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-red 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 owner’s manual before using the

heater.

• Use only in places free of ammable vapors or high dust

content.

• Never use heater in immediate proximity of ammable

materials (the minimum distance must be 6 ft.).

• Make sure re ghting equipment is readily available.

• Make sure sufcient 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.
