Mareli Systems
The boiler consists of the following elements:
•
The heat exchanger comes in a two-door kit which is used depending on the fuel type(available for
mounting the pellet burner);
•
The heat exchanger is a welded construction made of steel sheet material. In the front lower part there
is a furnace chamber and underneath the ash container is placed. The heat exchanger is compact and
constructively based on a triple-motion principle, which enables an optimal heat exchange and high
efficiency;
•
The ceramic elements mounted in the combustion chamber ensure an optimal burning process and a
complete combustion of the fuel;
•
The ash tray is situated on the bottom of the combustion chamber. There the remaining ash is gathered
and it allows for easy cleaning of the device;
•
The incoming and outgoing connector for feeding and the unloading water are situated in the rear part of
the boiler and represent two terminals with an outer thread G1½ through which the device is connected
to the heating system;
•
The drainage hole is a terminal with a G1/2 thread upon which an unloading valve is to be mounted;
•
The funnel (with an outer diameter of F145) is situated in the upper rear part of the boiler, and leads off
the smoke gasses through the chimney;
•
The steel heat exchanger is isolated with mineral isolation which reduces the environmental thermal
losses;
•
The outer decorative walls are made of steel sheet iron and are worked with a high quality colour layer;
The water heating boiler is manufactured with a two-door kit
(left and right) depending on the fuel that is to going be used.
The door with an air valve is used for solid fuel (wood, coals).
The valve is connected to the thermal regulator with a chain and
thus controls the boiler temperature. The precise adjustment of
the regulator is done on start up of the unit.
The door that is designed for the burner has an opening, in
which it is mounted with M6 screws. After the burner is mount-
ed, a steady tightening of the screws must be done so the isola-
tion between the burner’s flange and the boiler’s door is secured.
Basic information about the operation of the boiler:
•
The thermal output on which the burner is set;
•
The degree of impurity of the boiler’s heating surfaces;
•
The degree of insulation on the door and the lids of the
boiler’s combustion chamber (the condition of the insu-
lating ropes)
•
The power chimney draft;
