INSTALLATION INSTRUCTIONS
The stove is designed with rear flue connection. The stove is delivered with two flue connections
allowing both direct horizontal connection and vertical connection. Selected flue connection shall
be screwed tightly tigtly to the outlet on the rear side of the stove with two M6 screws and nuts.
In case of direct (horizontal) connection, only part no. 119 will be installed, while in case of vertical
connection parts 117, 118, 119 – Figure 5 – should be installed subsequently. The stove is
delivered complete with a bag containing all necessary screws and nuts.
Install the front plinth (104) as shown on the figure on the cover page.
A spring may be installed on the lower hinge of the stove door to make sure that the door will not
remain open, except when firing or refuelling.
Figure 1
This is important to prevent the smoke from the firebox from entering the room when more
than one unit may be connected to a chimney in poor maintenance condition.
To install the spring, proceed as follows:
-Close the door, remove the front plinth, remove the pin from the lower hinge, insert the screw
to protrude some 15 mm from the hinge. Fix the spring onto the screw and pull it at one end to
engage the door edge. While holding the spring in the position, press the screw down and fix it
with the nut (see Figure 1).
Enable access on the back of the fuel fireplace because of maintenance (on the connection
of the conduits of the central heating with the cattle).
Connecting the boiler into the central heating system
The boiler has to be connected into the central heating system with open expansive container so
that, in case of over-heated water, there would be no elevation of pressure in the system
(illustration 1). We suggest installation of a 4-tine mixer (so-called ‘mouse valve’) which allows
regulation of temperature of the boiler water and secures it to be hot enough (60 – 70°C) in order
to avoid boiler perspiration and prevent low-temperature corrosion. A thermostat can be installed
instead of ‘mouse valve’ with its sensor on the flow pipe. The thermostat engages the pump only
when the water reaches sufficient temperature in the boiler and the flow pipe. Illustrations 1 and 2
show connection of boiler into the central heating system. The H height secures sufficient
pressure in the system in order to achieve good circulation through the heating bodies. A water
boiler can be installed into the system (it is advisable to do so). A boiler can secure natural
(gravitational) circulation independent of the pump. The water boiler is to be installed above the
fireplace level with as low water circulation resistance as possible (short pipes with elevation
towards the boiler).
Prior to putting into operation (prior to first firing), check if the heating system is filled with water
and well aired. Open all shutters. Engage the circulation pump.
