smoke pipes is assembled on the upper side. The lid and the coupling are connected via
bolts.
In case you want to set the smoke drain on the back side, unscrew the bolts which
connect the drain lid and the back side of the stove and fi x the smoke drain coupling at
that location. Connect the lid with the plate-frame via bolts (position 24) at the envisaged
place. Take care that the sealings which are located on the lid and the coupling are in
cannals and suffi
ciently tightened so that the smoke does not pass.
Connecting the cauldron to the central heating system
Thermo Lava has a cauldron with a pipe exchanger which has been made from
high-quality cauldron steel. The couplings for water are pipes of 1”, made from the same
material.
The stove is primarily intended for
heating via separation of warm water. For the
intake and the exhaust of the water into the
system the couplings of 1’’ on the cauldron
are envisaged. The stove can be assembled
on to the open or closed heating system,
as shown on the pictures 3, 4 and 5. For the
closed system there are two recommended
ways of connection, depending from the
pump position.
Inherent part of the derived installation
is the valve for thermal exhaust which serves
as a thermal fuse for possible overheating.
Valve for thermal exhaust Caleffi
544 ½ which
is shown on the picture 2 is recommended.
Valve for thermal exhaust with double
eff ect is great at solving safety problems in
heating installations for stoves and fi replaces which use solid fuel as a source of heat.
This is a device which contains a valve for thermal exhaust and a valve for charging, the
two acting simultaneously on the remote sensor control. This device is connected to the
exhaust and hydro network (charging) while achieving critical temperature and creates
circulation of cold water in the system until the temperature decreases under the value
to which the sensitive element reacts. At that moment, the exhaust and the charging are
simultaneously closed. This is how the device also functions in the case of the sensitive
element’s breakdown.
Note: Thermal fuse is not a part of the product and is not delivered with the product.
Guarantee for the stoves is valid exclusively with the installed thermal fuse..
With the both ways of assembly to the closed central heating system, a closed
expansion vessel. The volume of this vessel is determined on the basis of the cauldron
capacity, and the set ratio is 1kW : 1l. the volume of the expansion vessel is determined as
V = 0,07xV water [ l ] ,
Where Vwater is the volume of water in complete facility.
