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 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 total water volume each month.

HINTS ON COMBUSTION

1. NOZZLES — Although the nozzle is a relatively

inexpensive device, its function is critical to the

successful operation of the oil burner. The selection

of the nozzle supplied with the CL boiler is the

result of extensive testing to obtain the best flame

shape and efficient combustion. Other brands of the

same spray angle and spray pattern may be used but

may not perform at the expected level of CO

and

smoke. Nozzles are delicate and should be protected

from dirt and abuse. Nozzles are mass-produced

and can vary from sample to sample. For all of

those reasons a spare nozzle is a desirable item for a

serviceman to have.

2. FUEL LEAKS — Any fuel leak between the

pump and the nozzle will be detrimental to good

combustion results. Look for wet surfaces in the air

tube, under the ignitor, and around the air inlet. Any

such leaks should be repaired as they may cause

erratic burning of the fuel and in the extreme case

may become a fire hazard.

3. AIR LEAKS — Any such leaks should be repaired,

as they may cause erratic burning of the fuel and in

extreme cases may become a fire hazard.
