Important Recommendation For Long-Lasting And Correct Operation Of The Boiler - Buroit PyroBurn Alpha Series Technischer Datenblatt Montage- Und Bedienungsanleitung

8.3. Important recommendations for long-lasting
EN
and correct operation of the boiler
- The allowed moisture content of the fuel used must
not exceed 15% ÷ 20%.
- Gas emission in the combustion chamber may result
in the formation of tar and condensate (acids).
Therefore, a mixing valve must be installed and it
must be adjusted so that the minimum temperature
of the water returning in the boiler is 65°С. This
extends the life span of the boiler and its warranty.
The operating temperature of the water in the boiler
must be within the 70°С ÷ 80°С range.
- It is not recommended to operate the boiler for a
long period of time at an output lower than 50%.
1. Due to unsealed connections
2. Due to accumulation of deposits. Condensate
and tar formation may reduce the performance and
life of the heating boiler. The temperature at the
boiler inlet must not be less than 65°C, boiler water
temperature at the outlet must be between 80 and
85°
3. Due to freezing
1. Insufficient draught
2. Heating value of the fuel is too low.
3. Presence of soot deposits and/or tar on the flue
damper in the upper chamber which prevent its tight
closure.
4. Presence of soot deposits and/or tar in the flue
pipes in water jacket in the back of the boiler

Cause
- When using circulation pump, boiler operation must
be controlled via a separate thermostat in order
to ensure the prescribed rated temperature of the
return water.
- The eco-friendly operation of the boiler is realized at
rated output.
- It is recommended to install a storage/buffer tank
and pump type group with thermostatic mixing
valve to the boiler. The capacity of the storage tank
is 55L of water per 1kW installed boiler power.
- Maintenance and operation training for the boiler is
conducted by an authorized installer.
Failure to observe the installation and
*
operating requirements described in the
manual and the service booklet voids the
warranty.
Installation damage
1. Install the connecting piping strain-free to the boiler
connections. Connect the heating installation outlet to
connection B. Connect the heating installation inlet to
connection A. Mount the cock Y included in the set item at
the drainage outlet / Diagram 13/
2. It is mandatory to install a three-way thermostatic valve
which will prevent the temperature dropping under 65°C
at the inlet.
- In order to increase the operational life of the boiler it is
recommended to install a buffer vessel with capacity of 55
l per 1 kW of installed power
3. If the heating installation, including the piping network,
has not been built frost-proof, we recommend that you fill
the heating installation with a liquid which has low freezing
point and corrosion protection and antifreeze agent
Output is too low
1. Check chimney condition and measure draught. (must be
performed by an authorized service)
2. Make sure you use sufficiently dry fuel. When using fuel
with high moisture content, after the reloading the boiler
may burn for some time at significantly lower output level
until the fuel in the combustion chamber has dried.
3. Clean the flue damper and make sure that when moving
its closing/opening lever it provides adequate sealing of the
flue gas outlet in the upper chamber. (must be performed
by an authorized service)
4. Clean the heat exchange surface of the flue pipes using
the brush from the cleaning tools set. After the cleaning
is completed, remove any soot through the inspection
opening in the back of the boiler. Must be performed by an
authorized service.
