Installation and Operating Instructions for Bohemia Multi Fuel Stoves Page 3 of 6
If the stove is operated at this optimum level very clean combustion can be achieved with little or no smoke visible from
the chimney.
The best way to light the fire is to use rolled-up balls of paper or firelighters and small pieces of wood laid on the fire
grate. Open both the primary and secondary air intake. When the wood is burning well (after approximately 10 to 20
minutes), the next load of fuel can be added. Take care that the fuel is not stacked too closely. It is important to
establish a really good hot fire before closing down the air vents. The primary and secondary airflows can now be
regulated as necessary
SAFETY PRECAUTIONS
A risk of blowback can arise if too much dry wood is placed in the stove and burnt with insufficient combustion air.
This may result in the production of gaseous compounds which can ignite if the intake of primary and secondary air is
insufficient and the firebox temperature too low.
To achieve optimal firing and the best possible heat output, the primary and secondary air intakes must be correctly
adjusted. As a general rule, the fire should be regulated using secondary air supply, with which smoke and gases are
ignited. This produces a high level of efficiency and also keeps the viewing window clean because the secondary air
„washes over‟ the glass.
For wood burning it is an advantage always to leave some ash lying in the bottom of the combustion chamber.
Take care when emptying the ash pan, as cinders can continue to burn in the ash for long periods of time.
NOTE: It is advisable always to leave the top air control slightly open.
Please note that the stove will, naturally, produce soot if both the primary and secondary air intakes are closed
completely. This will prevent oxygen from being drawn into the stove, and the viewing window and other parts will
become covered with soot and/or tar.
The nominal output is the output to which the stove has been tested. In practice, the stove burns with a heat output range
between its minimum and maximum ratings.
MAINTENANCE OF MATT BLACK PAINT FINISH
The surface of the stove has been treated with heat-resistant paint. The stove should be cleaned with a soft brush. Any
damage to the surface in the form of chips or scratches can be repaired using touch -up paint, which is available in spray
cans. If the stove has become grey in colour due to overheating, touch-up paint of this kind can be used to repaint the
stove entirely. Alternatively the stove can be maintained with a traditional type of stove polish of which there are
several proprietary makes available. Do not use an aerosol spray when the stove is alight.
CLEANING THE GLASS
Incorrect firing, for example using wet wood, or slow burning can result in the viewing window becoming covered in
soot. This soot can be easily and effectively removed by using a damp cloth or when necessary a proprietary stove glass
cleaner or an ordinary scouring liquid, when the glass is cold
OPERATIONAL PROBLEMS
In the event of smoke or malodorous fumes being produced, you must first check to see whether the chimney is blocked.
The chimney must, of course, always provide the minimum draught necessary to ensure that it is possible to regulate the
fire. However, the chimney draught may also be affected by weather conditions. Both wind and temperature can affect
the performance of a chimney.
In cases where the wood burns too quickly, this may be due to excessive chimney draught. You should also check to
make sure that the door seal is intact. If the stove produces too little heat, this may be due to the fact that you are firing
with wet wood. A large proportion of the heat output will be used to dry the wood, resulting in both uneconomical
heating and an increased risk of soot and tar deposits forming in the chimney.
STANDING DOWN AT THE END OF THE SEASON
At the end of the burning season the stove should be prepared for the stand down period, this is to prevent corrosion both
in the stove and flue system.
The stove should be cleared of all ash, the baffle and flue ways cleared of soot and fly ash and the chimney swept.
All air vents should be in the open position and it is recommended that the door is left ajar to ventilate the chimney.
This is the ideal time to check for parts that may need replacing and to lubricate door hinges and catches. Also it is
recommended that all screws holding the glass in place are removed and replaced with a high temperature lubricant.
