recommended boil out compound.

iii. Replace safety 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 thru 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.

O. 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 V7 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.FLAME SHAPE — Looking into the combustion chamber through the observation door, the flame should appear straight with no sparklers rolling up toward the crown of the chamber. If the flame drags to the right or left, sends sparklers upward or makes wet spots on the target wall, the nozzle should be replaced. If the condition persists look for fuel leaks, air leaks, water or dirt in the fuel as described above.

3.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.

4.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.

5.GASKET LEAKS — If 11.5 to 12.5% CO2 with a #1 smoke cannot be obtained in the breeching, look

for air leaks around the burner mounting gasket, observation door, and canopy gasket. Such air leaks

will cause a lower CO2 reading in the breeching. The smaller the firing rate the greater effect an air leak can have on CO2 readings.

6.DIRT — A fuel filter is a good investment. Accidental accumulation of dirt in the fuel system can clog the nozzle or nozzle strainer and produce a poor spray pattern from the nozzle. The smaller the firing rate, the smaller the slots become in the nozzle and the more prone to plugging it becomes with the same amount of dirt.

7.WATER — Water in the fuel in large amounts will stall the fuel pump. Water in the fuel in smaller amounts will cause excessive wear on the pump, but more importantly water doesn’t burn. It chills the flame and causes smoke and unburned fuel to pass out of the combustion chamber and clog the flueways of the boiler.

8.COLD OIL — If the oil temperature approaching the fuel pump is 40°F or lower poor combustion or delayed ignition may result. Cold oil is harder to atomize at the nozzle. Thus, the spray droplets get larger and the flame shape gets longer. An outside fuel tank that is above grade or has fuel lines in a shallow bury is a good candidate for cold oil. The best solution is to bury the tank and lines deep enough to keep the oil above 40°F.

9.HIGH ALTITUDE INSTALLATIONS

Air openings must be increased at higher altitudes. Use instruments and set for 11.5 to 12.5% CO2.
