1-1-GENERAL RECOMMENDATIONS
These devices must only be installed in sufficiently ventilated buildings, except for devices equipped with airtight
connection.
The good operation of the air heater depends upon correct installation and start up.
Any non-respect of these rules would immediately imply the manufacturer’s discharge.
The installation and maintenance must be made according the regulation and good engineering practices in force, by skilled
personnel.
DO NOT INSTALL ANY GAS AIR HEATER IN:
- Premises with explosion risks,
- Premises with chlorinated combinations fumes,
- Premises with high combustible dust content,
- Highly humid premises (electrical danger),
- Domestic premises.
It is of the responsibility of the installer, after having checked that the assembly respects the prescriptions of these
instructions:
1°) To inform the user:
- that he cannot modify himself the devices design nor the installation implementation ; Any modification (exchange,
setting back….) of safety components or parts, that influence the device output or quality of combustion, systematically
implies the EC mark withdrawal.
- that it is indispensable to have the recommended cleaning and maintenance operations made. One yearly
preventive maintenance operation is compulsory.
2°) To give the user these instructions:
SOLARONICS Chauffage, with the EC marking notifying organization, reserves the right to update these instructions. Only the
instructions provided with the device can be considered as contractual. Do carefully keep them close to the device.
1-1 - Devices description - Operation
The Minigaz Evolution Eco suspended gas air heater is an independent warm air generator, operating with natural gas or propan e ;
it is conform to the European Directive 2009/142 that applies to gas devices.
It is a «direct» gas heating system ; it produces and emits heat without intermediary heat transfer fluid.
For the whole range described in these instructions, the combustion products exhaust ,outside the premises, is made by an
extractor. The combustion air is sucked in the inside or outside premises. These devices can be connected with vertical or ho rizontal
balanced-flue terminal or shaft outlet.
The Minigaz Evolution Eco suspended gas air heaters run with the various gas mentioned on their rating -plates according to the
European Directive
1.2. Use instructions
- For this device operation and maintenance, please read the instructions.
- Have at least one maintenance operation per year , by skilled personnel. The maintenance operations frequency depends
upon the environment where the appliance is installed. A regular inspection must be made specially in dusty premises.
- Check regularly that there is no distortion of the device, the chimney or the gas connections.
- Check regularly that the air openings of the premises and around the device are not clogged.
- Make sure that the warm air can normally circulate within the premises, and that there is no obstruction at suction (fan side)
nor in front of the supply air terminal device (open grid).
- The control box should be subjected to one electrical cut per 24 hours at least
1.3. Operation
- On heat request, the burner ignites thanks to the ignition electrode. The fan starts and the warm air is blown within the
premises. On reaching the set point temperature, the burner goes out. The fan goes on operating during about 1 minute, till t he
residual heat escapes from the heat exchanger

4/29
INSTRUCTIONS— GAS AIR HEATER - MINIGAZ Eco MH Eco, MC Eco, MV Eco– NT09004I-GB – 29/11/2017
1.4. Safety
- Any flame failure is detected by an ionization sensor and the gas by-pass valves immediately close.
- The exchanger thermal protection is made by two thermostats. The first one, with automatic resetting, protects from insuffici ent air output
(clogging, fan failure). The second one, with manual resetting, is set at upper threshold than the first one. It protects the device from major
overheating due to malfunction or inadequate using.
In case of trouble, please contact us.
Make sure that the device can be normally fed with combustion air at atmospheric pressure (any modification of the building f urther to the
installation must be made considering this point). Over-depression inside the premises can disturb the device operation by depriving it of
necessary air for combustion.
1.5. Switch-off
- To switch off the device for a short period, just cut off the thermostatic line (put the thermostat at minimum set point or c ut off the thermostat
switch).
- For extended stop, cut off the thermostatic line, close the gas valve and cut off the electrical power, carefully waiting for the fan stop .
Gas and electricity must be cut off only in case of emergency or for extended stop periods.

4-4 Remote faulty signal (in option)
The remote faulty signal kit (code 3510232) consists of replacing the 4-wire supply cable by a 5-wire cable.
The fifth wire (grey) is the failure report.
When the air blower is in failure it sends a 230V voltage signal that may be used to switch on a lamp or a relay.

Caution! The air blowers cannot be piloted by a standard thermostat (with relay). Only the specific “pilot wire”
thermostats supplied by Solaronics can pilot the air blowers.
The goal of the pilot wire is to limit the number of wires to connect.
The same pilot wire allows to transmit an order:
 Of ventilation
 Of heating
 Of reset

5– FLUE CONNECTIONS
Air combustion is taken directly in the building and by-products are released outside trough a vertical chimney
During the commissioning and maintenance, make sure that:
- Air combustion inlet and by-products outlets are not blocked.
- For coaxial flue assembly, check that the 2 circuits (air combustion inlet and by-products outlet) are
independent and airtight ; Check pipes assembly and seals..
- Not to damage the flue pipes seals when assembling the conduits onto the device, check the sealing
after assembly..
- The assembly of the flue pipes must be carried out so that no water can penetrate into the device
(danger electrical hazard). For this purpose, please use a purge T-piece and a condensate drain, …
- For greater lengths, it is essential to provide a condensate drain; this also applies to assemblies using
coaxial flue.
B22 - for MH Eco/MC Eco 16/21/28/35/50/60/80 type
Air combustion is taken inside the building and by-products are
released outside.
The K B22-80 (ø80), K B22-100 (ø100) and K B22-130 (ø130) kits
are made of a T piece (4), 2 one m pipes (3), a terminal part (1). The
K B22-80 kit is delivered with a sliding drip.
The flue shall be higher than the roof level (400mm minimum).
H dimension is equal to 2150 mm.
It is possible to shorten, lengthen or lead astray the flue thanks to
a wide range of flue accessories (0.5 or 1 m pipes, elbows,…)
* Remark: Flashing(2) is not included

Air combustion is taken inside the building and by-products are
released outside.
The K B2280V (ø 80) and K B22130V (ø 130) kits are made of
a 90° elbow (6), one pipe of 0,5 m (5), a T piece (4), two pipes of
1 m (3) and one terminal part (1). The flue shall be higher than the
roof level (400 mm minimum).
H dimension is equal to 2150 mm.
It is possible to shorten, lengthen or lead astray the flue thanks to
a wide range of flue accessories (0.5 or 1 m pipes, elbows,…)
* Remark: Flashing(2) is not included
Check that air renewal is sufficient: a minimum of 100 m3/h air flow per Minigaz is required
Flue pipes sections shall at less be equal to the starting section. Flue pipes shall be vertical or at the maximum with a
45 °angle.
Total length of flue shall not exceed 6 m ( taking into account than pressure drops in a 45° or 90° elbow are
similar to losses in a 1 m pipe).
If the length of the outside flue is more than 2 meters an insulation shall be installed

C12 - for MH Eco 16/21/28/35 an MC Eco 21/28/35 type
Combustion air is taken outside and by-products are released
outside. The connection is done horizontally.
The K C12-80125 (ø 80/125) kit is made of a concentric flue (1)
and of two rubber flanges (2) which enable a perfect finish.
The coaxial flue of 80/125 diam. is directly connected to the air
blower.
The (A) dimension shall be between 200 and 350 mm. When
coaxial flue is connected to the air blower the dimension (B) is
750 mm.
It is possible to shorten, lengthen or lead astray the flue
thanks to a wide range of flue accessories (3) (pipes, elbows,
…)

NON
Correct assembly Incorrect assembly
α = 2°
Assembly of the flue pipes must be carried out using a slope opposed to the device, α = 2° minimum .
Connection of pipes has to be done horizontally.
Junctions shall be airtight and rigid.
Flue pipes sections shall at less be equal to the starting section. Flue pipes shall be vertical or at the maximum with a
45 °angle.
Total length of flue shall not exceed 6 m ( taking into account than pressure drops in a 45° or 90° elbow are
similar to losses in a 1 m pipe).
If the length of the outside flue is more than 2 meters an insulation shall be installed.
CAUTION
The use of airtight pipes implies a perfect air tightness of the junctions. Thus in order to make the assembly easy it is
necessary to use a non corrosive lubricant (for example: soap water).
