3.18 VARIABLE HEAT OUTPUT.
N.B.: the pressures indicated in the table repre-
sent the dierence in existing pressures between
the gas valve outlet and the combustion chamber.
e adjustments should therefore, be carried
out using a dierential manometer (small “U”-
shaped column or digital manometer) with the
probes inserted in the pressure test gas valve
outlet and on the sealed chamber positive pres-
sure test. e power data in the table has been
obtained with intake-exhaust pipe measuring
0.5m in length. Gas ow rates refer to heating
power below a temperature of 15°C and at a
pressure of 1013 mbar. Burner pressure values
refer to use of gas at 15°C.
