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..
