6.4 Making boiler ready for operation
STOP! First read the safety instructions on page 29 of
these instructions.
1. If the boiler is not commissioned directly after the
installation:
carry out another leak test (Æ page 28). Wait five (5)
minutes until all gas residues have dissipated. Finally
check whether there is any smell of gas, including at
floor level. If you smell gas, STOP! Seal leaks and
repeat the leak test.
If you do not smell gas, go to the next step.
2. Open the gas shut-off valve.
6.4.1 Commission the heating system with
aquastat control
The boiler is fully functional with the factory-installed
aquastat.
3. Switch on ON/OFF switch [1] (“ON” position). This
turns on the boiler with all its components.
4. Make sure that the room thermostat signals a heat
requirement (set thermostat at least 10 °F above room
temperature).

6.4.2 Placing heating system with Logamatic
2000 control unit in operation
The boiler is fully functional with the factory-installed
aquastat. A Logamatic 2000 control unit can be installed
in addition to the factory-installed aquastat.
Use the on/off switch on the control unit to switch the
heating system on. The burner starts operating if heat is
required (Æ observe control unit service manual).
5. Make sure that heat is required at the control. To do
this, select “Manual operation” operating mode (hand
symbol) with the mode selector switch [1].
6. Switch on ON/OFF switch [2] (“ON” position).
