testing with 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 of the washout chemical (caustic soda), if necessary, to bring the pH within the specified range.

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

2.WATER BOILERS

a.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 12 psi. To insure that the system is full, water should come out of all air vents when opened.

b.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.

i.Remove relief valve using extreme care to avoid damaging it.

ii.Add an appropriate amount of recommended boil out compound.

iii.Replace relief valve.

iv.Fill the entire system with water.

v.Start firing the boiler.

vi.Circulate the water through the entire system.

vii.Vent the system, including the radiation.

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

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

x.Stop firing the boiler.

xi.Drain the system in a manner and to a location that hot water can be discharged with safety.

xii.Remove plugs from all available returns and wash the water side of the boiler as thoroughly as possible, using a high- pressure water stream.

xiii.Refill the system with fresh water.

c.Add appropriate boiler water treatment compounds as recommended by your qualified water treatment company.

d.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 same manner as litmus paper, except it gives specific 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 specified range. With this lower level of protection, care must be exercised to eliminate all of the free oxygen in the system.

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

C. FREQUENT WATER ADDITION

NOTICE

IF, DURING NORMAL OPERATION, IT IS NECESSARY TO ADD MORE WATER PER MONTH THAN INDICATED BELOW, CONSULT A QUALIFIED SERVICE TECHNICIAN TO CHECK YOUR SYSTEM FOR LEAKS.

	EXCESSIVE WATER ADDITION:
		(Gal/Month)
V83:	6	V85:	9½	V87:	13	V89: 16
V84:	8	V86:	11	V88:	14½

A leaky system will increase the volume of make-up water supplied to the boiler which can significantly shorten the life of the boiler. Entrained in make-up water are dissolved minerals and oxygen. When the fresh, cool make-up water is heated in the boiler the minerals fall out as sediment and the oxygen escapes as a gas. Both can result in reduced boiler life. The accumulation of sediment can eventually isolate the water from contacting the cast iron. When this happens the cast iron in that area gets extremely hot and eventually cracks. The presence of free oxygen in the boiler creates a corrosive atmosphere which, if the concentration becomes high enough, can corrode the cast iron through from the inside. Since neither of these failure types are the result of a casting defect the warranty does not apply. Clearly it is in everyone’s best interest to prevent this type of failure. The maintenance of system integrity is the best method to achieve this.

D.ATTENTION TO BOILER WHILE NOT IN OPERATION.

NOTICE

If boiler is not used during winter time, it must be fully drained to prevent freez e damage.
