Air in pipes
Important: A central heating system can not operate correctly
unless it is filled with water and air bled from the system. If these
conditions are not met the system may be noisy.
Bleed the air in the radiators and adjust the pressure if system
requires. If the system requires filling to often this may be due
to minor leaks or corrosion in the system.
Note: Isolating valves are shown in the: OFF position
• Turn the switch ON ( I )
