OPERATING INSTRUCTIONS
Recommended Fuels (without multi-fuel conversion installed)
Hardwood logs: such as ash, oak and beech which have been cut for at least 12 months with a
maximum moisture content of 20% and stored under shelter.
Maximum log length: 300mm length with a maximum depth of 125mm.
Recommended Fuels (with multi-fuel conversion installed)
Smokeless Mineral Fuel: Such as Maxibrite which is approved for use in smoke control areas.
Prohibited Fuels
Green wood: i.e. wood which is less than 12 months old with a moisture content of above 20%
Recovered wood: i.e. pallets, fencing panel, railway sleepers etc. These will have been
impregnated with wood preservatives which can cause issues with the flue and possibly overheat
the appliance.
Liquid fuels.
Peat based Fuels
Household waste: Burning this can produce harmful fumes.
Petroleum based coke: This burns with an extremely high heat which can cause damage to the
appliance.
Caution - The stove and flue pipe will become extremely hot during use; take care especially when
children or the infirm are present. Do not store flammable materials near to the stove. Any
combustible furnishings must be at least 800mm away.
Initial Firing of the appliance
Wood likes to burn on a flat base with air flowing over the top and minimal air underneath. The air
controls on this stove allow you to completely cut off the primary air under the fire whilst leaving the
secondary/tertiary air open for burn control.
Please note that the first fire you light in your stove should be small and operated with the all air
inlets set as low as possible –the air control should be set in pushed back position to achieve this.
During this initial firing it is normal to experience fumes and a light haze from the appliance as the
paint cures during which you must ensure the room is well ventilated.
Air Controls
The air controls for the appliance are located underneath the stove at front. When pulled forward
they are in the fully open position and when pushed back are fully closed. The function of each
control is as follow (from left to right as you look at the appliance)
Left - Tertiary Air (for the air supply above the firebed)
Centre –Primary (for the air supply under the grate when using multi fuel conversion kit)
Right –Secondary (for the air supply above the stove door glass)

OPERATING INSTRUCTIONS
Normal Operation (after initial firing) –wood burning
To establish clean burning, it is important to get the appliance hot as quickly as possible. This can be
achieved with the following ignition regime:-
I. Set the air control to the maximum setting by pulling the air controls forward.
II. Light a double-handful of kindling with a couple of firelighters, with the door 5-10mm open.
After 3 minutes a hot fuel bed will have been established, then add two small sized logs (each
about half the size of a "standard" 9 inch log).
III. Let these burn well for another 3 minutes , with the door still open 5-10mm.
Normal Operation (after initial firing) –Mineral Smokeless (Solid Fuel)
I. Set the air control to the maximum setting by pulling the air controls forward.
II. Light a double-handful of kindling with a couple of firelighters, with the door 5-10mm open.
After 3 minutes a hot fuel bed will have been established, at this point the mineral fuel can be
added to the fuel bed.
Refuelling of the appliance at nominal output would be approximately every 4 hours. It is important
to ensure that the fuel bed does not exceed the height of the fire bars at the front and does not
exceed a 30 –degree incline from front to back. Ensure you refuel onto a bed of hot embers to
achieve the best burn. When using solid mineral fuels, we suggest you keep the secondary air control
in the closed position, so it can burn at maximum efficiency. At this time the primary air controls can
adjust the burn rate of the appliance.
Refuelling your stove - in order to maintain clean burning, after refuelling air control needs to be
open for 5 minutes afterwards.
Refuelling on to a low fire bed
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 onto a sufficient 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 fire
bed, add suitable kindling to prevent excessive smoke
Over Firing
Do not run the stove with the air control fully open for prolonged periods. This may result in over
firing and cause damage to the appliance invalidating your warranty
Do not leave the stove unattended during lighting. After the ignition procedure is complete, the
stove must not be operated with the door open

OPERATING INSTRUCTIONS AND WARRANTY
Fuel overloading
The maximum amount of fuel specified in this manual should not be exceeded, overloading can cause
excess smoke.
Operation 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 except as directed in the instructions.
Dampers left open
Operation with the air controls or appliance dampers open can cause excess smoke. The appliance
must not be operated with air controls, appliance dampers or door left open except as directed in the
instructions. Ash Removal - Ashes can remain hot for a long period after the fire has extinguished,
care must be take when disposing of these and ensuring they are completely cooled.
Wood Burning - Wood burns most efficiently on a bed of ashes allowing you to get the best results
from your wood burning stove. However, the ash, should not be allowed to build up excessively (no
more the 25mm in depth) on the stove base. When the appliance is cool, the ash should be swept
from the appliance taking care not to damage the lining of the stove. Sharp pointed pokers must not
be used.
Mineral fuels –The ash pan must be emptied frequently to prevent the ash tray overfilling and
restricting the airflow and preventing a good burn. The ash must not build up to the point it contacts
with the underside of the grate as this will cause distortion and significantly reduce the life of the solid
fuel grate.
Chimney Fire
In the unlikely event of a chimney fire,
If safe to do so, ensure the stove door is closed
If safe to do so, close the air control.
Evacuate the property immediately and call the fire brigade.
Do not attempt to extinguish your stove.
Do not use the appliance until the chimney/flue has been inspected by a qualified person and any
faults found have been rectified.
Persistent fume emission should not occur if the product is properly installed and operated. However,
should this happen, take immediate action as follows:-
Ventilate the room
Extinguish the fire
Check the chimney/flue for blockages and clean if required
Seek expert advice if necessary.

MAINTENANCE INSTRUCTIONS
Maintenance
Maintaining your appliance will help ensure you have many years of trouble-free use. Regular checks
of the following items is recommended: -
NOTE ALL MAINTENANCE TO BE CARRIED OUT WHEN THE APPLIANCE IS COLD
Removal of top firebrick and clear any soot build up.
Check condition of the firebricks, if these have just have hairline fractures they do not require
replacement. They will need to be replaced if larger cracks develop exposing the appliance body or
the fire brick material begins to crumble.
Using a suitable stove glass cleaner, remove any discolouration from the appliance glass.
Inspection of the rope seal on both the appliance door and the door glass to ensure this has not
deteriorated or moved.
Flue to be swept annually by a competent person, if in doubt contact a professional chimney sweep.
If the appliance has not had regular use, the appliance and flue system should be checked to ensure
it is free from blockages prior to use.
Do not use abrasive cleaners on the stove glass as you can damage the specialist coating.
‘Crazing’ in the coating of the glass can take place if incorrect fuels are used, if this occurs replace
the glass.
