INSTALLATION
This appliance is designed for use with LPG ONLY. When this
appliance is to be permanently installed the installation should
only be carried out by a qualied gas tter who is registered with
LPGSASA and that such installations should comply with the
requirements of SANS 10087-1 or SANS 827 as applicable.
• Good room ventilation is vital for the efcient performance
of the appliance and for the safety of the occupants in the
room in which the appliance is installed.
• Cooking appliances generate considerable heat. The layout
and materials of the surrounding cabinets should take
account of these characteristics.
• Surfaces of cabinets immediately adjacent to the hob should
be able to withstand temperature of up to 100°C without
delaminating or discolouring.
• Make sure that the unit is well levelled in relation to the
ground. Improper levelling can affect the function of the
appliance.
• Ensure no items which can catch alight easily (eg. curtains)
are near the gas hob.
• Allow an unrestricted air space of at least 150mm at the
sides and 750mm above the hob.

5 BURNER HOB Note: This appliance is
designed for use with
a 2.8 kPa SANS 1237
regulator with SANS
1156-2 approved hose.
Using any other type
of regulator or hose is
extremely dangerous.
Regulator and hose
sold separately.

6
After installation the space under the hob must be at least 30mm.
The distance between the hob and the wall must be at least 35mm.
If an extractor hood is to be used the distance between the top of
the gas hob and the bottom of the hood must be at least 650mm.
LPG (Liquid Petroleum Gas) installation
• Soak the end of the gas-supply hose in hot water to soften it.
• Then push the hose end fully over the gas-supply nozzle located
at the rear of the hob (see picture below).
• Secure the hose by tightening the hose clamp (see sketch below)
• Similarly, secure the other end of the hose to the regulator on the
gas bottle.
If this appliance is not being installed in a built-in structure, there
should be an insulation layer between the appliances bottom and
other components
Before placing the hob in the counter cut out, the supplied foam
sealing strip must be attached to the underneath of the lip of the
hob. This prevents dirt and moisture from the counter top seeping
under the hob.

NOTE: After installing and connecting the hose to the hob and
regulator, and the regulator to the gas cylinder, a gas leak test must
be performed as detailed on page of the booklet.
PERMANENT INSTALLATION
The Gas Fitter must provide you with a written certicate after com-
pletion of the work. Failure to comply with the above will render
the warranty invalid. Before the installer hands over the installed
appliance be sure that you fully understand:
1. The position of the isolation or shut-off valve in the gas supply
line to the hob.
2. The requirements for safe operation of the hob.
GAS:
(1) This appliance is designed for use only with LP gas
(2) Important:
Check for any leakage in your cylinder or connecting hose by
using soapy water around all connections. If a exible hose is
being used, it should be of minimum length to avoid bending.
Periodic checks are recommended for your own safety.
(3) Replace a Jet:
Remove the burner cap as well as the aluminium cap. Use a suit-
able tool to replace the jet (as indicated in picture below).

LEAK TEST
The leak test must be carried out in a well-ventilated area, free
from any ames or other sources of ignition.
• With the cylinder connected
to the hob, open the cylinder
valve.
• Brush the connections (hob
to cylinder) with a solution of
equal parts soap and water
(make sure it’s foamy).
• A stream of bubbles forming
indicates a gas leak. (See
picture on left)
• If bubbles appear, turn the
cylinder valve OFF (clockwise)
and disconnect the hob from
the gas cylinder.
• Tighten the connection and
retry the leak test.
• If you are unsure or if you
cannot tighten the connection,
place the cylinder outside in a
cool, well-ventilated area and
contact Alva on 086 100 ALVA
(2582).
• A leak between the hob and
cylinder can lead to a high
pressure re, which is very
dangerous and can result in
extensive injury or even death.
PRECAUTIONS
Leak test all
connections after each
tank rell
NEVER check for
leaks with a match or
open ame
Any LP Gas cylinder
not connected for use
must not be stored in
the vicinity of this or
any other appliance.

FITTING AND CHANGING THE GAS CYLINDER
1. Before connecting the appliance to a gas cylinder,
always ensure that the rubber seal on the Regulator is in
position and in good condition, and blow out any dust from
the cylinder opening to prevent possible blockage of the jet.
2. Ensure that the gas cylinder is tted or changed in a
well-ventilated location, preferably outdoors, away from any
source of ignition, such as naked ames and away from
other people.

9
DO NOT store or use
gasoline or other
ammable vapours
and liquids in the
vicinity of this or any
other appliance
3. Make sure that the gas cylinder is kept upright at all times,
screw the regulator onto the cylinder until it is fully engaged.
Hand-tighten only.
4. Never store the cylinder on the hob surface. It is best
practice to store it on the oor in a position where it
cannot be tampered with.
5. If there is a leak on your appliance (smell of gas), take it
outside immediately into a well-ventilated ame free location
where the leak may be detected and stopped.
6. When removing a gas cylinder (e.g. to change cylinders),
rstly close the cylinder valve and then the appliance valve,
making sure the ame is extinguished, before unscrewing
the regulator. Re-t the regulator to a full cylinder following
the same precautions as above.
OPERATING INSTRUCTIONS
Insert 1 x D size battery in the battery compartment. This is the
power source for the automatic ignition.
Battery not provided.
AUTOMATIC IGNITION
The hob has an automatic ignition system.
1. Gently press the control knob for the selected burner and
turn it anticlockwise to the highest power level. While the
control-knob is held down, all the burners will generate
sparks. The ame ignites.
2. Keep the control knob depressed for about 5 seconds
before releasing.
3. Turn the control knob to the required position.
If the burner does not ignite, switch it off and repeat the steps
described above. This time, hold the control knob down for longer
(up to 10 seconds).

An orange-coloured ame is normal. This is caused by the
presence of dust in the atmosphere, split liquids, etc.
If the burner ames are accidentally blown out, switch off the
burner operating control knob and do not try to relight it for at
least 1 minute.
COOKING PANS
The following recommendations can help you avoid damaging
your cookware:
Use pans which are the
right size for each burner.
Do not use small pans on
large burners. The ame
must not touch the sides of
the pan.
10
If the ame does not ignite after 15 seconds, switch off the burner
and open a window or the door to the room. Wait at least one
minute before switching the burner on again.
NOTE: It is important to keep the appliance clean. If the
ignition electrodes are dirty, this may cause ignition
problems. Clean the ignition electrodes regularly with a
small, non-metallic brush. Take care to prevent the ignition
electrodes from sustaining any heavy knocks.
FLAME FAILURE DEVICE
Your hob is equipped with a safety system that cuts off the gas
ow to the burner should the ame extinguish for any reason.
To switch off the burner, turn the control knob to and the ame
will extinguish.
WARNING - RISK OF DEFLAGRATION
FOR YOUR SAFETY
IF YOU SMELL GAS
• Turn off the gas
supply at the
cylinder.
• Extinguish all
naked ames.
DO NOT operate
any electrical
appliances.
• Ventilate the
area.
• Check for leaks
(see LEAK TEST)
• If odour per-
sists, contact
your dealer or
local gas supplier
immediately.
SWITCHING ON MANUALLY
1. Press the control knob for the selected burner and turn it
anti-clockwise to the highest power setting.
2. Hold an igniter or a naked ame (such as a lighter or a
match) against the burner.

CLEANING & MAINTENANCE
11
GENERAL
• Allow the hob and burners to cool down completely before
cleaning.
• Never use sharp instruments, abrasive cleaners, chemical
sprays, steel wool, acid or chlorine based cleaners or steam
cleaners on any part of the hob.
• Frequent cleaning is recommended rather than an
occasional aggressive clean.
EXTERIOR
• The cast iron pan supports on the hob may be removed to
allow easy access to the hob panel.
Place the pans on the pan
supports, never directly on
the burner. Pans should be
placed on the hob carefully.
Always centre the pan over
the burner, not to one side.
Otherwise it could tip over.
Do not place large pans on
the burners near the control
knobs. These may be
damaged by the very high
temperature.
DO NOT use large
pots which may over
hang the body of this
hob.
DO NOT use pot
scourers or abrasive
cleaning product’s on
this hob as these will
permanently mark the
hob.
FLASHBACK (ame burns back into jet)
• If a ash back occurs (indicated by a roaring noise),
immediately turn off the control knob of the affected burner.
• Close the gas cylinder valve and allow the hob to cool for a
few minutes.
• Check for blockages in the burner ports. Clean with com-
pressed air, a small soft brush or pipe cleaners.
• If the problem persists in reuse, have the hob checked by
a qualied technician.

• Wash the stainless steel exterior, pan supports, removable
burner caps and ame ring with hot soapy water and a sponge
or soft cloth.
• Rinse and dry well.
• Acidic spills such as lemon juice, should be cleaned as soon
as possible as these tend to etch into metals if left unattended.
• Routine cleaning will preserve the corrosion resistance and
appearance of the stainless steel for many years.
• Clean the stainless steel as often as necessary (when
noticeably dull or dirty) and use the simplest cleaning method
that will effectively do the job.
• Discolouration of the stainless steel surface can occur due to
high temperature.
• Never wash the ame ring, burner caps or cast iron pan
supports in a dishwasher.
CONTROL PANEL
• Do not use oven cleaners, aerosols, scouring pads or
abrasive cleaners.
• Wipe the control panel with a damp cloth and dry with a dry
lint free cloth.
• Do not attempt to remove any of the control knobs.
IGNITION ELECTRODE & FLAME FAILURE SENSOR
• Ensure that the ignition electrode and ame failure sensor
are always kept clean and the burner is tted correctly (as
indicated in picture below)
