TECHNICAL DATA.

4.1

VARIABLE HEAT OUTPUT.

N.B.: the pressures indicated in the tables represent the difference
in existing pressures between the gas valve outlet and the com-
bustion chamber. The adjustments should therefore,be carried
out using a differential 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. The power data given in the table is obtained with 0.5m long
intake/exhaust pipe. Gas flow 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.
