Minimum Water Quality Requirements; Water Content - Burnham 5B Series Installation And Operation Manual

b. Draw about 5 gallons of hot water from
boiler into a container and dissolve into it the
appropriate amount of a recommended boilout
compound. Remove safety valve from boiler
and pour this solution into boiler, then reinstall
safety valve.
c. Turn on burner and keep operating while feeding
water to boiler slowly. This will raise water
level in boiler slowly into supply main and back
through return main, flowing from drain hose
at about 180ºF. Continue until water runs clear
from drain hose for at least 30 minutes.
d. Stop feeding water to boiler but continue
operating burner until excess water in boiler
flows out through supply main and water lowers
(by steaming) until it reaches normal level in
boiler.
Turn off burner. Drain boiler. Open all radiator
valves. Reinstall all supply main air valves.
Open gate valve in Hartford Loop.
e. When boiler has cooled down sufficiently
(crown-sheet of sections are not too hot to
touch), close the drain valves at boiler and in
return main and feed water slowly up to normal
level in boiler. Turn on burner and allow boiler
to steam for 10 minutes, then turn off burner.
Draw off one quart of water from bottom gauge
glass fitting and discard. Draw off another quart
sample and if this sample is not clear, repeat the
cycle of draining the boiler and return main and
refilling the boiler until sample is clear.
f. If the boiler water becomes dirty again at a later
date due to additional sediment loosened up in
the piping, close gate valve in Hartford Loop,
open drain valve in return main, turn on burner
and allow condensate to flow to drain until it has
run clear for at least 30 minutes while feeding
water to boiler so as to maintain normal water
level. Turn off burner, drain boiler, open gate
valve in Hartford Loop, then repeat step 1 above.
3. Make pH or Alkalinity Test
After boiler and system have been cleaned and
refilled 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
42
SecTiON iV - OPeRATiON (continued)
same manner as litmus paper, except that it gives
specific readings. A color chart on the side of
the small hydrion dispenser gives the reading in
pH. Hydrion paper is inexpensive and obtainable
from any chemical supply house or through your
local druggist. The pH should be in accordance
to "Minimum Water Quality Requirements" chart
below. Add some washout chemicals (caustic soda),
if necessary, to bring the pH within the specified
range. With this lower level of protection, care must
be exercised to eliminate all of the free oxygen in
the system.
4. Boiler is now ready to be put into service.
