Open the screw plug on the testing nipple for the gas inlet
pressure by 2 turns (fig. 57, pos. 1).
Reset the digital pressure gauge to "0".
NOTICE
Throughout the measuring operation, keep the
digital pressure gauge in the same position
(horizontal or vertical) in which it was reset
to "0".
Connect the pressure gauge connection tube to the posi-
tive port of the testing nipple (fig. 57, pos. 2).
Slowly open the gas valve by pushing on the gas valve
and turning it ¼ rotation in an counterclockwise direction
(fig. 54, page 49). The gas valve is open when it is in the
vertical position.
Switch ON the heating system by pressing the main
switch of the BC10 basic controller (fig. 58, pos. 1).
Press and hold the "Chimney sweep" button (fig. 58,
pos. 3) (approx. two seconds), until the dot in the right-
hand bottom corner of the display (fig. 58, pos. 9)
appears. See also table 8, "Flue gas test", page 41.
After the LED "Burner operation" (fig. 58, pos. 6) has lit
up wait for one minute until the boiler is burning at full
load.
Measure the gas supply pressure and enter it in the start-
up report, page 85.
The gas supply pressure must be:
– for natural gas min. 7 inch W.C. (17.4 mbar),
max. 10.5 inch W.C. (26.1 mbar), nominal supply pres-
sure 8 inch W.C. (19.9 mbar).
– for LPG min. 8 inch W.C. (19.9 mbar),
max. 13 inch W.C. (32.3 mbar), nominal supply pres-
sure 11 inch W.C. (27.4 mbar).
Press the "Service" button (fig. 58, pos. 4) repeatedly
until the temperature reading is shown in the display.
Press the "Chimney sweep" button (fig. 58, pos. 3) to
clear the reading. Also see table 8, "Flue gas test",
page 41
