1.6 Additional safety
• The maximum static pressure in the duct
system is 10.44 lb/ft
2
.
• The maximum air temperature of the
ducts is 220 °F.
Warning
• Make sure that the convector
heater has cooled off sufficiently
and that the plug has been
removed from the socket before
carrying out any repair or
maintenance work.
Warning
• Connect the heater only to a
1-phase 120 V / 60 Hz power
supply.
• Replace fuses only with identical
spares.
• The heater must be grounded.
Warning
• Use only No.1 fuel, No.2 fuel or
Diesel.
• Do not use gasoline or crankcase
oils.
• Place the separate fuel tank at
least 7 ft from the heater.
• Do not fill the tank while the
heater operates.
• When the static pressure is not
within the limitation of the heater,
this can cause damage to the fan
motor or heat exchanger.

2 INTRODUCTION
2.1 Purpose
The heaters are indirectly fired heaters with
photocell control and connections for a room
thermostat and flue with raincover.
The heaters are tested at sea level and at a
temperature of 68 °F.
2.2 Working principle
An electric motor drives a fan and fuel pump.
The pump draws the fuel from the tank to a
magnetic valve. The fan blows air into and
around the combustion chamber.
The magnetic valve opens 12 seconds after
switching on the heater and the fuel flows into
the nozzle.
A spark between the electrodes ignites the
atomised fuel and starts a flame. The light
from the flame activates a photocell. After the
safety time the ignition switches off. The
magnetic valve closes when you switch off
the heater, or as a result of a fault, the flame
stops.
The fan runs until a thermostat switches the
fan off: the cooling cycle is complete.

• Wheels with tyres (only for ITA 45 and
ITA 75).
3 GETTING STARTED
3.1 Remove packaging
1. Remove the packaging from the heater.
2. Attach the handle and the bumper to the
heater (only for ITA 75).
3.2 Installation
1. Make sure that the heater is placed
horizontally.
2. Fill the tank with fuel.
3. Make sure there is sufficient distance
between the wall and the air inlet.
Minimum distance is 4 ft.
4. Make sure that the heated air can flow
without obstruction. Minimum distance
from outlet to an obstacle is 7 ft.
Caution
Use only No. 1 fuel, No. 2 fuel or
Diesel.
Caution
• Be careful when you fill the tank.
Remove any spilled oil from the
heater and the ground.
• Gas oil tends to thicken at low
temperatures. This can block the
filters. Add a maximum of 15%
paraffin to the fuel at
temperatures below -20 °F, o r
keep the fuel frost-proof, or use
tank heating (optional).

5. Check the ventilation surface area: for
each 3500 BTU a surface of 270 ft
2
is
needed.
6. Check the connection of the room
thermostat.
Do not remove the cap when you do not
use a room thermostat.
Remove the cap to connect a room
thermostat.
7. Install the flue (4 ft and a raincover).
8. Make sure the On/Off switch is in the
0 position.
9. Check the supply voltage: see the
identification plate.
10. Put the plug in the socket.
11. Press the reset switch.
3.3 Power up
1. Press the On/Off switch to switch on the
heater.
2. Set the room thermostat.
The heater supplies warm air after
approximately 10 seconds.
4 OPERATION
4.1 During operation
4.2 Power down
1. Switch off the heater.
The magnet valve closes and stops the
fuel supply.
2. Disconnect the electric power.
Caution
Do not switch on the heater when the
tank is empty!
Caution
The fuel system de-aerates through
the nozzle. Close down may occur
several times when starting with an
empty filter. To rectify: press the reset
switch.
Hot
Do not touch the flue with rain cover,
nor the air outlet! The flue with rain
cover and the air outlet become hot
during operation!
Caution
After you switch off the heater, the
fan still rotates. The fan cools the
heater to avoid damage caused by
overheating. The fan stops
automatically.
Do not remove the plug from the
socket until the heater fully stops!

5 MAINTENANCE
5.1 Maintenance table
After each winter season, record the
maintenance in the table at the back of this
book.
/i
5.2 General
If the heater is not used for a long period:
1. Empty the tank, rinse the tank with
paraffin.
2. Fill the tank with diesel oil, to prevent
corrosion in the tank.
3. Let the heater burn for 3 minutes. This
protects the pump against corrosion.
4. Keep the burner head free from dust and
sediment.
A dirty burner head causes bad
combustion that makes soot and carbon
and damage to the burner chamber.
5.3 Adjustment air inlet and
electrodes (fig. 6)
A Distance nozzle-swivel disc
B Opening air inlet
C Distance nozzle-electrode
D Distance swivel disc-cone
5.4 Electrodes (fig. 7)
Check the electrodes:
1. Remove the cover of the heater.
2. Remove the oil pipe (B).
3. Loosen the electrode cables (A).
Warning
For all service and adjustments
contact qualified, competent and
authorized persons.
