Hydraulic characteristics
The boiler is supplied as standard with an automatic by-pass and a 2-speed
ciculator. The diagram (fig. 4) shows the curve of the pressure available as a
function of the flow (at the boiler outlet). The minimum flow rate of the
installation to ensure proper operation must be 300 l/h. (Thermostatic taps
closed).
Water capacity of the installation. The boiler is fitted with a pressurized
expansion vessel. Maximum volume of the expansion tank: 7.1 litres. Inflation
pressure: 0.7 bar.
The expansion capacity of the vessel of a pressurized installation varies with
(fig. 5): the average operating temperature in °C, – the static height which
corresponds to the difference in level in meters, between the highest point
top of the installation and the axis of the expansion tank
The filling pressure should always be higher than the static height (expressed
in meters) divided by 10 (recommended between 1 and 1.5 bars)

4.2 PRECONISATION D’INSTALLATION
Installation of the boiler – the axis of the external flue must be placed at a
distance of
at least 0.40 m from any opening window and at a minimum distance of 0.60 m
from any ventilation orifice (depending on the type of outlet chosen, refer to
the instructions for the evacuation kit). – when installing a boiler in a
bathroom, comply with the special safety rules of standard NF C 15-100
(chapter 7).
– do not install the boiler above the hotplates, the oven, and in general
above any equipment producing oily vapors which could, through clogging,
affect its operation.
– provide a wall and fixings to support the weight of the boiler (weight:
approximately 130 kg). – take precautions to limit
noise pollution.
Domestic hot water circuit
In the case of water hardness greater than TH 25, provide water treatment.
See sanitary DTU standard .
Central heating circuit Flow rate: when sizing, make sure that the minimum
flow rate is complied with: 300 I/h, thermostatic valves closed.
Corrosion Precautions
Operating incidents due to corrosion are likely to occur when the installation
is made with dissimilar elements.
To avoid these problems it is desirable to use a corrosion inhibitor. Take
every precaution to prevent the treated water from becoming aggressive. Old
installation: place a settling pot on the return and at the low point, and
provide for appropriate treatment of the circuit.
Recommendation: provide air vents on all the radiators and at the high points
of the installation; as well as drain cocks at low points.
Heating, ventilation, refrigeration, air conditioning and production of steam
and domestic hot water. b) Specific
requirements for each type of establishment open to the public (hospitals,
shops, etc.). Recommendation :
If the region is exposed to the risk of lightning (insulated installation at
the end of the EDF line, etc.), provide a lightning arrester.
Our warranty is subject to this condition.

Practical advice
Frost Precautions
We advise you to consult your installer or your after-sales service who will
tell you which measures are best suited to your situation. · Sanitary circuit
The boiler’s sanitary circuit is drained after having closed the
installation’s cold water tap at the water meter, then: – open a hot water
tap, – activate the drain valve of the balloon valve 38 (fig. 18). Water flows
out of the drain hole. · Heating circuit Take one of the following measures: –
- Drain the circuit of the heating installation – 2) Protect the heating installation with an antifreeze product. Periodic verification of the level of protection provided by this antifreeze is an additional guarantee.
– 3) Let your installation run at idle speed by setting the room thermostat to the “frost protection” position (between 5 and 10°C). Caution: leave the boiler in the heating position
