Setting /Regulation of Heating Capacity
Set desired heating capacity at the continuous "Power
Regulation".
The setting can also be continuously changed during the
unit operation.
Ventilation
Put the operating switch into position.
In this position only the supply air fan
runs and the unit can be used for air
circulation.
Heating is not possible!
Important Hint!
Make sure that the supply air can be freely sucked and the
heated air can be blown of without problems.
Make sure to keep the safety distance from combustible
and inflammable materials and to observe the local fire
protection codes.
4. STOP Shut-down
Close all the cylinder valves and stop
valves ot the supply line.
Let the flame burn out.
Put the operating switch into "0" position
(= Off) and unplug the mains plug from
mains socket.
Install only in well aerated rooms, but not in
!
living areas and recreation rooms!
Turn to the left:
larger heating capacity
Turn to the right:
smaller heating capacity
Unit Function
When the unit has been switched on (operating switch i
position "I" = heating operation), the supply air fan is started
and the electric solenoid opens. However, gas supply to the
burner is still blocked. Gas supply to the burner is released
only after having pressed on the pin of the thermoelectric
gas valve (safety pilot).
The liquid gas is supplied by means of a nozzle under
pressure to the burner pipe, where it is enriched with an
adequate quantity of oxygen which has been adapted to the
burner capacity concerned.
The generated gas-air-mixture is ignited at the burner head
by an electric ingition spark. The spark is generated by the
manual actuation of the piezo igniter. The thermoelectric
control of the flame is started by heating the thermocouple.
The pin of the safety pilot is to be released.
Gas supply is interrupted in case of operating troubles or
when the flame goes out. However, the supply air fan
continues working. The unit has to be restarted.
In the case of overheating, the gas supply is interrupted by a
safety thermostat (STB) which blocks all the functions of
the unit. A manual release of the STB can be carried out only
after the unit has cooled down.
During the operation of the unit the min./max. heating
capacity can be regulated continuously by means of the built-
in "Power Regulation".
Interference Elimination
The unit is equipped with a safety thermostat (STB) which,
in the case of overheating, interrupts gas supply and locks
the electric devices of the unit. Any functions or the unit are
switched off.
If the safety thermostat has been released, the reason for
the trouble is to be localized and to be eliminated. Release
is to be carried out after having screwed off the protecting
cap and after having pressed down the key "STB-Reset".
The "RESET" position can only be set when the feeler has
cooled to a temperature below approx. 90°C.
In the chapter "Troubleshooting Instructions" you will find
a detailed chart regarding the elimination of faults.
