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.

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 regulator 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 compart-
ment. 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 ligh-
ting 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 regu-
larly. If it is past its expiry date or has been damaged, replace it
with one which complies with the current regulations. Avoid ben-
ding or constricting the rubber tube when the pressure regulator is
connected to the gas cylinder. 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 fol-
lowing table shows the smallest size of room suitable for each heat setting and the dimen-
sions 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.
