Operating Instructions and OwnerÊs Manual

IMPORTANT

Before using the heater, read and understand all instructions and follow them carefully. The manufacturer is not responsible for damages to goods or persons due to improper use of units.

GENERAL RECOMMENDATIONS

The direct-fired heater runs on diesel fuel. This direct combustion heater exhausts hot air and the combustion products into

the room, while those with indirect combustion are fitted with a flue to take the fumes away through the chimney.

Always follow local ordinances and codes when using this heater:

•Read and follow this ownerÊs manual before using the heater.

•Use only in places free of flammable vapors or high dust content.

•Never use heater in immediate proximity of flammable materials (the minimum distance must be 6 ft.).

•Make sure fire fighting equipment is readily available.

•Make sure sufficient fresh outside air is provided according to the heater requirements. Direct combustion heaters should only be used in well vented areas in order to avoid carbon monoxide poisoning.

•Never block air inlet (rear) or air outlet (front).

•In case of very low temperatures add kerosene to the heating oil.

•Make sure heater is always under surveillance and keep children and animals away from it;

•Before starting the heater always check free rotation of ventilator fan.

•Unplug heater when not in use.

•DO NOT USE EXTERNAL FUEL SOURCE.

•DO NOT OPERATE HEATER WHERE FLAMMABLE LIQUIDS OR VAPORS MAY BE PRESENT.

•DO NOT START HEATER WHEN CHAMBER IS HOT

•DO NOT START HEATER WHEN EXCESS FUEL HAS ACCUMULATED IN THE CHAMBER.

•DO NOT PLACE COOKING UTENSILS ON TOP OF THE HEATER.

•PLUG ELECTRICAL CORD INTO A PROPERLY GROUNDED THREE-PRONG RECEPTACLE.

The generator can only work automatically when a control device, such as for example a thermostat or a timer, is connected to the generator. Connection to the generator is made by removing the socket cover(4) and inserting the thermostat plug.

To start the machine you must:

•If connected to the thermostat, turn the switch to (ON + ); •If not connected to the thermostat, turn the switch to (ON).

When unit is started for the first time or is started after the oil tank has been totally emptied, the flow of oil to the burner may be impaired by air in the circuit. In this case the control box will cut out the heater and it might be necessary to renew the starting procedure once or twice by depressing the reset button (1).

Should the heater not start, check that oil tank is full and depress reset button (1).

Should the heater still not work, please refer to chapter „OBSERVED FAULTS, CAUSES AND REMEDIES‰.

STOPPING THE HEATER

Set main switch (3) on „0‰ position or turn thermostat or other control device on lowest setting.

The flame goes out and the fan continues to work for approx. 90sec. cooling the combustion chamber.

SAFETY DEVICES

The unit is fitted with an electronic flame control box. In case of malfunction this box will cut in and stop the heater, at the same time the pilot lamp in the control box reset button (1) will light up.

Heaters are also equipped with an overheat thermostat safety cutout which will stop the heater in case of overheating. This thermostat will reset automatically but you will have to depress button (1) on control box before being able to restart the heater.

TRANSPORT

WARNING

•Before making any attempt to restart heater find and eliminate reason of overheating.

Before heater is moved it must be stopped and unplugged. Before moving the heater wait till it has totally cooled off and make sure oil tank cap is securely fixed.
