2. Boiler Accessories
A
PROTHERM KLO
boiler consists of the following parts:
1. Cast-iron boiler body with thermal insulation and water-connection pipes;
2. Burner plate, including gas supply and ignition part;
3. Flue-gas duct, with draft dampener and SKKT thermostat;
4. Boiler casing, control panel, and terminal board;
5. Boiler body base.
Cast-iron boiler body
consists of elements and serves as a combustion chamber (including the flue-gas outlet) and water
chamber (including the water ways). There are side elements ("Left" and "right") and middle (of one type). The elements are put
together to create a body of the corresponding size (of both the combustion and water chambers). A completed body is equipped
with water pipes for connection of water, insulated to prevent heat radiation, and provided with fixtures for thermostat sensors and
on the legs, fixtures for mounting on the base.
Burner plate
is equipped with part of gas piping, burner tubes, and ignition equipment. Depending on the boiler (and body) size,
it includes between 2 to 6 burner tubes and the gas pipe, which leads to the combined gas armature. This in turn regulates gas
supply to the boiler, depending on the required and actual parameters (i.e., the state of the boiler and the heating circuit); the gas
pipe leading out of the armature is part of the burner plate, with 2 to 6 nozzles, (one per each burner tube). Gas is ignited by an
electric spark.
Flue-gas duct
contains a draft dampener and flue-gas outlet (to which the flue duct is connected). It is equipped with a removable
cleaning cover, which is accessible after the top casing panel of the boiler is removed.
The SKKT chimney-draft control system monitors flue-gas temperature in the duct. If the draft is worsened, the temperature rises,
and the thermostat inserted in the duct will switch off the boiler (shut down gas supply to the boiler).
Boiler casing
consists of covers, fixed back wall and side panels, removable front panel and removable top casing panel. The
control panel is situated at the upper part of the boiler.
Boiler body base
consists of two brackets connected to the bottom of the body, supporting the casing weight. It is also provided
with holes for bars (approx. 1/2"), which make handling of the boiler possible without a pallet, if a sufficient number of people are
available.
The base also includes reflexive sheet, which substantially reduces heating of the floor under the boiler. The reflexive sheet is
inserted from the side into the base brackets, exactly under the cast-iron body; its bent edges must be directed downwards along
the brackets.
