Installation
DANGER: Explosion
▶ Always turn off the gas cock before
carrying out any work on components
which carry gas.
Installation, electrical connection, gas
installation, connection of inlet and exhaust
pipes and initial startup must be realized
exclusively by authorized personnel.
The appliance can only be sold in the countries
mentioned in the type plate.
The use of these heaters with water supply
pressure values below 0.5 bar is not
recommended.

Important information
▶ Before installing, call the gas company and check the
standard relating to gas heaters and ventilation
requirements for rooms.
▶ Install a gas cut-off valve as close as possible to the heater.
▶ After finishing the gas system, the pipes must be
thoroughly cleaned and leak-tested; to avoid damaging the
gas valve by excess pressure, this test must be performed
with the gas valve of the heater closed.
▶ Check if the heater corresponds to the type of gas
provided.
▶ Check if the flow and pressure through the installed
reducer are appropriate for the consumption of the heater
(see technical data in the table 5).

Selection of the place of installation
Requirements regarding the place of installation
•
Do not install the heater in rooms with a volume of less than
3
8 m
(not including the volume of the furniture providing
this does not exceed 2 m
•
Comply with the specific instructions for each country.
•
Assemble the gas heater in a well-ventilated location where
it will not be exposed to temperatures below zero and in a
place where there is an evacuation pipe for combustion
gases.
•
The gas heater must not be installed over a heat source.

.
•
To avoid corrosion, the combustion air must be free from
harmful substances. Examples of particularly corrosive
substances: halogenated hydrocarbons contained in
solvents, paints, glues, engine gases and various domestic
detergents. If necessary, take adequate measures.
•
Respect the minimum installation clearances indicated in
Fig. 10.
•
The heater must not be installed in locations where the
room temperature can reach 0 °C.
In case of a frost risk:
▶ Turn off the heater.
▶ Purge the heater (see section 3.6).

Minimum clearances
Combustion gases
•
All gas heaters must be connected in a leak-roof manner to
a gas evacuation pipe of adequate dimensions.
•
The flue must:
– be vertical (reduced horizontal sections or no
horizontal sections at all)
– be thermally insulated
– have an exit above the maximum roof level
•
The combustion gases evacuation pipe must be inserted in
the flue ring. The external diameter of the pipe must be
slightly less than the diameter of the flue indicated in the

•
The extremity of the evacuation pipe must be protected
against wind/rain.
