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.  

VII:  MAINTENANCE AND SERVICE INSTRUCTIONS (continued)

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. 

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

3.  EXCESSIVE MAKE-UP WATER
  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, salts and oxygen. 

When the fresh, cool make-up water is heated in the 

boiler, the minerals fall out as sediment, the salts 

coat the inside of the boiler, and the oxygen escapes 

as a gas. The accumulation of sediment eventually 

isolates 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 or chloride salts in the boiler 

corrodes the cast iron from the inside. More make-

up water and higher concentrations of contaminants 

damage the boiler sooner.  

Our warranty does not 

cover corrosion and sediment-related damage.

Clearly it is in everyone’s best interest to prevent 

this type of failure. You can do your part by ensuring 

that your system is leak-free, keeping leakage to 

less than 2 percent of the boiler water volume each 

month.

IMPORTANT

IF,  DURING  NORMAL  OPERATION,  IT  IS 

NECESSARY  TO  ADD  MORE  WATER  THAN 

INDICATED  BELOW,  CONSULT A  qUALIFIED 

SERVICE  TECHNICIAN  TO  CHECK  YOUR 

SYSTEM  FOR  LEAKS.
