Note
Ensure that the safety latch engages and that the
hopper cover is securely closed.

Open the ash chamber door.
0 7. Danger
Risk of severe injuries due to highly-flam-
mable materials when igniting the fuel.
Never use highly-flammable substances
such as petrol, oil, alcohol or solvents to
ignite the fuel.
Ignite the paper across the entire width of the hop-
per.
Note
This allows the flames to spread quickly across
the entire grate area. A quick heat up means per-
fect combustion is quickly achieved.
0 8. Switch the boiler on at the control unit. Press the
"
START/STOP " button.
0 9. Now swivel the ash chamber door down and leave
it open about 10 cm.
10. Supervise the heating system during the heat-up
phase until a flue gas temperature of 110 °C is dis-
played.
Note
To display the flue gas temperature, call up the
"Boiler" menu item in the standard menu.
11. Close the ash chamber door as soon as the flue
gas temperature has reached 110 °C.
Note
Ensure that all covers and doors are tightly shut
during operation. This safeguards optimum com-
bustion.
Recharging fuel
Note
When charging with pieces of residual wood, wood bri-
quettes and residual wood with shavings, logs should
be regularly added. This ensures better combustion.
A full hopper charge will provide a combustion period
of 3 - 4 hours, depending on the amount of heat being
drawn off and the quality of the fuel.
Flue gas temperature > 120 °C < 120 °C to > 60 °C < 60 °C
Steps to take Do not recharge with fuel. Recharge with fuel. Repeat the heat up proc-
ess. See page 16.
Danger
Flue gas escaping via the hopper cover poses a
risk to health and the environment.
Wait until the temperature of the flue gas has
dropped below 120 °C before opening the hop-
per cover briefly to recharge with fuel.
