operation!
2.3 Operating tips
When operating the heating system observe the following:
V The boiler may only be operated by adults who are
familiar with the instructions and boiler operation.
V Make sure that children are not allowed in the vicinity of
the boiler unsupervised when it is in operation.
V Do not use any fluids for lighting or boosting the boiler.
V Ashes should be placed in a steel container with a tight
fitting lid, and moved outdoors. Other waste must not
be placed in this container.
V Do not place or store any flammable objects near the
filling or combustion chamber or at a safety distance of
24 to 48 inches around the boiler.
V Do not place any flammable objects on the boiler.
V Only clean the surface of the boiler with non-flammable
cleaners.
V Do not store any flammable materials in the boiler room
(e.g. petroleum, oil).
V Do not use any flammable liquids for heating.
V While the boiler is operating, do not exceed the rated
output of the boiler (overheating).
V Operate the boiler at a maximum temperature of 194 °F
and check it regularly during operation.
V Operate the boiler with a minimum return temperature
of 131 °F. Ensure that this temperature limit is adhered
to with a suitable set-up.
V The minimum boiler water temperature must be above
131 °F, because with a lower temperature, steam can
condense. This has negative consequences for the
proper operation of the boiler and its life span.
V The boiler operator must follow the operating instruc-
tions.
V The boiler operator may only start up the boiler, take the
boiler out of operation, and clean it. All other work must
be performed by an authorized service company.
V The service technician is obligated to inform the boiler
operator about the operation and the correct, safe
operation of the boiler.
V In case of danger of explosion, fire, escaping combus-
tible gases or vapors (e.g. vapors that arise when gluing linoleum, PVC, etc.), do not operate the boiler.
V Heed the flammability of building materials
(Æ installation and maintenance instructions).
2.4 Air supply
DANGER: Risk of fatal injury from lack of
oxygen in the boiler room!
V Make sure there is adequate fresh-air ven-
tilation by providing air vents to the outside.
V Point out to the system operator that
those air vents must remain open.
WARNING: System damage and risk of
injury in case of incorrect start-up!
Lack of adequate air for combustion can lead
to creosote formation.
V Make sure there is adequate fresh-air ven-
tilation by providing air vents to the outside.
V Point out to the system operator that
those air vents must remain open.
WARNING: Risk of system damage due to
aggressive materials in the ventilation!
During combustion, halogenated hydrocarbons that contain chlorine or fluorine compounds cause increased corrosion in the
boiler.
V Keep ventilation free of aggressive materi-
als.
The boiler draws in the required combustion
air from the environment. The boiler may only
be set up and operated in rooms that are permanently well-ventilated!

2.6 Product description
The Logano G201 is a solid fuel boiler and approved for
fueling with coal and wood chunks.
The boiler consists of:
–Air vent [1]
– Ash pan door [2]
– Fuel filler door [3]
– Firing controller [4] with rod and chain
– Aquastat [5]
– Manifold [6] with safety valve and thermometer/
manometer.
Using the firing controller [4], the desired boiler water
temperature is set and limited to this maximum value.
The firing controller [4] is connected to the air vent [1] via
a chain (in the ash pan door) and regulates the airflow of
the boiler. The warmer the boiler becomes, the more the
air vent is closed so that the set boiler water temperature
is not exceeded.
The fuel filler door [3] allows you to fill the ignition chamber with fuel.
The ignition chamber transmits the heat generated to the
heating water.
The ash container is behind the ash pan door [2].
The thermometer/manometer on the manifold [6] displays
the temperature in the boiler and the water pressure.
The jacket is lined with insulation materials and thus prevents radiation loss and stand-by heat losses.

Exhaust flap
The exhaust flap is opened to heat up a cold boiler or in
case of poor flue draft (Æ Fig. 2 above). This allows hot
flue gas to escape more quickly into the chimney and the
chimney "draws" better.
When the boiler is operating normally and when there is
sufficient flue draft, the exhaust flap is closed (Æ Fig. 2
below). This way, less heat is lost through the chimney.

General instructions about the fuels wood and coal
3 General instructions about the fuels wood and coal
Wood and coal can be used as fuels.
DANGER: Danger of fatal accident due to
escaping carbon monoxide (CO)!
In case of firing with brown coal, the boiler
can silt up and CO can escape.
V Do not use brown coal for firing.
WARNING: Health and/or system damage
due to the use of unsuitable fuels!
The use of unsuitable fuels can create materials that endanger health and/or the heating
system.
V Do not use plastics, household waste,
chemically-treated wood, old paper, chips,
bark or chipboard waste for firing.
The flue gas temperatures are generally 212 – 392 °F.
Depending on local conditions, fuels used (wood or coal),
and how clean the boiler is, these values can be
exceeded.
3.1 Wood firing
Prescribed is split and dried wood with a diameter of
6 inches and a maximum wood humidity of 20 %.

3.2 Coal firing
Best suited are anthracite coal and coke – any kind of
lump 1 (0.8 – 1.6 inches). The burning times for coal are
significantly longer than the burning times for wood.
As substitute fuels, the following are permissible (reduced
output and shorter maintenance intervals): anthracite coal
and coke type lump 2 (0.4 – 0.8 inches) or fragments
(1.6 – 4.0 inches) and pressed fuels.
Maximum length of split
Boiler type
27 15 ¼ inches
35 19 ¼ inches
40 27 ¼ inches
Tab. 1 Maximum length of split or chipped wood
Only use dry, natural, chunky wood. With a wood humidity
of more than 20 %, the boiler output is reduced. In addition, there can be increased tar formation, which reduces
the life span of the boiler. The specified output values and
the unfettered function of the boiler can only be guaranteed with a maximum wood humidity of up to 20 %.
or chipped wood
3.3 Condensate and tar formation
Improper operation of the boiler causes excessive condensate and tar formation. This way, damage to the boiler
and the flue gas system can occur.
When heating up the cold boiler, water condenses in the
boiler, which runs down on the interior walls. This way,
you might think that the boiler is draining off. This "sweating" of the boiler ends as soon as the ashes accumulate
on the interior walls of the boiler.
In case of operation at low boiler temperature (return temp
less than 131 °F) and fuel with too high a humidity content, condensation can also form on the heating surfaces.
Here too, the condensation runs downwards.
Heating with too low a boiler temperature causes tar formation and can cause premature damage to the flue gas
system due to sooting.
V Follow the operating instructions for the boiler.
V Operate the boiler at the recommended operating tem-
peratures.
V Only heat the boiler with the recommended fuels
(Æ Chapter 3.1 and 3.2).
V Remove tar accumulations with the cleaning scraper
when the boiler is warm.
