Fig. 5 Chimney caps
According to Standard UNI 7429, the chimney cap must meet several requirements; above all, it must have a useful
outlet cross section at least double that of the flue. It is also advisable to install an "antiwind" cap that guarantees
fume exhaust even in the presence of strong horizontal winds.
3 STOVE USE
3.1 Introduction
Never leave children unsupervised in the vicinity of the stove; the risk of burns caused by the hot parts is very high.
•
Also:
•
never use the stove with the fire door open;
•
never store firelighters or other easily combustible materials near the stove;
•
never try to move or lift the stove by the handles.
3.2 Startup
When lighting the stove the first time, bad odours may be created, therefore air the room thoroughly.
When lighting the stove the first time, allow it to burn with a low flame for several hours (air control on ash door open
30%) and with very little fuel.
The heat can then be increased a little at a time, so that the stove expands slowly and the sealants and putties dry.
During the heating and cooling cycles, the combustion chamber in refractory cement undergoes thermal stress and
expansion causing fine cracks to form, which do not affect stove efficiency or its service life.
3.3 Lighting and controlling the fire
To light the fire, it is advisable to use kindling and newspaper, or other means available on the market (excluding any
flammable liquid substance).
During the lighting stage, the air controls on the fire door must be fully open; once the stove is lit they are used to
regulate stove heat output. During this stage it is also advisable to open the bypass damper by moving the lever to
position A.
When the stove is hot, adjust the primary air and secondary air as described in the following paragraph and close the
bypass damper by moving the lever to position Z.
•
Never use petrol, alcohol or other flammable liquids to light the fire.
