Making boiler ready for operation
STOP! Before commissioning:
▶ Carefully read the safety instructions in Chapter 6.3, page 21.
1. If the boiler is not commissioned directly after the installation:
Carry out another leak test (
page 21). Wait five (5) minutes until
all gas has dissipated. Then check whether there is any smell of gas
(including at floor level).
If you smell gas: STOP! Seal leaks and repeat the leak test
(
page 21).
If you do not smell gas, go to the next step.
2. Open the gas shutoff valve.
