2. Starting the Burner From Cold
a) Fill the boiler as described in Section 1.
b) SHUT the main steam valve.
c) Open all the valves in the gas train/oil supply. It is assured that the fuel supply

carried out to check the functions of all the safety interlocks. For more
detailed information on the burner firing sequence consult the burner
