Operators And Supervisors; Use; Technical Description Of The Boiler - Opop ECOMAX 25kW User Manual

1.3. Operators and supervisors

Boiler operators must follow the operation and maintenance manual. Any interventions with the boilers that could endanger
the health of the operators or those sharing the household are inadmissible!
The boilers may only be operated by persons above the age of 18 familiar with the manual and operation of the boiler.
It is inadmissible to leave children unattended near the boilers in operation.
When operating solid fuel boilers, it is prohibited to use combustible liquids to fire up as well as to increase the nominal power
while the boiler is in operation (overheating).
No combustible articles may be cast towards the stoking and ash pan openings and the ashes must be put away
in non-combustible vessels with lids.
The boilers in operation must be under frequent supervision of the operators.
The user may only carry out such repairs that consisting in the plain replacement of a spare part supplied (such as shaped fireclay
bricks, sealing cords, etc.).
While operating the boiler, caution must be exercised to ensure tightness of the doors and cleaning holes. These must at all times
be closed with care!
The user must not interfere with the structure and electric wiring of the boilers!
The boiler operators must regularly check the water filling level of the heating system and check the pressure meter function.
In the event of overheating, the operator must shut off primary air supply and collect the fire wood including the hot
charcoal into a non-combustible vessel. If the water has boiled out of the heating system, it must not be filled into
the boiler until after the latter has cooled down! Otherwise the boiler and the heating system will be damaged!
An overheated boiler and heating system may only be recommissioned after all boiler and heating systems have been
thoroughly checked (this particularly applies to all safety systems).
1.4 Type of environment
The boilers may only be used in the basic "regular environments" as specified by ČSN 33 0300. The boilers must be installed
in a boiler room where access of air required for the combustion process is ensured; the boilers must be based on a non-
combustible pad.
It is prohibited to position the boilers in residential spaces (including corridors)!
Warning:
In circumstances resulting in the risk of temporary ingress of combustible gases or vapours and while performing works
that might imply a temporary risk of fire or explosion (e.g. when gluing the lino, PVC, etc.), the boilers must be put out
of use in time and well in advance. No articles made of combustible materials may be placed on the boilers and within
smaller than the safe distance away from them!

Use

2.
The ECOMAX series hot water boilers are intended for heating villas or adequate production departments. The boilers must be
installed in specified working environments only.
The boilers are supplied in basic design controlled by an operating thermostat only and with electronic control which ensures
boiler power, control of the circulation pumps and, where relevant, control of the mixing valve.
The boiler must be operated in line with the requirements for the parameters of the chimney and the heating system.
The temperature of water returning to the boiler must not be less than 65°C. We recommend using a mixing valve and a water
storage tank.

Technical description of the boiler

3.
The core of the boiler is the body welded together out of steel plates. In the upper part of the body, a chute is fitted, equipped
with a closing stoke door. The lower part of the body is fitted with a circular combustion chamber with a closing ash-pan door. The
two spaces are mutually separated by a ceramic nozzle.
An air duct is provided in the frontal part of the body, which divides primary and secondary air. In the back part, there is
an exchange, a flue gas duct, a flue gas removal branch and cleaning holes. At the very bottom of the boiler body, there is a hole
of the filling and discharge valves.
Scanning sensor (pressure sensor, temperature sensor and safety sensor) beds and the hot water branch pipe issuing
into the heating system are welded on the top of the boiler body.
The boiler body is insulated with mineral felt and clad with protective covers. A discharge fan is connected to the smoke duct
outlet, where the purpose is to remove the flue gases towards the chimney. In the upper part of the boiler body there is a cooling
loop.
In the upper part of the flue gas duct, there is a chimney dumper controlled from the frontal part of the boiler.
Control and display elements contributing to the proper functioning of the boiler are installed on the boiler casing.
