IMPORTANT INFORMATION FOR INSTALLATION
g
as
cOnnectiOn
The applicable regulations and provisions must be complied
with. In all cases, a shut-off valve must be placed as close to the
boiler as possible. A filter must be provided on the gas supply
immediately downstream of the shut-off valve.
The diameters of the pipes must be defined in accordance with
the local regulations.
Gas supply pressure
- 20 mbar with H natural gas,
- 25 mbar with L natural gas,
- 300 mbar with H or L natural gas with pressure regulator to be
supplied as an option.
Note
In a boiler room with a total output > 260 kW, the pressure
regulator must be fitted outside of the building.
Gas buffer tanks
Gas buffer tanks is one of the solutions used to resolve the issue
of accidental triggering of the "min." or "max." pressure switches
fitted to gas burners.
Triggering is linked to the inertia of the fluid-expansion system
which causes pressure drops and surges in the gas supply line
when burners are started up and shut down.
The volume of a buffer tank can be calculated using our
software offering, in particular DIEMATOOLS, which can be
accessed from our specific website for industry professionals.
Installation
If possible, the boiler's protective packaging must only be
removed once the boiler has reached its final installation
location. Without packaging, the boiler measures 60 cm in width,
and can fit through all standard doors. The weight of the boiler
exceeds the maximum weight which can be lifted by one person;
use of lifting equipment is recommended.

cOnnectiOn
This must comply with the local regulation.
The boiler must be supplied via an electrical circuit which
includes an omnipolar switch with an opening gap distance of
> 3 mm. Protect the network connection using a 6A fuse.
Note:
- The sensor cables must be separated from the 230 V circuits
by at least 10 cm,
- To protect the antifreeze and anti-blocking functions of the
pumps, we recommend that the boiler is not powered off
using the mains switch.
- Based on the quality of the power supply network, we
recommend that an isolation transformer is used.
