Using Soot Blowers.

When using soot blowers care must be taken to ensure that the system is properly drained of water.
To start begin by draining the system as follows. Start with the rear Soot blowers. Open the drain cock and crack the Soot blower isolating valve, leave for approximately 20 minutes for the system to drain properly and to heat up, once you are satisfied that the system is properly drained and heated up close the drain cock and open the isolating valve fully.
Each Soot blower should have an isolating valve which must now be opened starting with No 1 valve , next turn the Soot blower handle to the full open position then immediately turn back to the fully closed position. Do this three times taking a total of 45 seconds for the whole process. Now proceed to Soot blower No 2 and repeat the process. Do the same for Soot blower No 3. Make sure the Soot blowers are in the fully closed position when you have finished blowing the tubes .Once finished close the isolating valve and open the drain cock.
Proceed to the front Soot blowers making sure to only do one Soot blower at a time . The front Soot blower drain cock must be opened and the isolating valve must be cracked, when the system is hot and drained close the drain cock and open the isolating valve fully then open and close the quick release valve three times occupying a total of 45 seconds .Close the isolating valve and open the drain cock fully.
If the boiler is not fully automatic the dampers will have to be adjusted accordingly to compensate for the disturbed draft . Close the front dampers slightly to prevent pressurizing the combustion chamber . When you have completed Soot blowing don’t forget to reset the front dampers so that you once more have a balanced draft .
Last check that all the isolating valves are closed and the drain valves are open .
