GENERAL RECOMMENDATIONS
The hot air heater run on heating oil. Those with direct combustion
send hot air and the combustion products into the room, while those
with indirect combustion are fitted with a flue to take the products of
combustion away through the chimney.
Always follow local ordinances and codes when using this heater:
• Read and follow this owner’s manual before using the heater;
• THE INSTALLATION OF THE UNIT SHALL BE IN ACCORDANCE
WITH THE REGULATIONS OF THE AUTHORITIES HAVING JURIS-
DICTION. Also, as a recommended installation practice reference
should be made to the current issue of CSA B139, Installation
Code for Oil Burning Equipment in Canada and NFPA 31 Standard
for the Installation of Oil-Burning Equipment in the USA;
• Use only in places free of flammable vapours or high dust con-
tent;
• Never use heater in immediate proximity of flammable materials
(the minimum distance must be 2 m);
• Make sure fire fighting equipment is readily available;
• Make sure sufficient fresh outside air is provided according to
the heater requirements. Direct combustion heaters should only
be used in well vented areas in order to avoid carbon monoxide
poisoning;
• A rough estimate of opening required for each gallon (US) of ca-
pacity is one square foot for indirect-fired heater and three
square foot at heater level, for direct-fired heaters;
• the generator is installed near a chimney to take away the fumes
(see the paragraph “FUMES FLUE POSITIONING DIAGRAM”) and
connected to an electrical switchboard;
• Never block air inlet (rear) or air outlet (front);
• In case of very low temperatures add kerosene to the heating oil;
• Make sure heater is always under surveillance and keep children
and animals away from it;
• Before starting the heater always check free rotation of ventilator;
• Unplug heater when not in use.

electrical supply conforms to the data on the model plate.

In heating mode the heater can run automatically when connected
to a control device such as thermostat, time clock. Connection of con-
trol is made to connectors 2 and 3 of the plug (15) fitted to the heater
after having removed the bridge between 2 and 3 as fitted ex works.
This bridge should be kept and retrofitted if manual running of heater is
whished at another time.
When unit is started for the first time or is started after the oil tank
has been totally emptied, the flow of oil to the burner may be impaired
by air in the circuit. In this case the control box will cut out the heater
and it might be necessary to renew the starting procedure once or
twice by depressing the reset button (13).
Should the heater not start, check that oil tank is full and depress
reset button (13).
Should the heater still not work, please refer to chapter “OB-
SERVED FAULTS, CAUSES AND REMEDIES”.
STOPPING THE HEATER
Set main switch (14) on “0” position or turn thermostat or other
control device on lowest setting.
The flame goes out and the fan continues to work for cooling the
combustion chamber.
Warning
Do not unplug power cord until fan motor has completely
stopped
SAFETY DEVICES
The unit is fitted with an electronic flame control box. In case of
malfunction this box will cut in and stop the heater, at the same time
the pilot lamp in the control box reset button (13) will light up.
Heaters are also equipped with an overheat thermostat safety cut
out which will stop the heater in case of overheating. This thermostat
will reset automatically but you will have to depress button (13) on
control box before being able to restart the heater.

life to your heater.
Warning
Never service heater while it is plugged in, operating or
hot.
Severe burns or electrical shock can occur.
