Installation
CAUTION
We recommend that lifting gear be used for instal-
lation due to the weight involved.
Please observe the following to ensure that the
ECOMAX
®
is not damaged during installation and
operation:
▷ Dropping the device can cause permanent dam-
age. In this event, replace the entire device and
associated modules before use.
▷ With the ECOMAX
®
damage, the ceramic air guide tube LFR is sup-
plied separately or is fitted with extra transport
protection. See enclosed documentation.
Installation on the furnace
▷ The burner has three air connections and one flue
gas connection. During installation, the burner
must be aligned appropriately (flue gas upwards
or to the side).
ECOMAX
®
for direct heating systems
▷ For a direct heating system, the flue gas guide
tube FGT set..D and the eductor EJEK are re-
quired, see page 16 (Accessories).
EJEK
FGT-Set..D
Remove the transport safety device.
▷ The installation opening in the furnace wall must
be greater than the outside diameter of the FGT.
▷ Do not stress the FGT with forces from the
furnace lining. Wrap the FGT in a fibre blanket
before installing the burner.
0 to 3C, to prevent transport
Complete the fibre wrapping to match the ap-
erture in the furnace wall. Depending on the fur-
nace lining and the type of expected movements
in the furnace wall, the annular void must be at
least 25 mm. Use a larger annular void if neces-
sary. Wrap the cut to size fibre blanket around
the FGT. Fasten the blanket over its entire length
using conventional adhesive tape (compress it
to around 50% of its thickness). After commis-
sioning, the adhesive tape burns off and the fibre
blanket expands evenly inside the annular void.
▷ Slide the FGT over the recuperator if it has not
yet been installed.

▷ When installing, always ensure that when the
burner is mounted, it is sealed tightly on the
furnace.
Installing the eductor
▷ The eductor is mounted to the side of the burner.
▷ Align the eductor's pressure test point to the
control side.
