OPERATING INSTRUCTIONS
8.1 Wood:- Burn only seasoned timber, with a moisture
content of less than 20%. In most cases this would require
drying cut wood for 12 to 18 months before use. Poor
quality timber could cause low combustion efficiency,
produce large amounts of harmful condensation, which
could reduce the effectiveness of the airwash system, and
ultimately the life of the stove Do not burn painted,
impregnated wood or manufactured board products.
The symptoms of poor performance related to wet wood
include:-
• Difficulty getting a fire going and keeping it burning well,
• Smoky fires with little flame,
• Dirty glass,
• Rapid creosote build-up in the chimney,
• Low heat output,
• Short burn times, excessive fuel consumption and
blue/grey smoke from the chimney.
To help avoid large build-ups of tars and creosote within
the stove and the flue system, it is recommended to burn at
high output for at least 30 minutes each day. The use of
Stovax Protector chimney cleaner will also help to reduce
this problem.
8.2 Solid fuel:- Burn manufactured smokeless fuels, or
anthracite, listed as suitable for use with closed heating
stoves. Do not burn ‘petro-coke’ or other petroleum
based fuels, as this will invalidate and product
guarantee.
8.3 Fuel consumption: -
Wood:- Approximately 1.8 kg per hour of fuel under ideal
conditions with the Airwash control fully OPEN and the
Primary air control fully CLOSED.
Solid Fuel:- Approximately 0.7 kg per hour of fuel under
ideal conditions with the Airwash control fully CLOSED and
the Primary air control fully OPEN.
If you require advice on suitable solid fuels contact your
local Approved Coal Merchant. Details can be obtained by
ringing the Solid Fuel Association advice line on Freephone
0800 600 000. Or their web site at www.solifuel.co.uk
A number of factors can effect the performance of the
Stockton stove. Some of these are listed.
Fuel Quality (Wood)
Use only seasoned wood with a moisture content of less
than 20%. Symptoms of poor performance related to wet
woods include: -
• difficulty getting a fire going and keeping it burning well,
• smoky fires with little flame,
• dirty glass,
• dirty firebricks
• rapid creosote build-up in the chimney,
• low heat output,
• Short burn times and blue/grey smoke from the chimney.
Fuel Quality (Solid Fuel)
Use only recommended solid fuels, which are approved for
use with closed appliances. Symptoms of poor performance
related to unsuitable fuels include: -
• difficulty getting a fire going and keeping it burning well,
• smoky fires with little flame,
• dirty glass,
• dirty firebricks
• short life span for grate, baffles and internal firebricks,
• permanent staining of glass.
Flue Draught
The chimney has two main functions, which are, to safely
remove the smoke, gases and fumes from the house, and to
provide a sufficient amount of draught (suction) in the
Stockton stove to ensure that the fire is kept burning.
Draught is caused by the rising hot air in the chimney when
the Stockton stove is lit.
Symptoms of poor performance related to flue draught
include: -
• excessive fuel consumption (high flue draught)
• poor burning control, overheating (high flue draught)
• wind noise from air controls (high flue draught)
• difficulty getting a fire going and keeping it burning well
(low flue draught)
• low heat output (low flue draught)
• smoke entering room when doors opened (low flue
draught)
