All CN boilers must be installed according to the Installation and Assembly
Guide below.
If the boiler is not installed in accordance with the installation instructions in the
user manual, it is the responsibility of the installation engineer to submit the
boiler unit to a construction test (module B1) or install the boiler unit in
accordance with a system of full quality assurance (module H) according to the
Pressure Equipment Directive 97/23/EEC. In both cases, an authorised body after
your own choice must be contacted.
Function
•
The CN boiler is a triple-flue boiler constructed on the basis of many years’ experience and testing.
•
The CN boiler is constructed with a large cylindrical fire chamber, specially developed for firing with
stoker, wood, wood chips, saw dust, peat, paper, coal or coke etc.
•
The convection part of the CN boiler is placed on top of the fire box in the hottest part of the boiler,
which consists of many smoke gas sections surrounded by water.
•
The construction and dimensions of the CN boiler thus create an efficient use of the smoke gas
before it reaches the smoke outlet
•
The large doors of the CN boiler, which open both the fire chamber and the smoke ducts, make
cleaning the boiler very efficient and easy.
•
Optimal, environmentally friendly and highly efficient burning of the wood requires correct ratio
between the combustion air and the smoke gasses from the fuel.
•
The boiler is constructed with a large door to enable the burning of large objects.
•
Acidifying substances such as plastic (PVC) must not be burned in the boiler, as they produce
hydrochloric acid fumes during combustion (HCL).
•
Basifying substances must not be burned in the boiler, as they corrode the boiler during combustion.
•
It is important that the feeding of fuel is adjusted to allow the heat from the wood to be contained in
the heat reservoir at all times. The stoking should be adjusted so that the fuel has just been burned
when the heat reservoir reaches its maximum temperature.
•
The boiler efficiency is larger when the boiler can deliver the heat without having to shut off the air
supply too much.
