burning process makes the path of the fumes to the chimney short, which automatically generates
better draught. closing it by means of the lower damper handle (15) means directing the fumes
between the two deflectors – the lower (26) and the upper (25) one (smoke shelf ), which makes the
fume path longer. drawing 7.; thanks to which the burning of fuel particles which have not been bur-
ned earlier in the combustion chamber (1) takes place in the space between the deflectors and above
the steel deflector. additional heat gained in that way is transmitted to the vertical water heater fire
tubes (17) and to the water jacket (system) (16). damper (13) handles (15) are equipped with gradual
damper position adjustment.
The water jacket (system) (16) is equipped with fixed stub pipes which are used to connect it to the
heated water central heating system, thermal sensors and the excessive heat transmission system
– the heating coil (24). The stub pipes (20) and (19) with 1 inch female thread (G1'') are intended for
connecting the insert to the central heating system (the right and the left side of the insert – cross
connection for supply/return recommended). The stub pipes (19) with 1 inch female thread (G1'') fit-
ted in the lower part of the water jacket (system) (16) are intended for connecting water return from
the central heating installation. The stub pipes (20) fitted in the upper part of the jacket are intended
for connecting heated water outlet to the central heating installation (the right and the left side of
the insert – cross connection for supply/return recommended).
stub pipes with male thread (G1/2'') (23) constitute the heating coil (24) ends. The stub pipe of the
thermal valve sensor (22) with female thread (G1/2'') is intended for connecting the capillary tube of
the safety valve thermal sensor which controls water flow activation through the heating coil (24).
The heating coil (24) is an element that protects the water jacket against overheating. If heat trans-
mission through the central heating installation is lower than the capacity generated by the insert,
the water temperature in the water jacket may rise to a dangerous level. In such a case, when the
temperature of 95ºc +/- 2 ºc is exceeded, the thermal valve opens water flow through the heating
coil, which cools the water in the water jacket (system). The element (21) is the mounting socket of
the fireplace controller thermal valve, which controls the operation of the system (central heating
pumps) and of the optional air throttling valve. such a throttling valve is mounted in the air supply
channel from outside of the building and controls the amount of air drawn through the fireplace; it
provides optimization of the burning process.
Attention!
Fireplace inserts with water installation are designed to work as a source of heat in open and closed
water heating systems with adequate protection, where the acceptable supply water temperature
does not exceed 100°c, the acceptable working pressure is not higher than for the applied devices
and the circulating water is used for heating purposes only and cannot be taken away from the
system.
Kratki.pl inserts can work in both open and closed systems of central heating installations.
Working pressure in a closed system is 2 bar.
