4 How to use the hob burners
Hob burners
Each hob burner is controlled by a separate
gas tap operated by a control knob (fig. 4.1)
which has 3 positions marked on the knob
itself, these are:
– Symbol ●: tap closed (burner off)
– Symbol : High (maximum)
– Symbol : Low (minimum)
Push in and turn the knob anti-clockwise to
the selected position.
Low High
To turn the burner off, fully rotate the knob clockwise to the off position: ●.
The maximum setting of the control tap is for boiling, the minimum setting is for slow
cooking and simmering.
All working positions must be choosen between the maximum and minimum setting, never
between the maximum setting and the “OFF” position.
Fig. 4.1
Electric ignition
The sparks generated by the electrodes close to the burners will ignite the choosen
burner. Whenever the lighting of the burners is difficult due to peculiar conditions of
the gas features or supply, it is advised to repeat the ignition with the knob on
“minimum” position.
Lighting of the hob burners
To ignite the burner, the following instructions are to be followed:
1) Lightly press and turn the knob anti-clockwise, and position the knob symbol
to the indicator printed on the control panel (fig. 4.1).
2) Press the knob to operate the electric ignition; or, in the case of a mains failure light the
burner with a match or lighted taper.
3) Adjust the burner according to the setting required.

Burners Pan diameter
Auxiliary 12 ÷ 14 cm
Semi-rapid 16 ÷ 24 cm
Rapid 24 ÷ 26 cm
Triple-ring 26 ÷ 28 cm
do not use pans with concave or convex bases
Fig. 4.2
Choice of burner
The burner must be choosen according to the diameter of the pans and energy required.
Saucepans with handles which are excessively heavy, in relationship to the weight of the
pan, are safer as they are less likely to tip.
Pans which are positioned centrally on burners are more stable than those which are offset.
It is far safer to position the pan handles in such a way that they cannot be accidentally
knocked.
When deep fat frying fill the pan only one third full of oil.
DO NOT cover the pan with a lid and DO NOT leave the pan unattended.
In the unfortunate event of a fire, leave the pan where it is and turn off all controls.
Place a damp cloth or correct fitting lid over the pan to smother the flames.
DO NOT use water on the fire.
Leave the pan to cool for at least 30 minutes.

9
Correct use of the triple-ring burner
The flat-bottomed pans are to be placed directly onto the pan-support.
To use the WOK you need to place the proper stand in order to avoid any faulty
operation of the triple-ring burner (Fig. 4.3a - 4.3b).
IMPORTANT:
The special grille for wok pans (fig. 4.3b) MUST BE PLACED ONLY over the pan-rest for the
triple-ring burner.

5 How to use the gas oven
General features
Attention: the oven door becomes very hot during operation.
Keep children away.
The oven is supplied completely clean; it is advisable, however, upon first use, to turn the
oven on to the maximum temperature (position ) to eliminate possible traces of grease
from the oven burner. The same operation should be completed for grill burner.
The gas oven is provided with two burners:
a) Oven burner, mounted on the lower part of the oven (wattage: 6,20 kW)
b) Grill burner, mounted on the upper part of the oven (wattage: 4,65 kW).
If hob burners are already in use it is preferable to await about 10 minutes before
operating the oven.
Oven burner
This burner carries out the normal “oven cook-
ing”.
The gas flow to the burner is regulated by a ther-
mostat which maintains the oven at a constant
temperature.
The temperature of the oven is controlled by a
thermostatic probe positioned inside the oven.
The probe must always be kept in its housing, in
a clean condition, as an incorrect position or
encrustment may cause an alteration in the con-
trol of the temperature.
Oven thermostat
The temperature knob is numbered from 1 to (fig. 5.1) indicating the increasing oven
temperature value.
The thermostat which regulates the flow of gas to the oven burner has a safety valve which
automatically shuts off the gas supply when the flame goes out.
The temperature is kept constant on the regulated value.

Gas taps
If a tap becomes stiff, do not force; contact your local COMET Service Centre.
Flexible tube
From time to time, check the flexible tube connecting the gas supply to the cooker.
It must be always in perfect condition; in case of damage arrange for it to be replaced by a
C.O.R.G.I. registered installer.
Cleaning oven parts after use
The oven interior and the chromium plated shelves can be cleaned by damp soapy cloth.
Obstinate stains can be removed with nylon scouring pads and gentle, non-abrasive, liquid
cleaner. Provided the oven is wiped over immediately after roasting, only the minimum of
cleaning should be necessary.
Stainless steel aluminium parts and silk-screen printed
surfaces
Clean using an appropriate product. Always dry thoroughly.
IMPORTANT: these parts must be cleaned very carefully to avoid scratching and abrasion.
You are advised to use a soft cloth and neutral soap.
CAUTION: Do not use abrasive substances or non-neutral detergents as these will
irreparably damage the surface.
