CONDITIONED CONFIGURATIONS (sub-
ject to assessment).
•
Installation in unheated room, with 1 duct
only (volume > 20 m
3
) (Fig. 3-4).
FAN Parameter
set on
1
(Parag. 3.6).
Possible consequence:
- In the event of installation with air intake in
the installation room and expulsion through
duct, the ventilation openings must be sized
according to the provisions of the regulations
in force.
Attention:
in winter, the intake air will be colder
than that discharged by the water heater, which
will increase garage cooling.
FORBIDDEN CONFIGURATIONS.
Installation configurations forbidden Associated risk
Water heater drawing air from a room containing
a paid-for heat source intended to heat the room.
Excessive system consumption: the water heater no longer uses free calories, but those
produced by other appliances connected to other energy sources.
Connection to controlled mechanical ventilation
system (CMV).
The air flow rates in the thermodynamic water heater (around 300 m
3
/h) are incompatible
with those of a CMV (around 100 m
3
/h).
Furthermore, the CMV ducts may convey greasy vapour and dust, potentially harmful for
the duration in service of your water heater.
Connection to an attic.
If there is inadequate insulation between the building and its attics, this type of installation
could increase the heat loss from the building.
In extreme cases, condensate might form on the ceilings of the rooms under the attic due
to its cooling.
There is a greater risk from falling objects and dust ingress to the water-heater in this
configuration, which could reduce its life expectancy.
duct which takes air from the outside, conveying
cold air inside.
Significant loss of performance coefficient PCO and much greater cooling of the room.
Connection to a geo-thermal system.
Excessive loss of load, and problems balancing the two fans in series.
Significant risk of clogging on the evaporator.
Other prohibitions:
- Do not connect the device's fan to a tum-
ble-dryer
- Avoid very dusty rooms
- Do not extract air containing solvents or ex-
plosive materials
- Do not connect the appliance to a suction hood
used to extract greasy or polluted air
- Do not install the water heater in a room ex-
posed to frost
- Do not place any objects on the water heater
- In non-ducted or semi-ducted configuration,
do not place it in a room where an open cham-
ber heat generator is installed (type B).
