- the use of high-resin softwood as fuel (use dry hardwood fuel in compliance with the firebox-
-operation manual).
e) The operation can be affected by weather conditions (air humidity, fog, wind, air pressure), and
sometimes by surrounding tall buildings.
If the problem persists, have a chimney sweep company carry out a study and issue a report to confirm
the cause of such disruption and to advise on the best solution to the problem.
CAUTION! As a result of slow burning, an excessive amount of organic combustion products is produ-
ced (soot and water vapour), which forms ignitable creosote in the smoke duct.
This leads to violent combustion in the chimney flue (large flame and high temperature) referred to
as a chimney fire.
If such a phenomenon occurs, do the following
• close the air intake;
• ensure that the door is closed correctly;
• call your local Fire Service.

APPLIANCE DESCRIPTION AND DESIGN
The steel shell is a principal part of the heater (Figure 1), containing the combustion chamber. The
combustion chamber front wall consists of a steel door fitted with homogeneous heat-proof glass
and a closing lock.
The doors are set in a frame. The combustion chamber is lined with Acumotte panels. The base of the fi-
rebox consists of a two-shell floor, which also forms the air-intake chamber. The air intake is made with
an external air-intake connector with a diameter of fi = 125 mm, fitted with a control device. The com-
bustion-chamber air feed also involves the holes located in the back wall – a flue-gas-burnout system.
The base supports a cast-iron fire grate, on which fuel is burnt. The fire grate should be laid with its
fins facing upwards.
Burning waste: ash and residual fuel accumulate in a replaceable ash pan situated under the fire grate.
There is a baffle over the combustion chamber. It provides a natural convection conduit for flue-gas
flow to enhance heat exchange.
The air is controlled with a lever. Open the primary air supply by moving the control lever to the left-
most position, and close the air intake by moving the lever to the rightmost position.
During the firebox's operation, the flue gases ascend the walls of the combustion chamber, then they
move under the lower and upper baffles and continue up to the flue pipe, to get to the chimney via
the smoke duct.
The air damper is fitted in the air-intake duct outside the building, and it controls the amount of air
taken in by the fireplace to ensure the optimal burning process.
The AB Stove model is equipped with a revolving leg operated by means of a release lever, which,
when pulled, allows the rotating of the stove body, thanks to bearings fitted on the leg and under the
heater flue pipe.
