Worcester Greenstyle Hanbury 4 Installation, Servicing And User Instructions Manual page 24

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.
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 damper operation setting. Real
operating conditions may give very different results than those 1 2 3 4
obtained during testing according to the species of wood used, its
moisture content, the size and density of the pieces, the length of
9 10 11 12
the chimney, altitude and outside temperature.
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 wood stove. Never put
wood above the firebrick lining of the firebox.
RELOADING
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 wood stove, we recommend you to
operate it with a wood load approximately equivalent to the height
9 10 11 12
of fire bricks. Do not stack wood higher than the firebrick.
It is important to note that wood combustion consumes ambient
oxygen in the room.

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. If creosote has
accumulated (3mm or more), it should be removed to reduce the
risk of a chimney fire.
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.
