Checking the low-fire rate setting
CAUTION
To avoid damage to the heater TR, please observe
the following:
– The low-fire rate may only be set by author-
ized trained personnel by agreement with the
manufacturer.
▷
The heater must be operated at minimum capac-
ity, see page 10 (Display and selection of the
capacity setting).
▷
The combination control regulates the gas supply
according to the reduced air supply.

Contact the manufacturer if the measured CO
2
value differs from the high-fire rate by 0.5%.
Further adjustments may only be made by
agreement with the manufacturer. Otherwise,
the warranty will be voided.
▷
The CO
2
value is adjusted by changing the zero
point on the combination control at N.

Flame signal
▷
The flame signal can be displayed when the
burner is operating.
Pressing the RESET button displays the flame
signal.
▷
It appears in coded form as a number from 0 to 9.
For a gas appliance the number must be
multiplied by a factor of 2. The result of
this multiplication is the flame current in µA.
Example: the number 3 corresponds to a flame
current of 6 – 8 µA.

Cleaning
CAUTION
To ensure that no damage occurs during operation
and cleaning, please observe the following instruc-
tions. Otherwise, injuries or damage to the device
may occur and/or the function of the device may
be impaired, and the manufacturer’s warranty will
be cancelled.
– Sharp-edged metal sheets. Always wear protec-
tive gloves.
– After cleaning, check that the components on
and in the heater are in good condition. The
device may only be restarted if all safety devices
have been installed and the safety functions
have been checked.
– Clean the heater once a year when used in
horticulture and at regular intervals as well as
after each fattening period when used in agricul-
ture, as described below. Inadequate or irregular
cleaning can cause the device to overheat and
can thus lead to fire damage or damage to the
device. For example, dirt particles can catch
fire and can be blown out of the device.
▷
The TR is made of high-quality stainless steel
and is resistant to external influences such as
dirt and moisture.
▷
It is designed so that it can be cleaned carefully
both inside and outside with a high-pressure
cleaner.
▷
The housing cover and cable glands on the
burner control unit must be closed during the
cleaning process.
▷
The electrical components are protected from
moisture by additional water drip edges on the
housing cover. Nevertheless, direct water influ-
ence on the edges of the housing cover should
be avoided.
▷
A downward slope inside the device ensures
that dirty water drains out.
▷
Never direct the high-pressure cleaner at the
heater when it is set to water jet. Always use
the spray setting.
▷
The distance between the nozzle and the surface
to be cleaned must always be at least 50 cm. Too
short a water jet from the high-pressure cleaner
can cause serious damage to the device.
Switch off the burner control unit.
Disconnect the system from the electrical power
supply.
