Franco Belge will not be responsible for damages on
parts of the appliance due to the use of prohibited fuel
or due to an alteration of the appliance or its
installation
3.1. Fuel
-Use hard wood logs, which have been cut for at least
two years and stored, under shelter
-Hardwood has a higher calorific value per cu metre
-Large logs must be split and cut to a usable length,
before being stored in a sheltered and ventilated
place
Recommended fuel
•Firewood : Yoke-elm
Suitable fuel
•Firewood : Oak, ash, maple, birch, elm, beech, etc
Prohibited fuel
•Any form of coal
•“Green wood” Green or damp wood reduces stove
efficiency and soils the glass, the internal walls and the
flue (soot, tar, etc )
-“Recovered wood” Burning treated wood (railway
sleepers, telegraph poles, offcuts of plywood or chip
board, pallets, etc ) quickly clogs the flue ways (soot,
tar, etc ), pollutes the environment (pollution and
smell, etc ) and cause the fire to burn too quickly and
overheat
“Green wood” and “recovered wood” can cause a
chimney fire
3.2. Lighting
-Open the air regulation flap,
-open the flue damper and loading door,
-place the grate on scrunched up paper, some
kinderling and some hardwood of small diameter,
-set light to the paper and close the glass door
-At the first lighting, the fire must be progressively
increased to allow the various parts to expand
normally and to dry up
-When the wood is well lit partially close the air
regulator, load the appliance without excess and close
the flue damper
Note : When the fire is lit for the first time, the stove may
give off fumes from the new paint This is normal but
ensure the room is well ventilated during the first few
hours operation
3.3. Air convection principle
(model 634 10 44 only) Two fans with automatic start to
accelerate the hot air convection,
The air leaving the heat exchanger is accelereted by the
automatic start of the fans when the hot air
temperature is more than 50 °C The fans stop when the
air temperature fall down
3.4. Combustion
The appliance must function all door properly closed,
the speed regulation being carried out using the air
regulation on the ash pan door
