Starting up the boiler

Important:

Putting the boiler into operation and starting it up for the ﬁ rst time must be performed by an authorised service only!

If you wish to start the boiler up after it has been put into operation, make sure that:

1 the boiler is connected to the electrical

power supply;

2 all isolation valves (heating water, hot

water, gas) underneath the boiler are opened;

3 the heating water pressure is within the

recommended range of 1 – 2 bar Turn the main switch (Fig. 1, position 1). After a short time the heating water temperature appears on the display and the LED by the

symbol is lit (Fig. 1, position

2). After ignition of the burner the LED by the symbol

is lit (Fig. 1, position 6).In the event of a safety boiler shutdown the red malfunction LED

is lit on the

control panel (Fig. 1, position 5), and an

error code appears on the boiler display. Unblock the boiler by pressing the RESET button (Fig 1, position 9). If safety shutdown recurs after a short time again, or if the boiler cannot be unblocked by pressing the RESET button, call an authorised service organisation.

Shutting the boiler down

Switch off the main switch (Fig. 1, position

1). If the boiler is to remain shut down for a

longer period of time, close all cocks (heating water, hot water, gas) underneath the boiler. Shutting down the boiler must be performed taking into account the heating water temperature in the boiler and the surrounding environmental temperature in the given season of the year. In the case of danger that the boiler may freeze, discharge the water from the boiler, heating system and hot water distributors.

Starting up and shutting down boiler

Boiler control

Using the boiler without a room control unit

When running in this mode, the boiler maintains the selected heating water temperature. No room control unit is connected, the terminals for its connection must be mutually interconnected (standard factory setting).

Setting procedure:

• turn the main switch to the ON position;

• set the required heating water temperature on the control panel.

Operation of boiler with room control unit

In the case that a room control unit is used, it is necessary to set the maximum Heating Water temperature for which your

heating system has been designed, and which is capable of covering the thermal loss of the building even at low outside temperatures, on the control panel of the boiler (in order to prevent damage to the system). The process of heating the heating water can then be controlled by a control unit only up to the maximum value of the heating water you have set on the control panel of the boiler.

Note:

Thermostatic valves should not be ﬁ tted on the radiators in the room where the control unit is installed

Caution:

The manufacturer does not accept responsibility for damage caused by faulty setting of the boiler or room control unit.

On/OFF regulator

The boiler maintains the selected Heating Water temperature. Operation of the boiler is interrupted (switched on/off) according to the internal temperature of the room where the room control unit is installed.

Regulator with selected output modulation function

The room control unit regulates the output of the boiler into the heating system continuously on the basis of the internal temperature.

Operation of boiler with equithermal regulation

The boiler regulates the Heating Water temperature on the basis of changes in the outside temperature. In the case of this type of regulation it is necessary to use a regulator with an equithermal regulation function (Protherm Thermolink B,

Thermolink P or Thermolink RC) and connect an outside temperature sensor.

Caution:

By setting the maximum temperature of the heating water on the control panel of the boiler you may inﬂ uence the activity of equithermal regulation. In addition, the temperature of the heating water selected on the control panel of the boiler is also the limit temperature. In its requirement, the room regulator cannot exceed the temperature limit of the maximum permitted temperature of the heating water as set on the control panel of the boiler. Appropriate setting of the heating water temperature on the control panel of the boiler is one of the means of protection against exceeding the maximum permitted temperature into the heating system (ﬂ oor heating). Nevertheless, we recommend installation of the heating system with an additional safety armature, which shall prevent undesirable increases in temperature.

Protection functions

Setting boiler output

The factory setting of the boiler is to maximum output. In case of necessity it is possible to adjust the output of the boiler according to requirement (with regard to the properties of the boiler).

Important:

Change of setting of boiler output must be performed only by an authorised technician.

Protection against freezing

The boiler has inbuilt antifreeze protection, which prevents the boiler (but not the heating system and hot water distributors) from freezing. When the temperature of the heating water drops below 8°C, the pump is automatically started without regard to the requirement of the room control unit or without regard to the setting of summer mode. If the temperature of the heating water in the boiler rises and reaches

10°C, the pump is automatically switched off. If the temperature of the heating water continues to drop and reaches the temperature of 5°C, the boiler is started up and heats the heating water to 35°C.

Important:

During active function of antifreeze protection, the three-way valve is switched to central position, thus activating heating of the heating water and hot water.

Protection of hot water tank against freezing (for types KTO and KOO with connected external hot water tank)

When the hot water in the tank drops below 10°C, the boiler is automatically started and heats the tank to 15°C. This function is active only in the case of connection of an external tank equipped with an NTC sensor.

Pump protection

Switching the pump on for a short time (approx. 20 s) when it has been in the room continuously for 23 hours ensures protection against blocking or sedimentation when the pump has been idle for a longer period of time.

Important:

This function of the boiler can-

not be blocked.

Running down of pump

After heating of the hot water, the running down time of the pump is set at 30 s.

During heating of the heating water the running down time of the pump is set at 3 min. The maximum settable run down time of the pump is 60 min.

Important:

This function is active only in

the case of a boiler with mains voltage.

Anti-cycling

The boiler is equipped with an anti-cycling function. The time after which the boiler is switched back on is automatically calculated by the control panel with regard to the conditions in the boiler.

Disconnection of boiler from mains

Disconnect the boiler from the power supply only during service interventions or when boiler is idle for longer periods (see chapter “Shutting the boiler down” on page 8). Upon disconnection of the boiler from the power supply all protective functions of the boiler are deactivated.

Power failure

Power failure will turn the boiler off. When power supply is restored, the boiler will automatically restart itself without losing any of the operating parameters settings.

If the red LED (Fig. 1, position 5) is lit on the control panel after electrical power supply restoration, proceed according to the instructions in the section Starting up and shutting down boiler.

Note:

The boiler may be blocked as a consequence of overheating caused by the pump being switched off as a result of power failure. Rectify this fault by pressing the RESET button on the boiler control panel. If the fault persists call an authorised service.

Safety valve

The boiler is equipped with a safety valve with an opening pressure of 3 bar. DO NOT TOUCH THE SAFETY VALVE! Whenever the safety valve starts releasing heating water, switch off the boiler, disconnect if from the electrical power supply and call a service organisation. If the heating system repeatedly loses pressure, consult your service organisation.

Important:

All the mentioned electronic protection functions are enabled only when the boiler is connected to power supply (the power cord plug is inserted into a power socket and the main switch is in the ON position (I).

Service and maintenance

Toping up water to the heating system

Water to the heating system (only in small quantities) can be topped up through the boiler’s top-up valve (Fig. 3).

When topping up water, the following conditions must be met:

1. Pressure of the water being supplied to the boiler must be always higher than the pressure of the water inside the heating system.

2. When toping up water, the boiler must be cold (water temperature must not be higher than 30°C).

3. Recommended water pressure inside the cold boiler (temperature not more than 30˚C) is within the range of 1 – 2 bar.

Important: If the pressure in water mains is lower or equal to the pressure of the water inside the heating system, the heating water may run into the water mains, which is forbidden. This danger is reduced by a built-in reverse valve installed behind the top-up valve.

However, the manufacturer disclaims responsibility for any damages caused by incorrect manipulation with the top-up valve and a failure to abide by the conditions speciﬁ ed above. Such damages and defects are not covered by the boiler’s warranty.

Procedure of topping up heating water to the boiler:

• make sure that the boiler is connected to power supply and the main switch is in the ON position

• if the boiler display indicates that the heating water pressure is below 0.6 bar, information with the current pressure value appears on the display, and the red LED by the symbol (Fig. 1, position 4) ﬂ ashes on the boiler control panel

• turn-open the top-up valve (Fig. 3). Observe the pressure increase on the control panel display

• ﬁ ll the system with water, pressure should be within the range of 1.2 – 2 bar

• when the pressure has reached the required value, close the top-up valve manually.

• bleed all radiators carefully (water must

be running out smoothly and continuously, without any air bubbles);

• check whether the pressure shown on the display is within 1.2 and 2 bar. If necessary, top up the system more.

Cleaning

The boiler cover can be cleaned with a moist cloth and afterwards dried and polished with a dry cloth. Do not use abrasive detergents or solvents.

Important: Before cleaning turn the boiler off with the main switch.

Regular service

To assure continuous and safe running of your boiler, we recommend that the boiler is checked and serviced in regular yearly intervals. These inspections are not covered by the boiler’s warranty. The works to be done are speciﬁ ed in the Service Book and must be performed by an authorised service.

circumstances be acidic, i.e. its pH factor must be greater than 7 and must have a minimal carbonate hardness).

The requirements for utility water properties are deﬁ ned in STN 83 0616 (for drinking water STN 75 7111). If the water has a combined calcium and magnesium concentration greater than 1.8 mmol/l, it is useful to implement other “non-chemical” measures against incrustation (e.g. use of magnetic water treatment combined with a desludging device).

In the case of clogging of the system with dirt from the heating system or incrustation sediments or problems caused by other clogging (e.g. clogging of the heat exchanger, pump defects), such defects are not covered by the boiler’s warranty.

The distance from ﬂ ammable materials (e.g. PVC, chipboard, polyurethane, synthetic ﬁ bres, rubber and others) must be sufﬁ cient so that the surface temperature of these materials does not exceed 80˚C.

The PROTHERM Panther 24 KTV, 24 KOV, 24(12) KTO and 24(12) KOO boilers are compatible with common types of hot water heating systems and heating radiators.

Important:

The PROTHERM boilers must be put into operation only by authorised organisations according to the Czech Bureau of Occupational Safety and Czech Safety Inspectorate Notice No. 21/1979 (in the wording of Public Notice No. 554/1990 Coll.).

The boiler must be put into operation and warranty and post-warranty service must be performed by the manufacturer’s contracted service organisation, which meets the above speciﬁ ed requirements.

The boiler is designed to work in a normal AA5/AB5 environment according to STN 33 2000-3 and STN 33 2000-5-51 (i.e. within a temperature range of +5 to +40˚C and humidity depending on temperature up to maximum 85%).

The 24 KTV, 24 KOV, 24(12) KTO and 24(12) KOO boilers are suitable for zones 1, 2 and 3, i.e. in rooms with a bath tub or shower according to STN 33 2000-7701; they must not be installed in zone 8 (Fig 8.). Upon installation in the above conditions they must be protected against impact of electrical current in accordance with the same norm.

The boiler is suitable (in accordance with Public Notice no. 13/1977 Coll., i.e. noise level act) with placement in residential and social areas.

The boilers are designed to run with heating water compliant with STN 07 7401 (above all this water must not under any

Important:

The surface temperature of the upper parts of the boiler (particularly the side walls and the cover) may exceed the ambient temperature by up to 50°C.

A minimum manipulation (free) space maintained around the immediate vicinity of the boiler must be sufﬁ cient for a person to work on it safely with bare hands and with common hand tools (we recommend a minimum distance of 300 mm on all sides and min. 600 mm in front of the boiler).

In the 24 KTV and 24(12) KTO models, combustion gases must be always removed and fresh air supplied through dual ducting specially designed for this purpose. Practically any required dual ducting route can be constructed from standard components supplied by the manufacturer. The exhaust route must be constructed in such a way that condensed water vapour contained in the combustion gases can be removed from the ducting. This is implemented using special components which can be built into the exhaust route. Problems caused by condensate penetration are not covered by the boiler’s warranty. Because of the considerable variety of particular solutions, the dual ducting is not part of the boiler delivery and is not included in the price. Principles for route construction are described in the chapter Air supply and combustion gases removal ducting.

The type 24 KOV and 24(12) KOO 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 the requirements of ČSN 06 1610 and ČSN 73

4201. 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.

Connecting ramp

Distribution pipes

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.

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.

Heating system cleanliness

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.

Heating water circulation

Although the boiler is equipped with a bypass, we recommend designing the heating system so that the heating water ﬂ ows through at least some of the radiators constantly.

Note:

In the case of connection to a ﬂ oor heating system we recommend addition of a safety valve against overheating to the heating system.

Use of antifreeze compounds

We do not recommend the use of antifreeze compounds because of their unsuitable properties for the boiler. This concerns particularly their reduced heat transfer, large volume expansion, ageing and above all damage to heating water heat exchangers.

Important:

Any defects of the boiler caused by use of antifreeze compounds will not be covered by the boiler’s warranty.

Thermostatic radiator valves

If a room control unit is installed, at least one of the radiators in the reference room must be left without a thermostatic valve. For improved temperature comfort we recommend that all radiators in the room containing the room control unit are left without a thermostatic valve.

Preparing for boiler installation

Hot water system

Pressure inside the hot water system must be within the range of 1 to 6 bar. If the pressure exceeds 6 bar, a pressure reduction valve must be ﬁ tted on the supply

side, combined with a safety valve. In areas with very hard water we recom-

mend to implement suitable measures to reduce the water hardness.

Mounting procedure

Installing the boiler

Mounting the boiler on the wall

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 (Fig. 11):

1. Take the paper template (M) and attach it (for instance by adhesive tape) to the place of installation (W). When positioning the template, user a plumb line or a spirit level.

2. Using the marked points on the template, drill all necessary holes (mounting bar, connecting ramp).

Please note:

If a connecting ramp (R) is installed - not part of the boiler delivery – the connecting end pieces of the boiler (T) must not be used.

3. 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 (O).

4. Remove paper template (M).

5. Drill the required holes, respecting the diameters shown in the template.

6. Insert wall plugs into the holes for the mounting bar (L) and then fasten the bar properly with the screws provided.

7. Hang the boiler (K) on the mounting bar (L).

8. Install the combustion gases removal ducting (O) onto the boiler. Fill-in the gaps between the ducting and the wall opening with a non-ﬂ ammable material.

9. Remove the plastic plugs from the boiler outlets.

10. Install the sealing ring, ﬂ ow limiter and protective ﬁ lter on the boiler hot water inlet (S).

11. Install the connecting end pieces of the boiler (T).

Note:

If connection ramp (R) is not at-

tached.

12. Install the protective ﬁ lter to the heating water inlet (not part of delivery).

13. Mount isolation valves on all outlets from the boiler (not part of delivery).

14. Connect heating water, hot water and gas distribution pipes to the isolation valves.

15. Install lever for topping up water (P) into the heating system.

16. Run boiler (see page 10).

17. Perform check of tightness of all connections.

Mounting boiler with connecting ramp

1. If a connection ramp is used, proceed according to points 1 – 6 of the preceding chapter “mounting the boiler on the wall”.

2. Assemble connecting ramp (R) according to instructions stated on the ramp packaging.

3. Attach connecting ramp (R) to wall using fasteners and screws.

4. Install protective ﬁ lter (not part of delivery) to end of heating water inlet.

Note:

For reasons of easier maintenance install a further isolation valve behind the protective ﬁ lter of the heating water (not part of delivery)

5. Attach heating water, hot water and gas distribution pipes.

6. Remove plastic plugs and securing clips from all isolation valves and remove supporting frame of connecting ramp (R).

7. Install sealing ring, ﬂ ow limiter and protective ﬁ lter (S) on hot water inlet to boiler.

8. Mount boiler (K) on wall and attach it to isolation valve.

9. Install combustion gas removal ducting (O). Fill-in the gaps between the ducting and the wall opening with a non-ﬂ ammable material.

10. Install lever for topping up water (P) into the heating system.

11. Run boiler (see page 10).

12. Perform check of tightness of all connections.

Connecting the boiler to heating water, hot water and gas distribution pipes

The boiler pipe connection pieces must not be subjected to any forces from the heating water, hot water or gas piping system. This requires precise positioning of all connection pipes, both vertically (height) as well as the distance from the wall and mutual distances between inlets and outlets.

We recommend designing the heating system in such a way that when performing repairs, it will be possibly to drain the boiler only.

After reconstructions, in unfavourable building dispositions etc., it is possible to connect the boiler to the heating system, the hot water system as well as the gas mains by means of ﬂ exible hoses, but only those designed for this purpose. Flexible components should be as short as possible, must be protected against mechanical and chemical loads and damage, and must be replaced with new ones before the end of their useful life or before their reliability to meet their nominal parameters (as stated by their manufacturers) is diminished.

Note:

The manufacturer recommends attachment of an external utility water ﬁ lter to the boiler inlet.

Heating system operating pressure

The heating system (measured on the boiler) must be ﬁ lled up to a minimum hydraulic pressure of 1 bar (corresponds to hydrostatic water column of 10 m). We recommend to maintain the pressure within the range 1.2 and 2 bar. The boiler’s expansion vessel is sufﬁ cient for a heating system with not more than 110 litres of heating water (at temperature 75°C).

Expansion vessel

Before ﬁ lling up the heating system, check pressure in the expansion vessel. The initial pressure inside the expansion vessel should be 0.2 bar higher than the assumed pressure in the heating system.

If the heating system is already ﬁ lled up, it is necessary to shut the heating water valves located underneath the boiler and, using the draining valve, relieve the boiler from pressure. Then you can check the expansion vessel pressure and if necessary increase the pressure.

The valve for increasing pressure of the expansion vessel is located on the right side (Fig. 12).

Important:

Make sure that the expansion vessel capacity is sufﬁ cient for the volume of water in the heating system (see installation design documentation).

Safety valve

At the bottom of the boiler among the hydraulic group is on the right side located a safety valve (Fig. 13). When the maximum pressure in the system is exceeded, water or steam can be discharged from

Increasing pressure of exp. vessel

Fig. 12

the safety valve, therefore we recommend attachment of a hose to the safety valve, discharging the water into the building’s water waste system.

Important:

Under no circumstances may anyone manipulate with the safety valve while the boiler is in operation. It is also prohibited to use the safety valve for discharging water from the boiler or heating system. A safety valve clogged up with impurities from the heating system is not covered by the warranty.

Connecting gas supply

The Panther version of the boiler is designed to be fuelled by natural gas with a nominal pressure in the gas mains of 2 kPa, for which the caloriﬁ c value is most commonly stated as being between 9 and 10 kWh/cu.m. The indoor gas distribution pipes and the gas meter must be of adequate size, taking into account also the user’s other gas appliances.

All gas distribution pipes must be installed in accordance with STN EN 1775.

Important:

We recommend sealing the boiler’s gas connection point by tightening the screw cap on the head of the nozzle over the corresponding sealing (see boiler delivery).

After completing the gas supply connection to the boiler, the air-tightness of the implemented coupling must be thoroughly checked.

Topping up boiler with water

Topping up water in the boiler is described in the part “Operating instructions – Service/Maintenance”.

Draining water from the boiler

The draining valve’s main function is to relieve water pressure in the boiler during repairs. Water from the boiler can be drained using this valve only partially.

Complete draining of water either from the boiler only or from the whole heating sys-

Fig. 13

Poistný ventil

Vypúšťací ventil

Fig. 14

tem and reﬁ lling it again must be done through a ﬁ ll-up (discharge) point situated in a suitable location in the heating system.

Draining and ﬁ lling up the heating system water and the subsequent operations (bleeding, adjusting expansion vessel) are not covered by the boiler’s warranty.

If there is a danger that the hot water system water inside the boiler or the distribution pipes may freeze, measures must be implemented to prevent this from happening.

Note: The draining valve is located on the right side of the boiler by the pump (Fig.

14).

Fig. 16

In the KTV and KTO models, combustion gases must be removed and air supplied only through a dual ducting specially designed for this purpose.

Horizontal ducting sections must have a gradient allowing condensate to be discharged to the outside space or to the condensate removal ﬁ ttings. An option to slightly bend the joint of straight section and elbow is used to create small deviation from square position. Vertical sections must be always ﬁ tted with condensate removal ﬁ ttings. These must be whenever possible installed in the immediate vicinity of the boiler’s combustion gases discharge outlet. Defects caused by condensate penetrations are not covered by the boiler’s warranty.

Air supply/combustion gases removal methods (according to EN 483) and permitted ducting route lengths

Unless stated otherwise for the individual following dual ducting route design methods and their termination outlets, the ducting route lengths (from the boiler connection point to the termination outlet) may be as follows – see Table 1.

Please note:

1 Em is considered to be either 1m of straight section or one 90˚ elbow.

Important:

When the lengths speciﬁ ed in Table 1 are exceeded, it is necessary to remove the combustion gases diffuser (aperture) from the fan outlet (Fig. 16).

The following methods of air supply and combustion gases removal are permitted for this boiler:

Method C12 – vhorizontal routes with

horizontal termination outlets discharging combustion gases to free space.

When using separate ducting (80 mm) in horizontal routes with horizontal termination outlets, the air supply inlet and the combustion gases outlet from the same boiler must both be situated inside a square with a side length of 0.5m.

An example of a dual horizontal ducting route – method C

(according to STN EN

483) is illustrated by Fig. 16.

Method C

– vertical routes with vertical termination outlets into free space. For termination outlet of separate ducting, the same applies as for method C12. An example of a dual vertical ducting route – method C32 (according to STN EN 483) is illustrated by Fig. 17.

Method C

– connection to common dual chimneys. Dual ducting from each boiler (individual routes) may be terminated in common chimneys; the chimney’s trans-

Fig. 15

Air supply and combustion gases removal system for KTV and KTO boilers

Combustion gases diffuser

Method C

portation sufﬁ ciency is assessed from the data stated by the manufacturer of the used chimney ﬂ ue. If the routes are terminated in the chimney in two mutually perpendicular directions, the minimum vertical distance between them must be

0.45 m. If the routes are terminated in the chimney from opposite directions, the minimum vertical distance between them must be 0.60 m. Outlets of routes terminated in a common dual chimney are never ﬁ tted with end pieces (used in routes discharging to free space)! Both route sections (the outside – air, and the inside – combustion gases) must safely protrude into the chimney lumen, but not so deep as to form an obstacle to the ﬂ owing combustion gases or air.

In this case the concentric ducting route must not exceed the length (elbow 90° +) of 3 Em, the separate ducting route must not exceed (elbow 90° +) 9 Em (as a sum of length of the air part and the combustion gases part in total).

Method C

– dual ducting separated and

terminated at two different points (with different parameters, mainly pressures).

Separate ducting can also be used to remove combustion gases and supply combustion air (see Fig. 19). The separate ducting routes must not be terminated at mutually opposite building walls.

Method C

– connection to separately

approved and supplied piping.

Method C

– ducting used in cases where the air part is terminated in free space and the combustion gases part in a common chimney.

Air may also be taken from free space (or space with plentiful air supply) and combustion gases discharged into a common chimney (or again into a space with common presence of combustion gases). Into this method falls also the special case detailed in the second paragraph of section Method B

– see

the text below.

Fig. 24 – Dual outlet with vertical arrangement on ﬂ at outside wall Important notice!

The above cases of placing flue ducts may be used only in repairs or reconstructions of buildings.

In other cases it is necessary to proceed according to Government Regulation no. 410/2003 of the Ministry of Environment of the Slovak Republic no. 706/2002 Coll., on sources of pollution, emission limits, technical requirements and general conditions of operation, on recording of pollutant substances, categorisation of sources of pollution and the requirements for ensuring diffusion of emissions of pollutant substances.

Safety measures

The distance between any ﬂ ammable material and the combustion gases part of a separate ducting system must be such that the surface temperature of this material does not exceed 80˚C.

Combustion gases outlets must not be located in:

• places with the danger of explosion (as deﬁ ned by STN 33 1220)

Fig. 24

• building interiors (attics, corridors, staircases, etc.)

• places which can be closed, e.g. in gateway passages, etc.)

• underground structures (even when they constitute no obstacle and are open), such as tunnels, subways, etc.

It is always necessary to assess also position of a separate outlet (suction) of the air supply as appropriate with regard to these principles of prohibition of placement of combustion gases outlets.

The opening through the wall for dual ducting for air supply and ﬂ ue removal shall be made with adequate clearance (approx. 120 to 150 mm) and sealed upon completion of installation. Only incombustible material may be used for sealing (with ﬂ ammability grade A according to ČSN 73

0823) as e.g. plaster, gypsum etc. Penetrations through ﬂ ammable wall or ceiling must be made in accordance with the ﬁ rst paragraph of this section.

The boiler is connected to power supply by a three-core ﬂ exible cord with a plug. A ﬁ xed socket through which the boiler is connected to power mains must comply with the provisions of STN 33 2000-4-46. This must always have a protective (earth) contact (pin), reliably connected by a PE or PEN wire (yellow-and-green). The boiler must be always connected to the protection wire (earth) through its power cord and must be always installed in such a manner that the socket and plug are accessible. Use of adapters, extension cords etc., is not permitted.

Important:

Preparation of the plug, socket and connection of the room control unit, which requires intervention with the boiler’s internal wiring, must be always connected by a qualiﬁ ed electrician in accordance with Public Notice No. 50/1978. Likewise servicing of the electro-technical part must be performed by only a person with the above qualiﬁ cation. Before performing any works on the electro-technical part, the boiler must be disconnected from the power supply by removing the power cord plug from the power socket!

The main part of the boiler is secured by a tube fuse (T2A / 250 V), which is located on the control panel of the boiler – see diagram on pages 38 - 41.

For control of the boiler using a room control room unit only a zero-potential output room control unit may be used, i.e. a unit which conveys no foreign voltage to the boiler.

The load capacity of the regulator with relay switching is 24 V/0.1 A.

The room control unit must be connected to the boiler by a two-core cable. The

recommended copper wire cross-section for connection of a room control unit is 1.5 sq.mm.

The room control unit connection cables must not run concurrently with power wires or cables.

The terminal for connection of a room control unit with relay switching is equipped from the factory with a jumper and is located in the electrical box of the boiler control panel.

Room control units supporting “eBUS” communication may be attached to Panther boilers. For this type of control we recommend installation of only Protherm Thermolink B or Thermolink P control units. Only with these control units can the manufacturer guarantee the optimum functioning of the boiler.

The room control unit conductors are attached to the boiler terminal (Fig. 25 and

26). Using the above-mentioned room control

units it is possible to activate the function of equithermal regulation. All the equithermal curve settings are performed with the help of the room control unit.

Note:

To activate equithermal regulation it is necessary to install an outside temperature sensor. The conductors of the outside sensor are attached to the boiler terminal (Fig. 25 and 26).

The sensor is placed on the coldest wall of the building (most often the northern wall).

Important:

The conductors of the room regulator and outside sensor must not be wired concurrently with power conductors (wiring of 230 V AC).

Connection of boiler with hot water tank

The boiler can work with external types of PROTHERM tanks (B 60 Z, B 100 MS, B 200 Z etc.). For optimal use of the boiler and tank conﬁ guration you must use the NTC sensor for connection. Sensor is delivered with the boiler.

Installation of a system (boiler + tank) always requires construction preparedness. This concerns particularly all measurements (heating water, hot water, gas).

Installation of a system may be performed only by a professionally trained service worker.

The Panther 24 KTV, 24 KOV, 24(12) KTO and 24(12) KOO boilers are in their basic versions designed to use natural gas as fuel. If it is necessary to use propane gas instead, the gas jets must be replaced and the boiler parameters set as speciﬁ ed. The modiﬁ cations required to switch to a different fuel must be carried out by an authorised technician with a valid manufacturer’s certiﬁ cate.

Converting to different fuel

The gas valve designated for conversion to propane is part of the conversion kit for switching from natural gas to propane gas. The kit contains all necessary parts and instructions on how to perform the conversion.

The technical instructions for converting to a different fuel form a separate part of the Service Manual.
