Operation
New heaters
New heaters need a cleaning period before they are ready for operation. Turn the ventilation to maximum
position or place the heaters outside in the open air. Fire the heaters for at least two hours on full capacity
to burn-off oily and greasy remnants of the production. Make sure that after two hours all smoke and
smell is disappeared. The smoke and smell can be unhealthy, so keep animals and human beings away
till the heaters and the environment air is clean.
Ignition of the heater
Warning: after an heater is extinguished (intentionally or unintentionally) wait always for 3 minutes before
(re)ignition. This is a worldwide safety rule and intended to ventilate unburned gases away and to leave
enough time for the thermocouple device to close.
TE, TEMK, TETH and TETHi versions:
1) Open all gas taps (and turn the thermostat or gas pressure regulator on maximum, open the MK valve
by electricity).
2) Keep a flame of a BBQ lighter (or long match) in the ignition hole of the burner globe.
3) Press the knob of the gas safety device and wait for 10-25 seconds after ignition before releasing the
knob.
4) The burner will stay on now.
5) Repeat al steps again in case the burner directly extinguishes.
Heat regulation of the heater TE
version:
The heat input of this heater can only be changed by adjusting the pressure of the gas supply. Check
the gas supply pressure information on the data plate of the heater for the minimum and maximum
values. If only one pressure is mentioned, adjustment is not possible and only continuous operation or
on-off operation is allowed.
TEMK version:
Make sure that the gas supply pressure remains constant at the value indicated on the data plate. Adjust
the heat input between high and low by opening or closing the MK solenoid valve.
TETH, TETHi versions:
Make sure that the gas supply pressure remains constant at the value indicated on the data plate. Adjust
the heat input by setting the thermostat knob at the desired value. Note that the temperature on the
ground will be several degrees higher than at the sensor. So use the setting on the thermostat knob as
a rough guideline and always check the real temperature on the ground
Extinguishing the heater
TE, TEMK, TETH and TETHi versions:
Close the gas tap or the central gas supply. The burner will extinguish now. The thermocouple safety
valve will close after 60 seconds.
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
