• The appliance start-up with designated heat load depends on connection
pressure and operational calorific value of gas.
Heat load
at G30
Heat load
at G20
Heat load
at G25
Nominal heat load is obtained with nozzles defined in table of nozzles, without
any pre-setting.
Permissibility of operation depends on the existing connection pressure:
permissible
for
connection pressure
range between
42.5
and
57.5 mbar
permissible
for
connection pressure
range between
17
and
25
mbar
permissible
for
connection pressure
range between
18
and
25
mbar
impermissible
if
pressure value is
below
42.5 mbar
or
over 57.5
mbar
.
Notify gas supplier and do

Table 3
Heat load with high setting is obtained for all burners with the use of proper nozzles.
The used nozzles should be compared with data in Table 2, in section
'Technical Data'.
-
Low heat load is eliminated. Main burners are supplied in ON/OFF mode.
-
Check operational calorific value with local gas supplier and check used nozzles
as per data in Table 2, in section 'Technical Specifications'.
