How to un-bank a Boiler

At the I D damper control, open the damper fully to create a slight draft in the combustion chamber.
Open the guillotine door to the 200mm mark on the indicator plate, rake open the fire and spread fresh coal over the live coals after opening and closing the coal cut off door, dropping fresh coal onto the front of the stoker. Spread the coal evenly over the width of the stoker making sure that the live coal / fire is under the ignition arch and just behind the guillotine door.
Close the guillotine door to 100 to 120mm above the grate and open the coal cut off door.
At the I D fan control close the ID fan damper and make sure that the FD dampers are closed.
At the panel start the ID fan, then the FD fan/s keeping the stokers in the off position.
When you have ignition start the stokers and check that the fire does not move out from under the ignition arch, if necessary stop the stoker until ignition has been regained.
Once you are satisfied that you have ignition, start opening the dampers, starting with the ID damper and then the FD dampers to prevent a pressure build up in the combustion chamber, maintaining a balanced draft of -3pa on the draft gauge.
Remember to check the water level in the boiler and top up with water if necessary.
