The heaters are designed to take their input air from the ceiling void. It is, therefore, imperative that a suitably sized inlet grille is provided within the ceiling or enclosure. The minimum clearance to the top inlet grille is 20mm, to the back 30mm and to the front inlet grille 100mm. If one inlet grille is at its minimum dimension the other must have an unrestricted airflow.
For optimum effect the heater should be mounted as close as possible to the top of the doorway. The maximum recommended mounting height is 2.3m for 3kW and 2.8m for 4.5kW, 6kW and 9kW units.
It is recommended a frame is provided around the ceiling opening. The adjustable brackets then allow fixing to the top of this frame or to the face of the ceiling. Alternatively, holes are provided in the top of heater for drop rod fixings.
The grille frame is fixed directly to the ceiling to provide a decorative finish.
3kW, 4.5kW and 6kW units are only suitable for connection to a 230V single phase power supply. The 9kW is suitable for both a 230V single phase or 400V three phase and neutral supply Connection should be made to a suitably fused power supply via the remote switch unit. 4.5kW, 6kW and 9kW must be connected directly to the power distribution board. Connection should be via a 2 pole switched connection unit having a contact separation of at least 3mm in all poles.
All electrical connections should be made by a suitably qualified person in accordance with the latest edition of the IEE Requirements for Electrical Installation (BS 7671:2008).
