The water heater is supplied by regulation and safety automatics.
Automatics of regulation maintains temperature some water in the set limits. For
this purpose there is a special temperature regulator which stops or renews gas
giving to the basic torch at a deviation of water temperature from the set sizes.
At water rise in temperature in a tank above the established size the brass tube
of a sensitive element of a temperature regulator will be extended and will delay
connected with it core. Temperature regulator levers will move a spring in повое position and will
release the regulator valve. The valve under the influence of the spring will
be closed and will stop gas access to the basic torch. Kindle will continue to
burn thus as to it gas arrives through the electromagnetic valve located before
a temperature regulator.
 As a result
of selection of hot water (on heating or for household needs) there will be a
water cooling in a tank below the established size. Thus the tube of a sensitive
element will be truncated will press a core on the temperature regulator lever.
Regulator levers will be displaced in a starting position and will open the valve.
Gas through the electromagnetic valve and the temperature regulator valve will
go to the basic torch, and it will be lighted from Kindleа.
Automatics of safety of a water heater consists of the electromagnetic valve
and the thermocouple connected to it by wires. At normal work of the device Kindle
heats up thermocouples, the electromotive power develops in chains and in knot
of the electromagnetic valve the magnetic field keeping the valve in opened position
is formed. Thus gas arrives to the basic torch. In a case kindleа thermocouples
the electromagnetic valve will cool down also will close gas access to the basic
torch and Kindleу. Repeated ignition Kindleа is necessary for making manually,
but not earlier than in 2 minutes.
