3.18 VARIABLE HEAT POWER.
N.B.: the pressures indicated in the table
represent the differences of pressures at the
ends of the Venturi mixer and can be measured
from the pressure point in the upper part of the
sealed chamber (see pressure test 32 and 33 Fig.
1-21). e adjustments must be performed using
a digital dierential manometer with a scale in
tenths of mm or Pascal. e power data in the
table has been obtained with intake-exhaust pipe
measuring 0.5 m in length. Gas ow rates refer
to heating values below a temperature of 15°C
and at a pressure of 1013 mbar. Burner pressure
values refer to use of gas at 15°C.
