IMPORTANT
Take care that installer is a trained experienced
service person.
Turn off gas supply before starting installation.
Disconnect power supply to prevent electrical shock
and/or equipment damage.
Do not remove seals over inlet and outlet until the
device is ready to be installed.
If M5 air pressure connection is not to be used, it is
recommanded to push a dust cap into the hole.
Mounting position
The gas control can be mounted 0 to 90
°
in any direction
from the upright position, i.e. from the position when electric
coils are on top.
Main gas connection
IMPORTANT
During tightening the main gas connection assure
the gas control is secured against rotation by using
the right spanner in order to ensure right mounting
position and avoid excessive forces (see figure 5).
Ensure the gas flows in the same direction as the
arrow on the bottom of the gas control.
