Safety Mechanism
Should overheating occur, the safety temperature lim-
iter (STB) interrupts the gas supply and locks the unit’s
electrical system. All unit functions are switched off.
“RESETTING” is not possible before the sensor has
cooled down to below approx. 90 °C.
The unit is released once the protective cap has been
unscrewed by pressing the “STB-RESET“ button.
1. Remove the protective cap 1
2. Press the reset button 2.
3. Replace the protective cap.

Before resetting the unit, check the operating con-
ditions to ensure that the STB temperature is not
exceeded again.
1. Release the burner by
pressing the reset button.
2. Please note that the burner
can only be reset after wait-
ing 60 seconds.
Burner
If the flame burns unevenly or goes out, the unit is
switched off by the burner. The malfunction light of the
burner lights up.
Maintenance
Depending on the operating conditions, the units must
be serviced as necessary, at least once every two years
by a authorised individual to ensure that they are func-
tioning properly
The test results must be recorded in a test log which is
kept in a safe place until the next test so that it can be
provided to authorised persons for control purposes at
any time..
The people responsible for operating the unit must in-
spect the unit prior to beginning work for visible defects
of the operating and safety mechanisms as well as to
ensure that the protective mechanisms are there and
working properly. If defects are found, the supervisor
must be notified.
If defects are found that jeopardize the operational
safety of the unit, the operation of the affected compo-
nents must be suspended immediately!
Regular maintenance and care, especially after each
heating period, are required to ensure a long service life
and a faultless operation of the unit.
1. Shut off the gas supply and unplug the unit from the
power supply.
2. Remove the blow-out grille, the outside casing and
the inspection cover.
Important instructions for the cool down phase for
units whose fans continue to run automatically (PGT
100 / 100 E).
The fans keep running automatically to prevent heat
from building up inside the unit which, in turn, keeps the
STB from being triggered after the burner is switched
off.
For this reason, the electrical connection may not be
separated from the power supply before the fans have
stopped running except in emergency situations.
When the unit is being serviced, adjusted or re-
paired, the gas supply has to be turned off and the
unit unplugged from the power supply!
Unit Shut Down
1. Close all cylinder valves.
2. Let the flame burn out.
3. Set the operating switch to “0”.
Off.
4. Unplug the unit plug from the power
supply.
Please observe the following:
The unit must be maintained and cleaned at regular
intervals.
The unit must be kept free of dust and other deposits
and may only the cleaned using a dry or damp cloth.
Do not use place the unit in a direct stream of water.
Do not use any aggressive cleaning agents or those
which are harmful to the environment.
Do not use cleaning agents which contain solvents.
Use only suitable cleaners even when the unit is ex-
tremely dirty.
Check air suction and blow-out grille on a regular
basis and clean when necessary.
Make sure that the air intake for combustion air, the
injector behind it and the gas nozzle are not dirty.
Check gas burner, gas nozzle and gasket for dam-
age; replace when necessary.
Clean baffle plate regularly.
Bright yellow flames are an indication that the
fresh air supply is insufficient or that there is dirt
inside the unit.
