When installing, ensure that the components
are sealed tightly.
▷
Ensure that no lateral forces act on the burner
recuperator.
Heat guard
▷
During operation, the burner body and eductor
or flue gas connector can reach surface tem-
peratures of over 80°C.
▷
We recommend that warning signs and a contact
guard be fitted, for example made of perforated
sheet metal.
▷
Do not insulate the burner body, eductor and flue
gas connector to prevent material overheating.

* On the ECOMAX
®
..L for LCV gas, connections
may differ depending on the project specifications.
▷
Install flexible tubes or bellows units to prevent
mechanical stress or transmission of vibration.
▷
Ensure that the gaskets are undamaged.
DANGER
Risk of explosion! Ensure the connection is air-tight.
▷
The gas insert can be rotated in 90° steps if
necessary.
▷
We recommend that all the gaskets that are
removed to rotate the gas insert be replaced.
▷
The electrode must remain in its position at the
top left when the gas insert is rotated. The mixing
device (gas lance) must be rotated for this pur-
pose, see page 11 (Replacing the gas lance).
▷
If necessary, another air connection may be used.
The burner has three air connections, two of
which are sealed with blind flanges.
▷
Ensure undisturbed flow to the orifices in the air
and gas connections. The ECOMAX
®
is delivered
with a connection set for gas. In the air circuit,
we also recommend the use of a connection set
for air, see page 16 (Accessories).
