15. STOVE STORAGE
After finishing the stoking season, the stove should be cleaned from ash and smoke. Water should be
released only in case when some repair of the installation should be performed. If the installation is not used
in the heating season, pour a certain quantity of some antifreeze liquid or release the water from the
installation as a protection from freezing.
16. FAULTS
Table 3
RB Faults
Possible cause
Elimination
1
Water pressure in
installation is slowly
decreasing
The installation does not seal
Check the sealing of welded
connections, threaded fasteners,
nuts etc.
2
Cold radiators on the
highest installation point
and a sound is heard
Air in the installation and low
pressure in the installation
Increase pressure in the installation
and release air from the installation
and from radiators
3
The radiators do not
heat along the entire
length
Air in radiators
Release air from radiators through
the vent valve
4
The safety valve drains
water from the
installation, and the
pressure is less than 3
(2,5) bar
Safety valve failure
Replace safety valve
5
The pressure in the
installation is more than
3 (2,5) bar and the
safety valve does not
drain water from the
installation
Safety valve failure
Replace safety valve
6
Sudden water
temperate increase in
the installation
Air in the installation
Perform radiator venting
Closed valves towards radiators
Open all valves in the heating
system and provide normal water
circulation in the installation
Circulation pump failure
The circulation pump should be
repaired or replace it thereby
allowing operation of the heating
system
Electrical power loss
You should open all valves that
reduced the heating system. This
mostly refers to the “by-pass”
valve.
Stop or reduce stoking with strong
control so that the water
temperature in the system would
not exceed 90
C until electricity
arrives.
7
Sudden pressure
increase in the
installation while water
temperature increase
Decreased pressure in the
expansion vessel or completely
empty. Remove the cover or the
vessel valve cap and release some
air through the valve. If the
membrane is destroyed, water
shall leak from the valve, and if it is
only half-empty, only air will come
out
If water is leaking from the valve,
replace the expansion vessel.
If only air comes out from the
valve, remove the installation
vessel and pump it. The pressure
in the vessel must be equal to or
greater than height difference of
the highest and lowest installation
point. Example:
For height difference of 5m. the
pressure is Pmin.
0,5 bar.
