Inspection
The panelling of the equipment
consists of metal and plastic parts,
which can be cleaned with a mild
(non-aggressive) cleaning agent.
When carrying out maintenance, only
original ATAG replacement parts may
be used.
Checks prior to commissioning
Changing settings such as burner
pressure and setting the amount
of air is not necessary.
Only in the case of failures or
replacement of the gas unit, venturi
and/or ventilator, does one have
to check and adjust the O
2
/ CO
2
percentage accordingly.
Following maintenance tasks
always check all gas-conducting
components on leakages by use
of leakage detection fluid (LDF).
