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.
