Boiler and burner must be distant and protected from parts of
flammable building materials and built-in furniture so that temperatures
of mentioned boiler heating capacity over 80 º C cannot occur.
Otherwise, you must maintain a distance of at least 80 cm.
Mouth for the air intake and outake must always be open, in its full cross section.
Air intake must be directly from outside. Air intake must be located 50 cm the most above
the bottom edge of the tank. The air intake mouth is preferably placed under the ceiling
on the outer wall of the boiler. If the boiler does not have outer walls, the ventilation
needs to be regukated by channel distribution. The air outake mounth must not have a
grid.
Minimum recommended distance from the wall for the assembly and maintenance
should
be
taken
from
the
manufacturer's
recommendations.
