before it is placed in service it is advisable
to purge the pressure vessel of any oil
film,dirt, or other impurities. Clean the
pressure vessel as follows:
1. Isolate the boiler from the system by
shutting off the main steam valve.
2. Remove the steam safety valve.
3. Mix washing soda with water in a one-
gallon container and pour it into the
boiler through the steam safety valve
opening.
4. The mixture of washing soda to water is
as follows:

40, 50, 60 4 lb (1,814g)
80 5 lb (2270g)
100 7 lb (3178g)
130 9 lb (4080g)
150 10.5 lb (4760g)
5. Replace the steam safety valve.
6. Fill the boiler with water. Water level is
about center in the water gauge glass.
7. Generate 15 PSI (1.054 kg/cm
steam and shut off the boiler. Allow this
hot solution to remain in the boiler for 10
minutes.
8. Drain and flush the boiler twice with
fresh water.
9. To remove all the oil and dirt from the
main steam and the condensate return
lines, allow the returns to go into a floor
drain or a safe discharge point for the
first week of operation.
