boiler" [ 204]. Static pressure MUST be 20 mbar (+ or – 1 mbar). If the
working pressure is <19 mbar, the gas boiler output will be reduced and the
correct combustion reading may NOT be obtained. Do NOT adjust the air and/
or gas ratio. To obtain sufficient working pressure, gas supply MUST be
correct.
INFORMATION
Make sure the working inlet pressure does NOT interfere with other gas appliances
installed.
The gas boiler has a test run function. Activating this function results in the
activation of the indoor unit pump, as well as the gas boiler (with a fixed fan
speed), without the control functions being actuated. The safety functions remain
active. The test run can be stopped by pressing
automatically after 10 minutes. To perform a test run, switch off the system with
the user interface.
