General Recommendations; Safety Devices - widmer FIRE 45 Manual De Instrucciones

Before using the space heater, carefully read all of the instructions and follow them scrupulously.
The manufacturer cannot be held responsible for damage to persons and/or property caused by improper use of
the equipment.
This instruction manual is an integral part of the equipment and must therefore be stored carefully and passed on
with the unit in the event of a change of ownership.

GENERAL RECOMMENDATIONS

The generator described in this manual is a portable oil-fuelled
infrared heat generator.
Its easy handling and large fuel tank allow it to be used locally
and temporarily with complete stand-alone operation.
The area to be heated is therefore hit by an even and uniform
flow of heat, as can be seen by the shape of the irradiation cone
(22), without air movement.
The unit is a direct combustion hot generator that works by
sending both hot air and combustion products in the room you
wish to heat: all the necessary precautions must therefore be
taken to guarantee a sufficient exchange of air.
Always follow local ordinances and codes when using this
heater:
• Follow the instructions in this booklet very carefully;
• Use only in places free of flammable vapours or high dust
content;
• Keep inflammable material at a safe distance from the heater
(minimum 3 metres);
• Make sure fire fighting equipment is readily available;
• Ensure that the machine resting surface or ground is not made
of flammable material;
• 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;
• nothing is obstructing the aspiration and expulsion of air;
movement of air may be obstructed in various ways including
placing covers or other objects on the heater or positioning the
heater too near a wall or other large object;
• 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;
• Unplug heater when not in use.

SAFETY DEVICES

The heater is fit with an electronic device that controls the
flame and the maximum safe temperature by means of a
photocell and an overheat thermostat.
The electronic device controls start/stop times and trips the
safety in case of malfunctions. It has reset button (13) that can
assume different colours (Function Light) depending on the
function mode:
• off: heater is in idle mode or in "stand-by" mode, waiting for
heating request;
• steady green: heater functioning normally;
• steady red: heater in safety stop;
• flashing orange: heating interrupted due to excessive
variations in voltage supply (T<175V or T>265V); heating will
resume automatically when voltage returns in range from 190
V and 250 V.
Warning
To restart heating after a safety stop, push reset
button (13) for 2 seconds.

IMPORTANT
Warning
NEVER do more than two restarts in a row:
uncombusted diesel fuel may accumulate in the
combustion chamber and suddenly flare up at the
next restart.
If the safety stop persists, you have to find and eliminate the
cause of the stop before you restart the heater. Push button (13)
for at least 5 seconds to launch a self-diagnosis programme,
after which the button will assume different colours (Self-
diagnosis light) depending on the type of safety that tripped:
• flashing orange: false flame detected during restart cycle.
• flashing red: no flame during restart cycle.
• flashing red/green: no flame during work cycle.
• steady orange: internal error of electronic device.
Warning
See "TROUBLESHOOTING" to identify the cause of
the malfunction.
OPERATION
Before switching on the heater and, therefore, before plugging
it into the electrical power supply, check that the power supply
specifications are the same as those stated on the identification
plate.
Warning
For models "DV" check that the arrows on the
voltage supply selector key cover are pointing to
the voltage value required.
If necessary:
• remove the cover;
• press deflector (23) to the position required;
• replace the protective cover.
Warning
• The power line must be earthed and fitted with a
• The heater plug must be inserted into a socket
The heater must be placed on a flat, stable, and levelled
surface in order to prevent it from overturning and/or diesel leaks
from the tank filler cap.
The flow of heat can be directed upward with an approximately
10° angle: loosen the two locking knobs (A) and tilt the
combustion unit by pressing on the handle until the desired angle
is reached, then lock the knobs (A) by screwing them.
