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
®
0 to 3C, to prevent transport
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.
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.
