4. INSTRUCTIONS

4.1 General information

The following directions and instructions concern questions of fundamental importance. It
is further presupposed that the installer of a heating plant has the necessary technical and
craftsman's basic knowledge for the task. This is naturally also the assumption where the
stove is being incorporated as an integrated stove into an existing system.
Heating stoves with heat exchangers are only suitable for closed systems with a heat sink.
Stoves without heat exchangers should be used with a heat sink.
The regulations according to EN 12828, EN 12831 and EN 12897 apply.
We do however recommend using the external heat sink in conjunction with a domestic
water boiler even for open systems, to control the stove's boiling function when there is a is
a limited heating requirement of hot water.

4.2 Important Notes

The heating stove must be put in place using a spirit level to ensure correct adjustment.
Threaded pipe connectors, straight or angled, should be used to for the flow and return
connections. Sleeves fittings or welding should not be used.
Horizontal pipe exits from the heating stove are to be in 1"-diameter. Reductions can only
be made in vertical connections.
The filling and emptying cock should always be located at the lowest point of the system in
the return connection.
Up to a static height of 10 m, the capacity pressure expansion vessel is dependent on the
water capacity of the system as follows:
Water content
Litre
up to 111
112 - 167
168 - 231
232 - 324
325 - 463
464 - 741
There should no manually operable shut off valves installed between the expansion vessel
and the stove.
A ventilation section at least 0.5 m above the highest circulation point in closed systems
with a diameter of at least 1" should be arranged and a ventilation valve provided at the
upper end.
In gravity systems the rise and fall of horizontal pipes should be at least 0.5 cm/m.
Radiators with more than 25 ribs or plate heat exchangers over 1.5 m long should be di-
agonally connected to the flow and return pipes.
