STEP 8 FITTING THE GRILL
Ensuring the heater is central in the cut out, screw the grill to the front of the plinth heater
using the 2 shorter screws at point “A”. Then secure the grill to the plinth using the longest
screws at point “B”.
OPERATION
Switch the unit on at the socket. Set the top switch to “0”. Select the fan speed to “I” or “II”.
Turn on your central heating system. The fan will start to rotate provided hot water is circulating
through the heat exchanger at or above 43˚C. If the central heating system has just been
switched on there may be a delay in the fan starting until the central heating hot water reaches
43˚C.
When the central heating system switches off, and the system temperature drops below 43˚C,
the fan will stop automatically.
During the summer the plinth heater can be used for air circulation without heat. To do this Set
the top switch to the position “I” . In this position the fan will run until the unit is manually
reset.
