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.
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. Fig 1 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.
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.
• 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 ‘lockout’, 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.
TROUBLESHOOTING PROBLEM CAUSE SOLUTION Heater fails to start when the switch is set to ON. No electrical supply. Check mains, switch and fuses. Defective on/off switch Request your service technician to replace on/off switch. Heater starts but malfuctions almost immediately. Burner Lock-Out. Reset burner. If lock-out repeats, reset after 4-5 minutes. Defective motor/ capacitor. Request your service technician to check motor/capacitor & replace if necessary. No fuel in tank. Air in the fuel line.
TROUBLESHOOTING PROBLEM CAUSE SOLUTION Orange LED remains on and burner will not start. Heater and start thermostat are faulty. Request your service technician to replace defective item. Green LED is on and the burner remains in the pre-purge phase. The photoelectric sensor sees a false light. Eliminate the daylight. Burner runs normally in the pre-purge and ignition cycle but locks out after approx 5 seconds. The photo-resistance is dirty or defective.
CLEANING AND MAINTENANCE WARNING: ALWAYS ENSURE THE HEATER HAS COOLED DOWN BEFORE PERFORMING ANY MAINTENANCE TASKS Before carrying out any adjustment or maintenance, ensure the heater is switched OFF, disconnected from the mains supply, and has been given adequate time to cool down. CLEANING 1. Use a damp cloth wrung out in a solution of soapy water to clean the exterior of the heater. Use household cleaners on difficult spots. 2.
