The circulation fan automatically switches on when the heater is activated.
Switching off:
 Set the rotary switch (Fig. 142,3) to " " (Fig. 142,4).
 Close the gas isolator tap "Heater/boiler" and the regulator tap on the gas
bottle.
After switching off the heater, the circulation fan may still run for a moment to
use up the residual heat.
Summer operation It is not possible to heat the vehicle in "Summer" operating mode. In "Summer"
operating mode, only the water in the boiler is heated.
Variant: Heater with gas
and 230 V electrical
operation
The heater can be operated with different types of energy:
z Gas operation (Fig. 143,3)
z 230 V electrical operation with the output levels 900 W (Fig. 143,2) or
1800 W (Fig. 143,1)
z Gas and 230 V electrical operation (mixed operation) with the output levels
900 W (Fig. 143,4) or 1800 W (Fig. 143,5)
The combination gas operation and 230 V electrical operation reduces the
heating-up time (only possible when the heater is set to winter operation at the
operating unit (Fig. 142)).
When 230 V electrical operation is selected, the yellow indicator lamp illumi-
nates (Fig. 143,6).
Z 230 V electrical operation is only possible when the vehicle is connected to
the 230 V power supply.
Z Select the output level for 230 V electrical operation so that it corresponds
to the fuse protection of the 230 V connection (900 W for 3.9 A fuse,
1800 W for 7.8 A fuse).
Z When the heater on the operating unit is set to summer operation and the
energy selector switch is set to mixed operation, the heater still runs only
in 230 V operation. The gas burner is not switched on.
