cium and magnesium concentration greater
than 1.8 mmol/l, it is useful to implement other
“non-chemical” measures against incrustation
(e.g. magnetic water treatment combined with
a desludging device).
Problems caused by clogging of the system
with dirt from the heating system or incrustation
sediments or clogging-induced problems (e.g.
clogging of the heat exchanger, pump defects)
are not cover by the boiler’s warranty.
The PROTHERM Tiger 24 (12) KTZ a 24 (12)
KOZ boilers are compatible with common typ-
es of HoW heating systems and heating radi-
ators.
Important:
PROTHERM boilers must be put
into operation by an authorised organisation
only, according to Czech Bureau of Occupatio-
nal Safety and Czech Safety Inspectorate Noti-
ce No. 21/1979 (in the wording of Public Notice
No. 554/1990).
The boiler must be put into operation and war-
ranty and post-warranty service performed by
the manufacturer’s contracted service organi-
sation which meets the above specified requi-
rements.
The boiler is designed to work in an normal
AA5/AB5 environment according to STN 33
2000-3 and STN 33 2000-5-51 (i.e. within tem-
perature range +5 to +40 °C, humidity depen-
ding on temperature, not exceeding 85%).
The 24 (12) KTZ a 24 (12) KOZ boilers are
suitable for the conditions of zones 2 and 3
(Fig.10), in rooms with a bath tub or shower and
washing rooms according to STN 33 2000-7-
701; they may not be installed in zone 0. When
installed in one of the above rooms, the boiler
must have a protection against electric shock in
accordance with the same standard.
The boiler may be (according to Ministry of He-
alth Notice No. 13/1977, i.e. by their noise level)
installed in residential and communal rooms.
The boilers are designed to run with heating
water compliant with STN 07 7401 (which un-
der no circumstances can be acidic, i.e. its pH
factor must be greater than 7 and must have a
minimal carbonate hardness).
Requirements on utility water properties are
defined by STN 83 0616 (on drinking water by
STN 75 7111). If the water has a sum of cal-

Distance from flammable materials (e.g.
PVC, chipboard, polyurethane, synthetic
fibres, rubber and other) must be suffici-
ent so that the surface temperature of the-
se materials does not exceed 80 °C. The
safe distance for reaching this highest
temperature must be observed regardless
of the flammability grade of a specific ma-
terial according to STN 73 0823. No flam-
mable materials may be placed on the bo-
iler (permanently or temporarily) or in this
safe distance.
Important:
Surface temperature of the
boiler upper parts (particularly the side
walls and the cover) of a working boiler
might exceed the ambient temperature by
up to 50 °C.
