Visual examination of the flame
Check after every ignition (and also during regular barn inspection) if a heater still burns correctly. The
flame shall remain always inside the outer burner globe. The burner globe shall be equal red/orange in
high firing position and having a blue flame. Some types will have in high fire position a dark ring on the
globe. This will not give a problem and is created by cooling air around the flame. A little bit yellow tipping
or yellow glow in low fire is allowed.
A burner does not operate well in case there is a (green)-blue cloud inside the reflector and/or (green)
blue flame tongues are coming out the exhaust holes in the reflector. Soot deposit on the reflector and
yellow flames are also a sign of bad functioning and are not allowed. Cleaning will solve these problems
in most cases. When gas is used with a lot of butane instead of propane the centre of the outer globe
will become overheated. The centre will be white-yellow hot coloured; small flames of a few mm will
come through the perforation of the globe. The globe will burn through after some time. Take action
when this is noted.
In high fire operation, the flame makes a soft roaring noise. In case the burner makes a loud roaring
noise and the burner globe does not become equal red/orange, the inner burner globe is damaged and
the flame is burning inside the venturi tube (back firing). The venturi tube becomes very hot now behind
the venturi. Directly extinguish the heater and replace the damaged unit by a new one.
Emergency operation (Only models: Ei, 2FEi)
The Global heater has the option to be converted to
full manual operation without the need of electricity
anymore. This can be an emergency solution in case
a long-term power breakage occurs in the barn or the
electronic sparking unit breaks without having a spare
one on stock. The conversion to manual operation
takes 2 minutes per brooder. See figure at the right
side (situation shown after conversion). The numbers
between brackets refer to this drawing.
[1] Unscrew the thermocouple nut (1) from the black
electronic ignition device.
[2] Unscrew the nut of the extension wire (3) from the
gas safety valve, leaving this one unconnected.
[3] Screw the thermocouple nut (1) on the gas safety valve. (replacing the nut of the extension wire).
Now the EID2G is completely overruled, electric power is not needed anymore.
[4] Push the knob (2) of the gas safety valve and light the burner with a hand ignitor (long tip BBQ lighter)
at the location of the 8-mm hole in the burner globe.
[5] After ignition of the burner keep the knob (2) pushed for 20 seconds. The thermocouple of the gas
safety valve will take over the operation and the burner will stay alight.
[6] To extinguish the burner, close the manual valve in the gas supply line before the brooder. After 60
seconds cooling down the safety valve will close also.
Game rearing
Global heaters are used a lot for game rearing. Especially for game rearing, due to the small cages and
active birds, pay a lot of attention to cleaning and ventilation. While the cages are small, the effect of
lack of ventilation and not cleaning will be directly causing the death of birds in a short time. While
normally one heater is used for one cage, we advise to add an independent temperature alarm system
for those situations where a temperature drop due to a (gas supply) failure will result in bird loss.

Service and maintenance

General
The frequency of maintenance is strongly depending on the quality of the combustion air and the
intensity of use. When used in poultry houses, maintenance is advised every 6 weeks or by changing
the animals. By use in clean environment conditions, the maintenance period can be extended but not
longer than 6 months. In case heaters are not used for a long period, always do maintenance first before
using them again. Wear safety goggles during cleaning with compressed air.
Parts that are broken, or are not functioning well, must be replaced directly by identical ones of same
brand and type. Consult the dealer or manufacturer in case of doubt.
