Variable Heat Power - Immergas INTEC 30 System External Installation Instructions Manual

3.15 VARIABLE HEAT POWER.

N.B.: the pressures indicated in the table repre-
sent 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 15 and 16 Fig. 1-11).

The adjustments must be performed using a
digital differential manometer with a scale in
tenths of mm or Pascal. The power data in the
table has been obtained with intake-exhaust pipe
measuring 0.5 m in length. Gas flow rates refer
