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

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.

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.

C.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 CO2 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.
