2 Safety instructions and
recommendations
2.1 Safety instructions
CAUTION
Before any work, switch off the mains supply to the
appliance.
CAUTION
In order to limit the risk of being scalded, the installation of
a thermostatic mixing valve on the domestic hot water flow
piping is compulsory.
2.2 Recommendations
CAUTION
Do not neglect to service the appliance. Service the
appliance regularly to ensure that it operates correctly.
WARNING
Only qualified professionals are authorised to work on the
appliance and the instalation.
WARNING
Heating water and domestic water must not come into

3 Technical description
3.1 General description
BL 150...500 are high performance independent domestic hot water
tanks.
DHW calorifiers BL 150...500 can be connected to central heating
boilers used for heating domestic hot water.
Main parts:
4The tanks are made of high quality steel lined with food quality
standard enamel vitrified at 850°C, which protects the tank from
corrosion.
4The heat exchanger welded into the tank is made of smooth
tubing, the external surface of which, which is in contact with
domestic water, is enamelled.
4The appliance is insulated by CFC-free polyurethane foam, which
reduces heat losses to a minimum
4The insulating material can be easily detached from the tank. This
measure facilitates the recycling of materials.
4The tank is protected against corrosion by a magnesium anode
which should be checked every 2 years and replaced if need be.
The tanks with the greatest capacity (BL 300, BL 400, BL 500) are
fitted with 2 protection anodes.
