Possible failures of
«BaltGaz NEVA-4511»
Failure
Probable cause
Methods of elimination
When the hot water tap is
opened the appliance does not
switch, there is no electric spark.
The batteries are not installed into the battery
secton (or they are improperly installed) or
they are fully discharged.
Install or replace the batteries in ac-
cordance with polarity.
Unsufficient water consumption for switching
the appliance on at the set position of the
knob 1 (scheme2).
Increase water consumption with hot wa-
ter tap or move the knob
1 to the position
“Minimal consumption”
(scheme 5).
Unsufficient water consumption because of
incomplete opening of the taps.
Open the stop valve by the
appliance’s
inlet and the hot water tap completely.
Unsufficient water consumption
(less than 2,5 l/min while the taps are opened
completely), caused by the following:
Low water flow rate in the DHW pipeline
Violation of the requirements stated in this
manual at pipelines installation
.
Water filter stoppage.
Scale deposit in the heat exchanger.
Address the sanitary engineering service
in order to eliminate the cause of low
water flow rate.
To effect installation of the pipelines in
accordance with the requirements of this
manual.*
To clean or replace water filters.*
To slean the heat exchanger from scale
deposit (see p. 12.3.2).*
Electrical open.
Find and eliminate the electrical open.*
Appearance of soot deposit on the ignition plug
electrode.
Effect the ignition plug electrode
’s clean-
ing from soot deposit *.
The electronic control block, the miscro
switch or the water block membrane is out of
service.
Replace the broken items.*
The appliance does not switch
on when the hot water tap is
opened, there is an electric
spark.
The gas stop valve by the inlet into the appli-
ance is closed.
Open the gas stop valve by the inlet into
the appliance.
Presence of air in gas pipelines
.
See note p. 3.2.
The electromagnetic valve is out of service or
the contacts of its connection are disrupted.
Replace the electromagnetic valve or
restore the contacts. *
The electric spark does not get into the cur-
rent of air and gas mixture of the burner.
Regulate the distance
5±0,5 mm be-
tween the ignition plug electrode’s end
and the burner’s nozzle.*
The supply of liquefied gas in the balloon has
expired.
Replace the balloon with liquefied gas
.
Слабый искровой разряд.
The batteries have discharged.
Replace the batteries
.
The contacts of the battery section are oxy-
genized.
Clean the contacts of the battery section
.*
After
После short-term opera-
tion the appliance is switched
off.
Unsufficient draught (the appliance is
switched off by the authomatic control sys-
tem).
Effect the smoke exhauster cleaning.
Make the gas flue pipe joints airtight.*
The hot water temperature at the
Appliance
’s outlet is more than 90 °С (the
appliance is switched off by the authomatic
control system).
Close the hot water tap and when
switching the appliance on the next time
( in 1-2 minutes) reduce the hot water
temperature, reducing gas consumption
or increasing water consumption
.
The water block membrane is damaged
Replace the water block membrane.*
The contact with the flame sensor is disrupt-
ed or the sensor
’s electrode touches the
burner’s details or is out of the flame zone
(the burner operates during 7 seconds at
continuing electric sparks and then switches
off).
Restore the contact with the flame sen-
sor, regulate the position of its elec-
trode.*
Appearance of soot deposit on the flame sen-
sor
’s electrode.
Effect the cleaning of the flame sensor
’s
electrode from soot deposit *.
There are no temperature read-
ings on the water temperature
display.
The water temperature display is not con-
nected (the contacts are disrupted).
Connect the water temperature display
(restore the contacts).*
The water temperature display is out of ser-
vice.
Effect the water temperature
display’s
replacement.*
After switching the appliance on The water temperature sensor is not con-
Connect the water temperature sensor
