4.20 305 1,50 109 2,8 kpa
This appliance is designed to operate with LPG at nominal pressure: 2,8 kpa. For a correct
gas combustion the required air quantity is 8,4 m3/h.
WARNINGS
-ALWAYS use heater in accordance with instructions. Read the instructions book carefully
and keep it in a safe place.
-This appliance requires a rubber tube and a pressure regulator in accordance with the
law in force. If not supplied check with your gas supplier.
-Use ONLY in a well ventilated area.
-This appliance MUST NOT be used in basements, high rise flats, bathrooms or
bedrooms and in rooms having volume less than 15 m3(30 m3in living rooms).
-This appliance emits the combustion residues in the room in which is used.
-DO NOT place clothes or other materials on the heater, as apart from the danger of fire
their presence could affect the efficient working of the appliance (fig. 1).
-DO NOT move heater from room to room when it is lit (fig. 2).
-DO NOT position heater alongside a wall or near curtains or arm-chairs etc. (fig. 3 - 4).
-ALWAYS face heater towards centre of room. Special care should be taken if the heater is on
a surface where it can move or twist on its wheels or castors if knocked by a child or dog, etc.
-Minimum Clearance : 200 mm from sides,1500 mm from front.
-Be sure installation is complying to local standard.
-The heater you have purchased is fitted with safety devices which come on in the event
of malfunctioning while the appliance is in use. If the pilot light (placed opposite the
burner) accidentally goes out, or if the room is not sufficiently ventilated, the safety devi-
ce will block the gas flow, causing the heater to go off.
Gas leakages
If a leak is suspected, turn off gas at the gas bottle, open the window and air the room. DO
NOT disconnect the pressure regulator. Extinguish all naked lights. Slowly turn the gas on
and brush the connections with soapy water or liquid detergent - a gas leak will form bub-
bles. If a leak is found, turn the gas off and inform your Dealer. DO NOT use the heater
again until it has been inspected by your Dealer.
NEVER USE MATCHES TO FIND LEAKS.

ASSEMBLY
GENERAL SAFETY INSTRUCTIONS - Gas bottle
Gas Bottle with 9 kg of maximum capacity can be installed. Changing of gas bottle must not
be carried out in the presence of a naked flame. Use the gas bottle always in upright posi-
tion.MAKE SURE the black neoprene “O -Ring Seal is in place or the regulator bullnose.
Regularly examine, and if unduly compressed or damaged, replace. Support regulator with one hand
while aligning the regulator bullnose (threaded part) with the threaded gas outlet on cylinder valve.
Screw regulator handwheel ANTICLOCKWISE (LEFT HAND THREAD) into gas outlet. Tighten regula-
tor handwheel as ttight as possible by hand only. DO NOT USE TOOLS OR LEVERS TO TIGHTEN.
When connecting the regulator to the gas cylinder, avoid undue twisting of the flexible hose.
To place the bottle in position, remove the rear panel; than put the bottle in position and
replace the panel.
PLACE teh cylinder in the heater cabinet so that the cylinder valve is facing into the compartment.
Take care to ensure that is positioned in such a way that the flexible hose does not come
into contact with the metal panels of the heater, and avoid twisting of the flexible hose.
OPEN cylinder valve by turning handwheel ANTICLOCKWISE. Now refer to the lighting
instruction on the heater itself. Please read carefully and follow the instructions.
Do not turn the bottle upside down to use completely its content.

Pressure regulators, rubber tubes and clips
CHECK that tubing is completely over the nozzles at each end of
the tubing and that it is held firmly in place by tube clips (See
fig.9).Check the expiry date and state of the rubber tube regularly.
If it is past its expiry date or has been damaged, replace it with
one which complies with the current regulations.
When connecting the pressure regulator to the gas bottle avoid
undue twisting of the flexible tubing.
This heater must be used with an approved Low Pressure Regulator which complies with
SAB S1237. The regulator is required to reduce the pressure of the gas in the cylinder from about
700 kPa to about 2,8 kpa to operate the radiant - the heating panels).
Ventilation
USE ONLY IN A WELL VENTILATED ROOM
Adequate ventilation must be provided in rooms in which the heater is used. This ensures
removal of the products of combustion and allows the entry of replacement air.
The following table shows the smallest size of room suitable for each heat setting and the
dimensions of the aperture which must be provided equally divided between high and low
level, according with the maximum, medium or minimum power.
Safety guard
The guard is to prevent risk of fire and no part of it should be permanently removed.
It does not give full protection for young children or the infirm.
OPERATING INSTRUCTIONS
Lighting the heater
1. Open the gas bottle tap.
2. Fully depress the large knob on the valve for 10 seconds and then turn it 90° to the right
or left to activate the piezoelectric starter (if the pilot flame does not ignite return the
knob to the initial position and repeat the operation). Continue to hold the knob down
for a further 20 seconds to allow the thermocouple to heat up, then release the knob.
Turn the small thermostat knob anticlockwise to position +, to ignite the 3 burners.
When the room has reached the desired temperature, turn the thermostat knob clockwise
until the 2 burners on the left go off. In this way, the appliance will automatically main-
tain the set temperature by cycling between maximum output (3 burners) and minimum
output (1 burner) and vice-versa.
In the event of “burn back” turn off and try again. Should it happen a second time,
return the unit to the dealer.

Auxiliary ignition
Should the piezoelectric starter fail to work, repeat the operation described above, using a
match to light the pilot flame.
Turning off the heater
To turn off the heater, close the gas bottle tap.
The appliance will be completely off only when the gas bottle tap is closed.
Important
When the large knob is released at the end of the ignition time (see the rating plate and
instruction booklet), it must return upwards by around 5 mm to its initial position. If this does
not happen, close the gas tap and contact your after-sales service centre. Never operate the
appliance with the large knob held downwards by force.
Important
DO NOT cover the appliance when in operation, this could cause a dangerous risk of fire.
Important notes
-Use the appliance only standing on the floor.
- The heater must always operate in upright position.
- Never direct the hater air flow towards furniture, curtains , spray cans and inflammable
material.
- Do not install the appliance in a room which might contain gas, oil or sulphur, or near
sources of heat.
- After an extended period when the heater is not in use check the “O”-Ring Seal before
lighting up the heater. Replace the “O” Ring Seal if cracked or broken.
-Do not use the appliance in the mountains at high altitudes.
- DIARISE: During March/April of each year check the “O” Ring Seal.
MAINTENANCE
Wipe your appliance with a soft damp cloth and only when it is switched off, cold and
unplugged. Do not use solvents or abrasives detergents.
Check that there is no dust blocking the air inlet or outlet grids. Clean using a vacuum clea-
ner. When not in use remove plug from socket and store cable. When not in use the heater
should be covered and stored in a dust-free place. Refer any major maintenance to your
Technical Assistance Service. Major servicing should be carried out every 2 - 3 years. If in
doubt refer to your nearest Technical Assistance Service.
