- in the fi re safety area: STN 92 0300;
- for installation and fi tting (and repairs): STN EN 1755 or STN
38 6460, as applicable STN 38 6462, Decree no. 48/1982
Coll. (as amended by the later prescriptions) and the binding
occupational health regulations;
- in time of running and operation: STN 38 6405;
- in the area of discharge of combustion gases and air infl ow
STN EN 483, company material – “catalogue of dual piping for
discharge of combustion gases and infl ow of combustion air
designated for type C gas appliances, i.e. in closed “TURBO”
version.
Local Regulation2.4.2
The boiler is designated for operation within the normal AA5/
AB5 environment in compliance with STN 33 2000-3 and
STN 33 2000-5-51 (i.e. a temperature range of 5 – 40°C,
temperature-dependent humidity to a max. of 85%).
PANTHER boilers are suitable for the conditions of zones 1, 2
and 3, in rooms with a bath or shower and in washing areas as
set out in STN 33 2000-7-701; they may not be installed in zone
0 (Fig.8). Before installation in the areas mentioned, protection
against electric shocks must be provided for according to the
same norms.
The boiler complies with Ministry of Health Decree No 13/1977
Coll., i.e. on noise, for installation in residential and public
areas.
The boilers are built to operate with heating water, in
compliance with STN 07 7401. (Above all, the water must never
be acidic, i.e. its pH must be higher than 7 and it should have
minimal carbonate hardness.)
The requirements regarding the characteristics of domestic
water are set out in STN 83 0616 (potable water STN 75
7111). With regards to water with total material concentrations
of calcium and magnesium greater than 1.8 mmol/l, further
“non-chemical“ measures against scale deposits (e.g. operation
of magnetic water treatments in combination with settling
equipment) are advisable.
Silting up of the boiler with contaminants from the heating
system or the settling of boiler scale on these disturbances, or
on induced disturbances (e.g. silting up of the exchanger, pump
breakdowns) are not covered by the boiler warranty.
The distance from fl ammable materials (e.g. PVC, fi breboard,
polyurethane, synthetic fi bres, rubber etc.) must be suffi cient to
keep the surface temperature of these materials below 80°C.
The minimum working (unhindered) space in close proximity
to the boiler must be such that the boiler can be worked with
easily and safely with bare hands and with the usual hand tools;
we recommend a minimum distance of 300 mm from up and
under, 10 mm from side and a minimum of 600 mm in front of
the boiler.
CH (heating) + HW (hot water) -
The GEPARD boiler (model MTV and MOV) supplies both
central heating and hot water for the home.
Non-condensing boiler with exhaust vented to a chimney -
Model MOV must be fi tted to a ventilation system (chimney).
The boiler comes equipped with a safety device that shuts off
the gas feed if the chimney becomes blocked.
Non-condensing boiler with forced extraction of exhaust. -
The MTV model is gas models fi tted with a ventilation system
for the intake of air and the venting of exhaust. Thanks to this
ventilation system, the heater can be installed in any space.
If the ventilator fails or if the chimney becomes blocked, the
pressure switch shuts down the heater.
The boiler must be installed and commissioned by a qualifi ed
technician. This ensures proper installation and operation
in compliance with valid norms. If any maintenance, repair
or adjustments concerning the gas are needed, a qualifi ed
technician must be called.

Recommendations before you install5.2
Nominal pipe internal diameter is chosen in the usual way,
using the pump characteristic. Distribution pipes are designed
according to the requirements for the system performance, not
according to the boiler’s maximum output. However, measures
must be taken in order to ensure suffi cient fl ow so that the water
temperature difference in the supply and the return pipe is less
than or equal to 20˚C. Minimum fl ow must be 400 l/h.
The piping system construction must prevent air bubbles from
developing, making permanent bleeding of the system easier.
Bleeding valves should be situated on all high points of the
system and on all radiators.
It is recommended to install upstream the boiler a set of heating
water, hot water and gas isolation valves.
It is recommended to install upstream the boiler a set of heating
water, hot water and gas isolation valves.
At the lowest point of the heating system we recommend
installation of an exhaust valve, which shall also serve for fi lling
of the heating system.
Before fi nal installation of the boiler, the heating distribution
system pipes must be fl ushed a few times with pressurised
water. In old, already used systems, the fl ushing must be done
in the direction opposite to the fl owing heating water.
Important: Before connecting the boiler to the heating system,
remove the plastic plugs located inside all connection outlets.
Before installing a new boiler, it is essential to clean the
system thoroughly. In old systems it is necessary to remove all
sludge settled at the bottom of radiators (predominantly gravity
system).
In new systems it is necessary to remove all conservation
material used by majority of radiator manufacturers.
It is recommended to install upstream the boiler (i.e. on the
heating water return pipe) a sludge separator. The sludge
separator should be constructed in such a way that it is easy to
empty at regular time intervals without the necessity to drain a
large quantity of water from the heating system. The separator
can be combined with a fi lter, but a fi lter with a sieve alone is
not suffi cient protection. The fi lter and sludge separator must be
checked and cleaned regularly.
During reconstructions, in adverse building arrangements
and so on, the boiler may be connected to the CH heating
system, the HW system and the gas inlet with fl exible elements
(hoses), but only those designated for this purpose. If fl exible
elements are used, these should be as short as possible and
must be protected from mechanical and chemical stresses and
damages. It must also be ensured that before the end of their
life cycle or reliability in maintaining their parameters (according
to their manufacturers’ data) they are always replaced by new
ones.
Note: The boiler includes fi lter which is situated below the HW
fl ow sensor. You have to take out the HW fl ow sensor with fi lter
to clean up the fi lter.

INSTALATION
Mounting the boiler 5.4
When mounting the boiler on the wall, proceed in accordance
with the installation design conditions (e.g. wall load bearing
properties, chimney inlet, pipe inlet and outlet connections).
The mounting procedure:
Take the paper template and attach it (for instance by - adhesive tape) to the place of installation. When positioning
the template, user a plumb line or a spirit level.
Using the marked points on the template, drill all necessary - holes (mounting bar, connecting ramp).
If combustion gas discharge is to be directly via the building’s - façade, project and mark a point for a pass of the concentric
ducting.
Remove paper template. -
Drill the required holes, respecting the diameters shown in - the template.
Insert wall plugs into the holes for the mounting bar and then - fasten the bar properly with the screws provided.
Hang the boiler on the mounting bar. -
Install the combustion gases removal ducting onto the boiler. - Fill-in the gaps between the ducting and the wall opening
with a non-fl ammable material.
Remove the plastic plugs from the boiler outlets. -
Install the protective fi lter to the heating water inlet (not part - of delivery).
Mount isolation valves on all outlets from the boiler (not part - of delivery).
Connect heating water, hot water and gas distribution pipes - to the isolation valves.
Install lever for topping up water into the heating system. -
Fill boiler with water. -
Perform check of tightness of all connections. -

Hydraulic connection6
The boiler connection terminals may not be placed under
undue pressure from the piping system for the CH circuit, the
HW circuit or from the gas intake. This assumes a precise
observance of the dimensions of the endings of all connecting
pipes, with regard to height as well as distance from walls and
separation distances of the interconnected individual intakes
and outlets.
The heating system circuit should be connected to the boiler in
such a way that during repairs to the boiler the heating water
need be released only from the boiler.

INSTALATION
Regulations 7.1
The type MOV is designed for combustion gases to be removed
and discharged into a chimney (through a chimney inlet) with
a minimum stabilised thrust of 2 Pa. The boiler is connected to
the chimney inlet by a fl ue of a diameter corresponding to the
size of the boiler’s gas exhaust outlet. It is forbidden to place
inside the combustion gases exhaust ducting any objects which
impair the combustion gases fl ow (e.g. various types of heat
exchangers to utilise their residual heat). The combustion gases
exhaust ducting is not part of the boiler accessories.
Construction of the combustion gases exhaust ducting as well
as that of the chimney must comply with relevant requirements.
Compliance with the requirements specifi ed by these standards
will prevent undesirable phenomena from occurring, such as
excessive cooling of the combustion gases, penetration of
dampness into brickwork and fl uctuations in the chimney thrust,
and thus prevent undesirable effects on the boiler’s functioning.
The boiler takes combustion air from the space in which
it is installed. Air must be supplied in suffi cient quantity in
accordance with applicable regulations.
Venting of exhaust and drawing in of combustion air for the
MTV type is done only through designated pipes.
The level sections of the piping slope at a gradient suffi cient to
let the condensation drain towards an outside area or towards
a receptacle designed to draw off condensation. To achieve
this, the elbow joint may be gently bent away from the straight
section. The upright sections of the piping are always fi tted with
devices to draw off condensate. The devices for drawing off the
condensate are installed where possible close to the passage
where the exhaust exits the boiler. Breakdowns caused by
leaking condensate are not covered by the boiler warranty.
Description exhausting kits7.2
Methods of air and fl ue gas ducting 7.2.1 (according to STN EN 483) and permitted
piping lengths
If not described otherwise for the individual following methods
of placing coaxial pipe routes and their drainages, the piping
lengths (from connection at the boiler to the drainage) can be
set as in the following cases.
Note: One Em is considered as either a 1 m direct section or
one 90° joint.
Caution: If the lengths described for individual types are
exceeded, the exhaust diffuser (orifi ce) must be removed from
the ventilator drain.
The following methods of air intake and exhaust venting are
recommended for the boiler:
The C7.2.2 12 method (MTV)
Level routes and level venting into an open area.
Length of fume ducting (23 MTV):
60 / 100: min. 0.3 m (with one 90° joint), max. 3 m (with one - 90° joint).If the total fume ducting length is more than 0.5 m,
the diffuser with a diameter of 39 mm must be removed.
80 / 125: min. 0.5 m (with one 90° joint), max. 9 m (with one - 90° joint).If the total fume ducting length is more than 1 m,
the diffuser with a diameter of 39 mm must be removed.
An example of a level coaxial pipe route: version C12 (complies
with STN EN 483)
The C7.2.3 32 method (MTV)
Vertical routes and vertical venting into an open space.
Length of fume ducting (23 MTV):
60 / 100: min. 1 m (with one 90° joint), max. 4 m (with one - 90° joint). If the total fume ducting length is more than 1.5 m,
the diffuser with a diameter of 39 mm must be removed.
80 / 125: min. 1 m (with one 90° joint), max. 10 m (with one - 90° joint). If the total fume ducting length is more than 1.5 m,
the diffuser with a diameter of 39 mm must be removed.
An example of a vertical coaxial pipe route: version C32
(complies with STN EN 483)
The C7.2.4 42 method (MTV)
Connecting to a double shared chimney.
Double piping from independent boilers (independent routes)
can feed into shared chimneys; the transport capacity of the
chimney is judged according to the manufacturer’s data on the
chimney. If the pipes are set into the chimney in two directions
and vertically aligned, there must be a vertical separation
between the outlets of at least 0.45 m. Where two outlets vent
towards each other, they must be separated by a minimum
vertical distance of 0.6 m. The exhaust piping into the shared
P2_GEPARD_installer manual_ work basis_EN_02 - 03/10 - protherm - 15 -
INSTALATION
double chimney never has terminal elements — the same as
with pipes that vent into open areas!
Both components of the route — external (air) and internal
(exhaust gas) — must safely feed into the relevant chimney
duct but not protrude so deeply that they create blockages in
the exhaust or air ducts.
Length of fume ducting (23 MTV):
60 / 100: min. 0.3 m (with one 90° joint), max. 3 m (with one - 90° joint). If the total fume ducting length is more than 0.5 m,
the diffuser with a diameter of 39 mm must be removed.
The C7.2.5 52 method (MTV)
Separate double piping and venting into different areas (with
different parameters, mainly of pressure)
For venting exhaust and bringing in air for combustion, separate
piping may be used. The separate piping may not be routed on
opposing walls of the building.
Length of fume ducting (23 MTV):
80 / 80: min. 2 x 0.5 m, max. 2 x 18 m. If the total fume - ducting length is more than 2 x 2 m, the diffuser with a
diameter of 39 mm must be removed.
The C7.2.6 82 method (MTV)
Using piping in cases where the air is drawn in from an open
area and the exhaust vents into a shared chimney.
Length of fume ducting (23 MTV):
80 / 80: min. 2 x 0.5 m, max. 2 x 18 m. If the total fume - ducting length is more than 2 x 2 m, the diffuser with a
diameter of 39 mm must be removed.
Air may in the same way be brought in from an open space (or
a space well supplied with air) and exhaust extracted into a
common chimney (or, again, into a space with common venting
of exhaust gases). The special case of B22 also belongs in this
category. (See following text.)
The B7.2.7 22 method (MTV)
Extraction of exhaust (also in separate piping) into an open
area and intake of combustion air from an internal space in the
building in close proximity to the boiler (in coaxial piping with the
perforation of its outer part).
Length of fume ducting (23 MTV):
80 / 80: min. 2 m, max. 2 m. The diffuser must be removed. -
When drawing in air for combustion from internal areas of the
building, a suffi cient quantity of that air must be ensured. No
other appliance may be connected to the exhaust duct (whether
chimney or pipe), and when drawing in air at least 1.2 m3 of air/
hour per kW of boiler output must be available.
P2_GEPARD_installer manual_ work basis_EN_02 - 03/10 - protherm

INSTALATION
Piping gradient7.2.8
The layout of the piping must permit a down-gradient of the
exhaust piping towards the boiler at a nominal gradient of 3
percent. A device for drawing off condensate must be placed on
the piping as close as possible to the boiler.
Safety measures7.2.9
The distance of fl ammable materials from the exhaust
component of the separate piping must be enough to ensure
that the temperature at the surface of these materials is no
higher than 80°C.
Exhaust may not be vented in areas:
where a danger of explosion is present (as set forth in STN • 33 2320)
that are interior areas of a building (lofts, halls, stairwells • etc.)
closeable, i.e. passages or gateways etc.•
that descend underground (even if these remain open to • the surroundings and free of obstructions), e.g. tunnels,
underpasses etc.
These basic injunctions for venting exhaust must always take
adequate account of where independent air intakes are sited.
Wall apertures for coaxial piping for drawing in air and venting
exhaust are cut to the appropriate size (approx. 120 to 150
mm) and sealed (with building construction methods) following
the installation. Non-fl ammable materials (with Degree A
of fl ammability according to STN 73 0823) must be used
for sealing, e.g., masonry mortar, plaster etc. Openings in
combustible walls or roofs must be made according to the fi rst
section of this part.

electrical plugs fi tted involved.
External leadership must be grounded with the right polarity and
in accordance with current standards.
The manufacturer assumes no liability for personal injury or
other damage caused by improper grounding of equipment.
This applies also non-applicable standards.
Hooking up the boiler to the mains voltage is done through a
triple-wire plug with a fl exible cord. The socket for connecting
the boiler to the electrical network must comply with STN 33
2000-4-46. It must always have the protective ground (pin)
reliably connected with the PE or PEN wire (a combination
of green and yellow colours). The boiler must always be
connected through its main to the ground and must always be
installed in a way that allows access to the socket and plug.
The use of a variety of “adaptors”, “extension cords” etc. is not
permitted.
Caution: The preparation of plugs and sockets as well as room
regulator connections that extend into the interior electrical
components of the boiler must under all circumstances be
carried only by a person with electrotechnical qualifi cations as
set forth in Decree No. 50/1978 Coll. In the same way, servicing
of the electrotechnical components may be carried out only by
a person with the above-mentioned professional qualifi cations.
Before servicing the electrotechnical elements the boiler must
be disconnected from the current by pulling the mains lead from
the socket!
The main body of the boiler is protected by a tube fuse (T 2A /
250 V), which is located on the boiler control board.
