ANALYSIS OF COMBUSTION WASTE PRODUCTS
The probes which check the composition of combustion waste prod-
ucts 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. The gas used to predispose the heater at factory has been
declared on data plates applied on the box and on the heater itself
(methane, G20, or L.P.G., G30, G31).
To change from methane gas to L.P.G. or vice-versa you must:
• Adjustments to be carried out are described in the burner instruc-
tions manual.
• Repeat regulation of combustion while composition of combustion
waste products are checked.
• Correct data plate on the heater writing which type of gas must
be used.
REGULATION OF COMBUSTION - I° OPERATION
After having checked the hermetic seal and of combustion waste
products line, heater may be operated for the first time. To perform
regulation of combustion correctly, combustion waste products must
be analysed using appropriate instruments: values recommended by
actual standards must be reached.
The regulation procedure has been on the Burner Instruction Manual;
final values of CO2 shall be correspondent to excess air factor of 1,2
(12,5 for gas-oil, 9,7% for G20, 9,6% for G25, 11,7% for G30 and
11,7% for G31) while CO level shall be less than 75 ppm.
04. 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
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 op-
erations consult the Troubleshooting section of this manual.

TURNING OFF
In manual operation turn control knob (2) to "0" or turn off control
Fig.3. in automatic operation. The burner stops while the fan turns itself on
and off until the combustion chamber has completely cooled down.
m Never stop the heater by simply turning off the discon-
necting switch on the electric switchboard. The electrical
supply must only be disconnected when the fan has come
to a complete stop.
VENTILATION
When the control knob is turned to the symbol
ates in continuous fan mode.

05. Maintenance

Preventive and regular maintenance will ensure a long trouble free
life to your heater.
m The following operations must be carried out by qualified
personnel only. Before carrying out any maintenance op-
eration the heater must be disconnected from the mains.
Therefore:
• Stop the machine as instructed above.
• Turn off the disconnecting switch on the electric switch
board.
• Wait until the heater has cooled.
CLEANING THE HEAT EXCHANGER AND THE COMBUSTION CHAMBER
For the heater to operate efficiently the heat exchanger and com-
bustion 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 incorrectly or when the heater
is switched on and off too frequently. If the heater starts vibrating
when it is turned on there is probably too much soot.
To get at the heat exchanger (1) take off the front panel (3) and then
remove the smoke box panel (2) and remove baffle plates (7). To get
at the combustion chamber (4) remove the burner (5).
