Clearances (mm)
Units must be installed so that the minimum clearances
in the following table are provided for combustion air
space, inspection and service and for proper spacing from
combustible materials.
Attention :
The clearance distance from the flue system must be
minimum 150mm at all points !

TECHNICAL DATA
Each blower motor is a three speed motor. The blower can be used on 3 different speeds. The units leaving the factory are
set to the standard speed as mentioned in table 4b. The curves as shown in the figures below, illlustrate for each unit which
speeds can be chosen in order to get another air duty. Speeds not illustrated in the curves mean that these are not applicable
(means : unit should not be set to that speed).
To use the blower on a different speed, the electrical connection of the blower motor needs to be changed. This has to be done
in the electrical connection box mounted on the blower itself. Inside the box, the 230V power supply wire is connected to the
terminal of the standard speed. For changing speeds, you have to reconnect this wire to the terminal that corresponds to the
desired speed (see wiring diagram inside service panel unit).
