large burners. The flames
should never come up the
side of the pan.
Never cook without a lid
or with the lid half off;
you are wasting energy.
Do not use pans with un-
even bottoms, as they
make the food take longer
to cook and waste energy.
Do not place a pan on
one side of a burner, as it
could tip over.
Never place pans directly
on top of the burners.
Do not use large pots or
heavy weights which can
bend the pan support or
deflect the flame onto the
hotplate.
Avoid using griddles and
earthen ware pots etc. at
maximum heat for a long
time.
Do not remove the wok
pan support and enclose
the burner with a wok
stand as this will concen-
trate and deflect heat onto
the hotplate.
Do not place anything,
e.g. flame tamer, asbes-
tos mat, between the pan
and the pan support as
serious damage to the
cooktop may result.
Use only wok support sup-
plied or recommended by
the manufacturer of the
cooktop.
Always use pans that are
suitable for each burner,
so as avoid wasting gas
and discolouring the
pans.
Always place the lid on
the pan. Use pans, frying
pans and casserole dishes
with thick flat bottoms.
Always place the pan
centrally over the burner,
not to one side.
Place the pan on the pan
support. Ensure that the
burner’s pan support and
covers are properly in

Special considerations for installation over under bench
oven
If installing the cooktop over an under bench oven and connecting
the cooktop via a hose assembly, ensure that the hose assembly is
retained from accidental contact with the flue outlet of the under
bench oven.
Installation procedure
Before connecting the unit, check whether the local connection
conditions (type of gas) are compatible with the unit’s settings. The
model number, type of appliance, gas pressure, gas type, injector
size and total hourly gas consumption are noted on the data plate
attached to the underside of the cooktop base. A duplicate of this
data plate is at the rear of this booklet.
Observe any special conditions imposed by local suppliers (utili-
ties).
1. For cutout dimensions and clearances refer drawing on previ-
ous page. Observe the minimum insertion gap. DANGER! com-
bustion may be affected.
2. Slightly loosen the retaining
screws of the 4 clamping brack-
ets positioned at the bottom of
the cooktop.
3. Insert the cooktop into the bench
cutout.
4. After insertion, from below, swivel the clamp brackets 90°and
tighten them against the bottom of the benchtop.
Electrical connection
An electrical 10 amp socket needs to be within 1 m of the hotplate
to allow electrical connection. The socket must remain accessible
after installation of the appliance.
Important note:
This appliance is connected to the mains (240 VAC) by means of
the connecting lead which must be fixed to the kitchen unit to pre-
vent it from coming into contact with hot parts of the hob (or an
oven installed underneath) and remain accessible after installa-
tion of the cooktop.
16
Wok burner assembly
To assemble the wok burner and pan support place the burner
body onto the burner skirt and the burner head onto the burner
body so the anti-twisting lip fits into the notch in each case.
It is important that these parts are assembled in the correct
position. The cooktop may otherwise not function correctly or
might be damaged.
Wok burner operation
The wok control has 4 settings.
Largest flame = The outer and inner burners are both
operating on high flame.
Large flame = The outer burner burns low and the
inner burner burns high.
Small flame = Only the inner burner burns high.
Smallest flame = Only the inner burner burns low.
For ongoing cooking a variable setting between the flame sizes
can be used.
Ventilation requirements
The use of a cooktop produces heat and moisture in the kitchen.
For this reason make sure that the room is properly ventilated.
Keep natural ventilation openings, such as windows, open or
provide a mechanical ventilation device (e.g. a range hood or
overhead exhaust fan).
Additional pan supports
The wok burner is supplied with an addi-
tional pan support for pans larger than
26mm diameter, i.e. roasting dishes, earth-
enware pots and woks, etc.

10
When connecting the cooktop ensure that the earth wire is con-
nected first and that all wires are connected to the correct termi-
nals.
Gas connection:
The cooktop is adjusted to operate on the gas type specified on
the gas type label located on the
bottom of the unit. If in doubt as to
type of gas available contact the
network operator or gas supplier for
confirmation of gas type.
The cooktop must be connected to
the gas supply with upstream con-
nection of an isolation valve in ac-
cordance with the respectively valid regulations. We recommend
that the isolation valve be fitted prior to the cooktop to enable
isolation of cooktop from gas supply. The valve must be easily
accessible at all times.
This appliance may be connected with a hose assembly, class B or
class D. If connected with a hose assembly ensure that the supply
connection point is accessible with the appliance installed.
The position of the inlet connection is measured from bottom RH
rear of unit, 45mm centre line from rear and 27mm centre line for
RH side.

ers and one wok burner. All burners are fitted with electronic igni-
tion and safety shut off device.
1. Wok burner 4. Medium boiling burner
2. Small boiling burner 5. Medium boiling burner
3. Large boiling burner 6. 5 control knobs
Boiling burners operation and ignition
The boiling burners have two heat settings.
Large flame = highest setting
Small flame = lowest (simmer) setting
The highest flame setting is used for initial
boiling. For ongoing cooking a variable
setting between high and low flame can
be made.
To activate the burner depress the control
knob and turn to ‘high flame’ position.
Keep knob depressed for approx. 6-7 seconds to allow the safety
shut off to activate. The flame will extinguish if the knob is released
too soon.
If ignition fails depress knob and try again. If flame is not estab-
lished in 15 seconds release the control knob and open a door and
wait 1 minute before attempting a new ignition procedure.
If the burner flames are extinguished - for whatever reason - turn
OFF the control knob and wait at least one minute before retrying
to ignite the burner.
Ensure that the flames do not extinguish when you reduce to low
flame quickly.
To turn off the gas supply to a burner return the control knob to the
‘OFF’ position.

11
3. Check for gas soundness at connections. NEVER use a naked
flame to check for leaks.
4. Check correct operation of each burner individually and in
combination. Burner flames should be clear blue, with no yel-
low tipping. If the burners show any abnormality check that
burner heads are correctly located and refer to the ‘mainte-
nance trouble shooting’ chart on page 20. If satisfactory per-
formance can not be obtained, contact Sampford & Staff or
the local gas utility. For service contact number refer back page
of this booklet.

Important information
The top plate of the cooktop consists of a very resistant ceramic
and with proper handling will stand up to all household stresses.
Before using the cooktop for the first time, please read the follow-
ing practical tips.
❍This appliance is intended for domestic use only
❍Do not use the ceramic top as a work surface or storage space.
❍Do not let pans with rough or textured bottom surfaces rest on
the ceramic top. They can cause scratching when moved around
on the top.
❍Do not drop hard or sharp objects onto the top. This may dam-
age it.
❍Never use two burners to heat one single receptacle.
❍The cooktop must be switched off immediately if the ceramic
top develops any cracks, splits or fractures. If this should hap-
pen, switch off the power and gas supply.
❍Do not use the cooktop to heat a room.
❍Never prepare food in aluminium foil or plastic containers on
the hob. The material melts on.
❍Melted-on sugar or food containing sugar should be cleaned
off immediately using a glass scraper, otherwise they could
cause damage to the ceramic surface.
❍The surfaces of the cooktop, trivets and burners will become
hot during operation. Small children must be kept at a safe
distance from the appliance.
❍Do not use large-diameter pans on the burners nearest to the
control knobs, as the flames might reach them, making them so
hot that they could cause injury.
❍Grease and oils are flammable if overheated. Always stay near
the oven when preparing food using grease and oil, e.g. french
fries.
❍Never cover the ventilation openings at the rear of the cooktop,
e.g. with a tea towel.
❍Only ignite the gas burners when all the burner components
are correctly assembled.
❍Never flambe dishes while using a range hood or extractor
fan. The flames could set the range hood or extractor fan on
fire.
❍Leads from electrical appliances must not touch the cooktop.
They will melt on and the cable insulation will be damaged.
❍Always watch pressure cookers until they reach the correct pres-
sure. You should first set the burner to highest level and reduce
the heat when the required pressure has been reached.
In the event of a fault
disconnect the electrical
power to the cooktop
and shut off the gas
supply.
Contact your local gas
supplier or service
agent. The service
agent contact details
are at the rear of this
booklet.
