15) Broken draught regulator
16) Auxiliary niche for burning air
17) Very high temperature of the burnt gases (very strong draught or boiler too little
for covering the heating needs)
18) Very low temperature of the burnt gases (evident functioning under the boiler
parameters, boiler bigger than the heating needs).
19) Fuel with a lot of humidity (with a low calorific power).
7. CONTROL PANEL
7.1 GENERAL CARACTERISTICS
The boiler control panel includes all the connections and measurement instruments needed
for controlling the boiler and its good functioning.
All the electrical connections in the panel are made by the producer. The installation of the
panel and the probes of the measurement instruments.
The instruments (thermometer, thermostats and safety thermostat) have brass probes to read
the water temperature in the boiler. In order to a better transmission of the parameters there
must be a nonvolatile liquid (oil) in the special place for them in the boiler.
a) the thermometer shows the instant temperature from the boiler at the above part of the
water chamber.
b) the burner thermostat switches off the burner when the temperature reaches the desired
level. It is recommended that the water temperature should not be less than 65 C. The
recommended temperature is between 70-90 C.
c) the pump thermostat is responsible with its starting. The starting temperature of it is
normally between 40-45 C.
d) the safety thermostat activates when the water reaches the maximal temperature, it
switches off immediately the burner. So the risk of vaporizing of the water at temperatures
above 90 C is avoided. For the system to restart its function we must wait for about 5
minutes, while the pump will remain working and the boiler temperature will drop under 90
C. After the temperature drops press the reset button of the safety thermostat in order for the
system to restart working..
e). The ON-OFF button is used for electric feeding of the panel. It is used by the operator for
maintenance and repairs of the boiler.
g) the witness lamps are lit during burner or pump operation.
f) the instrument probes must be well fitted inside the sheath and have a safety clip. Install the
extra length of the capillary tubes on the insulation on the boiler body and do not bend the
capillary (they can be damaged)
When installing a burner it is compulsory that the mounting and connecting of the burner to
the control panel to be made by an authorized installation company. The operation of the
burner and its signals are described in its technical book. An authorised electrician must make
the electric conexion to the control panel by the drawing provided.
7.2 Electric installation
An authorized electrician according with the valid rules EN 60529 and EN 60335-1, and the
protection rules IP 40 and IP 44 must realize the electric installation. the electric installation of
the boiler consists on an general electric panel placed on the wall which distributes the
electric power needed.
This must be waterproof, and the wires must be insulated. The light and the light switch
should be on a separate circuit. The light lamps must be placed on the ceiling and waterproof.
The wires must be protected until maximum 16 A.
