5. Installation Instructions
Position the heater on a flat, level, non-flammable, solid surface.
The exhaust gases are very harmful for people and animals when released in a closed
space without ventilation.
Indirect-fired heaters while used in indoor installation, must be connected to an exhaust
pipe to vent the products of combustion outside. To maintain an adequate Oxygen rate, a
minimum of 80 m3/h airflow from outside must be ensured.
Direct-fired heaters are intended for use in outdoor open areas or in indoor well
ventilated areas. For indoor use, provide permanent ventilation openings of at least 25
cm²/kW, equally distributed between floor and high level, with a minimum of 250 cm².
BGO-100A-16-F
Minimum Opening Size
2500 cm²
•Only install the heater in normal upright position.
•Do not place the heater near walls, corners or low ceilings.
•Do not place the heater below a socket outlet.
•Do not place the heater on moving vehicles or where it can tip over.
•Keep the heater away from flammable, 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.
•Follow general and special fire safety regulations in force in all fields of applications. In
any case ensure the following minimum safety clearances from materials or objects in
the surroundings of the heater:
•Side: 1 m
•Air inlet side: 1 m
•Top: 1.5 m
•Hot air outlet side: 3 m
•Floor: 0 m
•Floors and ceilings must be made of fireproof materials in the place where the heater is
operated.
•Do not connect direct-fired heaters to air ducts.
6. Instructions for Use
M1.0.WD340.EN

6.1. Start-up
Fill tank with clean fuel. Only use Diesel or Kerosene.
The fuel gauge on top of the tank allows to check fuel level
Connect the power cord plug to a AC220V-240V 50 Hz earthed electrical supply system.
Earthing ismandatory.
Models WD340:
When complete “start-up” above,the left display window shows “--”, the right display window shows
ambient temperature value.
Push the power switch to “on” position.
The default temperature setting is 20℃, be showed on the left display window.
If the ambient temperature is lower than default temperature, after waiting for 12 seconds per-
ventilation, the heater starts.
If the ambient temperature is higher than default temperature, turn thermostat control knob to desired
temperature, after waiting for 7 seconds pre-ventilation, the heater starts.
ABNORMAL OPERATION: in case of malfunction (flame failure, reduced air flow, bad combustion,
etc.) the heater stops, the LOCK-OUT MODE code will be showed on the display window-see
troubleshooting.
6.2. 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 (afters 30 sec) again to I. In case of repeated
malfunction, call technical service. Turning the thermostat control knob will NOT reset the heater.
6.3. Shut-down
Move switch to "OFF" (O) position. The post-ventilation phase will cool down the combustion chamber
for 90 seconds. Unplug the unit when not used for a long time.
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.
Children should be supervised to ensure that they do not play with the appliance.
The appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge.
Unplug the heater before moving it. Never pull the cable to unplug or move the unit.
Do not leave the heater unattended when in use.
Never use the appliance with wet hands or when either the heater or the power cable is
wet.
If the supply cable is damaged, it must be replaced by the manufacturer, by a service
agent or a similar qualified person.
7. Cleaning, Maintenance and Storage
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 technical service.
M1.0.WD340.EN

Before storing the heater, make sure it is perfectly cool and dry. Cover the unit with a plastic bag, put it
in its packing box and store it in a dry, ventilated place.
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 qualified technician.
Do not use a faulty unit unless a qualified technician has inspected and repaired it.
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.
The following checks BY QUALIFIED PERSONNEL ONLY are recommended before every
seasonal use:
Fuel Filters
Clean fuel filters by unscrewing the filter tray (clockwise) Remove the filter 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 filter installed on the gear pump should be cleaned or replaced if necessary by
unscrewing cap H (see Fig. 6)
Fig. 2
Extract the burner head（Fig.3）
Fig.3
Whirl disc
Clean the whirl disc (Fig.3) using a brush and then blow compressed air on it. To get good
combustion the air flow openings in the whirl disc should be perfectly clean and free.
Nozzle
Filter tray
M1.0.WD340.EN

Carefully unscrew nozzle from nozzle fitting. Blow compressed air through nozzle orifice to free it from
dirt. Replace nozzle if necessary.
Ignition Electrodes
Clean, adjust and if necessary replace ignition electrode. For electrode gaps see Fig. 4-5 (dimensions
in mm).
Fig.4
Fig.5
Fuel pump pressure adjustment (Fig. 6)
The fuel pressure is factory set and must be checked and adjusted by qualified
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:
Fig.6
Air collar adjustment (Fig. 7)
The air collar position is factory set and must be checked and adjusted by qualified technicians
only. Tampering with the unit may be dangerous.
Pump Pressure (bar)
9.5
10.0
M1.0.WD340.EN

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. 7), or to reduce the setting
pressure on fuel pump (Fig. 6). This setting adjustment
can be necessary to prevent excessive smoke
emission due to lack of Oxygen.
