Safety temperatures
The boilers comply with EN 303 and DIN 4702, and are all CE-desig-
nated and can be used in sealed heating systems as per EN 12828.
■ Permissible flow temperatures (= safety temperatures):
up to 110 ºC
To EN 12953: up to 120 ºC
■ Max. possible flow temperature:
approx. 15 K below the safety temperature
■ High limit safety cut-out of the boiler control unit:
Delivered condition 110 ºC
Adjustable to 100 ºC
6.2 Delivery
KÖB delivers to the site. The system is unloaded on site.
A special crane is required on site for unloading.
The personnel carrying out transportation must be aware of accident
hazards and take appropriate measures to prevent them. The boiler
should only be lifted when it is completely empty (water, fuel, ash).
Pyrot with a rated output of 100 – 300 kW: lift by lifting eye.
Pyrot with a rated output of 400 – 540 kW: lift by flow and return con-
nectors with tie-bar.
6.3 Handling
A number of lifting eyes will be provided on each boiler and flue gas/
water heat exchanger where lifting gear may be attached.
To lift the boiler by the flow and return connectors, a tie-bar is
required.
Our experts can undertake the handling and installation on prepared
foundations upon request (chargeable option).
The boilers may be placed onto concrete without special foundations.
Observe the installed boiler height.
Minimum clearances to walls for installation and maintenance work
must be observed.
Anti-vibration boiler supports may be used if anti-vibration measures
are required.

6.4 Siting
Requirements for boiler room
A separate dry boiler room must be provided for the system. No com-
bustible materials should be stored in the boiler room. The wood boiler
may only be installed on a fire and temperature-resistant floor. No
temperature-sensitive pipes or lines should be routed under the floor
under the boiler. The load bearing capacity of the boiler room floor
should be sized to the system weight plus the water fill volume and the
fuel. Floor load bearing capacity in the area of the boiler supporting
surface: 2000 kg/m².
The minimum clearances from walls and the ceiling, which are required
for cleaning and maintenance, must be observed. These can be found
on the measurement sheet. An adequate fresh air supply directly from
outside into the boiler room must be ensured. If the boiler room is nar-
row and/or internal, forced ventilation is required. The temperature in
the boiler room when operating the system must not exceed +40 °C
(measurement point: boiler environment approx. 1 m away from
boiler). The temperature in the boiler room when operating the system
must not fall below +10 °C (measurement point: inner side of external
wall).
