1 GENERAL RULES
This instruction manual is an integral and essential part of the appliance and must be kept carefully
beside the appliance for further consultation.
Read the instructions and warnings contained in this manual carefully as they provide important
information on safety, installation, use and maintenance.
IMPORTANT !!
In the event of this manual being misplaced contact the manufacturer immediately.
Several appliances installed in the same room or in directly communicating rooms, are considered as
a single system, with a thermal capacity of the total of the thermal capacities of each single appliance.
Their use is not permitted to heat rooms destined for handicraft or industrial activities in which processes
and materials stored may cause the formation of gas, vapours or powders susceptible to induce fires
or explosions.
Installation must be performed by professionally qualified personnel responsible for compliance with
the current safety standards. The manufacturer declines all responsibility in the event of damages
caused by erroneous installation or improper and/or incorrect use of the appliance.
The packaging materials (nylon, foamed polystyrene, wood, staples, etc.) must not be left within the
reach of children as they are potential sources of danger.
Initial ignition of the appliance must be performed by qualified personnel.
In the case of the appliance shutting down or functioning incorrectly it must be switched off. Any
repairs or replacement of spare parts must be performed solely by qualified personnel using exclusively
original spare parts. Non-compliance with the aforesaid rules may endanger the safety of the appliance.
To guarantee correct operation of the appliance it is fundamental to carefully follow the instructions
provided by the manufacturer and to have the appliance serviced by qualified personnel at least once
a year.
N.B. To switch off the appliance always used the ambient thermostat and not the master switch on the
control board on the ground, as this could cause overheating in the combustion chamber with
consequent damage to the appliance.
The heater may be installed outdoors with temperatures down to -15°C. Below this temperature operation
of the appliance is no longer guaranteed.
2 PACKAGING
2.1 List of packing
a) The appliance complete with all its parts is delivered packed and wrapped in a protective nylon film
inside which the following are also found: the wall-mounting brackets, the electric control board
with relevant thermostat with probe (if requested) and two air/fume terminations (if requested).

3 GENERAL TECHNICAL SPECIFICATIONS
3.1 Description and operating specifications
EOLO suspended gas warm air heater is composed of a combustion chamber in stainless steel,
inside which a gaseous component (natural gas or LPG) is combusted. In just a few minutes the
external surfaces of the combustion chamber and fume tube nest, lapped by ambient air circulated by
the fans, reach their operating temperature.
The appliance operates automatically; the systems for electronic control, mixing, combustion, ignition,
suction of combustion air and discharge of fumes are housed in a compartment provided with an
inspection hatch that makes adjustment and maintenance operations easy to perform. A fan-limit
safety bi-thermostat controls start-up and shut-down of the fan unit, also shutting down the burner in
the case in which the supply air temperature exceeds the safety values permitted.
Suction of combustion air and discharge of fumes can be conveyed directly outside the building (type
C appliance); therefore, there is no communication between the combustion chamber and the indoor
environment (this guarantees maximum safety).
In the summer the fan unit can be operated alone to provide ambient comfort and provide a supply of
fresh air. To switch to this operation press the button on the aluminium front of the bi-thermostat.

3.3 Main control and safety components on the appliance
a) Electronic control unit: one for all models. This controls opening of the gas solenoid valve and
ignition of the burner. After receiving the electrical signal from the ambient thermostat, it checks
that the pressure switch is operating normally (ignition is not enabled unless this check is passed).
It then enables prewash of the combustion chamber (4 exchanges) and then ignition by means of
a spark. If the flame is not detected (ionization probe) within the safety time the appliance shuts
down. To restart it wait a few seconds and press the specific reset button with LED on the control
board.

Safety time at shut-down .............................. < 1sec............................. < 1 sec
b) Differential pressure switch: the aim of this is to interrupt operation of the appliance if the flow rate
of the fan-exhaust fan is insufficient caused either by a fault in the fan or by clogging in the combustion
circuit (combustion air duct, combustion chamber, heat exchanger, combustion products discharge),
both of which can be caused by bad combustion CO forming above the permitted limits. This is
located inside the compartment which houses all the control components, and detects, by means
of two silicone tubes, both the pressure in the combustion air suction duct and the pressure inside
the burner box in which the combustion torch is located. The difference between the two pressure
values with the exhaust fan operating is the control signal for safe and correct combustion.

aluminium body are the threaded gas inlet-outlet connection ½ RP UNI-ISO 7, with relevant pressure
inlet and outlet. Gas valve adjustment and the only maintenance operation that can be performed
on the valve (replacement of the coils) must only be executed by qualified technicians.

d) Fan-limit safety bi-thermostat with automatic reset: this has a double aim:
-to control start-up of the fans after the air has reached 50°C and shut-down of these when the air
temperature has dropped below 30°C;
-to interrupt operation of the appliance if there is abnormal overheating of the air (>90°C); the appliance
can be reset manually using the reset button located on the board.
