Installation
Place of installation
The heaters are intended for use in well ventilated areas only. Do not install the heaters in situations
that are not well ventilated. See also below for more ventilation information. Check also your local
regulations for the ventilation and room size requirements. The amount of heaters per building is
depending the type of building, the animals, the insulation, the climate and local wind conditions. Check
with your installer or distributor for a heat transmission calculation to determine the amount of heaters
needed.
Make sure that the place of installation is free of draft (less than 1 m/s). Too much draft will make the
flames unstable and will result in a lower infrared heat efficiency. It is advisable to install an alarm system
that reacts on temperature in case a temperature drop will cause damage. Find in the table below a
rough guideline for the installation height to start with. Adjust later on to the height based on your
personal preference and experience.
Operational Distances
To the ground
Safety distance to combustible materials
The heaters produce heat by radiation and by combustion gases. It is important to take the following
distances in account from the heaters to combustible materials. This is to avoid fire or overheating. Do
not use the heaters in situations where the distances to combustibles are smaller. Never store gases or
inflammable liquids or easy combustible materials in close vicinity of the heaters.
Safety Distances
to the ceiling
in front of the heater
to side walls
to the ground.
The minimum distance to non-combustible materials depends on the specific local situation. Keep in
mind that there must be sufficient free space left to vent the combustion gases away. Otherwise, they
will influence the combustion and proper function of the heater. On locations where the combustion
gases can vent away easily, a minimum of 25 cm to the ceiling is advisable. Note: Be aware that some
non-combustible materials can be subject to discolouring when they become too hot.
Warning: be careful with the use of heaters in places with storage of manure. Manure can contain large
amounts of methane and other inflammable gases.
Ventilation
A proper ventilation is extreme important for safe and convenient operation. Lack of ventilation can cause
production of carbon monoxide (very poisonous). Sufficient ventilation shall be guaranteed by a
monitored fan or by permanent, non-adjustable, ventilation openings. Consult EN13410 for more details.
Beside other important requirements this standard states in short that a 1,5 times room air replacement
per hour is sufficient in most situations. Also a maximum of 5W heat input per m3 room content is
considered to be safe. If this is not the case make sure that a minimum of 10m3/h air replacement per
1 kW heat input is guaranteed by means of fans or ventilation openings.
In case local requirements ask for more stringent ventilation, or when animals ask for more ventilation,
always follow the most stringent requirements. In case there are no requirements or standards for
ventilation in the country of installation, we advise to keep a minimum ventilation of 20m3/h per kW heat
input. Check regularly if fans are working properly and ventilation openings are not closed.
Installation
The heaters are intended for suspension only. The chain and S-hooks shall be galvanised or made of
stainless steel. Do not use the gas line, gas hose or electric lines for suspension purposes. Never use
rope or plastic mounting materials. Close all S-hooks when the heater is in correct position.
• Mount three short chains (of approx. 40 cm) with S-hooks to the three suspension eyes on the heater.
• Combine the ends of the three short chains together in the fourth S-hook and hang it on the main
chain. Mount the main chain to a rigid part of the construction of the building.
