Part 10 - Lighting the appliance / First start-up
Step 1: Turn power on and de-air cycle
Warning
Be careful when venting. The water can be hot. Use a cloth to collect spilled water.
Make sure that the system is properly vented. This will avoid noise and comfort problems. The CH pump has an
automatic vent and does not need venting.
To vent the system sufficiently, both the automatic air vent cycle of the appliance and separate venting of the
radiators must be performed using the following three steps.
1: Ensure all zones have outside the boiler have been vented and all air is out of the zones. Then plug in the
boiler to start the automatic air vent cycle. It is 5 minutes long and the LCD screen will start a
countdown from 5 minutes. During this time you will hear the pump moving and the three way valve moving
position in order to get as much air out of the boiler as possible.
The boiler must be manually bled of air using the manual air bleed on top of the heat exchanger. Before
commissioning and during the 5 minute air vent cycle, connect a silicone tube to the manual air bleed at front of the
heat exchanger. Lead it into a bucket and turn it until water pours out (3-4 full turns). Than flush the system with the
air bleed open for about 2 minutes, you will need to simultaneously be adding water to the system to account for the
water and air being deleted via the air vent. The automatic air vent cycle can be activated by unplugging, wait 30
seconds, and plugging back in the supply cable.
After approximately 5 minutes the air vent cycle is finished. Disconnect your tube and close the manual air vent.
To be sure all air is purged out of the total system subsequently bleed air in all zones in the system separately.
2: Repeat the automatic air vent cycle as described in step 1 if lots of air remains in the system.
Warning
Always vent the system after installation or maintenance activities on the CH system!
Caution
In case an air handler is installed in the CH system, installation of a secondary air vent between the air handler and
the appliance is strongly recommended.
Notice
Check the water pressure in the appliance after venting.
Refill the system when the water pressure is below 1 bar (14,5 psi).
Step 2: Perform calibration on the boiler via Auto or Manual Calibration
Calibration
Before the first start up of the appliance (before calibration) check the gas type setting is set correctly (parameter 15,
Table 10.1 Setting parameters). The
boiler is gas-adaptive, which means that the combination ionisation
electrode and the burner pneumatically and electronically control the CO2 percentage. During calibration, the start
current and the correct settings for the CO2 percentage are determined. During the manual calibration the
percentage can be adjusted if necessary. If at high altitude, above 2000ft elevation, we recommend manual
calibration. Otherwise auto calibration should suffice. If you want 100% accuracy, do manual calibration. Both
options are detailed below.
