Maintenance
Always first unplug the heater
before any maintenance or
repairs.
Disconnect the gas hose from
the gas cylinder.
Regularly check that the gas
hose and its screw
connections are sealed. Only
original replacement parts and
hoses must be used. Hoses
must meet the specifications in
DIN 4815 Section 2.
Adjustment of the ignition
electrode should be checked
as shown in the adjacent
diagram.
Be sure to keep the safety
thermostat connection and the
thermoelement connections
clean. The connections may
become oxidized due to the
low electrical current flow,
which may influence the
correct switching of the safety
equipment and lead to the
destruction of the heater.
