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.

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.
