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 owner’s 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.
