Turn on water to fill system, check for leaks regularly and bleed air from all points. Bleed the air from all the pumps in the system, and rotate the impeller shaft.
Check that all radiators valves are open, remove the thermostatic valve heads, fully open all lockshield valves.
Turn ON gas, bleed air out at the isolation valve union. Reseal and check for gas leaks. Turn gas OFF.
Turn electricity on at the power point. At the boiler front panel set the temperature setting to the lowest setting, switch boiler to ON position. The "Power on" Indicator should light. Turn the boiler off at the front panel.
