this bar
will rotate the grills allowing excess ash to drop
through to the ashpan below the rebox (see Fig.
4). Be sure not to completely empty the base
of ash.
It is very important that all ash is cool before attempting to remove it from either the base or
the ashpan. We advise emptying the cold ash into a bin liner and sealing it before disposing.
Throat, Baffle Plate & Flueway Cleaning
It is very important that the throat, bafe plates and the ueway are kept clean and obstruction
free, failure to do so could result in dangerous emissions not escaping correctly. These fumes
can pose a serious health risk to occupants therefore it is necessary to clean both the throat
and bafe plates and the ueways at least weekly, or more frequently if needed.
To clean the throat and bafe plates, rst remove the side bricks to enable you to easily
remove the throat plate. To access the ueway, remove the two saddle clips to release the
upper bre board that covers the ueway. Any build up of soot should then be swept off the
plate down onto the re. Ret parts in reverse order when cleaning is nished, for more detail
please refer to page 18.
Removing The Primary Air Knob
If you wish to remove the primary knob completely from the stove you just have to keep
turning the knob in an anti clockwise direction. The knob has 100mm of threaded bar tted to
Fig. 4
Remote
Riddle
Plate Bar

the rear of it, so you just unscrew it approximately 100mm out from the front of the door and
then it can just be removed. When unscrewing it you need to support it so it does not drop on
the hearth and also make sure none of the threads are damaged as you remove it.
For normal operation this primary knob only needs to be opened four turns so there is a
obvious gap of approximately 5mm from the front of the door to the back of the knob, at this
point the maximum airow is able to access the stove. You do not need to open (unscrew) it
any further than that as you will not be getting any more air into the re box.
Please note the primary air knob can become very hot when the stove is burning do not
attempt to remove the primary air knob unless the whole stove is in a cold state.
Chimney Sweeping
Your chimney should ideally be swept at least twice a year. Depending on your installation
you may be able to sweep your chimney through your appliance, if not your installer would
have inserted a soot door to access the chimney once the stove has been moved clear. When
sweeping through your appliance you will rst need to remove the throat plate, upper bre
board and front grill from the stove.
Your installer will advise on what tools you will need to sweep your chimney. After sweeping
you must ensure that all ueways are clear and no soot deposits have collected to form a
blockage particularly on any horizontal surfaces.
Combustion Air Supply
In order for the stove to work efciently and safely there needs to be an adequate supply of
combustion air in the room where the stove is installed. This is necessary where the room
is double glazed or where a ue draught stabiliser is operating in the room where the stove
has been installed. Provision of air to the stove must be in accordance with current Building
Regulations Approved Document J. An open window is not appropriate. Any air inlets must
be positioned in such a way as they cannot be blocked.
Seasonal Use
If the stove is not used for a long period of time (e.g. Summer) then it must be thoroughly
cleaned with ash and unburned fuel being removed. It is important to leave air controls fully
open when the stove is not being used, this will prevent build-up of condensation / corrosion.
It is important that the ue connections, any bafes, throat plate and chimney are swept clean
prior to lighting again.
Adverse Weather Conditions
If, due to adverse weather conditions, your stove does not operate properly and smoke is
emitted into the room, DO NOT treat this as a minor problem. Smoke indicates that Carbon
Monoxide (CO) is entering the room. Should this happen, turn your stove controls to their
minimum setting (still allowing the re to burn) open windows to ventilate the room. DO NOT
close the windows before the re has burned out.
The smoke entering the room is probably due to a poor draught or a blocked ue. It is advisable
to have the ue pressure checked. The minimum operating pressure for a ue is 12 Pascals.

Troubleshooting
Fire will not burn
Check that:
• the air inlets are obstruction free
• chimneys and ueways are clear.
• you are using a suitable fuel.
• an adequate air supply is entering the room.
• an extractor fan is not tted in the same room as the stove.
• the chimney has a sufcient draw. A draught reading of at least 2.5mm water gauge
should be seen (once the chimney is warm).
Door glass blacks up
Because chimneys differ greatly the best draught settings will take a few trials to gure out,
but the following tips should help:
• When re-fuelling place the fuel towards the back of the rebox, keeping it as possible
from the front grill and avoid over lling.
• The primary air vent on the door may be kept slightly open to assist in keeping the
glass clean or open up the secondary and tertiary slider bar further.
• Unseasoned wood will cause more deposits on the glass if the moisture level is more
than 20%.
Bear in mind it tends to be more difcult to keep the glass panel clean if you’re running the
stove very slowly for a long period of time. If blackening of the glass still occurs ensure that
all ue connections are well sealed with re cement, as this can decay over a long period of
time and may need resealing. Also the chimney draw needs to be sufcient and not affected
by down-draught.
When certain smokeless fuels you may notice some blackening of the glass below the
grill level, this is to be expected and shouldn’t obscure your view of the re or affect the
performance of the stove.
Fume emission
IMPORTANT: If this appliance is properly installed and operated it will not emit fumes.
Occasional fumes when de-ashing or re-fuelling are to be expected, but fumes during normal
use are NOT usual. Persistent fume emission can be very dangerous and should NOT be
ignored. If you notice persistent fume emission you should immediately:
• Open all doors and windows in order to ventilate the room.
• Let the re go out and safely dispose of the remaining fuel from the appliance.
• Check for any blockage to the ue or chimney and clean if required.
• DO NOT attempt to re-light the re until the cause of the fumes has been identied
and resolved. Seek professional advice if necessary.
The most likely cause of fume emission would be due to ue or chimney blockages. For your
own safety it is vital that you regularly check and clean your ue and chimney.
Operating Instructions

Fire blazing out of control
Check that:
• the door is tightly closed, the handle is locked and the seal is intact.
• the air vents are closed fully (primary, secondary and tertiary).
• a suitable and well prepared fuel is being used.
Chimney res
If your chimney is properly installed and regularly swept, chimney res should not occur.
However, if a chimney re does occur the rst step would be to ensure the door is tightly
closed and the air vents are fully shut (primary, secondary and tertiary), doing this should
cause the chimney re to extinguish itself. After this you must keep the door and air vents
closed until the stove’s re has gone out completely to prevent the chimney re reigniting.
Once this has happened and the stove has cooled you must then clean the chimney and
ueways to prevent the chimney re from reoccurring next time you light the stove.
If the chimney re does not extinguish after closing all the vents and door then you must
contact the re brigade immediately, do not attempt to ght the re yourself. After any chimney
re your chimney should be carefully examined for damage before you attempt to relight your
stove, contact a professional for advice if necessary.
Placement & Fixing Advice
The placement of the stove is very important not only for safety reasons, but also to get the
best performance out of your appliance. Connecting the rear air supply to an external source
of cold air can improve the efciency of your stove, but it is not essential to do this for the
stove to perform normally. The below diagrams show examples of free standing and external
air supply installations. For more information see the Hearth & Fire Surround section.

14
The minimum distance from the rear of the stove to a wall is 75mm, and 300mm to either
side of the appliance. No combustible material should be within this area (see below). We
also recommend at least 1000mm clearance around the stove to glass (excluding hearths).
Please note the Hot Zone to the front of the stove extends 1000mm from the window and
ends in line with each side of the door edge. This area can be 90oC, so we do not recommend
any combustibles in this area.
Fixing Points
If you would like to x the stove to the ground, you can do this using the xing points shown
below. For anchoring the Pedestal model to your hearth you will need x4 M12 bolts and x4
M12 nuts (not supplied).The Log Store model has M12 nuts built into the base, therefore you
will only require x4 M12 bolts (not supplied) for this model.

Installation Instructions
Health & Safety Precautions
Before you begin the installation process there are a number of things to consider:
• You must NOT have an extractor fan tted in the same room as the stove, regardless
of its distance from the replace. This is because it will make the stove emit dangerous
fumes into the room.
• If work needs to be carried out that could potentially disturb any asbestos in your home
then ensure appropriate protection is worn before commencing work.
• The room you are tting the stove in needs to have an adequate air supply, especially
if the room has double glazed windows. We recommend you check this with your local
building control ofcer and adhere to the building regulations requirements for providing
oxygen into the room (your installer will conrm this with you).
• The requirements of both the BS 8303 and BS EN 15287-1:2007+A1:2010 standards
must be fullled.
• We recommend you only use a HETAS Approved Installer to
carry out the stove installation. See hetas.co.uk.
• All local authority laws and building regulations must be
adhered to before installation and the required permission to
install must be obtained.
• Ensure you have a carbon monoxide and smoke alarm tted in the same room as the
appliance.
Chimney
For the stove to perform correctly and safely your chimney height must not be less than 4 metres
high, this height is taken from the outlet of the stove body to the very top of the chimney. The
outlet on our stove is 6 inches in diameter, therefore your chimney must have a minimum width
of 6 inches but preferably be 8-9 inches wide. Your chimney can be either square or circular, as
long as it meets the minimum width specications.
If installing a stove into an existing replace, it must be swept and inspected to ensure that it is
in good condition and suitable for the type of stove you are installing. If any cracks, blockages
or excessive cross sections are found then you should consult a professional regarding getting
your chimney lined. The type of fuel you wish to burn needs to be considered before getting your
chimney lined so that a suitable lining is used.
If there is an excessive draw with the chimney then we recommend a draught stabilizer be tted.
Alternatively if there is too little draw or down-draught then you must consult a professional before
lighting your stove. You should have a minimum draw of 2.5mm water gauge.
Hearth & Fire Surround
The stove must be installed on a at reproof hearth for stability and the area in front and around
the re must be clear of any combustible materials. The stove should not be at against a wall,
we recommend a minimum clearance of 75mm to prevent restricting airow.

Building regulations regarding these appliances govern that the hearth must extend at least
300mm out in front of the stove and 250mm to each side. For safety we recommend that you
ensure there is a minimum of 300mm clearance around the entire appliance. This appliance
needs a good amount of air circulation around it, however if you are installing the stove in a
replace ensure that there is at least 250mm gap to each side and at least 300mm above the top
of the stove in order to prevent overheating and allow for good heat output.
You may wish to connect the rear Air Wash vent up to an external supply of air, this can be done
provided the connection is secure and doesn’t prevent the Air Wash Control from opening and
closing fully. A rear clearance of 75mm is still recommended in these circumstances. Also you will
need to consider how close your mantelpiece or any other objects directly above the replace
are, to prevent damage due to high temperatures.
Flue Connection
The Zeta Series has a top output connection, the type of installation that is best for your home
will depend on the chosen location for the stove. You must ensure that all building and health and
safety regulations that apply to your chosen type of installation are conformed to before you begin
to use the stove. Your stove will normally be delivered assembled ready for connection.
Connecting The Flue
The ue collar must be sealed with re cement and all ue connections must be well sealed.
Any horizontal sections of ue must not be longer than 150mm. With most ue connections
your installer should t a soot door in your chimney to allow access to sweep it, alternatively this
chimney can be swept through the stove (see Chimney Sweeping section).
Permanent Air Vent
In order for this stove to operate safely and efciently it requires an adequate supply of air. This
stove is rated at over 5kW, therefore a permanently open air vent is required. Please refer to
Document J, 2.3 - Table 1 for more information (link below).
http://www.planningportal.gov.uk/uploads/br/BR_PDF_AD_J_2010_V2.pdf
On Delivery Of The Stove
Please ensure that the vermiculite bricks, throat plate and bafe plate have not moved in transit
(see page 18) and that the glass window is intact. Also check that you have all the required parts
(see back page) before installation.
After Installation
Upon completion of the installation you should allow time for the re cement and mortar to dry out
and set properly. Once dry you may begin preparing the re for its rst re. Ensure that the throat
plate, bafe plate and front grill are in place and that the door and vents close properly before
lighting.
When you’re ready to start the re, follow the instructions detailed in the Lighting section relevant
to your type of fuel. Once alight, check that the fumes and smoke are being drawn up through the
chimney correctly and that all joints and seals are not emitting fumes.
Your installer should advise on the operation and maintenance of your stove and chimney and
retain this manual for future reference.
