Protherm Leopard 24 BOV User And Installation Instructions Manual - Introduction
17
24 BTV/BOV is compatible with all
common types of heating water systems
and radiators.
24 BTV/BOV boiler can be put into opera-
tion only by an authorised installer in com-
pliance with valid regulations. A network
of the manufacturer’s con trac tu al service
centres provides installation, maintenance
and repairs.
The boiler is designed for operation in a
normal environment (temperatures be-
tween +5 and +40°C, humidity up to 85%,
depending on the tem per a ture).
The boiler is suitable for installations in
residential and social rooms as regards
the noise level.
The heating-circuit water must comply
with the relevant Standard (it must not be
acidic, i.e., its pH must be above 7, and
the carbonate hardness must be as low
as possible).
Use of anti-freeze mixtures is not recom-
mended, since they have properties unsuit-
able for boiler operation. These specifically
include: reduction of heat transmission to
the heating circuit, high thermal expan-
sion of volume, ag ing, de te ri o ra tion of
rubber parts. Even if no other solution for
preventing the system from freezing has
been found, con se quent failures to meet
the operational parameters and/or defects
caused by the use of the anti-freeze mix-
tures will not be covered by the warranty.
Prior to the final assembly, the heating-cir-
cuit pipes should be flushed by pressure
water, several times. For old er cir cuits (that
have already been in use) the flushing
stream direction must be opposite to that
of the heating wa ter.
Installation of a sludge separator is recom-
mended in the incoming branch of heating
water. The design of the sep a ra tor should
enable regular removal of sludge without
necessity to discharge large quantities of
heating wa ter. The sludge separator can
be combined with a filter; however, a filter
itself is not sufficient protection. Both the
filter and the sep a ra tor should be regularly
checked and cleaned.
The relevant standards provide re-
quire ments for the water quality: if the sum
of calcium and magnesium concentrations
is above 1.8 mmol/litre, other “non-chem-
i cal” measures should be taken against
scaling (such as protection by magnetic or
electrostatic field).
The warranty does not cover mechanical
defects caused by foreign bodies and
impurities (e.g., a clogged ex chang er or
pump).
Working temperature of the upper parts
of the boiler (especially the top and side
panels) may be up to 50°C high er than the
ambient temperature. The clearance from
flammable materials (such as chipboard,
polyurethane, polystyrene, polyethylene,
ex pand ed PVC, synthetic fibre, cellulose,
asphalt board, rubber, etc.) must secure
temperature these materials under 80°C.
The minimum handling space around the
boiler should be such that easy and safe
work with bare hands and/or with tools be
possible.
