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

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.
1 – Suction feed
2 – Return
3 – Choke
4 – Pressure control
N.B. If the vacuum exceeds 4 m., 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
decreases and if the volume of air is decreased, the level of CO
12%.
- 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 condensation 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 prob-
lem. 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 adher
ence to different parameters. The burners are designed for conformity to the most rigid international
regulations for energy conservation and respect for the environment.
