Commissioning - instructions for contractual service organizations
Only professional mounting companies authorized to the performance of this activity may perform commissioning of the boiler.
6.1
Verification activities before commissioning
Before the boiler commissioning it is necessary to check:
1.
Filling of the heating system with water (a check of the manometer) and tightness of the system.
2.
Connection to the chimney
–
this connection can be only performed with the agreement of a corresponding chimney-sweep
company (chimney revision).
3.
Functionality of the thermostatic valve.
6.2
Commissioning the boiler
1.
Perform boiler kindling.
2.
Put the boiler to the needed operation temperature. Recommended temperature of output water is 60-
80 °C.
3.
Carry out a check of functionality of the safety device against overheating (of the final-cooling loop or DBV 1 - 02 two-way safety valve).
4.
Operate the boiler in an operational state according to the corresponding standard.
5.
Check repeatedly boiler tightness.
6.
Acquaint the user with servicing.
7.
Perform record into the warranty certificate.

Operating the boiler by user
The instruction manual of the regulator VERABORD 360 is supplied separately.
Wrong servicing and incorrect fuel combustion brings to damaging the product.
While first kindling of a cold boiler, water condenses in it and streams down by its inner walls. This fogging of the boiler drum will end
as soon as the boiler achieves the operation temperature.
While operating the boi
ler at temperature lower than 50 °C can occur fogging of the boiler drum, so called low-temperature corrosion,
which shortens the service life of the boiler heat-exchanger. That's why we recommend that you operate the boiler at temperature of
7
0 °C and higher.
HARD WOOD
To reach the nominal power of the boiler, it is necessary to observe maximum wood humidity of 20 %.
Fuel has to be stored in dry place.

The guarantee of clean and good combustion is the use of only dry and in-natural-state-kept wood.
In case of combustion of non-dried wet wood, its calorific value is being decreased, and it results in
an increase of fuel consumption and a decrease of boiler power! The practice shows that wood (in
case of logs from hard wood) is optimally dried by natural way after three years of drying. (for more
information, please refer, for example, to the Internet-portal of TZB-info).
