1.3 Instructions for use
-
Please read the instructions in this manual carefully for the operation and maintenance of this device.
-
Carry out maintenance at least once a year by qualified personnel. The frequency of the maintenance
operations depends on the environment in which the device is installed. More regular inspection must be
carried out in dusty locations.
-
Regularly check that device, the chimney or the gas pipe are not damaged.
-
Regularly check that air openings in the building and around the device are not obstructed.
-
Check that hot air circulates normally in the room, and therefore that there is no obstacle on the suction
side (fan side), and in front of the blowing side of the unit (check that the grille is well opened).
-
The control box must have a cut off electricity each 24 hours.
1.4 Operation
When heat is required (ambient temperature under thermostat setting temperature), the exhaust fan starts.
To avoid any gas into the combustion chamber, the exhaust fan ventilates during few seconds, then the
burner is igniting by the ignition sensor. When the heat exchanger is hot enough, the blowing fan starts. The
hot air is blown into the room.
When the setting temperature is reached, the burner is turned off. The fan continues to turn for about one
minute, until it has cooled the heat exchanger.
1.5 Safety
-
If there is no flame, this is detected by an ionisation sensor and the gas vales are immediately closed.
This default can be reset remotely or on the appliance.
-
The thermal protection of the heat exchanger is ensured by two thermostats. The first, which is
automatically reset, protects against insufficient air flow (obstructions, fan failure). The second, which has to
be manually reset, is set to a higher threshold than the first one. It protects the device against high excess
heating due to an operating problem or unsuitable use.
If the operation shows any difficulty whatsoever, please contact us.
Make sure that the device can be supplied normally with combustion air at atmospheric pressure (any
modification of the building after the installation of the device must be carried out taking this into account).
Excessively low pressure inside the room can harm the correct functioning of the device by depriving it of
the air necessary for combustion.
1.6 Cut-off
-
To cut off the appliance during a short period, it is necessary only to cut off the thermostatic line (this
means turning the thermostat to a minimum setting point or turning off the thermostat switch) .
-
For a prolonged stoppage, switch off the thermostatic line, close the gas valve and cut off the electrical
supply, taking care to wait for
the fan to stop running.
-
Gas and electricity must only be turn off in case of emergency or for long stoppage periods.
IMPORTANT : Never cut off the power supply while the gas heater is running or when the heat exchanger
is cold down. The non-compliance with these instructions may cause damage to the heat exchanger and
cause the loss of the warranty.
1.7 Control board
The appliance is equipped with an integrated control board for smart operating management. In case of any
unit failure, the board indicates the source of the problem and support the technician for troubleshooting.
