1.7 Applications
The G series series hot air generators run on LPG (Liquid petroleum gas) and methane as the combustion fuel.
The G series generators are of direct combustion type. The air is heated by means of the thermal energy
generated during combustion and is transferred to the environment to be heated with the combustion products,
thereby rendering the thermal energy produced 100% available. The environment must be suitably ventilated in
order to ensure sufficient air exchange.
Do not use the generator in basements or below ground level or in premises destined for domestic use.
There are a series of safety devices which come into effect in the event of faulty function. The electronic control
device intervenes in the event of irregular flame or flame which tends to go out, stopping the burner and igniting
the burner block button indicator.
G56-70 and G56-100 stop if there is a fault in ventilation.
The materials used in building the machine ensure reliability and durability in time.
This device must be used only for the functions for which it was intended
- Hot air generator.
Any other use is to be considered improper and dangerous.

2.3 Electrical connection
The installation involves the use of a humidistat or a thermostat ON/OFF controlling the power
of the machine; it is still possible to use, alternatively, a switch ON/OFF, in this case the start
and stop of the machine must be done manually.
The choice, however, does not affect the installation procedure described below.
Electrical connections must be undertaken by specialized, experienced and trained
technicians, in accordance with the current legislation.
Ensure that the electricity supply specifications correspond to those indicated in the
in this manual.
It is obligatory that the device is grounded using an efficient ground line.
The installation must foresee a device enabled to disconnect the machine from the electric supply.
2.4 Gas supply connection
The G series generator comes complete with gas valve inside the machine’s electrical box.
The plug for the line connection is 1/2”.
The gas supply line’s pressure must be in compliance with the data indicated in the
following table;
Connect the supply tube to the pressure reducer, and the latter to the cylinder of LPG or
the CNG line;
Use a flexible tube with a maximum length of 2m and make sure that there are no
bottlenecks;
The system must be adapted to the characteristics of the equipment in use and comply
with the current regulations.
3 - OPERATION
3.1 Getting started
Before operating the generator, verify that:
1. All connections, both electrical and hydraulic, are made according to the instructions contained in this
manual;
2. The generator is free and clean;
3. The gas supply tap is open.
3.2 First start
- Check the correct air flow direction (Fig. 3.1);
- Make sure all wires are regularly placed and not caught or pulled by any object;
- Ensure that the gas connections are correct;
- Open the methane supply tap while making sure that there are no leaks along the load circuit
and that the pressure is in compliance with the technical specifications indicated in the tables.

the machine stops and a signaling light turns on.
If the flame is not detected, the machine makes 3 attempt to lit the burner, after that the machines stops
and a signaling light turns on.
If the thermostatic socket contact (1-2) becomes open, the machine stops, without signaling. When the
contact turns closed again the machine restart after doing the check sequence.
In order to reset the state of the machine, it is needed to hold the reset button for 2,5”, verify the malfunction
causes before (ventilation problems, no gas…).
The signaling light turns off and the start sequence is executed.
4 - MAINTENANCE
Before undertaking any maintenance,
disconnect the device from the
electricity and gas supply!
Periodically check the efficiency of the heating system and the correct functioning of the fan. Keep the machine
clean and prevent the accumulation of dirt. Periodically clean the internal grill and the generators’ body.
4.1 Cleaning
Periodically perform the following operations by ensuring that the machine is disconnected from the mains and
the gas supply is interrupted. Make sure the device is cold before cleaning.
To clean the internal parts remove the sefety nets of the generator by removing #4 screws M4.
Keep the body of the device and engine clean, by regularly using a soft mild cloth and a non-toxic and solvent-
free detergent. Do not rub too tightly and do not spill water on the components.
Do not use solvents.
In the presence of unusual noises and vibrations, check the tightness of screws and bolts.
Use only original spare parts by FRANCO s.r.l.

4.2 Replacement or cleaning of the nozzle
After making sure that the machine is stopped and cold, disconnect the electrical
and gas supplies. Remove with a hex wrench #7, the 4 screws holding the safety
net on the generator’s aspiration inlet.
With a 13mm hex wrench, unscrew the nozzle (fig.4.1), being careful not to drop
it into de burner or the machine (eventually, cover the hole temporarily).
Replace the old nozzle with a new one. Replace the safety net.
Verify the gas pressure before restarting the device.
