When you have completed all the installation make sure that all the air vents on the radiators are closed. Start filling the system with water and vent through each radiator. Check for leaks. Before turning the boiler on run the heating pump to ensure that as much air in the system is dislodged and then re-vent. Never vent the system while the pump is running. Then turn on the boiler and as the water warms up balance the water flow to each radiator using the lock shield valves.
Check all the controls and safety systems to ensure the system is working correctly.
Allow the system to run for a few days then check for any leaks and ensure the system is fully vented.
