Set-up and installation
4.4.2 Setting up the unit
Precondition
– The installation site complies with the respective country-spe-
cific regulations, as well as the minimum requirements
described in section 4.4.1.
– Install a leakproof tray on site if using a pressure device and
secure the unit using a float switch.
Set-up
Ɣ
Remove the packaging and dispose of it in an environmen-
tally sound manner.
Ɣ
Install ROTEX A1 BO at the place of installation. Do not lift or
move the unit holding the panels.
Ɣ
Position the ROTEX A1 BO so that it can be hinged open
without any restriction.
Observe the connection points of the oil hoses and the
mounting position of the oil filter, line routing of the heating
lines and the flue gas line.
Ɣ
Check for the horizontal level and correct installation height of
the ROTEX A1 BO. You can adjust the height with the four
height-adjustable feet.
4.5 Air/flue system (LAS)
4.5.1 General instructions for flue system
The Firing Ordinance of the respective state and EN 15287 are
valid for the model and dimensioning of the flue system.
Minimum requirements
For the design and dimensioning of the flue gas system, observe
all valid national combustion ordinances and country-specific
regulations.
Basically, for the flue gas system, you can use each flue gas pipe
according to EN 14471 with EU label, which meets the following
minimum requirements:
– Suitable for heating oil.
– Suitable for flue gas temperatures of at least 120 °C (temper-
ature class T120 or higher).
– Suitable for at least 200 Pa overpressure (pressure class P1
or H1).
– Humidity-resistant (condensation resistance class W).
– Sufficiently corrosion-resistant (corrosion resistance class 2).
The features of the flue system must be recognisable on the in-
stalled system.
Ɣ
Place the nameplate of the flue system in the installation
room.
Type of connections
– Straight, directly towards rear:
SET C,
15 50 79.03
.
– Height offset, towards rear:
SET D,
15 50 79.04
.
– Direct roof penetration:
SET F,
15 50 79.06
.
For other details and connection dimensions for the three ver-
sions of the flue gas pipe, see section 4.5.3.
– Each flue gas line must be installed with a suitable test
adapter for checking and setting the combustion values. The
ROTEX LAS construction sets each include a test adapter
(
D8 PA
,
15 50 79.00 93
).
Installation position and line height
– The maximum permitted flue gas counter pressure is
200 Pa
.
The pressure loss in the supply line must not exceed
50 Pa
.
– Angle of entry of the flue gas pipe into the chimney or instal-
lation shaft:
3°
.
– Slope for horizontal parts of the flue gas pipe:
3°
.
Counter-slopes are not allowed at any point in the flue gas
pipe.
– If the flue gas pipe needs more than 3 deflections >45°, then
the maximum permitted height for the flue gas pipe is reduced
by at least
1 m per deflection
(flue gas calculations may be
needed).
– If the horizontal connecting piece is extended, the maximum
permitted height of the flue gas pipe is reduced by exactly that
length.
– Flexible flue gas lines must not be used in horizontal connec-
tion sections.
Flue gas system resistance
To ensure safe burner start-up and stable setting values, a
minimum resistance is required in the flue gas line. If this is not
achieved you need to fit a silencer (
E8 MSD,
15 45 78
or
E11 MSD,
15 45 79
).
Ɣ
Switch the burner on (see chapter 15.2 "Emissions
measurement").
Ɣ
Measure the resistance with a differential pressure
measurement unit on the flue gas measurement location
between the flue gas and intake air measurement openings
(differential pressure for the A1 BO 15/20 at least 0.5 mbar,
for the A1 BO 27/34 at least 1 mbar).
The tab. 4-3 and the tab. 4-4 show the maximum permissible
height of the flue gas line in the event that the ROTEX A1 BO is
operated in the nominal output range.
1) Cross section of the shaft: 135 mm x 135 mm
Tab. 4-3 Maximum permitted height of the flue gas pipe in m (when
operating in the nominal output range) - A1 BO 15-e to 27-e
WARNING!
There will be a
risk of poisoning
caused by flue gas
escaping within enclosed rooms that are inadequately
ventilated.
Ɣ
Install only approved flue gas systems.
Ɣ
The stipulated ventilation and rear ventilation must
be ensured, depending on the set up variant.
We recommend using the associated ROTEX flue gas
kits. ROTEX They satisfy all requirements and are also
fitted with special acid-proof seals.
