1-1 General recommendations
RTGI-RTG Direct gas heaters are designed for horticultural premises, livestock or for supplementary
heating in industrial premises.
The unit can only be installed in rooms which are sufficiently ventilated. If you intend to use the heater in
a room with a dusty or dirty atmosphere, like poultry houses, the combustion air inlet must be well-sealed
and connected to the outside.
Do not block the supply grille and ensure that the hot air circulates freely. Do not put anything within 5
meters from the supply grille of the unit.
This unit is designed for direct blowing, do not connect supply duct to the unit.
The proper functioning of the gas heater depends on correct installation and commissioning.
The installation and maintenance must be carried out by qualified personnel in conformity with the
regulatory texts and the rules in force.
The non-compliance with such rules entails the rejection of all responsibility from the manufacturer.
DO NOT INSTALL GAS HEATERS IN :
- Rooms which have a risk of explosion,
- Rooms containing chlorinated combination steam,
- Rooms with a high content of combustible dust,
- Rooms which are excessively humid (electrical danger).
- Domestic premises
After having checked that the installation, respects the recommendations of this notice, it is the
responsibility of the installer:
1) to inform the user:
- that he cannot carry out itself any modifications to the design of the devices or the method of carrying
out the installation; the least modification (exchange, withdrawal....) of safety components or parts which
influence the efficiency of the device or the hygiene of combustion will systematically cause the
withdrawal of the EC marking.
- that it is necessary to recommend cleaning and maintenance operations.
An annual preventive maintenance operation is compulsory.
2) to give these instructions to the user. They form an integral part of the device and must be retained
and must accompany the device, even in the case of sale to another owner or user.
Being always intent on improving the quality of our products, we seek to improve them on a permanent
basis. We therefore reserve the right, at any moment, to modify the specifications shown in this

1-2 Unit description
The direct gas heater RTGI-RTG is a direct combustion heater, running on natural or propane gas ; it is
in conformity with the European directives 2009/142/CE and 2009/42/CEE applicable to gas devices
(EN525:2009, certificate No. 1312CQ6091 from 06/10/2015).
It is a direct gas heating system. For all the range describe in this manual, the release of combustion
products is made by a fan placed upstream of the combustion chamber. The combustion air can be
taken from the room or the outside.
The direct gas heater RTGI-RTG is running with different gas indicated on the label and in accordance
with the European directive.
1-3 Operation

6
RTGI-RTG heaters are designed to heat horticultural premises, livestock or to be used for supplementary
heating in industrial premises.
They are composed of a premix burner, set into the flow of air, and a fan to diffuse the hot air.
The combustion air, sucked by a variable combustion fan, go through a Venturi system which controls the
good quantity of gas according to the airflow. This mixing is moved to the burner. The ignition probe fires
the air/gas mixing and the ionization probe checks if there is a flame.
The flame located in the air stream raises the temperature of the air supplied into the room. The gas and
combustion residues are diluted in very low quantity in the heating air.
For versions with modulating burner or variable air fan, it is also possible to vary the power and/or the
airflow.
1.4 Specific safety measures
The flame of RTGI-RTG direct gas heaters is in the « open air », it is very important to respect a minimum
space between the heater and the persons, the animals or the cultures (see Section No. 3
INSTALLATION). Failure to comply this obligation can be very dangerous, even if the unit is off because
the ignition is automatic.
The combustion of gas produces CO2, amongst others. A CO2 content in the air can be a danger for
people, animals and cultures. Therefore, you need to ensure that the fresh air supply is adapted to the
room where units are installed. When the CO2 concentration is too high, the heater does not work
correctly because of an incomplete combustion (danger with carbon monoxide CO). The CO2
concentration shall not exceed 1%, and the minimum ventilation requirements for the room where units
are installed is 1000 m3/h for each 100 kW of installed power.
For use in greenhouses :
Additional measure to respect :
- The CO2 level shall not exceed 1% (10.000 ppm).
- If the greenhouse is totally closed, you must foreseen ventilation system to have 100m3 of fresh air by
m3 of burnt gas and a minimum ventilation of 1 000m3/h for each 100 kW of installed power.
- In the absence of mechanical ventilation, it requires at least two opposite opening, to ensure enough air
circulation.
- It is recommended to use the heater with one or several extraction fans and a CO2 detector.
- Do not use sulphurous fuels into the space where the heater is used, because they contain high quantity
of sulphur that could be dangerous.
For use in poultry houses :
During the cleaning and/or the disinfection of a poultry houses or the spreading of the litter, the following
precautions should be taken. The non compliance can cause an explosion or a fire.
- The CO2 content shall not exceed 0,3% (3000 ppm).
- In the absence of mechanical ventilation, it requires at least two opposite opening, to ensure enough air
circulation.
- Protect or remove the heater during the cleaning/disinfection of the building.
- During the spreading of the litter, the heater must be covered in order to prevent the particles from
getting inside the unit and risking a fire. Disconnect the heater and cut off the gas to avoid unintentional
start.
- Clean the unit after each batch of poultries to remove any residues and to avoid soiling.
- Do not use water when you are cleaning the heater.

The installation and maintenance must be carried out only by qualified personnel.
3-1 General rules
The direct gas heater can be installed directly into the heating room.
Nevertheless, the installer must comply with laws and rules applicable in the destination country. If there
is any doubt, request information from inspection and security bodies.
Ventilation :
In rooms where direct gas heater is installed, must have continuous ventilation of minimum 100 m3 of
fresh air per m3 of burnt gas or must be connected with airtight pipe from the outside. When the heater
is working, the ventilation of the room must be at least 1000 m3/h for each 100 kW of power installed.
Gas connection :
Before installing the heater, it is necessary to check that the local supply conditions (type of gas, pres-
sure) are compatible with the device setting.
CAUTION :
Respect the minimum installation spaces below for safety and maintenance :

CAUTION
- The junctions must be sealed and the section of air pipe must be at least equal to the inlet diameter.
- The total length of the connection cannot exceed 6 m, knowing that : elbow 90° or 45° = 1 m of pipe.
- Pipes and accessories must be approved, use only the ones referenced by ALETRA. The use
of material non approved makes the manufacturer warranty void.
3-3 Air inlet connection
During the commissioning or maintenance, make sure that :
- Blowing grilles and combustion air inlet is not obstructed.
- Pipes are well sealed and installed to ensure that no water can come inside the unit and so to
avoid electrical hazard. For this, you can use: drain Tee cap, condensate recuperator, etc.
The unit is delivered with burner air inlet (A1). Depending on the type of local, it is necessary to mount :
- Either the protection air inlet grille on the front plate of the burner compartment (A2). In that case,
ensure that there is enough ventilation into the room, the required fresh air supply for combustion
must be at least 100m3/h per m3 of burnt gas.
- Either the sealed air inlet connector on the front plate of the burner compartment (A3). This
mounting is required if the heater is used in dusty, dirty o aggressive atmosphere (poultry
houses for example).
The use of airtight pipes involves a perfect sealing of junctions. Then, to facilitate the mounting, it is
necessary to use lubricant, non-aggressive for seals (Example: Soapy water)
The connection of the combustion air inlet must be horizontally through the outside. The mounting must
be realized with a slope opposite to the unit with an angle of 2° minimum, to prevent water into the
unit.

6. MAINTENANCE
We recommend a proper and regular maintenance, at least once per year. The heaters used in dirty or
dusty atmosphere (poultry houses) must be maintained more frequently. These interventions must be
carrying out by qualified professional.
6.1 Maintenance
The maintenance must be carrying out when the unit is cold and the gas and electricity are cut off.
Do not use water to clean the unit.
Perform the following operations :
- Clean the body, inside and outside the unit, the fan (blades, motor, protection grille)… Clean carefully all
components.
- Check if the cables, nuts and bolts are properly tight.
- Check the mounting and tightness of gas connections.
- Electrodes : Ignition flame and control cables must be inspected. In case of damages, replace it. Check
electrode gap., see section « Burner cleaning ».
Specific maintenance for poultry houses
In addition to operations above, clean and check the heater each time a change is made to a new batch,
before spreading the litter.
1. Take off the possible faeces or dust on the motor fan. The layer deposit acts as insulator, which can
cause a motor overheat.
2. Use a soft brush, no flexible metal, to take off all the dried deposits.
3. Blow the clean parts, in particularly inside and outside the body of the unit, the blades of the fan, the
motor of the fan, the thermostat, the switch,…
4. Clean the burner with a soft brush, no flexible metal, be careful to do not use compressed air, the
projected durst risk to stuck into the perforations of the burner grille and block them !
5. After cleaning, switch the unit on forced heating and let it warms enough to burn the possible dust
particles due to cleaning.
6. Stop heating, once the unit is completely cold, cover it to prevent possible combustible particles to
settle during the room cleaning.
7. Be sure that the heater is electrically isolated. The switch disconnector is turned off !
8. Disinfect the poultry house and spread the litter.
9. Take off the cover of the heater.
After cleaning the heater, you must perform the following controls :
- Open the gas and check the connection is gas-tight. If the heater has been moved, check that the gas is
correctly connected. Be careful, an improper sealing might cause a fire.
- Check the cabling.
- Check the sealing of the burner air inlet, fig.1
- Control and/or check all the recommended operations during commissioning, particularly :
- Gas pressure control
- Combustion control
- General functioning control
When finished the inspection, close the technical compartment carefully sealed and refit the grill to close
the combustion chamber fig. 2.
