WARNING: Care should be taken to
ensure adequate ventilation of the flue at all
times. It is inadvisable to inhale exhaust fumes.
For operating on gas turn on gas cylinder and
open the shut off valve at the manifold.
For operating on electric operate the heater
/ heating system heater switch on the power
supply unit. See page 69.
Summer operation (boiler operation only)
Mixed operation (gas and electrical) is not
possible in summer mode. With this setting the
unit automatically selects electrical operation
with a preselected power setting of 900 W or
1800 W.
Winter operation
• Heating with water temperature
monitoring
The device automatically selects the
required power setting in accordance with
the temperature difference between the
temperature selected on the control panel
and the current room temperature. When the
room temperature selected on the control
panel is reached, the heater switches back
to the smallest setting and heats the water
to 60 °C. Once the water temperature is
reached, the heater switches off and the
yellow LED (p) goes out. The warm air fan
can continue to run in order to cool the unit
(after-run).
• Heating without water temperature
monitoring
The device automatically selects the
required power setting in accordance with
the temperature difference between the
temperature selected on the control panel
and the current room temperature. Once the
room temperature selected on the control
panel has been reached, the heater switches
off. The warm air fan continues to run at slow
speed until the outgoing air temperature (on
the unit) has fallen to 40°C or less.
If the boiler is filled, the water will
automatically be heated at the same time.
The water temperature is then dependent
on the heating output being given off, and
the duration of heating required to reach the
desired room temperature.
• Heating with drained water system
Depending on the operating mode, the unit
will automatically select the required power
level according to the temperature difference
between the setting on the control panel
and the current room temperature. Once the
room temperature selected on the control
panel has been reached, the heater switches
off. The warm air fan continues to run at slow
speed until the outgoing air temperature (on
the unit) has fallen to 40°C or less.
Filling the water heater
Switch on power for water pump (main or
pump switch).
Open hot water taps in kitchen and bathroom,
(set preselecting mixing taps or single-lever
fittings to "hot"). Leave the fittings open for as
long as it takes for the boiler to displace the
air and fill up, and the water to flow without
interruption.
If just the cold water system is being operated,
without using the water heater, the heater tank
also fills up with water. To avoid frost damage,
the boiler must be drained through the drain
valve, even if the boiler was not operated.
When connecting to a central water supply
(rural or city mains), a pressure reduction valve
must always be installed to prevent pressures
above 2.8 bar from developing in the water
heater.
Draining the water heater
Switch off power to water pump (main or
pump switch).
Open hot water taps in kitchen and bathroom.
In order to check the water that is flowing out,
place an appropriate container (capacity 10
litres) beneath the drain valve.
Open the drain valve which is situated next to
the boiler by lifting the yellow handle into the
vertical position.
Check whether all of the water in the boiler (10
itres) has been drained into the container via
the drain valve.
There shall be no claims under guarantee
for damage caused by frost!
