the water heater on occurs at water consumption not less than 2,5 l/min, at the knob position at
“Maximum consump-
tion
”
– at water consumption not less than 6 l/min. In the in-between positions of the knob 1 switching the water heater
on occurs, respectively, in the consumption range not less than 2,5...6 l/min.
At reduced inlet water pressure (at small water consumption provided by the water supply pipeline) for switching the
appliance on it is recommended to leave the appliance’s knob 1 in the position
“Minimal consumption”
. In this position it
is possible to receive small and middle hot water consumption (2,5...5 l/min) by the outlet from the appliance. In order to
receive big amount of warm water by the appliance
’s outlet at normal inlet water pressure (if consumption of 6 l/min and
more is provided by the water supply pipeline) the knob 1 should be switched to the position
“Maximum consumption”
.

«BaltGaz NEVA-4511»’s regulation knobs’ position
Note 1.
At small consumption of water going through the appliance that is in operation, turning the knob 1 to the posi-
tion
“Maximum consumption”
may
lead to the burner’s flame failure. The burner’s flame failure is possible also in case
of reducing the consumption by the hot water tap or at reduction of the inlet water pressure. In order to put the burner into
operation again, it is necessary to turn the knob 1 to the position
“Minimal Consumption”
or to increase water consump-
tion by the hot water tap.
3.3.2. Water temperature regulation through the appliance at its fixed consumption rate is effectuated by turning the
gas consumption regulation knob 2 (scheme13,14): turning the knob into the position
“Maximum consumption” increases
gas consumption and water
temperature at the appliance’s outlet, turning the knob to the position “Minimal consumption”
reduces gas consumption and water temperature at the a
ppliance’s outlet.
It is also possible to regulate water temperature by the appliance
’s outlet by changing water consumption with hot
water tap or knob 1:
water consumption increase leads to its temperature’s reduction, and on the contrary water con-
sumption reduction leads to its temperature increase.
Note 2.
Water heating temperature is limited by the appliance
’s heating effect: at big water consumption, especially
in winter time, water at the appliance
’s outlet may have unsufficient temperature even at maximum gas consumption. In
this case in order to increase water temperature it is necessary to reduce the consumption of the water going through the
water heater.
Water temperature at the appliance
’s outlet is shown on the two-digit digital display installed on the decorative trim
on the appliance’s casing.
Note 3.
At small water consumption (with knob 1 in the position
“Minimal consumption”
) and big gas consumption
(with knob 2 in the position
“Maximum consumption”
) water overheating in the heat exchanger is possible and conse-
quently the burner might be switched off by the authomatic control system of the appliance. In order to switch the appli-
ance on once again it is necessary to close the hot water tap and then to open it once again. In order not to let the water
overheating occur it is necessary to reduce gas consumption with the knob 2 or to increase consumption of water going
through the appliance with knob 1 or hot water tap.
Water overheating in the heat exchanger leads to appearance of noise during the appliance
’s operation and causes
quick appearance of scale deposit in the pipes of the heat exchanger and narrowing of their clear opening what eventual-
ly
leads to the appliance’s operation efficiency reduction and diminution of hot water current. So in order to reduce the
temperature of water coming out of the appliance it is not recommended, especially in case of hard water, to use the mix-
er tap adding cold water, but it is recommended to use the above-listed methods.In order to reduce scale deposit appear-
ance intensity
it is recommended to prevent water heating at the appliance’s outlet for more than
60
С.
3.4. Switching the appliance off
After finishing the appliance
’s usage (at nighttime, when not being at home etc.) it must be switched off. In order to
switch the appliance off it is enough to stop water flowing through it by closing all hot water taps, after this it is necessary
to make sure that the flame of the burner has completely gone out.
ATTENTION
!
In case if after closing all hot water taps the main burner continues operating it is necessary
to:
Immediately shut the gas supply off with the gas stop valve installed by the inlet into the ap-
pliance.
Then it is necessary to call the specialized service
organization for the appliance’s repair.
