REMKO VRS-C Series
Selection of the installation
location
With determination of the instal-
lation location, the requirements
must be coordinated in regard to:
1.
Fire protection and operational
hazard.
2.
Function:
Space heating free-blowing or
with duct system.
Observe pressure conditions in
the installation room.
3.
Operational issues:
Heat requirement, air volume
flow, recirculation or fresh
air operation, humidity, air
distribution, room temperature,
space requirement.
4.
Facility for connecting to an
exhaust gas system.
Oil and gas-fired fan-assisted
heaters (also with a nominal heat
output of more than 50 kW) may
generally be installed outside of
heating rooms in compliance with
the FeuVo.
The building authority guideline
for the "Erection and installation of
combustion appliances" must be
observed.
For rooms in which highly flam-
mable substances or mixtures are
processed, stored or produced in
such quantities that ignition cre-
ates hazards, exceptions may be
permitted if suitable measures are
taken to ensure that the substanc-
es or mixtures cannot be ignited by
the combustion appliance.
With the installation of the units,
the local and country-specific
regulations (LBO)
and combustion plant order
(FeuVO) of the respective state
must be observed.
The first enactment of the
(German) Federal Emission
Control Act (1st BlmSchG)
and the statutory provisions of
the ordinance governing small
combustion plants
(1st BlmSchV) must also be
applied.
The fuel supply must be installed
in accordance with DIN 4755 for
oil-fired warm air heaters, DVGW
Code of Practice G 600 for gas-
fired warm air heaters and TRF for
liquid gas.
However, fan-assisted heaters in
particular are excluded from some
points.

Combustion air supply
Sufficient supply of combustion
air must be generally ensured by
the respective building authority
requirements.
Excerpts from the M-FeuVO (may
differ slightly per federal state).
(1) For room-air dependent
combustion appliances with
a total nominal heat output of
up to 35 kW, the combustion
air supply shall be deemed to
be verified if the combustion
appliances are installed in
a room that:
1. Has at least one door to
the outside or a window that
can be opened (rooms with
connection to the outside) and
a room volume of at least 4 m
3
per kW total nominal heat
output or
2 . Has an opening leading to
the outside with a clear cross-
section of at least 150 cm
2
or
two openings of 75 cm
2
each
or pipes leading to the outside
with cross-sections equivalent
in terms of flow.
(2)
For room-air dependent com-
bustion appliances with a total
nominal heat output of more
than 35 kW and not more than
50 kW, the combustion air
supply shall be deemed to be
verified if the combustion ap-
pliances are installed in rooms
that meet the requirements per
paragraph 1 No. 2.
(3) For room-air dependent
combustion appliances with
a total nominal heat output
of more than 50 kW, the
combustion air supply shall be
deemed to be verified,
NOTE
Only type-approved forced-air
oil burners in WLE design (per
DIN EN 267) or gas burners
(per DIN EN 676) should be
used.
NOTE
If the units are supplied from
the factory with an oil or gas
forced-air burner, separate
operating instructions for the
burner are enclosed.
CAUTION
The units must be set up and
installed in such a way that
they are easily accessible for
monitoring, repair and mainte-
nance work.
CAUTION
Overpressure and underpres-
sure in the installation area
should be avoided as this will
inevitably lead to combustion-
related malfunctions.
