Note that the heaters will be a bit discoloured by temperature due to a 5 minutes quality check after
manufacturing.
The thermostat knob is always delivered separated from the thermostat valve.
1) Remove the protection cover from the thermostat valve.
2) Turn the knob on maximum temperature and push the knob on the valve.
3) Fix the knob by turning the large metal screw ring till it stops (at least 2 turns, hand tight).
For thermostats with a remote sensor only: bend the sensor line carefully (no sharp bends) to the
thermostat valve and secure the sensor line with a ty-rap around the red protection lining and the
thermocouple safety device (see picture). Note that the tubing is hollow, a sharp bend will close the
tubing and makes the sensor worthless. The chance of breaking the line at the entrance of the
thermostat knob is largely limited now.
Installation
Before installation, check that the local distribution conditions, nature of gas and pressure, and
adjustment of the appliance are compatible. Make sure that the gas is clean. Install a gas filter and
condensate trap before the heaters in case the gas is dirty or wet/oily. No guarantee can be given on
heaters operating on gas that is not clean.

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 below for more ventilation information. Check also your local regulations
for the ventilation and room size requirements. The number 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 number 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 infra-red 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 afterwards to the height based on
local temperature measurements and your personal preference and experience.

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.
