USING THE AUTOMATIC COOKING FUNCTION
Using this function on the timer allows the user to select the amount of time the appliance is on and the finish/off time.
HINTS ON THE USE OF THIS FEATURE
*
The AGA should be COLD before starting any automatic cooking where there is a delay in the start time.
Because the AGA is made from cast iron and will therefore retain the heat for a number of hours after it is turned
off, food should NOT be loaded into the appliance for automatic cooking if the AGA has been used earlier in the day,
or is slightly warm, even if it has been turned off for some hours.
*
Only choose foods that require the same amount of time to cook and require the same oven temperature.
*
Food should be as cold as possible when it goes into the oven, especially if there is a delay in the start time. Food
should be thoroughly thawed before it is put into the oven.
*
Warm food should NEVER be placed in the oven if there is a delay to the start of cooking. ie Stews prepared by
frying the meat/vegetables should be cooked immediately.
*
Dishes containing left-over food should not be cooked by this method.
*
On warm days or in centrally heated houses, the delayed start should be minimum, to avoid the growth of harmful
bacteria.
*
Dishes containing liquid should not be too full, to prevent boiling over.
*
At the end of the automatic cooking time although the AGA will switch off automatically it will remain hot for hours
after. FOOD MUST BE REMOVED IMMEDIATELY OR OVER COOKING WILL RESULT.
*
This facility should be used for the main oven only - NOT the lower oven or hotplate.
*
When starting from cold add an extra 40 minutes to the cooking time as an allowance for the AGA to warm up.
*
If a full load is to be cooked add an extra 30 minutes to the total cooking time.
*
ENSURE FOOD IS THOROUGHLY COOKED BEFORE SERVING
*
In the event of a short term power failure the auto cook will automatically adjust the amount of cooking time. As the
AGA retains its heat - OVER COOKING MAY RESULT.
26
MAIN OVEN OPERATION
Note: care should be taken not to touch the hotplate, oven combustion chamber door and flue areas unless a
insulated glove is used, as these areas are hot working surfaces and will burn unprotected skin.
z
z
z
z
z
z
The oven is indirectly heated from the outside by hot gases from the heat source so that no flame or elements within
the oven means full use can be made of the whole cooking area.
The oven is hotter towards the top than the bottom.
To heat the Roasting/Baking and increase the hotplate temperature - turn the cooker control knob to desired setting
as required.
There are 5 runners or shelf positions within the oven on which the grid shelves, solid shelf and meat roasting tin fit
directly.
When left on L setting, your Roasting/Baking oven will maintain a low idling temperature suitable for slow cooking.
As the AGA is made of cast iron, the time for the appliance to heat up and cool down is longer than with a
conventional oven. As an AGA user, you will soon get used to thinking ahead.
Hints
*
Do not forget that the thermodial reflects the temperature in the middle of the oven; by moving the food
higher or lower, or by use of the solid plain shelf, a hotter or cooler temperature can be achieved.
*
The main oven has good all-around temperature. You’ll notice joints of meat gain color more quickly
than in a conventional oven. This is due to the heating from all around the cast iron oven (not just an element
or gas flame). Moisture is quickly sealed in, giving a succulent moist finish.
*
Heat loss when you open the oven door is not as great as that from a pressed metal box type oven; so, you
can look to see how a cake is cooking without it sinking.
*
For perfect baking results, some food such as trays of cookies, small cakes or items nearer the top or on the
floor of the oven, may need turning during cooking. Alternatively, use a lower shelf position and place the
cold plain shelf on the top runner above the cakes to diffuse the heat.
*
One of the many benefits of the cast iron Roasting/Baking oven is that when the oven is hot, the floor of the
oven is hotter than that of a conventional cooker and can be used directly for cooking.
*
No need to bake quiche pastry cases “blind”, just place the flan dish on the oven floor for “soggy-free”
pastry or finish off the base of fruit pies etc. This position is also useful for shallow frying (a cast iron dish
is recommended) with the added advantage that fat splashes are carbonized so cleaning is minimal and
cooking smells are taken away through the flue.
IN THE EVENT OF A POWER FAILURE
During a power failure the appliance will not operate.
If a power failure occurs the memory of the timer is lost and therefore, will need to be reset. This means that the
appliance will not operate until the time of day has been set.
27
COOKING WITH YOUR APPLIANCE
Broiling
The top of the oven is where broiling takes place. When the Roasting/Baking oven is hot, use the meat tin with a grill rack
(used on the highest position) so that the fat can drip into the tray. Position the food on the rack and put into the oven on
the highest runner. The heat from the cast iron roof of the oven will cook and color the food. Turn as necessary.
Turn the grill rack over to the lowest position and it becomes a trivet for roasting meat and poultry. It is also useful as a
cooling rack.
The Hotplate
The rise in temperature of the hotplate corresponds with rise in oven temperature. The higher the Roasting/Baking oven
temperature, the hotter the hotplate. It is graduated, being hotter on the right side suitable for boiling, and cooler on the
left side for simmering and slower cooking.
Hints
*
To get the best results when cooking on the hotplate always use good ground bases. This ensures maximum
contact and heat transfer from the heat source to the food being cooked.
*
The hotplate can be used directly, for making toasted sandwiches, drop scones, etc. See the AGA cookbook
for details.
*
Keeping the hotplate free from crumbs and debris will also maximize efficiency. Even a few small crumbs on
the hotplate will considerably slow down the time it takes for a kettle to boil.
*
Keep the hotplate as hot as possible by always keeping the lids closed when not in use. This also conserves
fuel.
The Simmering/Warming Oven
*
The temperature of the cast iron Simmering/Warming oven is dependent on the temperature in the Roasting/Baking
oven.
*
As a guide, it is approximately half the temperature of the Roasting/Baking oven.
*
This means it can be used as a cooking oven, when the Roasting/Baking oven is at a higher temperature, ideally
200ºC (392ºF) or slightly higher. Food such as casseroles, meringues and milk puddings can then be cooked
satisfactorily.
*
When cooking a casserole or meat dishes in the Simmering/Warming oven, always start off cooking somewhere else
on the AGA first. (ie allow casseroles to come to a boil, and cook for 5-10 minutes on the hotplate or in the
Roasting/Baking oven before being transferred to the Simmering/Warming oven).
*
Although there are runners on the sides of the oven for the grid shelves/meat tin, dishes may also be cooked on the
floor of the oven.
*
Note that if the appliance is left on high setting or run continuously for a long period of time, the temperature of the
Simmering/Warming oven may climb higher than half of the Roasting/Baking oven temperature.

It is not advisable to put wet clothes on the handrail: this may craze the enamel.
To keep the vitreous enamelled surface bright and clean, wipe over daily with a soapy damp cloth, followed by a
clean dry cloth.
Wipe off any condensation streaks on the front plate as they occur or the vitreous enamel may be permanently
discolored.
If milk or fruit juice or anything containing acid is spilled on the top plate or down the cooker, be sure to wipe it
immediately or the vitreous enamel may be permanently discolored.
Keep a damp cloth handy while cooking, to wipe up spills as they occur, so they do not harden and become more
difficult to remove later.
For stubborn deposits, gentle localized soaking, not flooding, is easier than rubbing. Hot water and detergent will
soften most burnt stains in about 10 minutes.
A soap impregnated pad can be carefully used on the vitreous enamel.
Oven Door Linings
z
Using oven gloves, carefully lift off the oven doors and lay them on a tea towel to protect the enamel. They can then
cleaned with a cream cleanser or soap impregnated pad. Do not immerse the doors in water as they are packed with
insulating material which will be damaged by excessive moisture.
Insulating Lids

Ensure that the probe insulation is free from cracks or
moisture.
Check that the probe is not in contact with other metallic
parts of the burner.
3. Check the burner is effectively grounded and bonded to
the incoming ground wire from the main supply.
4. Check for interference to the flame signal from the
ignition spark. This can be determined with a d.c microammeter (μA). Connect the meter between the terminal
and the incoming wire to the flame probe. Correct
polarity of the meter connections must be correctly
observed with the positive side of the meter connected
onto terminal at the control box. If flame is established
and the meter tends to move in a reverse direction, this
can be an indication that the ignition is causing
interference to the flame signal. It may also be an
indication that there is insufficient earth contact with the
flame. A correct reading should be approximately 3 - 7
μA.
5. Change control box if necessary.

Servicing or Fault
BURNER RESET
If a fault occurs on the burner, then it automatically shuts
down and the red button on the front base plate will be
illuminated. This can be reset, after 10 seconds by
depressing the reset button. The reset button is located in
the lower base panel.
OPERATING BY PRESSING WITH FINGER ONLY
Please wait at least 10 seconds between resetting the
lockout button. If resetting the lockout button does not light
the burner immediately, it will be necessary to repeat the
sequence.
Continued lockouts indicate a burner or gas supply
malfunction. This fault should be diagnosed and rectified.
In the event of repeated failure, close the gas valve and
disconnect electrical supply to the appliance and contact
your installer/service engineer.
FLUE SAFETY DEVICE
For safety purposes, a flue safety device is installed. This will
only operate under adverse flue conditions, If the switch has
been operated, it should be pushed into reset and the pilot
re-lit. If this problem persists contact your local engineer to
determine and rectify the cause. It is important not to reset
more than once as this may indicate a flue blockage.
GAS LEAK OR FAULT
If a gas leak or fault exists or is suspected, the unit must be
isolated from the gas and electrical supply. The appliance
must not be used until the fault has been rectified.
Advice/Help should be obtained from your Installer/Servicing
Company.
POWER FAILURE
In the event of a short term power failure, the clock display
will disappear and then return on the power supply being
reinstated.
However if the power supply is interrupted for any length of
time, the clock display will be lost. Follow procedure ‘TO SET
TIME’.
SERVICING
With normal use the cooker will need annual flueway
cleaning and burner maintenance, which should be carried
out by a qualified engineer.
A HOT APPLIANCE CANNOT BE SERVICED.
The cooker thermostat knob should be turned OFF the night
preceding the day of the servicing so that the appliance will
have cooled down by the following morning.
