Installation
Connecting the Vacuum sensor hose
If the FireBOX is going to be connected to a BOFA
Autoflow extraction unit then an additional sensor
tube MUST be connected. The sensor tube should be
run from the outlet of the FireBOX to the inlet of the
extractor. (run inside the flexible hose)
The following procedure must be carried
out with the electrical supply isolated.
1: Attach and secure the sensor tube to the small
standpipe located inside the extractor inlet.
2: Run the sensor tube through the flexible hose and
cut to length.
3: On the FireBOX there may be a black rubber cover
over the small sensor standpipe. (on the firebox inlet)
this
must
be removed.(see picture below)
4: Attach and secure other end of sensor tube to the
FireBOX outlet.

The connectors should be attached to the standpipe
inside the 75mm port on the FireBOX with the sensor
tube attached. The sensor tube should then be run
inside the 75mm hose and connected at the other end
to the BOFA extraction unit.
