7.2 Commissioning
Before operating the appliance, the following should be done:
- Switch off the electrical power supply of the appliance
- Remove the case. This consists of the double front plate and the side plates.
Unscrew the 8 screws on the top and bottom. The casing can then be removed in one operation.
- Check the leak-tightness of the gas connection
- Check whether the electrical connection and the earthing have been properly done.
Also check whether the phase (L) has been connected properly. The boiler is phase sensitive.
- Twist open the cap of the automatic air vent.
- Fill the appliance and the system with water.
- Fill the condensate bottle trap with water. The beaker on the bottom can be easily unscrewed
and fi lled.
- Check the fl ue gas discharge connection and, if present, the air supply connection.
- Open the gas valve and vent the gas pipe.
- Switch on the electrical power supply of the appliance.
- Check the built in pump.
- Check the boiler at full load.
Start the boiler. Allow the boiler to run at full load and stabilise (around 3 minutes). At full load,
the following settings should be checked and corrected if necessary:
Reference value for full load
Reference value for CO
2
Types R30/45, R30/65, R30/85 and R30/120 8.8% ± 0.2 for natural gas G20, G25
9.8% ± 0.2 for propane G31
Type R30/100 9.4% ± 0.2 for natural gas G20, G25
10.4% ± 0.2 for propane G31
Reference value for CO
Types R30/45, R30/65 and R30/85
‹ 50 ppm for natural gas G20, G25
‹ 70 ppm for propane G31
Types R30/100 and R30/120 ‹ 75 ppm for natural gas G20, G25
‹ 100 ppm for propane G31
Measure the gas pressure before the gas valve. At full load, this must be at least 17 mbar for
natural gas and 30 mbar for propane. If there are several boilers, this pressure should be meas-
ured with all the boilers operating at full load.
Check the water-side temperature difference (∆t) between the fl ow and return connections of
the boiler. The ∆t should be between 15 and 25 K at full load.
- Check the boiler at minimum load.
Set the boiler back to minimum load. At minimum load, the following settings should be
checked and corrected if necessary:
Reference value for minimum load
Reference value for CO
