to drive off any dissolved gases, which might otherwise
corrode the metal.
The above procedure may be omitted in the case of a unit previously used or known to be internally
clean. However, consideration must be given to the possibility of contaminating materials entering the
boiler from the system.
On a steam system, the condensate should be wasted until tests show the elimination of undesirable
impurities. During the period that condensate is wasted, be sure make-up water is treated to prevent
an accumulation of unwanted materials or corrosion.
Washing Out
No later than three months after initially placing the boiler into operation and starting service, and
thereafter as conditions warrant, the pressure vessel should be drained after being properly cooled to
near ambient temperature. Hand-hole covers should be removed and waterside surfaces should be
inspected for corrosion, pitting, or formation of deposits.
Flushing of Pressure Vessel Interior
Upon completion of the inspection, the pressure vessel interior should be flushed out, as required,
with a high pressure hose. If deposits are not fully removed by flushing, a consultation may be
required with your local authorized boiler representative. In extreme cases, it may be necessary to
resort to acid cleaning. Professional advice is recommended if acid cleaning is required.
The inspections will indicate the effectiveness of the feed-water treatment. The effectiveness of
treatment, the water conditions, and the amount of fresh water make-up required are all factors to be
considered in establishing frequency of future pressure vessel washouts. Contact your local
authorized boiler representative for more information.
