5 Commissioning
5.1 Commissioning
1 Before commissioning the heater and putting it under voltage, ensure that the connectors are well
performed as described in the following chapters:
– Connecting the condensate, page 16;
– Connecting the flue, page 12-15;
– Electrical connection, page 18-21;
– Gas connection, page 17.
2 Also ensure that:
– The protective film on the panels has been removed;
– The distance around the unit has been met;
– All electrical connections are performed;
– That the ground connection is performed.
3 Check the power supply of the heater. This should be between 210V and 230V AC. Note the polarity
Neutral and Phase. In case of a two-stage network an isolating transformer should be applied. For more
information please ask the manufacturer.
4 Ensure that the type of gas and the gas pressure match the information on the type plate.
5 Ensure that the Comtherm or the communication with the heater operates.
6 Take the air heater into operation:
– Open the gas valve and purge it;
– Switch on the electrical supply;
– Ensure that the exhaust vanes are open at a minimum of 45°;
– Create heat demand by setting the room temperature control (Comtherm) to a value at least
1°C higher than the actual room temperature. Set the Comtherm to <auto> (see the manual of the
Comtherm);
– The heater starts.
Note: The units are pre-calibrated at the factory, though it may be necessary to correct the initial
adjustment values. This is particularly the case when the units are installed at a height higher than 500m.
Due to the lower air pressure, the combustion values may be affected. In addition, correction may be
necessary in case of different qualities of the local gas. For instruction, see page 25.
7 Set the Comtherm according to the manual.
In case of a fan with variable speed the minimum and maximum speeds should also be entered next to
the switching times and temperature settings. For the minimum speed a minimum value of 30 should be
entered and for the maximum speed a minimum value of 70 should be entered.
