1. DESCRIPTION OF FUNCTION
Indirect heating stationary heaters fro the NTR and NTRR ranges are used for preparation of hot utility water
in connection with another source of heating water, ost frequently a gas boiler. In the case of NTRR types
heating is ensured via a co bination of two sources of heating water (gas boiler + solar syste or heat pu p).
The no inal outlet ensures sufficient a ounts of hot utility water even for large flats, business pre ises,
restaurants and si ilar facilities In the event of increased consumption of hot utility water, the storage
heaters additionally heat water continuously and work in a similar manner to a flow heater.
The producer reserves the right to make technical changes to the product.
The product is intended for permanent contact with drinking water.

2. INFORMATION FOR THE CONSUMER
Consumption of hot water
Consu ption of hot water in the household is dependent on the nu ber of people, a ount of sanitary
equip ent, length, dia eter and insulation of water ain pipes in the flat or house and on the individual habits
of the users.
Energy savings
The hot utility water storage vessel is insulated with high-quality polyurethane foa with no CFCs.
Only set the te perature on the heater ther ostat to the level you really need for operation in the household. In
doing so you will decrease consu ption of electrical energy, the a ount of li e scale on the walls of the vessel
and on the exchanger.
Advantages of using an indirect heater

The shut-off valve by the exchanger ust be open and thus the flow of heating water ensured fro the
hot water heating syste .
It is reco ended that an air release valve is fitted together with the shut-off valve on the inlet to the
exchanger, which according to require ent, especially at the beginning of the heating season, can be used to
vent the exchanger (fig. 1).
The period for heating required by the exchanger is dependent on the te perature and flow rate in the
hot water heating syste . The co bined heater is produced in a universal design – fitting of a shut-off valve to
the heating insert fro the right or the left (fig. 1).
5. OPERATION
Operating controls for heaters with volu es of 50 to 160L are located under the see-through cover of the control
panel.

Setting the temperature
The water te perature is set by turning the ther ostat dial. The required sy bol is set in relation to the fixed
point on the control panel.
Warning: setting the ther ostat dial as far to the left as possible does not ean that the heating ele ent is
per anently switched off.
On operation of the heater without blocking of the daily rate, we do not reco end the te perature being set
above the level of 65°C.
Select the axi u sy bol “6 ”.
Restriction of the regulation range; blocking settings (only applies to volu es 50 to 160L).
Due to various safety reasons (unwanted scalding, prevention of anipulation by children or an unauthorised
person) the range of regulation can be restricted or blocked by setting the ther ostat.
Restriction of regulation – pull off the ther ostat dial (this will be quite difficult the first ti e),
You will find two φ2.15 cylindrical pegs on the reverse side
- Pull out one peg and insert it into the appropriate hole for the selected
axi u te perature.
- Refit the dial (as far as it will go).
Blocking settings - Set the selected te perature
Pull of the dial without changing the setting, you will find two pegs on the reverse side,
pull both of these out and insert the into the holes corresponding to the selected
te perature in such a way that there is no hole in the space between the pegs and the
position is opposite the set te perature.

Before ounting the product, the load bearing capacity of the wall ust be checked and a suitable
ounting bracket ust be chosen according to the type of wall, or if necessary, the wall ay need to be
reinforced. Water heaters fro the NTR/Z range are only to be ounted in a vertical position in such a way that
the botto edge of the heater is positioned at least 600 above the floor (figs. 4 and 5). Only install water
heaters fro the MORA-TOPV NTR range in a horizontal position so that fro the front view the right edge of
the heater is positioned at least 600 fro the opposite wall (figs. 4 and 5).
In the case of co bined heaters, it is necessary before ounting onto the wall, to fit a bend to the inlet
and outlet for heating water and to deter ine ounting fro the right or fro the left by turning this (fig. 1).
With a view to the different types of supporting brickwork and wide range of special brackets available
on the arket, we do not supply the heater with this aterial. Mounting syste s ust be selected individually
subject to the conditions. We reco end mounting on the wall and to leave ounting to a specialist company
or to discuss mounting with a specialist.
7. PLUMBING INSTALLATION
Connection of heaters to plu bing fittings is illustrated in figs. 1 and 2. In the event of disconnection of
the heater, Js 3/4“ screw connections ust be fitted to the inputs and outlets for utility water. If the hot utility
water distribution ains is equipped with a circulation circuit, the “return” is connected to the inlet arked
CIRCULATION.
Types 100, 125 NTR and 100, 125, 160 NTR / HV are equipped with a discharge outlet. In the case of type 160,
200 and 250 NTR(R) a “T” fitting ust be attached to the hot utility water inlet with a discharge valve.
For operation, the heater ust be equipped with a pressure relief valve. The pressure relief valve is fitted
on the input for cold water arked with a blue circle. There ust be no stop valve fitted between the heater and
the pressure relief valve. On fitting, follow the instructions of the manufacturer of this pressure relief
equipment.
The pressure relief valve ust be checked every ti e it is set into operation. The check is perfor ed by
anually pulling away the e brane fro the valve seat. Correct functioning of the ake-and-break device is
displayed by water flowing out via the waste water spout on the pressure relief valve. During regular operation,
this check ust be carried out at least once a onth and always after the heater has been put out of operation for
longer than 5 days.
Water ay drip fro the pressure release valve via the discharge pipe, the pipe ust be freely opened to
the at osphere, positioned end to end facing downwards and ust be in an environ ent free fro te peratures
below the freezing point.
If there is greater excess pressure in the input pipe (even te porarily) than 0.6 MPa, a reduction valve
ust be fitted before the pressure release valve.
Hot utility water is taken off via the ixer tap fro the discharge pipe arked with a red circle. For
longer hot water distribution pipes, it is suitable to insulate the pipes in order to decrease heat loss. All outlets
ust be fitted with ixer taps for the option of setting the required te perature. The heater must be fitted with
a discharge valve at the input for cold utility water to the heater (fig. 1) for possible dis ounting or repair.
Installation ust correspond to valid regulations and ČSN.
For correct setting of the pressure control valve we reco end that the pressure in the valve is 2 %
lower than the opening excess pressure in the pressure relief valve. (i. e.0,48 MPa) .
We reco end the shortest possible hot water pipe fro the heater so as to ini ise heat loss.
8. CONNECTION OF THE INDIRECT HEATER TO A HOT WATER HEATING
SYSTEM (fig. Exa ples of connection… + fig. 1)
It is advisable to fit cut-off valves to the inlet and outlet for heating water (for possible disasse bly of the
heater). The valves should be as close to the heater as possible in order to preclude larger levels of heat loss.
The heating circuit is connected to the arked inlets on the heater exchanger and an air relief valve is installed
in the highest position. A filter ust be installed into the circuit for protection of the pu ps, the three-way
valve, the backflow valve and to stop the exchanger beco ing clogged. We reco end that the heating circuit
is flushed out before installation. All connection ains should be properly equipped with heat insulation.
If the syste is to be operated with priority heating of hot utility water with the aid of a three-way valve, always
proceed during installation according to the instructions of the anufacturer of the three-way valve.

After connection of the heater to the eater ains, hot water heating syste , el. network and after testing of the
pressure relief valve (according to the instructions that ca e with the valve), the heater can be set into
operation.
Procedure:
a) Check the water ains, electrical installation and in the case of co bined heaters also the installation
for the hot water heating syste . Check to the correct positioning of the sensors for the operational
ther ostats. The sensors ust be pushed all the way into the cha ber as far as they will go.
b) Open the hot water valve on the ixer tap
c) Open the valve in the inlet pipe for cold water to the heater
d) As soon as water begins to spill out of the valve for hot water, filling of the heater is co plete and the
valve should be closed
e) If any leak is apparent (the flange lid), we reco end you tighten the screws on the flange lid
f) Screw on the cover for the electrical equip ent
g) When operating heating of utility water using heat energy fro the hot water heating syste , open the
valves at the inlet and outlet for heating water and if necessary vent the exchanger
h) On setting the heater into operation, flush out the heater until the cloudiness has disappeared.
11. CLEANING THE HEATER AND REPLACEMENT OF THE ANODE BAR
Through repeated heating of water, li e scale is deposited on the walls of the vessel and above all on the lid of
the flange.
The level of deposit is dependent on the hardness of the heated water, its te perature and on the a ount of hot
water consu ed.
We recommend a check and if necessary cleaning of the lime scale from the vessel after two years of
operation as well as replacement of the anode bar if necessary. The life span of the anode is theoretically
calculated for two years of operation although this does vary depending on the hardness and che ical
co position of the water in the location where the heater is used. It is possible to deter ine the date for next
replace ent of the anode bar on the basis of this inspection. Leave cleaning and exchange of the anode to a
co pany, which perfor s service work. When releasing water fro the heater, the valve on the ixer tap for
hot water ust be open so no low air pressure is created in the heater vessel, which would restrict the water
fro escaping.
12. IMPORTANT NOTICE
-The MG anode ust be regularly checked and replaced
-There must be no stop valve fitted between the heater and the pressure relief valve.
-In the event of excess pressure in the water ains in excess of 0.6 MPa a reduction valve ust be fitted
before the pressure relief valve.
-All outlets for hot water ust be fitted with ixer taps.
-Before water is allowed into the heater for the first ti e, we reco end a check is ade on the tightness of
the nuts on the flange joints of the vessel.
-Any handling of the ther ostat apart for setting of the te perature using the control dial is forbidden.
-All work on the electrical equip ent, setting and replace ent of regulation ele ents ust be perfor ed by
a professional service business.
