Installation instructions for air box
rotation on the EK EVO 8/9 burner
By default the air box opening on the EK
EVO is pointing in the direction of the
boiler. However, if an air duct connection
is provided, it is possible to orient the air
box, with certain adjustments, in the
direction of this duct. In principle the air
box can be turned from its basic position
in 45° increments, up to 180°, in an
anticlockwise direction. The
corresponding procedure is described
below.
1. Removing the servomotor
In order to remove and reinstall the air
box in a different position, it will be
necessary, prior to doing so, to remove
the air flap servomotor. Remove the 4
M5 servomotor screws and loosen the
screw on the air flap shaft coupling to
remove the drive. The length of the drive
cable has been designed for the basic
position. For other positions, other cable
lengths are required, and in part will be
routed to other attachment points. By
opening the cable clamps and pulling
the cables up to the switch cabinet,
sufficient cable length can be obtained.
2. Removing the air box grille
Remove the air box grille, in order to
access all the screws on the air box. To
remove the air box grille, loosen 2
screws on the underside and 2 nuts on
the upper side.
3. Using lifting equipment
The use of lifting equipment (lifting
crane, lifting table, or equivalent)
facilitates air box removal. When a lifting
crane is available, it is possible to affix a
lifting ring (M8) to the air box in the
space provided for this purpose.
Remove the bolt for this. In this case, the
air box can be removed by one person.
Without lifting equipment, the presence
of a second person during air box
removal is advised (air box weight is
around 37kg).
4. Special notes for using a frequency
converter
When using a frequency converter for
the burner blower, a Namur sensor is
integrated for recording and transmitting
the feedback signal to the control box. In
this case, disconnect the Namur sensor
cable (blue cable) in the switch cabinet
and pull it up to the air box before
removing the latter.
5. Removing the air box
Then proceed with the removal of the air
box by loosening the screw connections.
If a Namur sensor is integrated, pay
03/2016 - Art. Nr. 4200 1044 8002A
close attention to it. Pull the cable in the
direction of Namur sensor, so as not to
damage the cable.
