Boiler with cooling spiral
Boilers can be ordered with a cooling spiral, and this must be used for installation with pressure expansion,
and in open systems if the pressure in the boiler is above 0.5 bar over pressure.
The cooling spiral must only be used as a cooling spiral; it must not be used for heating up water for other
use. Therefore the cooling spiral must be left empty during operation. Water supply for cooling spiral
maximum 15 °C. Pressure for cooling spiral minimum 2 bar, maximum 10 bar.
Responsibilities
The user is responsible for the operation of the boiler and ensuring compliance with the operational
guidelines supplied by CN MASKINFABRIK A/S. Failure to comply with the guidelines may result in reduced
efficiency and increased negative effects on the environment, as the boiler will not achieve as clean emission
gasses as intended. Furthermore, incorrect operation can reduce the working life of the boiler.
Correct operation and installation are the best guarantees for a well-functioning boiler with a long life and a
good environment. The user needs to have the necessary willingness and correct attitude to burning wood,
as it does, after all, take a bit of work to ”yield the crops” of this environmentally friendly and financially
profitable type of heating
Safety
If any faults or failures are found, they must be repaired as soon as possible by a boiler engineer. Flue pipes,
ventilation ducts, air holes etc. must not be closed off or blocked. Flammable liquids or combustible
substances must not be placed in dangerous proximity to the boiler.
For systems with an operational pressure above 0.5 bar over pressure (closed system with pressure
expansion or open system where the height from the boiler to the highest water surface is more than 5
meter), the boiler must be equipped with a cooling spiral connected to a cold water supply.
Boilers equipped with a cooling spiral must not be used (should be switched off) if the water supply is out of
order, or the water supply to the boiler is shut off (e.g. on the main tap).
Startup, manual stoking
1. Fill the boiler with the required amount of combustible material.
2. Light the fuel from below.
3. Adjust the air supply hatches (only until the right air supply level is found) only during manual stoking
without stoker.
•
Note.
Be very careful when opening the door to the boiler during operation due to extreme heat
inside the boiler and smoke emission.
Stop:
When the fuel material has been burned, the heat supply from the boiler stops.
