3.4.3
Room
Air
Independent
Operation
The required combustion air is supplied to the fur-
nace directly via a sealed connection line from the
outside, and not extracted from the installation
room of the heating system.
The furnace is suitable for room air independent
operation (DIBt approval). The following must be
observed:
The combustion air line and the flue
pipes must be sealed.
In addition, a negative pressure no
greater than 8 Pa relative to the outside
may occur in the installation room, the
residence or a comparable usage unit
due to room air extracting systems.
The general building approval by the DIBt is num-
ber
Z-43.12-240.
3.4.4
Combination
with
Controlled
Venting and Ventilation Systems
If the furnace is installed in the effective range of
a controlled venting and ventilation system, §4 of
the fire-heating installations ordinance (FeuVo)
applies in Germany. The following options there-
fore exist, among others, for operation of the fur-
nace in combination with room air technology sys-
tems:
A room air independent connection or
operating method must be ensured (see
above).
The exhaust gas routing must be moni-
tored by special safety equipment (this
can be done with the wodtke differential
pressure controller DS01, for example;
see price list).
Use of a ventilation system which en-
sures that negative pressures no greater
than 4 Pa relative to the outside occur in
the installation room and that the re-
quired combustion air (approx. 25 m
3
/h)
is additionally supplied for the heating
system.
3.5
Chimney Connection
A chimney calculation must be performed before
installation (EN 13384). The chimney provides for
the safe removal of flue gases from the furnace,
particularly in case of power failure, and is thus re-
sponsible for an important safety function and
must be properly sized. In the case of a chimney
draught that is too high, we recommend installing
a draught limiter. The conveying pressure (= chim-
ney draught) must be between 3 Pa at minimum
and 20 Pa at maximum.
The heating system must be connected to a
chimney which is suitable for solid fuels. The
connection piece must be made of metal and
fulfil the corresponding requirements accord-
ing to the DIN / EN standard.
The
authorised
district chimney sweep
will be happy to advise
you in advance.
Additional safety equipment is required when
connecting Pellet-Primärofens to chimneys
which have multiple connections.
Please always observe the respective local regu-
lations and rules, in consultation with your
author-
ised district chimney sweep
. We can accept no
liability for changes which occur after printing of
these instructions. We reserve the right to make
changes without notice.
3.6
Combustion Air Connection
If the furnace is intended for room air independent
operation, the combustion air line must be gas-
tight. wodtke combustion air lines with sealing
rings (see wodtke price list) can be used for this.
To reduce cooling losses and to thereby save en-
ergy, wodtke has the special motorised flue gas
damper, which can be used an
intake and flue
gas damper
.
