4. OPERATING INSTRUCTIONS3. ASSEMBLING INSTRUCTIONS - CONTINUED
• Position the heater on a at, level, non-ammable & solid surface.
• Indirect-red heaters while used in indoors, must be connected to an exhaust
pipe to vent the fumes of combustion outside. To maintain an adequate Oxygen
rate, a minimum of 80 m3/h airow from outside must occur.
• For indirect-red heaters: connect the heater to an exhaust duct. To get a proper
exhaust ow out, the fumes must rise throigh the ue. Avoid any elbows and
bends in the rst part of the exhaust ducts for at least 3m.
• Only position the heater in the normal upright position (on the wheels)
• Do not place the heater near walls, corners or low ceilings.
• Do not place the heater below a power socket outlet.
• Do not place the heater on moving vehicles or where it can tip over.
• Keep the heater away from ammable, combustible, explosive or corrosive
materials.
• Keep the heater away from curtains or similar materials that could block the air
inlet and outlet.
• Never block or restrict the air inlet and outlet for any reason.
• Keep the power cable away from heat sources, sharp edges, cutting and
moving parts.
• Do not expose directly to the weather or to excessive humidity.
• Do not place the heater in the immediate surroundings of a bath, shower or
swimming pool.
• Ensure the following minimum safety clearances from materials or objects in the
surroundings of the heater:
Side: 0.6m
Air inlet side: 1m
Top: 1.5m
Hot air outlet side: 3m

FLUE/EXHAUST INSTALLATION
For indirect-red heaters: connect the heater to an exhaust duct. To get a proper
exhaust ow out, the fumes must rise throigh the ue. Avoid any elbows and bends in
the rst part of the exhaust ducts for at least 3m.

4. OPERATING INSTRUCTIONS - CONTINUED4. OPERATING INSTRUCTIONS - CONTINUED
START-UP
• Fill the tank with clean fuel. Only use Diesel or Kerosene
• The fuel gauge on top of the tank allows you to check the fuel level
• Connect the plug to the relevant power source
• The left display will show “- -”, the right display will show the ambient temperature.
• Push the power switch to “ON”.
• The default temperature setting is 20’C (left display)
• If the ambient temperature is lower than the default temperature, the electrodes
will start sparking & after 7 seconds the heater will start.
• If the ambient temperature is higher than the default temperature, turn the
thermostat control knows to desired temperature. the electrodes will start
sparking & after 7 seconds the heater will start.
COLD START-UP
In low temperature, in Alpine/Highland/Inland regions, unseasonably cold weather.
Block the air vent hole on the air pump (see Fig. 4) by using your nger during ignition
to make start-up easier.
ABNORMAL OPERATION:
In case of malfunction (ame failure, reduced air ow, bad combustion) the heater
stops and the indicator light starts FLASHING (THE LOCK-OUT MODE code will be
showed on the display window).
MANUAL RESET/RESTART
If the heater is in lock-out mode, check and remove the cause of lock-out before
restarting the heater. To reset, turn the ON/OFF switch to 0 and then again to I. If
problem continues please contact Fanmater. Turning the thermostat control knob will
NOT reset the heater.
SHUTDOWN
Move switch to “OFF” (O) position.
• Never disconnect the heater from mains to stop it while in operation.
• Always allow the cooling sequence to be completed, otherwise the residual heat
could damage internal components.
• Do not cover the heater. Do not block the air inlet and outlet.
• The heater outlet is very hot during operation and after use. Do not touch! Use
personal protecting equipment if needed.
• Unplug the heater before moving it. Never pull the cable to unplug or move the
unit.

5. CLEANING, MAINTENANCE & STORAGE
• Before starting any maintenance task, shut down, unplug and let the heater cool
down for at least 15 minutes.
• Do not attempt any electrical repair yourself. If the heater needs service or repair,
contact a qualied persons.
• When cleaning, make sure that water does not enter the unit.
• Do not open the enclosure to clean the inner parts. Do not spray water into the
heater.
• Never use solvents, gasoline, toluene and similar aggressive chemicals to clean
the heater.
Regularly wipe the enclosure using a soft sponge or cloth. For very dirty parts, use a
sponge wetted with lukewarm water and a mild detergent, then dry using a clean
cloth. Keep air inlet and fan free from dust and dirt. To clean inner parts, gently blow
compressed air through air inlet. Regularly inspect the power cable: if worn, cracked
or damaged have it replaced by a qualied persons only.
Before storing the heater, make sure it is perfectly cool and dry. Cover the unit with a
blanket or tarp and store it in a dry, ventilated plac
The following checks are recommended before every seasonal use:
Nozzle
Carefully unscrew nozzle from nozzle tting. Blow compressed air through nozzle
orice to free it from dirt. Replace nozzle if necessary.
Fuel Filters
Clean fuel lters by unscrewing the lter tray (clockwise) Remove the lter cartridge
and wash it with petrol or replace it if necessary. Check seal O-ring and replace it
if necessary. Reassemble the tray (Fig.2). The fuel lter installed on the gear pump
should be cleaned or replaced if necessary by unscrewing cap H (see Fig. 4)
Fig 2.
Whirl disc (extract the burner head)
Clean the whirl disc (Fig.3) using a brush and then
blow compressed air on it. To get good combustion
the air ow openings in the whirl disc should be
perfectly clean and free.
Fig 3.
Ignition Electrodes (qualied peron only)
Clean, adjust, & if necessary replace
ignition electrode. For electrode gaps see
Fig.5-6 (dimensions in mm)
Fig 5. Fig 6.

5. CLEANING, MAINTENANCE & STORAGE - CON5. CLEANING, MAINTENANCE & STORAGE
Fuel Pump Pressure Adjustment (Fig 4.)
The Fuel pump pressure is factory set and must be checked and adjusted by
qualied technicians only. Tampering with the unit may be dangerous.
Remove pressure gauge cap (P). Connect a pressure gauge on the pressure
measuring port on pump. Start heater and read fuel pressure value. If necessary
adjust pressure to the correct value turning the adjusting screw (P1) clockwise to
increase, anticlockwise to decrease the pressure:
HIGH ALTITUDE ISTALLATION
Due to lower oxygen rate with reference to high altitude installation on sea level, it
may be necessary to increase air rate by opening the air collar (Fig. 8), or to reduce
the setting pressure on fuel pump (Fig. 7). This setting adjustment can be necessary to
prevent excessive smoke emission due to lack of Oxygen.
