Safety Notes for Your Guidance
FIRES CAN BE DANGEROUS.
Always use a fire guard in the presence of children, the elderly
or the infirm. Inform all persons the dangers of high temperatures
during operation of the appliance including the stove pipe.
Use operating tools provided.
DO NOT OVER FIRE.
It is possible to fire the stove beyond its design capacity. This could
damage the stove, so watch for signs of over firing. If any part of
the stove starts to glow red, the stove is in an over fire situation
and the controls should be adjusted accordingly to reduce air
intake. Never leave the stove unattended for long periods without
adjusting the controls to a safe setting. Careful air supply control
should be exercised at all times.
Warning - Fume Emissions
Properly installed and operated, this appliance will not emit fumes.
Occasional fumes from de-ashing and refuelling may occur.
Persistent fume emission must not be tolerated. If fume emission
does persist, then the following immediate action must be taken:
1. Open doors and windows to ventilate the room.
2. Let the fire out, or eject and safely dispose of fuel from the
appliance.
3. When the stove has cooled, check for chimney flue blockage
and clean if required.
4. Do not attempt to relight the fire until the cause has been
identified. If necessary seek professional advice.

General Maintenance

Baffle Plate: This should be removed at least once a month to
prevent any build up of soot or ash, which could lead to blocked
flue ways and dangerous fume emission. This must be done when
the stove is cold. Once the baffle plate is removed the chimney/
flueway can be swept through the appliance.
The baffle plate holds the side bricks in position and uses two
extended tabs to locate on top of the bricks while the rear edge
rests on the tertiary air bar. To facilitate easy removal the log bar
can be removed by unscrewing the transport fixing bolt on the
underside (It is not necessary to refit this bolt for normal stove
operation). Please note the baffle plate position before removal.
To remove the baffle plate, lift the front edge and slide it forwards
until it drops down clearing the front edge of the side bricks.
The rear of the plate should now clear the back brick & airwash.
Holding the plate in horizontal position, carefully rotate the baffle
plate clockwise until the tabs on the lower side becomes free. The
bottom side can then be pulled forward from the side brick and the
plate can be removed.
Stove Body: The stove is finished with a heat resistant paint and
this can be cleaned with a soft brush. Do not clean while the stove
is hot, wait until it has cooled down. The finish can be renovated
with a suitable brand of stove paint.
Glass Panels: Clean the glass panels when cool with a proprietary
glass cleaner or some damp newspaper. Do not use abrasive
materials as these can scratch the glass and make subsequent
cleaning more difficult. Wet logs on heated glass, a badly aimed
poker or heavy slamming of the doors could crack the glass panel.
The glass should not fracture from heat.

Chimney: Check your chimney each year before starting to use
your stove for the winter. Birds may have nested in the chimney
or masonry may have cracked. Both chimney and flue pipe must
be swept at least once a year by a Qualified Chimney Sweep.

Troubleshooting

1. Poor heat output
a. Stove too small for room: Seek advice from a Qualified Heating
Engineer as to (kW) output required for the room size. As a
guideline the volume of the room in cubic feet divided by 500;
e.g. room 15'x15'x8' would require 3.6kW approx.
b. Chimney and/or flue pipe restricted, room ventilation restricted:
On installation these should have been checked but regular
maintenance is necessary as conditions can change; e.g. soot
build up, birds nesting, masonry fall, dust build up or furniture
blocking vents.
c. Poor quality fuel: Only burn dry seasoned timber, soft woods
have a lower heat output than hard woods per hour. Solid
fuels vary in heat value; check with your coal merchant as to
suitability.
2. Dirty Glass Panel
a. Generally caused by poor fuel quality, damp fuel or burning
wood that has not been properly seasoned.
b. Airslide not in correct position for the fuel type, e.g. on solid fuel
setting when burning wood.
c. Fire burning too low, open air vents on stove to create hot fire;
this may 'burn' glass clean.
d. If glass requires cleaning use glass cleaner recommended by
your supplier; only use glass cleaner on cold glass. DO NOT
USE any abrasives or scrapers as these will scratch glass and
increase future tar build up making it harder to clean.
3. Unburnt Fuel in Firebox
Insufficient air reaching fuel causing it to go out. Open the air
slide, this will supply combustion air to burn fuel fully (unless it
has insufficient heat to ignite or has already extinguished). Check
if the ash pan is full and empty if required. De-ash to make sure
the grate is not blocked and check for jammed clinker or nails
when the fire is out and the stove has cooled. A small amount of
unburnt clinker is normal after the fire has extinguished and the
amount left is dependent on fuel type.
4. Smoke and Fumes Entering Room
These are very dangerous and must NOT be tolerated. Open
window and allow fire to burn out. Seek expert advice immediately.
DO NOT USE stove until the problem is solved.
5. Chimney Fire
Identified by loud roaring sounds, dense smoke and sparks emitting
from chimney. Shut down the air supply by closing air vents, close
stove door fully and call fire brigade immediately.
Chimneys must be swept at least once anually, more frequently if
smokey fuels are used. Regular chimney maintenance will prevent
chimney fires. Seek advice from a Qualified Chimney Sweep.
