Delivery, handling and installation
Delivery
We deliver the equipment to site by a
vehicle with a crane facility and will
unload the equipment without special
requirements.
Handling and installation
If Vitogas 100 is delivered as block
assembly, a number of lifting eyes will be
provided, where lifting gear may be
attached. Handling presents no special
difficulties if Vitogas 100 is delivered in
individual sections.
The boilers may be placed onto a level
concrete floor without special
foundations.
However, to facilitate the cleaning of the
boiler room, it is appropriate to position
the boiler on a plinth.
Upon request, a Viessmann installation
engineer may assist in the assembly
(chargeable). For this purpose, the
sections must be located in the
installation area.
For recommended minimum distances
from walls for installation and
maintenance work, see Vitogas 100
datasheet.
