USER INSTRUCTION
CONTROLLING YOUR STOVE
The secondary air slide is located above the viewing glass. (The lower air slide below the glass is primary and is only used for
start up air and should not be left open for more than 5 minutes after starting your fire.) Sliding secondary air slide to the far
right position is fully open position. Your stove is tested for use in smoke controlled areas if operated in accordance with the
instructions below.

WARNING: Never alter the damper slide or
the adjustment range to increase firing for
any reason. Doing so could result in stove
damage and will void your warranty.
WOOD HEATING
Controlled combustion is the most efficient technique for wood
heating because it enables you to select the type of combustion you
want for each given situation. The wood will burn slowly if the wood
stove air intake control is adjusted to reduce the oxygen supply
in the combustion chamber to a minimum. On the other hand,
wood will burn quickly if the air control is adjusted to admit a larger
quantity of oxygen in the combustion chamber. When the stove is
operating at the desired temperature close the primary air control
and use the airwash to control the burn rate. Refer to the primary
air settings table for operation setting. Real operating conditions
may give very different results than those obtained during testing

and outside temperature.
RELOADING
WARNING:
• Never over fire your stove. If any part of
the stove starts to glow red, over firing is
happening. Readjust the air intake control
at a lower setting.
• The installation of a log cradle or grates
is not recommended in your stove . Never
put wood above the firebrick lining of the
firebox.
Once you have obtained a good bed of embers, you should reload
the unit. In order to do so, open the air controls to maximum a
few seconds prior to opening the stove's door. Then proceed by
opening the door very slowly; open it one or two inches for 5 to
10 seconds, before opening it completely to increase the draught
and thus eliminate the smoke which is stagnant in a state of slow
combustion in the stove. Then bring the red embers to the front of
the stove and reload the unit.
For optimal operation of your stove , we recommend you to operate
it with a wood load approximately equivalent to the height of fire

CREOSOTE -
FORMATION AND NEED FOR REMOVAL
When wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to form creosote.
The creosote vapours condense in the relatively cool chimney flue
of a slow-burning fire. As a result, creosote residue accumulates
on the flue lining. When ignited this creosote makes an extremely
hot fire. The chimney connector and chimney should be inspected
at least once every two months during the heating season to
determine if a creosote build-up has occurred.
We strongly recommend that you install a magnetic thermometer on
your smoke exhaust pipe, approximately 457mm above the stove.
This thermometer will indicate the temperature of your gas exhaust
fumes within the smoke exhaust system. The ideal temperature
for these gases is somewhere between 123°C and 270°C. Below
these temperatures, the build-up of creosote is promoted. Above
300°C, heat is wasted since a too large quantity is lost into the
atmosphere.
REFUELING
If there is insufficient burning material in the fire bed to light a new
wood log, excessive smoke emission can occur. Refueling must
be carried out onto a sufficient quality of glowing embers and ash
approximately 25 mm deep. Evenly distribute the embers over the
firebed and open the airwash control fully. The new fuel charge will
ignite in a reasonable period of time. If there are too few embers in
the fire bed, add suitable kindling to prevent excessive smoke. Do
not let the fire diminish too far before refueling. Open the door and
add fuel (taking care not to overfill). Close the door but leave the
primary and secondary air supply fully open for a few minutes until
a bright fire is achieved. The primary air should be closed and the
secondary air adjusted as necessary. You will find that a wood log
of approximately 2.5kg will produce a clean burning fire for about
1 hour .

MULTI-FUEL (BEWDLEY 3 & BEWDLEY 5 ONLY)
Start your fire as you normally would as instructed in the "IGNITION"
section of this manual. Allow the fire to become well established
before adding the 'Defra-authorised' smokeless fuel (as published
on the Defra website (https://smokecontrol.defra.gov.uk/fuels.php).

Open the Primary Air Control fully to establish a glowing bed
