Making boiler ready for operation

STOP! First read the safety instructions on page 18 of these
instructions.
1. If the boiler is not commissioned directly after the installation:
carry out another leak test ( page 18). 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.
Commission the heating system with AquaSmart
The boiler is fully functional with the factory-installed AquaSmart
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).
