The minimum distance to the walls and ceiling required
according to the table of dimensions for proper cleaning
and maintenance of the boiler must be complied with.
A sufficient supply of fresh air must be provided directly
from outdoors into the heating room. Induced ventilation
is necessary for heating rooms that are confined or
enclosed.

The load-bearing capacity of the heating room floor must
be designed for the weight of the system plus filling with
water and fuel. The load-bearing capacity of the floor in
the area of the boiler bearing surface must be 512 lb/ft²
(2500 kg/m²).
IMPORTANT
Always follow the most up-to-date local, municipal and
building regulations and codes.

Ensure the mechanical room complies with the requirements
in these instructions.
Viessmann recommends the installation of an additional
electrical disconnect switch and a fuel shut-off valve (if
possible) outside the mechanical room or enclosed area
of installation.
A separate, dry heating room must always be provided for
the PYROT rotating combustion system. No combustible
materials may be stored in the heating room. The heating
boiler may only be set up on a fire- and temperature-
resistant floor.
No temperature-sensitive pipes or lines may be installed
in the floor beneath the heating boiler.
The temperature in the heating room must not exceed
104° F (40° C) while the system is in operation
(in the area approx. 3 ft. (1 m) away from the boiler).
The temperature in the heating room must not fall below
50° F (10° C) while the system is in operation (measured
at the inner side of exterior walls).
