3. USAGE OF THE APPLIANCE
For normal and safe appliance operation the conditions presented in p. 2.2.9, 2.2.15 and 2.2.18 (see
Table 1, page 4) must be fulfilled. Non- compliance with these conditions can cause the appliance’s
inappropriate or unstable operation and even its breakdown. The heating effect of the appliance
indicated in the p. 2.2.2 is provided (with an accuracy ±5%) at rated gas pressure on the inlet into the
operating appliance, indicated in the Acceptance certificate.
3.1. Putting the appliance into operation
3.1.1. In order to put the appliance into operation in a general case it is necessary to:
a) Install the power element into the battery section (see p.3.4, page 8);
b) Open the stop valve of cold water by the inlet into the appliance;
c) Open the stop valve on the gas pipeline by the inlet into the appliance
d) Open the hot water tap, while spark discharges should appear between the plug and ignition burner (if
the water flow going through the appliance will be at least 2.5 l/min), from the spark discharges the
ignition burner should ignite and from the ignition burner the main burner should ignite. After igniting
the main burner the ignition burner’s flame must go out.
ATTENTION! To avoid burns, do not approach your eyes too close to the viewing window while the
appliance is being switched on.
Note: At first launching of the appliance or after long-term period of break in appliance’s operation, the
ignition burner’s ignition will occur only after air removal out of gas pipeline. As the spark discharges last
not more than 60 seconds after switching the water on, for continuing the ignition it s necessary to close the
hot water tap, and then open it again. You need to repeat this procedure until complete air removal out of the
pipeline and until the ignition burner ignites.
3.1.2. Changing of water consumption with which switching the appliance on and off occurs is effectuated
by the knob of the tap 15 (scheme. 14, 15, 16). Turning the knob 15 clockwise (counterclockwise)
leads also to reduction (increase) of consumption of water running through the water heater.
Switching the appliance on at leftmost position of the knob of the tap 15 (minimal water consumption –
see scheme 14, 15, 16) occurs at water consumption 2,5 l/min, switching off - at 2 l/min. Such knob position
is recommended at low inlet water pressure (with small consumption of water provided by the water supply
network).
Switching the appliance on at rightmost position of the knob of the tap 15 (maximal water
consumption) occurs at water consumption 3 l/min, switching off-at 2,5 l/min. With such knob position it is
possible to receive increased consumption of heated water by the appliance’s outlet..
3.2. Water temperature regulation
3.2.1 Water temperature regulation at the appliance’s operation.
Page 10
12
3.2.2. The temperature of hot water running out of the appliance is shown on the digital display 8 (see
scheme 1). Also on display, when pressing the buttons 9 or 10 the hot water temperature set by the
user is shown. Pressing the button 9 reduces the set temperature, pressing the button 10 increases it.
The hot water temperature can be set in the range from 35 °С to 70 °С: in the range from 35...50 °С
with a step of 1 °С, and in the range from 50…70 °С – with a step of 5 °С. In 2-3 seconds after you
stop pressing the control buttons the real temperature of hot water by the appliance’s outlet is shown
on display.
When water flow through the appliance is changed (by the water tap or due to change of pressure in the
water supply pipeline) and when gas pressure in the network or inlet water temperature is changed, the
control system automatically changes gas consumption, keeping the water temperature set by the user.
Note.. The possibility of keeping the set hot water temperature is limited by the appliance’s heating
effect (18 kW), i.e. in case of low inlet water temperature (in winter time), or in case of high set water
temperature and substantial increase of its consumption the hot water temperature by the appliance’s outlet
can be reduced to a value lower than the set one (error code Н1). So in order to keep the set hot water
temperature more stably it is recommended to set water temperature not more than 45 ...50 °С and limit the
water flow through the appliance, turning the knob 15 (scheme.) clockwise up to the stop (into the leftmost
position).
After switching the appliance on, setting new temperature or changing the water flow through the
appliance, the set water temperature will not be reached immediately, but only in some time, necessary for
automatic adjustment of the main burner’s power. At that, a short-term increase of water temperature by the
appliance’s outlet higher than the set one is possible..
When water consumption is reduced to 2...2,5 l/min and less automatic switching off of the appliance
will occur. In case of water consumption not much higher than the switching off threshold the appliance’s
operation may be unstable (error code L0).
The control system remembers the last set temperature value and at the appliance’s next launching it
will heat water to this temperature. The appliance’s memory is energy-dependent: when switching a new
appliance on or after the power elements replacement the system sets water heating temperature 45 °С by
default.
Note 1. Water overheating in the heat exchanger causes the appearance of noise during the appliance’s
operation and causes fast scale deposit appearance in the heat exchanger’s pipes and narrowing of their flow
sections, what in some time will lead to the appliance’s operation efficiency reduction and weakening of hot
water jet. So in order to reduce the appliance’s output water temperature it is not recommended to use a
mixing vessel, adding cold water but to use the above listed methods.
Note 2. It is not recommended to set high hot water temperature by the appliance’s outlet if not
necessary, as water overheating in the heat exchanger causes the appearance of noise during the appliance’s
operation and causes fast scale deposit appearance in the heat exchanger’s pipes and narrowing of their flow
sections, what in some time will lead to the appliance’s operation efficiency reduction and weakening of hot
water jet. So in order to reduce the appliance’s output water temperature it is not recommended to use a
mixing vessel, adding cold water but to set the temperature needed in the water pumping point by means of
control buttons.
3.3. Switching the appliance off
3.3.1 In order to switch the appliance off it is enough to stop water flow through it, closing all hot water
taps. After closing all hot water taps it is necessary to make sure that the main burner’s flame has
completely gone out.
ATTENTION! If after closing all hot water taps the main burner is still operating, it is necessary
to immediately block gas supply by means of the gas stop valve of the appliance’s inlet, and call a
specialized service organization for the appliance’s repair.
Page 11
13
3.3.2 When you finish using the appliance (at night time, not being at home etc.) it is necessary to switch
it off, following the following sequence:
a) Close the hot water taps;
b) Close the stop gas valve by the appliance’s inlet;
c) Close the cold water stop valve by the appliance’s inlet
In case of hard water, in order to reduce scale deposit appearance it is recommended to reduce water
consumption by the hot water tap before closing it until the main burner switches off (less than 2
l/min) and let the water run through the appliance until it is warm. Then close the hot water tap.
3.4. Replacing the appliance’s power elements
3.4.2. The indicator of the power element’s discharge is the flickering of the indicator 11 (see Scheme 1)
3.4.3. The new power element of typical size D is installed into the battery section 13 (see scheme. 10,
scheme11, scheme. 12).
When installing the power element it is necessary to observe polarity in accordance with the scheme on
the inner side of the section’s cover.
It is recommended to install alkaline power element type LR20 with high energy output ratio that
ensures more durable operation of the appliance. Installation of low-quality power elements or elements with
low energy output ratio may lead to their quick discharge and the appliance’s loss of function.
3.5. Protection from freezing
If after switching the appliance off water freezing in it is possible, it is necessary to drain the water out
of it as follows:
a) Close the gas stop valve and cold water tap by the appliance’s inlet;
b) Open the hot water tap and turn the knob of the tap 15 (scheme 10, scheme 11, scheme 12) to the
rightmost position;
c) Unscrew the gag 14 and let the water leak into a tank;
d) Screw the gag 14 back up to the stop and close the hot water tap.
3.6. Actions in emergency situations
In case of emergency situation during the appliance’s operation it is necessary to:
a) Close the gas stop valve by the appliance’s inlet;
b) Close the cold water stop valve by the appliance’s inlet (in case of water leakage);
c) Call a specialized service organization for the appliance’s repair.
ATTENTION! In case of failures in the combustion products removal system gas supply to the
burner stops. In case of the appliance’s switching off by a signal from the thermo relay (draught sensor
16, Scheme 10, Scheme 11, Scheme 12) it is necessary to close the hot water tap and ventilate the
premise.
Restarting of the appliance will be possible after the thermo relay cools down (in 1-2 minutes). In
case of the appliance’s repeated switching off by the draught sensor it is necessary to address to the
specialized service organization for gas removal system failure elimination. Disconnecting the draught
sensor or its incompetent handling is unacceptable and may lead to sweetdamp poisoning.
4. appliance treatment
In order to ensure long-term and failure-free operation of the appliance and keep its operating
characteristics it is necessary to regularly effectuate its examination, treatment and technical service.
Page 12
14
In order to ensure fire safety it is necessary to carefully and attentively look after the burners’ cleanliness,
not to allow smoky flame appearance at gas combustion, which leads to soot deposit appearance on the
heat exchanger. At that gaps between the heat exchanger’s fins are covered with soot and as a result the
flame casts out from the combustion chamber which can lead to fire.
The examination and treatment of the appliance are performed by its owner.
Technical service of the appliance is performed by the specialized service organization not later than 12
months from the date of installation and then not less than once per 12 months.
ATTENTION! Works connected with technical service are not the manufacturer company’s
warranty liabilities and are effectuated at the customer’s cost.
.
4.1 Examination
4.1.1. Every time before switching the appliance on it is necessary to:
a) Make sure that there are no flammable objects next to the appliance;
b) Make sure that there is no smell of gas in the premise, in case if the smell of gas is detected, address to
the gas facilities service.
4.1.2. At the ignition burner’s ignition it is necessary to check its operability by the combustion behavior:
the ignition burner’s flame must not be smoky and must reach the flame sensor’s electrode and the main
burner.
4.1.3 After the main burner’s ignition it is necessary to visually check its operation: the flame should be
blue and straight without any yellow smoky edges indicating the contamination of the inner channels of the
burner’s blades.
The burner blade’s inner channels contamination causes incomplete gas combustion and it leads to the
appearance of big amounts of the following:
- carbon monoxide, which can cause poising;
- soot that forms deposit on the heat exchanger what worsens heat exchange and can cause the
appliance’s breakdown
4.2 Treatment
4.2.1. The appliance should be kept clean, for this it is necessary to regularly remove dust from the upper
surface of the appliance, and also to wipe the casing at first with a wet rag, then with a dry one. In case of
substantial contamination, it is necessary to wipe the casing at first with a wet rag moistened in a neutral
detergent, then with a dry rag.
4.2.2. It is forbidden to use detergents of heightened effect and containing abrasive particles, gasoline or
any other organic solvents to clean the surface of the casing and plastic parts.
ATTENTION! It is allowed to perform all appliance treatment operations only after the appliance
is switched off and cooled down.
5. RULES OF TRANSPORTATION AND STORAGE

recommended to install the alkaline power elements of the LR20 type, with higher energy output ratio
providing more durable operation of the appliance.
7.9 Checking the appliance
After installing the appliance and checking it on air-tightness, you must check: the operation of the
ignition and main burner (p. 4.1.2, 4.1.3, page 9), automatic safety devices operation (п. 8.2.6, page 20), and
the hot water’s temperature and consumption. Switching the appliance on and off and regulation of its water
temperature must be effectuated in accordance with section 3 (page 7).
Note: After keeping the appliance in a premise with sub-zero temperature, it is recommended to perform
its first launching not earlier than in 1,5 h after it was brought to a warm premise.
If necessary (in case of insufficient water heating) the appliance’s inlet gas pressure should be checked.
In order to measure gas pressure, having previously closed the gas stop valve by the appliance’s inlet, it is
necessary to connect a manometer to the fitting 17 (Scheme 10, Scheme 11);
Gas pressure measurement must be effectuated on the operating appliance and at maximum gas
consumption. Gas pressure must comply with the value indicated in the Acceptance certificate.
7.10Rendering the appliance to another type and pressure of gas
7.10.1 Rendering the appliance to another type of pressure or gas must be done by a specialized service
organization. For rendering it is necessary to use only a branded set of details.
Before rendering it is necessary to switch the appliance off and close the gas stop valve.

Scheme 13. Flow chart of the appliance «BaltGaz NEVALUX-6011»
8.2.2 At the beginning of water flow through the water block 32 with water consumption not less than 2,5…3
l/min the gas valve 23 is opened by the membrane stem 18 and the contacts of the micro switch 21 close. After
this the valve 27 opens gas supply from the cavity behind the membrane of the valve block 25 to the ignition
burner 3 and from the control block 11 high-voltage current impulses are supplied to the plug 9.From the
electric sparks between the plug’s electrode and the ignition burner’s nozzle the ignition of the ignition burner
occurs. After the ignition burner’s ignition, what can be defined by the flame sensor 8, the valve 26 closes gas
supply to the cavity behind the membrane of the valve block, gas from the cavity behind the membrane comes
out through the ignition burner and the membrane 28 of the valve block opens the valve 29 supplying gas to
the main burner 10 with the help of pressure drop. The main burner ignites and the ignition burner’s flame
goes out. The main burner’s operation is controlled by the flame sensor 8.
8.2.3 Then the electronic control block 11 compares the given water temperature value with the value
measured by the sensor 4.If the temperature difference exceeds 1oC, the electronic control block, controlling
the valves 26 and 27, corrects the position of the valve 29 changing this way the amount of gas supplied to the
main burner. Opening the valve 26 if the valve 27 is closed increases gas pressure in the cavity behind the
membrane 28, at that gas consumption reduces and the appliance’s power decreases. Opening the valve 27
when the valve 26 is closed reduces the pressure in the cavity behind the membrane 28, at that gas
consumption increases and the appliance’s power grows.
8.2.4 The tap 15 changes water consumption in a small range and the displacement of the membrane 18:
turning the tap clockwise reduces water consumption and increases the membrane’s displacement, turning the
tap counterclockwise increases water consumption and reduces the membrane’s displacement. So the tap 15
influences also the water consumption value, with which the appliance switches on (ignition of the ignition
burner, and then of the main burner) and switches off (switching off of the main burner). When the tap is
turned clockwise up to the stop (this position is shown on Scheme 14, 15), the water heater is switched on
with the consumption of 2,5 l/min, and switched off with the consumption of 2 l/min. When the tap is turned
counterclockwise up to the stop the water heater is switched on with the consumption of 3 l/min, and switched
off with the consumption of 2,5 l/min.
8.4.5.At water flow stop or at its consumption reduction to a volume less than 2...2,5 l/min the contacts of the
micro switch 21 open and the valves 23 and 29 close and the main burner’s flame goes out.
8.4.6. The appliance is equipped with safety devices, providing:
- Gas access to the ignition and main burners only in case if there is water flow
- Gas access to the main burner during the ignition only in case if there is a flame on the ignition
burner
water flow stop;
