c. Remove relief valve using extreme care to avoid
damaging it.
d. Add an appropriate amount of recommended boil
out compound.
e. Replace relief valve.
f. Fill the entire system with water.
g. Start fi ring the boiler.
h. Circulate the water through the entire system.
i. Vent the system, including the radiation.
j Allow boiler water to reach operating
temperature, if possible.
k. Continue to circulate the water for a few hours.
l. Stop fi ring the boiler.
m. Drain the system in a manner and to a location
that hot water can be discharged with safety.
n. Remove plugs from all available returns and
wash the water side of the boiler as thoroughly as
possible, using a high-pressure water stream.
o. Refi ll the system with fresh water.
3. Add appropriate boiler water treatment compounds
as recommended by your qualifi ed water treatment
company.
4. Make pH or Alkalinity Test.
After boiler and system have been cleaned and
refi lled as previously described, test the pH of
the water in the system. This can easily be done
by drawing a small sample of boiler water and
testing with hydrion paper which is used in the
same manner as litmus paper, except it gives
specifi c readings. A color chart on the side of the
small hydrion dispenser gives the reading pH.
Hydrion paper is inexpensive and obtainable from
any chemical supply house or through your local
druggist. The pH should be higher than 7 but lower
than 11. Add appropriate water treatment chemicals,
if necessary, to bring the pH within the specifi ed
range. With this lower level of protection, care must
be exercised to eliminate all of the free oxygen in
the system.
5. Boiler is now ready to be put into service.
C. FREQUENT WATER ADDITION
Although unusual for a water boiler, frequent water
additions are a sign of a leaky system. Excessive
amounts of make up water supplied to the boiler can
signifi cantly shorten the life of the boiler. The amount
of water varies with the contamination level of the
water. Repair the leak and consult with your water
treatment specialist for recommendations.
D. ATTENTION TO BOILER WHILE NOT IN
OPERATION.
