Test boiler
The burner/boiler matching does not pose any problems if the
boiler is CE type-approved and its combustion chamber dimen-
sions are similar to those indicated in diagram (Fig. 3).
If the burner must be combined with a boiler that has not been CE
type-approved and/or its combustion chamber dimensions are
clearly smaller than those indicated in diagram (Fig. 3), consult
the manufacturer.
The firing rates were set in relation to special test boilers, accord-
ing to EN 676 regulations.

MODULATION RATIO
The modulation ratio, determined using test boilers according to
standard (EN 676 for gas, EN 267 for light oil), is 2.5 : 1.

The FIRING RATE area values (Fig. 2) have been
obtained considering a surrounding temperature
of 20 °C, and an atmospheric pressure of 1013
mbar (approx. 0 m above sea level) and with the
combustion head adjusted as shown on page 19.
