3.2
Installation Room
Wodtke Pellet Primärofen furnaces may only be
installed in
residential spaces
with ordinary im-
purities, normal relative humidity (dry rooms ac-
cording to VDE 0100) and with
room tempera-
tures from +5 °C to +30 °C
(environmental tem-
peratures during operation).
The furnaces are not splash-water protected and
may not be installed in wet rooms. Due to the op-
erating and flame noises of the furnaces, we do
not recommend installation in bedrooms or relax-
ation rooms. Operating sounds, such as pellets
dropping and flame/air current and drive motor
noises, are audible during operation. In tempera-
tures of <5 °C (e.g. in summer cottages), certain
minimum settings must be made on the furnace
and appropriate frost protection devices (e.g. elec-
trical heat monitors) must be provided for. Safety
equipment can be effective in operation at temper-
atures >30 °C. Please observe the respective no-
tices on heating operation in the unit's instructions.
The installation room or combustion air connection
for all furnaces must have at least 4 m³ of volume
per kW nominal heating output: 6 kW
24 m³.
Please observe the specifications on fire protec-
tion regulations.
The furnaces must be installed on
a sufficiently load-bearing and non-flammable
base. At least 20 cm of free space must be avail-
able to the rear and sides of the furnaces after in-
stallation for assembly work. Please also note that
the units should be equipped by the customer with
flexible connections (electrical lines) so that they
can be subsequently moved for possible assembly
work / repairs and are easily accessible.
3.3
Connection of External Con-
trollers
All units can be conveniently and easily activated
and deactivated by hand. In addition, wodtke of-
fers
compatible room and clock thermostats
for
automatic activation of the units (see price list).
Solid fuels, such as wood pellets, require
more
time for ignition than liquid or gaseous fuels.
The ignition process leading to the first flame al-
ready requires several minutes and
the furnace's
full output is not available until about 15
minutes after starting
, when the warm-up pro-
gramme is complete.
When the furnace is shut off, it also takes sev-
eral minutes
- in contrast to oil or gas furnaces
- until all pellets have been burned and the
flame goes out.
Consequently, a
fan stop delay
of several minutes is programmed into the fur-
nace, which should elapse before the furnace is
restarted.
Due to the required warm-up programme and
the fan stop delay, there is therefore less out-
put available during frequently cycling opera-
tion in comparison to oil or gas furnaces.
In the case of automatic activation of the units with
other controllers
, a
minimum unit run time of
30, preferably 60 minutes
should be observed.
This means that the controller must be configured
so that
too-frequent cycling (on-off) of the unit
is prevented.
The
hysteresis of the external
controller
should be selected to be large enough
that at least 15 minutes pass for the fan stop delay
between the "shut-off" and "restart" signals.
For installation of the required electrical connec-
tion lines, we recommend two empty conduits with
at least Ø 30 mm be provided by the customer
(separated into empty conduit for 230V and 24V
connection lines).

Important Notices Regarding
Room Air Dependent and
Room Air Independent Oper-
ation
3.4.1
General Notices
Please always observe the respective local regu-
lations and rules, in consultation with your author-
ised district chimney sweep. We can accept no li-
ability for changes which occur after printing of
these instructions. We reserve the right to make
changes without notice.
3.4.2
Room Air Dependent Operation
The furnace is standard-delivered as a room air
dependent pellet furnace. That is, the furnace ex-
tracts all of the combustion air from the installation
room via the central air intake on the rear side of
the furnace. A sufficient combustion air supply is
mandatory (approx. 25 m³/h at full output).
