3.   Installation Details

3.1 Mounting

The Reznor recessed ceiling heaters are designed to fit in place of a standard 

600mm ceiling panel.

It is essential that the ceiling frame is adequately supported to support the weight 
of the heater, or that the heater is individually supported. There is provision on the 
heater for chain or wire, support or mounting.

• 

The weight of the ACT03 – RX, ACT04 – RX is 7kg

• 

The weight of the ACT06 – RX is 10kg

It is the sole responsibility of the installer to ensure that the points of attachment to 
the building are sound. Care must be taken to allow complete free air movement 
into the inlet grilles of the unit to ensure the correct working operation of the heater. 
Carefully unpack the unit. 

The unit is supplied with a length of self–adhesive foam strip. This can be cut into 
lengths and is to be laid on the 4 sides of the ceiling frame. This will ensure that the 
unit assembly is free from vibration. The discharge grille and diffuser assembly can 

now be fitted into the ceiling frame.

The wire or chain used to mount the 
heater can be attached to 4 of the M6 
studs or the 4 x M6 threaded inserts as 
shown in diagram.

Ensure the air outlet of ACT03 – RX and ACT04 – RX is 
nearest to the wall or corner.
