TECHNICAL DATA.
4.1 Variable heat output.
N.B.: the pressures indicated in the tables represent the dierence
in existing pressures between the gas valve outlet and the com-
bustion chamber. e adjustments should therefore,be carried
out using a dierential 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 pressure
test. e power data given in the table is obtained with 0.5m long
intake/exhaust pipe. Gas ow rates refer to heating power below a
temperature of 15°C and pressure of 1013 mbar. Burner pressure
values refer to use of gas at 15°C.
