Aarrow Fires Acorn 4 - Manual (Page 20)

In the morning
•Open the air control fully until embers begin
to glow brightly and place pieces of fuel on
the fire until it is well established.
WARNING: When wood is burnt slowly in a
closed appliance it produces moisture and tar,
which will create condensation and deposits in the
chimney. This effect can be minimised by burning
hard for a short period, about 20 minutes, twice a
day. It is usually convenient to do this morning and
night.
Note: To avoid chimney problems your fire should
not be burnt slowly for longer than 12 hours
without a period of fast burning.
WARNING: Properly installed, with a suitable
flue and chimney and operated and maintained
this appliance will not emit fumes into the
dwelling. Occasional fumes from the de-ashing
and re-fuelling may occur. However, persistent
fume emission is potentially dangerous and must
be investigated by a Hetas registered installer.
Stop using the appliance if you smell fumes or
see smoke escaping.
If fume emission does persist, the following
immediate actions should be taken.
•Open doors and windows to ventilate room.
•Let the fire die or extinguish and safely
dispose of fuel from the appliance.
•Check for flue or chimney blockage, and
clean if required.
Seek expert advice from your HETAS registered
installer. Do not attempt to re-light the fire until the
cause of the fume emission has been identified and
corrected
ASH REMOVAL
The appliance will require ash to be removed
periodically but an ash bed of approximately 20mm
(3/4'') should be maintained. Ash may be removed
with a small shovel whilst the fire is still lit by
raking the embers of a low fire to one side of the
fire box and carefully removing the ash, then
repeating the procedure for the other side. Care
must be taken not to risk burning of hands or
household objects from falling embers.
DE - ASHING
It is necessary to maintain an ash layer on the upper
surface of the grate bars, in order to protect them so
de-ashing should cease as soon as the first red
embers drop into the ash pan. Further de-ashing
will cause heat build-up under the grate, which will
considerably shorten its life. This operation should
be carried out with the doors closed to prevent dust
escaping into the room.
•Move up and down vigorously the riddling
lever (ash will fall into the ash pan beneath
the grate).
•When de-ashing is complete re-set grate to
previous position.
• Empty ash pan.
Note: Do not force the riddling mechanism.
TO EMPTY THE ASH PAN Open the fire
doors. Fit the fork end of the operating tool into the
ash pan and remove from the ash pit chamber.
WARNING: The ash can be very hot. Empty only
to a metal container. Even if the ash appears cold,
red-hot pieces of ash may be concealed and could
easily start a fire or cause an injury.
CLINKER
The formation of clinker suggests that the unit is
being over-fired. Any clinker forming on the grate
should be removed when cold.
OVER-FIRING
Do not over fire your appliance. Using flammable
liquids or too much wood or firing the stove at
maximum, for prolonged periods may result in
over-firing. If the chimney connector or casing glows
red the appliance is being over-fired. If this occurs
immediately close all air inlets to the appliance to
reduce the air supply to the fire. Should a chimney
fire occur immediately close the appliance down.
Get everyone out of the house and call the fire
brigade. A chimney fire may cause structural
damage to the chimney. Do not use the appliance
until the chimney and connector have been
inspected and any damaged parts have been repaired
or replaced. This should be done by a competent
person such as a HETAS registered engineer.
