Draught controller
The instructions for the draught controller setting are given in the manual attached to the particular controller.
Filling of the heat system with water:
Water for filling of the furnace and the heat system must be pure and colourless, without suspended
substances, oil and chemically aggressive substances. Its hardness must correspond to
Č
SN 07 7401 and in
case it does not correspond it is necessary the water to be adjusted. Even multiplying heating of the water
with higher hardness does not prevent from excluding of soils on the boiler drum walls. The precipitation of
1 mm of limestone reduces in the given place the heat transfer from metal to water by 10 %.
Heat systems with an open expansive tank allow direct contact of the heat water with atmosphere. In the
heat period the expansive water in the tank absorbs oxygen that increases the rust effects and at the same
time a considerable vaporization of water occurs. Only water adjusted to values according to
Č
SN 07 7401
can be used for fill – up. The heat system is needed to be rinsed so as all impurities have been washed out.
During heat period it is necessary to keep consistent water volume in the heat system. While filling – up of
the heat system with water it is necessary to prevent the air from leeching onto the system. The water from
furnace and heat system must never be impregnated or taken out for use except for cases necessarily
needed such as repairs, etc. By draining the water and filling with new one the risk of rust and scale creation
is increased.
If it is needed to fill water into the heat system we fill it only to a cooled down furnace to
prevent section cracking.
After filling of the furnace and heat system checking of tightness of all joints is
needed.
The finishing of assembly and the heat test performance must be recorded in the warranty card.
