The generator is started up as follows:
- check that the wording "RDY" appears on the display: if "OFF" appears, click the button under "FUN" and set the
equipment to "ON";
- on the LCD display check that the value in "Tin" is greater than the value in "Von".
- As soon as "ON" appears on the LCD display, the generator starts the ignition cycle;
- the ignition spark is output after the pre-washing time. After three consecutive unsuccessful ignition attempts,
the device gets blocked. Ten seconds must elapse before the device can be unblocked by resetting the burner
control equipment;
- the burner ignites after opening the gas solenoid valve;
- wait until the work conditions have stabilised (it takes approx. 15 minutes), after which examine combustion and
measure performances;
- check that the safety thermostat (Tso) causes the burner to get de-ignited.
6.9.3.1 Setting the bypass damper in the generator
A bypass damper is fitted in the unit with the purpose of controlling correct calibration of the air flow through the hot
air generator.
The flow rate through the bypass damper can be adjusted with the help of the moving sheet metal behind the unit:
this is moved to either increase or reduce the clearance of the bypass hole.
If the hole clearance is reduced, a greater amount of air flows through the generator and the head losses increase on
the air side; if the hole clearance is increased, a smaller amount of air flows through the generator, which consequently
leads to a reduction in the head losses on the air side.
Access to the moving metal sheet requires the removal of the fixed panel installed in the generator section.
