at the place of connection.
- If there is a risk of dirt near the network, fit a gas filter
upstream of the connection.
- Vent the gas pipe and carefully check that all external and
internal boiler pipes are gas tight.
- Check the installation’s gas pressure.
- Check the gas pressure and consumption when commissioning
the appliance.
