pressure and as specified by the local codes as follows:
z Close valve at supply connection (Î page 15).
z Close open connections with blank plugs.
z Disconnect the expansion tank from the system by
closing the cap valve.
z Open mixing and stop valves on hot water side.
z Fill boiler slowly with water from the building
connection.
z Turn cap of automatic vent one revolution to allow the
air to escape.
z Slowly fill heating system. Observe pressure display
on pressure gauge during this process.
z Check connections and pipes for leaks.
z Bleed heating system through the bleed valves on
the radiators.
