This appliance is designed to operate with Butane at nominal pressure: 28 ÷ 30 mbar. For
a regular 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 15m3(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.
-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 device will block the gas flow, causing the heater to go off.
-Do not use the heater at high altitudes.
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 15 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 position. If a screw on regulator is used ensure that the
regulator washer is present and in good condition -replace if in any doubt.
To place the bottle in position, remove the rear panel which faces the inside during tran-
sport, by unfastening the screws; than put the bottle in position and replace the panel.
Important
Dear client:
when using the radiant heater as a portable appliance, before filling the gas bottle, remember to
discarge the compressed air that may be contained in it.
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.5). Examine flexible tubing regularly and
get your Dealer to fit new tubing 400 mm
long complying to local standard, if peri-
shed, worn or damaged. Ensure that the rub-
ber tube inserted in the plastic support (see fig. 6). When connecting
the pressure regulator to the gas bottle avoid undue twisting of the flexi-
ble tubing. A 28 ÷ 30 mbar (11.2 in w.g.) pressure regulator for
Butane or Propane complying to local standard must be connected to
the appliance with the above tubing, using suitable tube clips.
Room ventilation
USE ONLY IN A WELL VENTI-
LATED ROOM
Adequate ventilation must be provi-
ded 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 smal-
lest size of room suitable for each
heat setting and the dimensions of
the aperture which must be provi-
ded equally divided between high
and low level.
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 MODEL IH-IHF
Lighting the heater
1. Turn on the gas at the gas bottle tap.
2. FROM « ● » POSITION, fully depress the control knob for 10 seconds and turn to
(Small Flame) position. (If pilot flame does not ignite return to starting position and
repeat). Continue to fully depress the knob for a further 20 seconds to allow the thermo-
couple probe to heat up. Then turn the knob to select the desired setting as follows:
(Small Flame) Low Input (Medium Flame) Medium Input,
(Big Flame) Maximum Input
Auxiliary ignition
Should piezoelectric starter fail to work, repeat operation on control knob and use a match
to light pilot flame and repeat the operations above described.
Turning off the heater
Turn off the gas bottle tap.
The Heater will be totally “OFF” only if the tap at the gas bottle is turned off.
OPERATING INSTRUCTIONS MODEL IH2-IHF2
Lighting the heater
1. Turn on the gas at the gas bottle tap.
2. Depress the button for 10 seconds, consequently depress button two or three times
(If pilot flame does not ignite return to starting position and repeat). Continue to fully
depress button for a further 20 seconds to allow the thermocouple probe to heat
up then release. To light up the 3 burners, turn the thermostat fully counter-clocwise to the
max. (pos .6). When the room temperature has reached the desired level, turn the ther-
mostat clock-wise until the side burners light off. The thermostat will now automatically
maintain the temperature at the desired level changing between max. power (all the
three burners are on) and min. power (only one burner is on).
Auxiliary ignition
Should piezoelectric starter fail to work, repeat operation on control knob and use a match
to light pilot flame and repeat the operations above described.
Turning off the heater
To turn the heater off, turn the thermostat to “●“ position, then turn off the gas bot-
tle tap.
The heater will be totally “OFF” only if the tap at the gas bottle is turned off.
Important
When the operating button” “ is left at the end of the starting time (see also rating plate),
this must move up about 5 mm and return to his starting height. If this does not happen, shut
the gas valve and contact your aftersales service centre. Do not let the appliance work with
the operating knob pressed downwards by force.

VENTILATED RADIANT HEATER
Electrical connection
- Before using the appliance check that your supply voltage is the same as that shown on
the rating label of the unit.
- Connect your heater to earth provided socket only, having a capacity of at least 10/16 A.
- THIS APPLIANCE COMPLIES WITH THE EEC DIRECTIVE 89/336 CONCERNING
ELECTROMAGNETIC COMPATIBILITY.
Operation and use
Fully insert plug into socket-outlet and switch on the fan heater following the instructions
of Fig. 7.
Before switching on the gas burner, read carefully the relevant operating instructions.
IMPORTANT
DO NOT cover the appliance when in operation, this could cause a dangerous rise of the
temperature of the fan heater with consequent risk of fire.
Important notes
-Your heater must always be earthed: warranty does not cover damages caused by non-
observance of this warning.
-Do not use your heater close to wash-basin, bath- tub, shower, swimming pool.
- Do not lay the cable on the hot unit.
-Use the appliance only standing on the floor.
- The heater must always operate in upright position.
-Do not cover either the hot air output or input grid on the top of the unit during service.

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 cleaner. When not
in use remove plug from socket and store cable as
shown in Fig. 8. When not in use the heater should be
covered and stored in a dust-free place. Refer any
major maintenance to your Local Authorised Dealer.
Major servicing should be carried out every 2 - 3 years.
If in doubt refer to your nearest authorised dealer.
Fig. 8
-Replacement of the power cable must be carried out by qualified personnel. Always use
original spare parts supplied by the manufacturer.
-The heater must not be located immediately below a fixed socket outlet.
- A safety device switches the fan heater off if it accidentally overheats.
To reset the unit for normal operation, remove the plug from the mains
socket for a few minutes, eliminate the cause of the overheating (e.g. air
intake or outlet grilles obstructed) and then plug the fan heater back in
again. Contact your nearest Technical Assistance Service if the fan heater
does not start operating normally again.
.- Ñever direct the fan hater’s air flow towards furniture, curtains , spray cans and inflam-
mable material.
