OPERATING INSTRUCTIONS

Warning
Any time the power cord of the heaters is connected
to a receptacle check the polarity of power supply:
• Check switch (9) and (13) are on "0" (REFER to FIG. 5)
• Connect plug to receptacle
• If lamp (#14 FIG. 5) lights up, then reverse polarity
Warning
If the correspondence of phase / neutral polarity is
not correct, the unit may stop in the reset mode.

HEATING MODE

Turning ON:
• Make sure switch (#9 FIG. 5) is on "0";
• Power the heater by means of the sectioning switch on
the switchboard;
• If the unit is operated manually (without any thermostat
or any other control device) turn the switch (9) to posi-
tion "1". The burner starts up, the combustion chamber
heats up and then the fan starts;
• If the unit operates automatically (being connected to
any thermostat or any other control device) turn the
switch (9) to position "1" and set the room thermostat
at the desired level: the heater will now start and stop
automatically.
• If after these operations, the generator does not work,
refer to the "FAULTS, CAUSES AND REMEDIES" para-
graph and find the cause.
SETTING POST VENTILATION MODE:
By the switch (#13 FIG. 5) on control panel, select the
post-ventilation mode, that is the time the fan goes on
blowing air when unit is switched off:
• When switch (#13 FIG. 5) is on pos. "0" then post venti-
lation lasts for 30 sec.
• When switch (#13 FIG. 5) is on pos. "1" then post venti-
lation is continuous.
Turning OFF:
In manual operation turn switch (#9 FIG. 5) to "0" or turn
thermostat control knob off.
After switching off the machine, a post ventilation func-
tion works according to the previous setting.
Warning
Finally, close the gas supply on/off valve, close the
shut-off valve (f) and turn off the sectioning switch
(Fig. 5).

VENTILATION MODE

To obtain the ventilation function only, make sure switch (#9
FIG. 5) is on position "0" and then simply turn the switch
Forced-Air Agricultural Construction Heater
(#13 FIG. 5) to position "1". To stop it, turn the switch to
position "O".
Warning
Whichever the reason, the unit only tries to restart
once. If the cause of malfunction remain, the unit
definitively stop and lamp (8# FIG. 5) will light up.
The heater can be restarted only by pressing the reset
button (#8 FIG. 5). Nonetheless, the cause that triggered
the safety device should always be carefully analyzed and
resolved before restarting the generator (cfr."FAULTS,
CAUSES AND REMEDIES").
TRANSPORT AND HANDLING:
Warning
Before moving the unit:
• Stop the machine as indicated in the "STOP"
paragraph;
• Disengage the power supply by removing the plug
from the power socket;
• Fully unscrew the fitting connecting the gas hose
pipe to the heater;
• Wait for the heater to cool down.

Fuel Conversion

Warning:
The conversion shall be carried out by a
manufacturer's authorized representative,
in accordance with the requirements of the
manufacturer, provincial or territorial authorities
having jurisdiction and in accordance with the
requirements of the can/cga-b149.1 Or can/cgab149.2
Installation codes.
A conversion label shall be applied adjacent to the Rating
Label:
THIS APPLIANCE HAS BEEN CONVERTED FOR USE
AT AN ALTITUDE OF ___________ FEET (ABOVE 2000 FEET)
Orifice size: ______________________________________
Manifold pressure: ______________________________________
Input rate: ______________________________________
Date of conversion: ______________________________________
Type of fuel: ______________________________________
Converted by: ______________________________________
This operation may be carried out several times during the
working life of the heater and not only at initial start-up.
First of all refer to SPECIFICATIONS to identify the
reference category for natural gas or propane gas type.
For each gas category the supply pressure, the working
pressure and the arrangement of the diffusion ring (#3
FIG. 4) are stated.
To convert from one type of gas to another proceed as
follows:
•If stated in Tab.I, change the diffusion ring (#3 Fig. 4):
•Remove the upper body of the heater;
•Unscrew and remove the ionization electrode (#6 FIG. 4)
