Start-up
Ignition, closing doors
SH Operation
Under no circumstances should brushwood,
coarse wood chips or carpentry waste be used
for the bottom layer
. Such fine material burns
too quickly, resulting in incomplete combustion in
the combustion chamber, which is still cold during
start-up. As a result, soot builds up in the heat
exchanger.
Close fuel chamber door, open ignition door
Close the fuel chamber door and then open the
ignition door.
If the boiler is not to be started up yet, close both
doors and in the boiler overview,
press the on/off
button
so that it shines red
.
Ignite the fire with cardboard and newspaper
Place crumpled paper or a few pieces of cardboard
in front of the first layer of wood and ignite it.
The draught fan sucks the flame over the tightly
stacked logs, causing them to ignite more quickly.
For heavy, smooth hardwood, larger pieces of
kindling may be needed for ignition.
Never use petrol, turpentine or similar
materials as an "ignition aid"
: risk of
explosion!
The
ignition door should be kept open after
ignition to monitor the progress of the fire
. It
should only be closed once the boiler's exhaust gas
temperature has reached 100°C. How long it takes
the fire to start depends on the type of wood used;
rough spruce may need only 2 minutes, smooth
beech may require 5 minutes until the required
exhaust gas temperature of 100°C is reached.
