Pump Pressure Adjustment; Combustion Control - Lamborghini Caloreclima ECO 50/2 Manual Para La Instalacion Y El Mantenimento

PUMP PRESSURE ADJUSTMENT

The pump is pre-set at 12 bar.
To control the pressure, use the oil pressure gauge.
Normally, the pressure is set between 11 and 15 bar.

utilise a circulation pump

COMBUSTION CONTROL

In order to obtain optimum combustion efficiency, also with respect to the environment, it is advisable to use the appropriate
instruments when controlling or regulating combustion. The fundamental levels to consider are:
- CO Indicates the volume of air used in combustion; if air volume is increased, the level of CO
2
volume of air is decreased, the level of CO
- Smoke emissions control (Bacharach). It is important to note the presence of non-burned solid particles in smoke. If the
level of particles in the smoke exceeds n° 2 on the BH scale, the choke should be checked for defects and that it is the
proper choke for the burner and furnace (brand, type, angle of atomisation). Generally, the n° BH tends to diminish by
raising pump pressure; it is necessary in this case to control the amount of fuel flow, which will increase and therefore, it
may be necessary to reduce the capacity of the choke.
- Smoke temperature. This level represents the dispersion of heat through the chimney; the higher the temperature is, the
higher the dispersion of heat will be as well as a lower effective out-put from the combustion.
With the burners working at low or high flame, it is necessary to check that they do not create the conditions for condensa-
tion in the smoke, in the furnace or in the chimney. Condensation, which is typically acid, can provoke serious corrosion in
the furnace. Therefore, it is necessary to consult the manufacturer on this problem. Regarding the chimney, depending on
the material used in construction, corrosion, stains from humidity or difficulties in the dispersion of smoke can occur.
N.B.: Existing regulations in certain countries could differ from the stated values herein and require adherence to different
parameters. The burners are designed for conformity to the most rigid international regulations for energy conserva-
tion and respect for the environment.
