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 and House Coal 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. Also when burning smokeless fuels, the upper bafe vermiculite board (throat plate reboard) must be removed. Please
refer to page 19 for instructions on how to do this.

Operating Instructions
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. This slider operates the clean glass air wash system which assists in helping to prevent the glass blackening up. It also operates the Eco­Cleanburn 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 left hand slider (Fig. 2) 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 right hand slider (Fig. 1) 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. Also
note the required riddle grate position for each type of fuel. To change the riddle grate position
insert handle (see Fig. 4), then push backwards to close the grate or pull forward to open the
grate.

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 right hand side of the door, pull the handle out to
open the door and insert your fuel (Ensure riddle grate is in the appropriate position for 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 right hand primary air slider is open (See Fig. 1) on the stove before closing the door, 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 7. Once fully lit, you
can partially close the primary slider.
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 Instructions
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 right hand primary slider and the secondary
and tertiary slider bar below 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 left slider bar. The primary air control slider should only be left fully open when lighting or when rapid burning is needed. If the slider is left open for long periods then over-ring may occur. Once lit we recommend the primary slider be left slightly open, and adjust accordingly to control the re.
The door handle, two control bars (air wash and primary) and riddle bar 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 50mm below the tertiary holes 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 Handle
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 19.

Operating Instructions
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.
12
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.

Free Standing External Air Supply
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.
75mm
COMBUSTIBLE WALL
75mm
COMBUSTIBLE WALL
14
The minimum distance from the rear of the stove to a wall is 75mm, and 500mm to either side of the appliance. No combustible material should be within this area (see below, left).
There is however an exception made when the stove is placed in a corner, the closest point of the stove to both walls should be at least 100mm (see below, right). 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:
• We recommend you avoid tting the stove in the same room as an extractor fan. However, if this is unaviodable, seek specialist advice to ensure safe installation and
operation of the stove.
• 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 5 inches in diameter, therefore your chimney must have a minimum width of 5 inches but preferably be 7-8 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
Installation Instructions
16
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).
On Delivery Of The Stove
Please ensure that the vermiculite bricks, throat plate and bafe plate have not moved in transit (see page 19) 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.

This warranty is not transferable and is extended only to, and solely for, the benet of the
original purchaser of the stove. Please retain your dated sales receipt as a proof of purchase.

DEFRA Requirements
DEFRA Requirements – using this stove in Designated Smoke Control Areas
The Zeta 5Kw range are DEFRA exempt so they can be used to burn well seasoned wood in a smoke free zone (designated smoke control area).
The Zeta 5 range is also a multi-fuel stove so smoke fuel mineral fuels can also be burn on the stove in designated smoke free zone (designated smoke control area).
The Clean Air Act 1993 and Smoke Control Areas
Under the Clean Air Act local authorities may declare the whole or part of the district of the authority to be a smoke control area. It is an offence to emit smoke from a chimney of a building, from a furnace or from any xed boiler if located in a designated smoke control area. It is also an offence to acquire an “unauthorised fuel” for use within a smoke control area unless it is used in an “exempt” appliance (“exempted” from the controls which
generally apply in the smoke control area.
The Secretary of State for Environment, Food and Rural Affairs has powers under the Act to authorise smokeless fuels or exempt appliances for use in smoke control areas in England. In Scotland and Wales this power rests with Ministers in the devolved administrations for those countries. Separate legislation, the Clean Air (Northern Ireland) Order 1981, applies in Northern Ireland.
Therefore it is a requirement that fuels burnt or obtained for use in smoke control areas have been “authorised” in Regulations and that appliances used to burn solid fuel in those areas (other than “authorised” fuels) have been exempted by an Order made and signed by the Secretary of State or Minister in the devolved administrations.
Further information on the requirements of the Clean Air Act can be found at: http://smokecontrol.defra.gov.uk/
Your local authority is responsible for implementing the Clean Air Act 1993 including designation and supervision
of smoke control areas and you can contact them for details of Clean Air Act requirements
Recommend Fuels for use in a Designated Smoke Control Areas
The Zeta 5 multi-fuel stove appliance has been recommended as suitable for use in smoke control areas when burning:
• Well seasoned woods with a moisture content less than 20%. (If you are unsure of the moisture content in the wood you can buy a moisture tester from you local stove retailer these on average cost less than £20)
• Smokeless Mineral Fuels. Such as ANCIT. When purchasing these products it will state on the packaging that it is suitable for use in a designated smoke control areas
Please refer to page 6 for more details.
Refuelling on to a low re bed
If there is insufcient burning material in the re-bed to light a new fuel charge, excessive smoke emission can occur. Refuelling must be carried out onto a sufcient quantity of glowing embers and ash that the new fuel charge will ignite in a reasonable period. If there are too few embers in the re bed, add suitable kindling to prevent excessive smoke
Fuel overloading
The maximum amount of fuel specied in this manual should not be exceeded, overloading can cause excess
smoke. Please refer to page 9.
Do Not Operate this appliance with door left open. Operation with the door open can cause excess smoke. The appliance must not be operated with the appliance door left open.
Air controls (primary, secondary and tertiary air controls)
The air controls must be used in accordance with this manual as detailed on pages 8 to 11.
