Firing rates
During operation, burner output varies between:
–
a
MAXIMUM OUTPUT
, which must not be greater than the
maximum limit given on the diagram,
–
and a
MINIMUM OUTPUT
, which must not be lower than the
minimum limit in the diagram.
WARNING
The firing rate value range has been obtained con-
sidering an ambient temperature of 68 °F (20 °C),
and an atmospheric pressure of 394” WC.
The firing rate areas have been reduced by 10%
with respect to the maximum range that can be
reached.
