DRAFT
The evacuation smoke flues have to be in steel and of conforming
to the norm EN 1443.
Efficient combustion and trouble-free working of the burner de-
pend on efficient flue draft. The unit must be connected to the chimney
flue in accordance with current legal regulations and in line with the fol-
lowing guidelines:
• the tube which carries the smoke should cover as short a distan-
ce as possible and should slant upwards;
• there should be no sharp bends in the tubes and the diameter of
the tubes must never be reduced;
• every heater must have its own chimney;
• flue draft must at least correspond to the minimum compulsory
level in the Technical Specifications.
ANALYSIS OF COMBUSTION WASTE PRODUCTS
The probes which check the composition of combustion waste
products and smoke temperature must be positioned as indicated in
Fig. 3.
When these tests have been completed the hole which was drilled
for the probe must be sealed with a material which is resistant to high
temperatures and which ensures that the tube remains airtight.
CONNECTION TO FUEL SUPPLY AND CHANGING FROM ONE TYPE OF
GAS TO ANOTHER
To connect the burner to the fuel supply follow the instructions in
the Burner Instruction Manual.
The burner can use both methane gas and L.P.G. This heater has
been predisposed to use methane gas, G20. To change from methane
gas to L.P.G. or vice versa consult the Burner Instruction Manual which
accompanies this manual. With the Burner Instruction Manual there is
an envelope which contains a spare choke and an adhesive label which
indicates the type of gas that the burner should use.
INSTRUCTIONS FOR USE
Switching on
• set the control knob (2) in position "0".
• turn on the disconnecting switch on the electric switchboard.
• If the unit is operated manually turn the control knob to . The
burner starts up, the combustion chamber heats up and then the
fan starts.
• if the unit operates automatically set the room thermostat at the
desired level and turn the control knob (2) to
now start and stop automatically.
• if the heater doesn't start after you have completed the above
operations consult the Troubleshooting section of this manual.
TURNING OFF
In manual operation turn control knob (2) to "0" or turn off control
in automatic operation.
The burner stops while the fan turns itself on and off until the com-
bustion chamber has completely cooled down.
Warning
Never stop the heater by simply turning off the discon-
necting switch on the electric switchboard. The electri-
cal supply must only be disconnected when the fan has
come to a complete stop.
VENTILATION
When the control knob is turned to the symbol
rates in continuous fan mode.

MAINTENANCE
Warning
The following operations must be carried out by qualified
personnel only.
Warning
Before carrying out any maintenance operation the hea-
ter must be disconnected from the mains. Therefore:
• stop the machine as instructed above;
• turn off the disconnecting switch on the electric swit-
chboard;
• wait until the heater has cooled.
CLEANING THE HEAT EXCHANGER AND THE COMBUSTION CHAMBER
For the heater to operate efficiently the heat exchanger and combu-
stion chamber must be cleaned after a period of prolonged use and
more frequently if too much soot builds up. Soot builds up when there
is not enough chimney draft, when the fuel is of very poor quality,
when the burner is regulated incorrrectly or when the heater is swit-
ched on and off too frequently. If the heater starts vibrating when it is
turned on there is probably too much soot.
To reach the internal part of the heat exchanger and the combustion
chamber remove the burner (a) and the back lower panel (c) as well as
the exchanger inspection panel (e) and the baffle plates (d): Remove
soot and extraneous material with a vacuum cleaner or tube cleaner.

CLEANING THE FAN
Remove any dirt or extraneous material from the mesh of the aspira-
tion grill (f) and if necessary clean the propeller with an air-suction tool.
CLEANING THE BURNER
For the heater to work efficiently the burner must be serviced regu-
larly by an Authorized Service Technician. All cleaning,servicing and re-
gulation operations must be carried out as indicated in the Burner In-
struction Manual.
Warning
After every type of technical maintenance, please verify
that the machine starting regularly.
TRANSPORTING AND MOVING THE HEATER
To move or transport the heater,it place it on a raised base and lift
with by a forklift truck. There are no eyebolts or hooking points for lifting.
The unit can be attached to brackets by attaching the side of the
unit not shown in Fig. 1 (G) to the brackets.
Warning
Before moving the unit:
• turn it off as indicated above;
• disconnect electricity by pulling out the plug;
• wait until the heater cools down.
Never try to lift the heater manually.Doing so could re-
sult in physical injury.
