1. General Information
1.1 Introduction
This instruction manual describes the Reznor Recessed Warm Air Ceiling Heaters.
The heater is designed for discreet positioning in a suspended 600mm ceiling within
retail or commercial premises. It can t a recess as shallow as 210mm.

All installations must be in accordance with the regulations in force in the country of use.
These instructions must be handed to the user on completion of the installation.
Installers and service engineers must be able to demonstrate competence and be
suitably qualied in accordance with the regulations in force in the country of use.
To ensure continued and safe operation it is recommended that the appliance is
serviced annually.
The heater outlet / inlet must not be obstructed during use.
1.3 Electrical Supply
Electrical supply is 230/240V single phase, Neutral and Earth. The maximum cable
inlet size is 4mm².
It is recommended that the electrical supply to the base unit in the heater is via
an appropriate switched isolator in accordance with the regulations in force in the
country of use and must be via a fused isolator having a contact separation of greater
than 3mm on all poles.
All units must be wired in accordance with I.E.E regulations for the Electrical
Equipment of Buildings and the installer should ensure that a suitable isolating switch
is connected in the mains supply.
1.4 Controller `RX` models

1.5 Location
All units should be installed horizontally. It is recommended that the ceiling heater is
installed within the ceiling void or roof space.
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. If the ACT03 – RX
or ACT03 – RX/ ACT04 – RX heaters are mounted close to the wall or corner the
discharge opening should be facing the wall. The minimum distance from the wall or
corner is 0.8m or 1.2m for the ACT06 – RX.
1.6 Clearance distances
It is recommended that a minimum clearance of 50mm is allowed around the case
and 30mm above the heater. The clearance allows for cable entry and prevents
combustible surfaces overheating.
The minimum mounting height (oor to grille) is 2.2m for the ACT03 – RX, ACT04 –
RX and 2.5m for the ACT06 – RX. The recommended mounting height is 2.5m for the
ACT03 – RX, ACT04 – RX and 3m for the ACT06 – RX.
1.7 Clearance distances
1.8 Health and Safety
Sole liability rests with the installer to ensure that all site safety procedures are
adhered to during installation.
Sole liability rests with the installer to ensure that protective safety wear such as
hand, eye, ear and head protection is used during installation of the product.

3. Installation Details
3.1 Mounting
The Reznor recessed ceiling heaters are designed to t 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 tted into the ceiling frame.
Fig.2 Air discharge of ACT06 – RX
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.

6. Servicing & Maintenance
6.1 Maintenance
Always ensure that the main external electricity supply is switched off before
commencing any maintenance on this heater.
To obtain the best results from the heater, it is essential to avoid the accumulation
of dust and dirt within the unit on the air inlet and discharge grilles. For this reason
regular cleaning is necessary.
• Cleaning of the fan is best carried out with a soft brush.
• The product should be serviced annually.
• Servicing shall be undertaken by a competent person.
6.2 General
If the heater does not operate a competent service engineer should be called to
identify the nature of the fault.
All heaters are tted with motor thermal protection.
Other faults in relation to the element, motor and wiring should be identied using
conventional fault nding techniques.
In the event that electrical components are replaced, please ensure that electrical
safety checks in accordance with the regulations in force in the country of use are
undertaken.
6.3 Thermal cut–out
The units are protected from overheating in the event of fan failure or an obstruction
of the free airow, by thermal cut outs. If this happens the thermal cut outs switch off
the appliance. The appliance will not operate until the heater is disconnected from the
mains supply and it has cooled down.
If this fault re–occurs again, refer to the section ‘6.4 fault nding’.
6.4 Fault Finding
If the heater will not operate, disconnect it from the mains and arrange for a certied
electrician to attend and investigate the reason.
