Transport And Handling - BIEMMEDUE GA/N 70C Manual De Instrucciones

change the diffusion ring securing it in such a way that
the ignition electrode is equidistant between the two
subsequent holes;
• Calibrate the gas pressure switch (4) on the gas valve group
(Fig.4):
• Regulate the gas pressure switch to a value equal to 80%
the supply pressure;
• Regulate the pressure regulator for the gas valve group (Fig.4);
to the burner pressure stated in Tab. I.:
• Connect a gauge to the pressure intake (1) upstream and
a second gauge to the pressure intake downstream (2) of
the valve group;
• Start the heater and take the reading off the 1st supply
pressure gauge and if necessary adjust the pressure
regulator (3) for the gas supply system until the correct
supply pressure shown in Tab. I is reached;
• Take a reading off the 2nd working pressure gauge and if
necessary use a screwdriver to adjust the pressure of the
gas valve group (4) to restore the working pressure shown
in Tab. I
• Apply the adhesive label with the words "SET UP FOR ..."
corresponding to the type of fuel and the category chosen on
the gas valve group.
5. OPERATING INSTRUCTIONS
5.1 START-UP
To start the space heater (Fig. 1):
• Make sure the switch (9) is set to "0";
• Switch on power to the heater by means of the isolation switch
on the power switchboard;
• Preset the post-ventilation mode (the ventilation for cooling the
space heater when the flame is turned off) by setting
commutator (14) to position (0) for timed post-ventilation (90
sec after the flame goes out the fan stops as well) or to
position (I) for continuous post-ventilation (the fan works
continuously);
• Move the switch (9) to position (I);
• Operation will only be automatic if a thermostat or another
control device is connected to the thermostat plug (10).
• If after these operations, the generator does not work, refer to
the "FAULTS, CAUSES AND REMEDIES" section and find the
cause.
Warning
In case of safety stop, you have to push the reset button
(d) for 3 seconds to restart the heater.
Warning
NEVER do more than two restarts in a row: unburned fuel
can accumulate in the combustion chamber and suddenly
flare up at the next restart.
5.2 STOP
To stop operation turn the switch (9) to "0" if operation is manual,
or to room thermostat if operation is automatic.
Lastly, close the gas supply stopcock and turn off the isolation
switch.
The flame goes out and the fan motor will continue to run until
the combustion chamber has cooled down completely.
The flame goes out and the fan motor continues to work
according to the preset mode (timed post-ventilation or continuous
post-ventilation).

Warning
Never stop the heater by simply turning off the
disconnecting switch on the panel.
The electrical supply must be disconnected ONLY when
the fan has come to a complete stop.
5.3 VENTILATION
To obtain the ventilation effect only, simply turn the switch (14) to
the position marked with the symbol (I) to start the machine: the
main fan starts while the burner stays off.

6. TRANSPORT AND HANDLING

The space heater can be lifted up and suspended using the four
anchor hooks provided in the casing.
Warning
Before moving the unit:
• Stop the machine as indicated in the "STOP" paragraph;
• Disengage the power supply by removing the plug from
the power socket;
• Fully unscrew the fitting that connects the gas pipe to
the heater;
• Wait until the heater has cooled down.
Warning
During transportation and/or storage, make sure the gas
valve group and gas connection pipes are not knocked or
damaged in any way.
Warning
All of the operations described in this section must be
performed by professionally qualified personnel only.
The following procedures must be done at regular intervals to
ensure efficient operation of the heater. Make sure you have
detached the electrical power line from the heater before starting
any work.
Procedure
Check heater
Check gas supply line
Clean exterior of heater
Clean motor and fan
Check gas supply pressure
Check electrical connections
Check thermostats
Clean interior of heater
Inspect and clean
chamber
