▷

Install flexible tubes or bellows units to prevent 
mechanical stress or transmission of vibration.

▷

Ensure that the seals are undamaged.

 DANGER

Risk of explosion!

 Ensure the connection is gas-

tight. 

▷

The gas insert can be rotated in 90° steps if 

necessary.

▷

We recommend that all the seals that are re-

moved 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 10 (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. We recommend that 
a double nipple to ISO 65 with a length of at 
least 5d be inserted into the connection.

Restrictors

▷

The appropriate restrictors are to be fitted in the 

supply lines for fuel gas, combustion air and 
motive air for the eductor to adjust the burner.

Central air connection for LPG operation

▷

The LPG version of the burner has an additional 

central air lance. 

▷

The gas lance must be cooled to prevent the 

gas cracking and soot forming inside the burner.

▷

The connection is made with an Ermeto pipe.

▷

The purging air connection must be located in 

the air supply line to the burner upstream of the 
air control valve, for example at the inlet of the 
air solenoid valve.

▷

Open the adjuster in the central air lance fully; on 
the ECOMAX

®

 1, the adjuster must be restricted 

to 45° or 50%.

Purging air connections for electrode and 

UV cell

▷

The electrode and the UV cell can be cooled 

and purged with air.

▷

The air must be branched off upstream of the 

air control valve, for example at the inlet of the 
air solenoid valve.

▷

Connect the purging air to the purging air con-
nection of the gas flange next to the electrode.
