This stove appliance comes fitted with a draught controlled tertiary air system that burns otherwise non-combusted
gasses thus increasing heat output, decreasing unwanted emissions and improving efficiency. The Tertiary air supply to
the stove is controlled automatically by the draught in the flue and firebox. At certain stages of burning you will notice
"Whisps" of flame emerging near the air holes to the rear of the stove. This is not always visible depending upon the
fuels used and burn cycle stage so there is nothing untoward if it cannot be seen.
Grate
This stove is fitted with a riddling multifuel grate. The lever to the right hand side of the stove at low level
controls the movement of the grate, simply pull back and forth to allow the ash to fall into the ash-pan.
A build up of wood ash when burning wood will not harm the grate and wood is said to burn well on a bed
of ash but excessive wood ash build up is not recommended.
Smokeless fuel ash must be regularly emptied and NOT allowed to build up under the grate.regularly. In
case the ash builds up the underside of the grate, burnout or distortion of the grate may be caused
Ash pan
It is essential that you clean our the ash pan regularly especially when burning smokeless type fuels. Use
the supplied tool to lift the ash pan out of the stove. Do not allow smokeless coal ash to build up
underneath the fuel bed as this will cause damage to the grate. Only empty or remove ashes when they are
cold.
Fuels
This stove is fitted with a multifuel grate and is suitable for use for burning dry, seasoned logs (<20%
moisture) wood, smokeless fuel and other solid fuels. Note that the inset stove has been recommended for
use in Smoke Control Area when burning wood logs. These inset stoves can be used in Smoke Control
Areas when burning authorised solid fuels. A list of authorised fuels is available online:

Should difficulties arising over fuel quality or suitability please contact your local approved fuel merchant.
Burning Mineral Smokeless (Solid Fuel)
DO NOT have more than a 30-degree incline of the fuel bed from front to back, when you put solid mineral
fuels on the fuel bed. The height of loading fuels must not exceed the rear cast iron lining.
The refuelling intervals at nominal heat output will be approximately every 4 hours.
We suggest you refuel in time to get the best possible results. 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.
In order to prevent the ash from being stacked to the underside of the bottom grate, please always de-ash
before refuelling. Once the ash builds up, it is possible that it will restrict the airflow and cause the fire to
die. We do not recommend slumber or all night burning on this appliance.
Important! It is very important to empty the ash-pan regularly. In case the ash builds up the underside of the
grate, burnout or distortion of the grate may be caused.
Burning Wood
Move the secondary air slider (right hand lever) fully in out (Open) for maximum air to start or revive a wood
fire. Returning the lever in will reduce the air supply progressively to reduce the burn rate.
The maximum position will supply a boost of air to get new fuel burning rapidly in order to minimise smoke.
Do not leave on maximum setting as this will lead to over firing damage.
The refuelling intervals at nominal heat output will be approximately 45mins to 1.5 hours but this will depend
on fuel quality & draught from the chimney which will differ in each installation. You may load wood higher in
the stove than solid mineral fuel, but wood or logs are not permitted above the tertiary air holes , do not
touch the baffle or Ceramic glass.
Wood burns most efficiently with the primary air controls closed and the secondary
control partially open. Moving the secondary control will control the burn rate of the stove.
Wood burns best with a layer of ash on the fuel bed, and care should be taken to only remove surplus
residue from the stove timely.
We recommend you only use dry, seasoned wood as fuels; the wood should have been cut, split and
stacked for at least one year in a circulating air surround to dry out. Otherwise, wet or unseasoned wood
will cause tar deposits in the stove and unsatisfactory heat output will occur.
