OVERVIEW OF THE IRD40 HEATER
The IRD40 Infrared Diesel Heater is ideal for the following applications:
• Heating work areas in large, well ventilated rooms or outbuildings.
• Dust-free drying of components.
• Drying out and de-icing of construction areas, concrete, walls etc
• Defrosting large machines and buildings.
FUNCTIONAL DESCRIPTION
A pump draws fuel from the tank and drives it to the burner under pressure.
Fuel is sprayed and atomised by the nozzle and then ignited by the burner
ignition device. A built-in radial blower provides combustion airflow while air
and fuel forms a combustion mixture. The flames heat up the front plate and
guard, thus releasing heat by radiation.
The metal front guard acts as a catalyser, completing the combustion of
hydrocarbons and reducing emission pollution. The unit can be tilted at up to
20O upwards or downwards to direct heat at a particular target. The burner
pre-heater warms up the fuel before start-up and the post-ventilation
function cools down the chamber after each use. No flue or exhaust pipe is
required as all combustion gasses are catalysed during operation.

PREPARATION
When unpacking, check the heater
for any damage that may have
occurred in transit and notify your
Clarke dealer immediately should
any be apparent.
Fill the tank with clean, water-free
diesel oil. When refilling, inspect the
mesh filter inside the filler neck for any
trapped contamination.
Note: The burner has been designed
for use with diesel fuel oil having a
maximum viscosity of 35 seconds Redwood No1 at 100OF.
Plug the heater into any suitably earthed mains power supply.
POSITIONING THE HEATER
The heater must be located on a
hard, level surface to minimise the risk
of accidental tipping or running
forward. Chock the wheels if there is
any possibility of movement.
Set the heater in position by loosening
and re-tightening the positioning
clamps on either side to achieve the
required angle of tilt.
MATERIAL CLEARANCES
It is important that the heater be positioned with at least 3 m clearance at the
front between the heater and any obstruction including walls or other
combustible surfaces. Always position the heater facing the centre of the
room. Never place any objects on, or against the heater.
Any equipment or workshop furniture should be a safe distance away as they
could be adversely affected by heat.
VENTILATION
The heater must only be installed in a room which is well ventilated. Ensure
that sufficient air is available for combustion via windows and doors,
especially if there will be people staying in the room for any length of time.
Constant occupation is not advised although the heater should be monitored
periodically.
• Ventilation is essential to reduce the dangers of oxygen depletion.

HEATER OPERATION WITHOUT PEOPLE IN THE ROOM
Ensure that sufficient air is available via windows and doors for complete
combustion. The heated volume (m3)/ heat output (kW) ratio must be at least
10:1, and personnel should not stay permanently in the heated room.
HEATER OPERATION WITH PEOPLE REMAINING IN THE ROOM
If people are to remain in the room for any length of time, the heated volume
(m3) /heat output (kW) must be at least 30:1. Air circulation must be ensured
through windows and doors or permanent openings near the floor and
ceilings, whose total open area (m2) is at least 0.003 times the total heat
output (kW).
OPERATION
In normal operation, operating the ON/OFF switch will illuminate the red LED
and the green and orange warning lights. After two minutes, when the fuel
warming operation is completed, the orange warning light and the red LED
go out and the motor starts.
The following table shows the main operating phases.
LIGHTING THE HEATER / START-UP
To start the heater;
1. Check that there is diesel in the fuel tank.
2. Switch the ON/OFF switch to ON.
• The green and orange LEDs will light up for the duration of the pre-heating
time.
• Ignition does not take place immediately but after a pre-heating time
followed by a ‘pre-purge’ time of about 30 seconds.

• If no fuel flows to the burner within
4 seconds, the heater
automatically goes into ‘lockout’
mode. In this case, check and
eliminate possible causes of ‘lock-
out’, referring to
TROUBLESHOOTING, then press the
RESET button to restart the heater.
If the heater does not start, check it is
not directly aimed towards a bright
light, which could interfere with the
operation of the burner control photocell.
POSSIBLE FAULTS ON STARTUP
A technical fault on start-up usually makes the “Lock-out’ lamp illuminate. This
is built into the reset button on the front of the control box as shown in Fig 3.
When this happens, the controls of the burner are at ‘lock-out’. The burner
can only be lit after pushing the reset button and if, after this, the burner
operates correctly, the lock-out can be attributed to a temporary fault such
as a fluctuation in voltage.
If the lock-out continues, the cause must be determined & a solution found.
Request a qualified heater service technician to investigate the problem.
Refer to the following tables for a list of possible faults and their cause.
TURNING THE HEATER OFF
1. To stop, set the ON/OFF switch to off.
• The fan will continue running for a pre-set time while the heater cools
down.
WARNING; NEVER SWITCH OFF THE HEATER BY DISCONNECTING IT
FROM THE POWER SUPPLY.
