Introduction
The Lion boiler is compatible with standard
types of hot water heating systems and
heating radiators, except systems with an
open expansion vessel.
Important:
Lion boilers must be put into
operation by an authorised organisation
only, according to Czech Bureau of
Occupational Safety and Czech Mining
Inspectorate Notice No. 21/1979 (in the
wording of Public Notice No. 554/1990).
The boiler must be put into operation
and warranty and post-warranty service
performed by the manufacturer’s
contracted service organisation which
meets the above specifi ed requirements.
Important:
The technician who puts the
boiler into service must show the user
all boiler functions, its controls, and if
necessary explain anything the user does
not understand in the User’s Guide which
is part of the boiler delivery.
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 temperature range +5 to +40°C,
humidity depending on temperature, not
exceeding 85%).
The Lion boilers are suitable for the
conditions of zones 1, 2 and 3, 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 (Fig.
8). 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 Health Notice No. 13/1977, i.e. by their
noise level) installed in habitation and
communal rooms.
The boilers are designed to run with
heating water compliant with STN 07
7401 (which under 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 defi ned by STN 83 0616 (on drinking
water by STN 75 7111). The reticulated
water should have in accordance with the
Public Notice pH factor within the range
6.5 to 9.5, and must have a minimum value
of acid neutralisation capacity KNK 4.5 ≥
1.0 mmol/l and CO2 (total) ≤ 44 mg/l.
If the water has a sum of calcium 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.
