9. Connecting to the chimney
HAAS+SOHN oil stoves can be connected to any
normal-draught chimney, either directly (see Figure 14)
or with a so-
called “Starting section” (see Figure 15).
However we do not advise connection to an external
wall chimney. A commercially available steel sheet flue
pipe should be used for connection to the chimney.
HAAS+SOHN oil stoves already operate perfectly on
low setting even at a delivery pressure (draught) from 8
Pa. If the draught is lower it cannot be guaranteed that
your oil stove will burn without problems. Before
verifying the delivery pressure the stove should have
been in operation for at least half an hour. Your master
chimney-sweeper will know how to measure the
delivery pressure.
Delivery pressures above 20 Pa are compensated by
the primary air limiter (PAL) installed in the appliance
or, on some models, by the integrated draught limiter
(see Chapters 12.3. and 12.4.). With extremely high
draught intensities (above 60 Pa) we recommend
installing a lockable damper flap in the flue gas pipe,
but it is imperative to discuss this with the master
chimney-sweeper. Flue gas damper flaps or other
choke installations are not otherwise permissible in the
oil stove.
The flue pipe must be firmly and tightly connected both
with the flue gas spigot and with the chimney. This
secure and tight connection is also absolutely essential
between the individual flue pipe elements. It is also
possible to secure the pipe to the flue gas spigot
(provided with a hole) with a short pin (nail or rivet). It is
imperative to ensure that the flue pipe does not
protrude into the free cross section of the chimney (see
Figure 13). To insert the pipe in the chimney, the use of
wall lining is recommended. Flue pipe connections of
neighbouring rooms must be connected to the chimney
with at least a 50 cm stagger (see figure 13).
Wrong
With longer flue gas pipe configuration (maximum 3 m)
horizontal sections must be avoided: piping that rises in
the direction of the chimney is recommended (e.g. 15
cm per metre). The flue gas line should have the same
diameter over its entire length (120 cm), constrictions
should be avoided. Please use as few flue pipe bends
as possible. Insulate flue pipes that pass through an
unheated room.
With unfavourable draught conditions (insufficient
delivery pressure) it is advisable to connect the
appliance by way of a so-
called “starting section” of at
least 1 m height. (see Figure 15). The use of insulated
flue pipes is also advantageous.
10. Electrical connection of the oil stove
If your oil stove is equipped with an electric ignition you
will require a power socket (230 V, 50 Hz) preferably
near the stove for connecting this electric ignition. The
stove is equipped with an approximately 1.2 m long
connection cable with power plug. To prepare the
electric ignition it is merely necessary to plug in the
power plug.
Caution!
The socket for the appliance plug must not be
located behind the appliance so that unobstructed
access to the plug is ensured.
The electric ignition consists of: ignition transformer
(see Figure 16), fork toggle switch (mounted on the oil
controller), bimetal switch (attached to the inner stove,
see Figure 17), ignition bar (see Figure 24) and various
cables.
