Burnham V9A manual Boiler and System Cleaning Water Boilers

d.Stop burner and drain boiler in a manner and to a location that hot water can be discharged with safety.

e.Refill boiler to normal water line. If water in gauge glass does not appear to be clear, repeat steps (a. thru e.), and boil out the boiler for a longer time.

2.Low pressure steam boilers such as the V9A Series should be maintained with appropriate water treatment compounds. After cleaning process has been completed, add water treatment compounds as recommended by your local qualified water treatment company.

3.Remove temporary surface blowoff piping and replug tapping. Boil or bring water temperature to 180°F promptly in order to drive off the dissolved gases in the fresh water.

4.If unsteady water line, foaming or priming persist, install gate valve in Hartford Loop and drain valves in return main and at boiler and proceed as follows:

a.Connect hoses from drain cocks to floor drain.

Close gate valve in Hartford Loop and open drain valve in return main. Fill boiler to normal water level, turn on burner and operate boiler at this water level for at least 30 minutes after the condensate begins to run hot, then turn off burner.

Close all radiator valves. Remove all supply main air valves and plug the openings in supply main.

b.Draw about 5 gallons of hot water from boiler into a container and dissolve into it appropriate amount of a recommended boilout compound. Remove surface blowoff plug and pour this solution into boiler, then reinstall plug.

c.Turn on burner and keep operating while feeding water to boiler slowly. This will raise water level in boiler slowly so that water will be boiling hot and will rise slowly into supply main and back through return main, flowing from drain hose

at about 180°F. 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 cocks 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.

5.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 hydrion paper which is used in the same manner as litmus paper, except 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 higher than 7, but lower than 11. Add some appropriate water treatment chemicals, if necessary to bring the pH within the specified range.

6.Boiler is now ready to be put into service.

G.BOILER AND SYSTEM CLEANING - Water Boilers

1.Filling of Boiler and System --- General --- In a hot water heating system, the boiler and entire system (other than the expansion tank) must be full of water for satisfactory operation. Water should be added to the system until the boiler pressure gauge registers normal system design operating pressure. To insure that the system is full, water should come out of all air vents when opened.

2.Boiling Out of Boiler and System. The oil and grease which accumulate in a new hot water boiler can be washed out in the following manner.

a.Remove safety relief valve using extreme care to avoid damaging it.

b.Add an appropriate amount of recommended boilout compound.

c.Reinstall safety relief valve.

d.Fill the entire system with water.

e.Start firing the boiler.

f.Circulate the water through the entire system.

g.Vent the system, including the radiation.

h.Allow boiler water to reach operating temperature, if possible.

i.Continue to circulate the water for a few hours.

j.Stop firing the boiler.
