8.6 CONVECTION AIR BLOWER
The convection air blower (optional component) is screwed on to the com-
bustion air box.
• Remove the power plug from the socket
• Remove the back wall.
• Unscrew the cover plate of the fuse box.
• Pull the cable lug from the blower motor.
• Remove the geared motor.
• If necessary unscrew the side part of the cladding
• Remove the convection air blower.
The assembly is carried out in the reverse order.
8.7 FLUE GAS TEMPERATURE SENSOR
The flue gas temperature sensor is secured to the outlet of the flue gas fan
using a squeeze-type threaded joint.
• Remove the power plug from the socket.
• Remove the back wall.
• Undo the squeeze-type threaded joint and pull out the sensor.
• If this should block, unscrew the flue gas sensor on the controller, pull
back the line to the flue gas fan and now unscrew the complete screw
fitting. In doing so, the cable turns and without previous unscrewing and
pulling back, it would break.
• If not carried out yet, disconnect the flue gas sensor from the controller.
The wires are red and green.
