REMKO VRS
The heaters must be connected to
a suitable and approved chimney
system.
Chimney systems are structural
systems in or on buildings which
are solely intended for discharging
exhaust fumes from heat generat-
ing systems safely via the roof.
The following are of particular
importance for the planning and
erection of chimney systems:
■ The respective Ordinance on
Firing Installations (FeuVo),
■ The respective building regula-
tions (LBO).
■ DIN 18160, part 1, design and
performance.
■ DIN 4705, part 1, calculation of
firing installations.
■ Technical directives for gas
installation DVGW-TRGI 1996
For the design and installation of
chimney systems, the following
must be observed:
■ Installation and erection of the
chimney system must be carried
out professionally and in com-
pliance with the respectively
applicable regulations.
■ The dimensions of the chimney
pipe must correspond to the
power of the unit, structural
conditions and specific require-
ments.
Annual inspection
and maintenance
Depending on the particular
operating conditions, the heating
appliances should be inspected by
an expert for reliable operation as
necessary, however at least once a
year.
The operator is obliged to have
the heating appliances inspected
at least once a year for correct
operation, reliability, efficiency and
maintenance of emission limits by
a representative of the manufac-
turer or other authorised specialist.
The measurement of combustion
values must take place in accord-
ance with the statutory require-
ments of the Federal Immission
Control Act (BImSchV).
Where faults are discovered,
the operator must be notified
that he is obliged to arrange for
immediate repair or replacement of
components.
The following applies:
Repairs to limiting devices, auto-
matic actuators, flame monitoring
devices and other safety devices
must only be carried out by the
respective manufacturer or his
representative on the individual
device.

■ Chimney systems must be di-
mensioned according to internal
cross-section and height so that
the exhaust fumes are dischar-
ged to the outside in all normal
operating conditions and no
dangerous positive pressure can
occur with respect to rooms
■ The outlets of chimney systems
must rise minimum 40 cm abo-
ve the ridge or be minimum 1
m away from the roof.
■ Where dynamic pressures are to
be expected, e.g. due to down
winds or from neighbouring
buildings, the chimney coping
must be designed appropriately.
■ In the case of roof or wall
openings, the chimney system
must be lead through tubular
sleeve or shaft to enable free
expansion of the chimney pipe
on heating.
■ Connection of the heating ap-
pliance must take place tightly
sealed and protected against
accidental loosening by means
of rivet or screw.
■ Horizontal chimneys should
preferably be kept as short as
possible.
■ A reclosable measuring open-
ing must be provided in the
chimney pipe downstream of
the appliance connection at a
distance of 2 x D ( Ø).
NOtE
The erection of the chimney
system requires permission in
any event.
AttENtION
It must be ensured that no
back pressure occurs due to an
incorrectly installed chimney
duct.
NOtE
It is recommended to conclude
a maintenance contract with
an authorised specialist com-
pany for regular maintenance
and cleaning.
