The gas hose shall be hanging free and have a distance of minimal 1 meter from the ground (AP-1, AP-
3 as much as possible). This to make sure that animals will not damage the hose. Connect the hose via
an individual gas tap to the central gas supply.
A guideline for placement of the sensor of the temperature regulation is 60 cm above the ground and
minimal 40 cm away from a heater. Use sensors with a black surface in case the regulation is based on
measuring the infra-red temperature.
Gas line supply
In case a main gas line supplies the gas to the heaters, make sure that an authorised company in your
country, in accordance with the local rules and requirements, install the system. To avoid problems, use
galvanised or copper tubing for the gas line. First make a calculation to determine the capacity of the
whole system and the diameters of the piping in each section. Use the common available calculation
methods as written in most gas installation standards. Contact an installer or the distributor in case this
calculation method is not available in your area. For data needed to calculate the dimensions of the gas
line, see the technical table on the last page.
The most common way to install a gas line is
in the centre of the barn (at least 2 meter
high) with every 3 to 5 meter a "T" or "cross"
connection for gas supply to the heaters.
Always mount a (easy reachable) gas tap at
the beginning of the gas hose to the heaters.
This gas tap is needed to close the gas
supply to the burners to extinguish the
flames. In addition, it makes it possible to
remove the heaters after use or to service the
heaters safely. The gas inlet at the heater
side is standard a 8 mm hose nipple (optional a smooth hose nipple or a G1/8" right handed thread.
Other connections are possible after consultation). Always use approved gas sealant to close the gas
connections.
Gas cylinder supply
The gas can also be supplied from LPG gas cylinders. The minimum size is a 11 kg cylinder or larger.
Before buying a cylinder make sure that the connections of the gas regulator and the gas valve of the
cylinder are of the same type. Check with your gas supplier for the correct size of gas regulator. Check
the technical table for the maximum gas consumption and gas pressure.
Store the gas cylinders always on ground level in a well-ventilated place, preferably outside the room
where the heater is. In case the gas cylinder is placed in a cylinder housing, or cover, make sure that
there is enough ventilation as requested by the applicable regulations or standards. Never obstruct these
ventilation holes. Make sure that the gas cylinders are used in upright position only and are secured
again tipping over during use. Gas cylinders laying on their side will give liquid gas. This is very
dangerous and will give a fire ball when it reaches the heaters.
In case the gas cylinder is placed in the same room as the heater is, keep it at a safe distance from the
heater so it will not be over heated. Advisable is at least 2 meters. Make sure that the gas cylinder valve
can easily be reached to close the gas supply in an emergency. Pay special attention how to change
the gas cylinders in a safe way.
