The firing rates were obtained in spe-

cial test boilers, according to EN 676

regulations.

Fig. 4 indicates the diameter and

length of the test combustion chamber.

Example

Output 756 kW (650 Mcal/h):

diameter 60 cm,

length 2 m.

The coupling is ensured when the

boiler is EC type-approved; for boilers

or ovens with combustion chambers of

very different dimensions compared to

those shown in the diagram of Fig. 4,

preliminary checks are recommended.

The maximum output is chosen within area A (and B for RS

130/E MZ) of the diagram.

Note: to use area B (RS 130/E MZ) as well, the pre-calibration of

the combustion head is necessary, as explained in Chap. 4.6.

The minimum output must not be lower than the minimum limit

of the diagram.

Warning

The firing rate was obtained considering a room temperature of

20°C and an atmospheric pressure of 1013 mbar (approx. 0 m

above sea level), with the combustion head adjusted as shown

in Ch. 4.7.
