Mounting and
Commissioning
• This heater can be mounted on a rain-protected
wall or under a roof. For outdoor installation
please install additionally the housing
(accessory).
• Start mounting by fixing the bracket of the
heater on the wall. Use the metal links between
bracket and reflector. Consider the safety
distances to combustibles to the top and to both
sides.
• In that case you want to install the housing
(accessory), then please fix first the second
bracket for the housing at the wall (the vertical
distance to the heater bracket is 123 mm).
• Now mount the heater by two metric screws /
washers / nuts M8 at the bracket link and by
fixing the screws adjust the radiant angle of the
heater (30° – 60°).
• For gas supply connect the flexible hose to the
gas valve.
• For electrical supply of the automatic heaters
4A and 7/2A connect the line 230 V, 50 Hz
to the control unit. For the 7/2A connect
additionally the second electrical supply cable
to the solenoid.
The ionisation and ignition cable are already
connected.
•
Check the gas inlet pressure:
Natural gas L: 25 mbar for Type 4
Natural gas L: 22 mbar for Type 4A and 7/2A
Propane: 50 mbar.
In that case you have a higher line pressure then
apply a governor (accessory). Ensure that all gas
connections are tight.

Service /
Maintenance
Regular maintenance is a requirement for troublefree operation. For safety reasons the maintenance
of gas heaters is therefore required and recommended.
The maintenance is to be carried out annually.
Depending on the operation conditions (e.g. dusty air
or sea side) we recommend maintenance in shorter
intervals.
Checks during service:
•
Check the heater with gas connections and
electrical connections concerning damage or
pollution, clean if necessary.
•
Check tightness of all gas connections, fittings
and components.
•
Check the safety function of the gas valve,
control unit, ignition and flame sensor.
•
Check the gas line pressure.
•
For faults read page 9.
•
Check the safety distances to combustibles.
