If the flue is not perpendicular to the chimney it is advisable to make the connection with special steel fittings that

allow a maximum slope of 45° .

If the walls and ceiling are made of flammable materials, the parts in contact with the flue must be suitably

insulated. All connection joints must be carefully sealed, in particular where the connection enters the flue.

If there are several heating stoves in the same home, each must have its own flue. It is inadvisable to make

openings in the flue for other appliances, since the draught could be negatively affected.

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.

Carefully observe the following rules:

- never use the stove with the door open;

- do not keep firelighters or easily flammable materials near the stove;

- do not move or lift the stove using the handles.

3.2 Adjusting the combustion air

Primary air:

the primary air is adjusted using the manual revolving controls on the firebox door, and feeds the fire through the

grate.

Secondary air:

the secondary air enters the stove by means of the sliding control located above the firebox door.

Optimum combustion conditions exist when, on loading wood, the combustion air feeds the flame by entering

through the grille, whereas the secondary air, entering through the control, enables the completion of combustion

in the upper part of the firebox.

3.3 Start-up

With first start-up, bad odours may be created, therefore air the room thoroughly especially when lighting the

stove the first time.

When lighting the stove the first time, allow it to burn with a low flame for several hours (primary air control open

30%).

The heat can then be increased a little at a time, so that the stove expands slowly and the paint and putty dry.

3.4 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 solid or liquid flammable and/or explosive substance).

The air control on the door, in the ash zone, must be open and is for adjusting stove heat output after the lighting

stage.
