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, owing 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

ows 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 sufciently

(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 tting 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

relling 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 ow 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

re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

TDS: < 3500 ppm

same manner as litmus paper, except that it gives

specic 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 specied

range. With this lower level of protection, care must

be exercised to eliminate all of the free oxygen in

the system.
