Depth. (front to back) (All Models)

Dimension 'J' is overall extremities including the handrail, at 756mm. Allow extra if AGA is sited away from the rear wall with a gap.

Dimension 'K' includes the clearance necessary for the doors to open, 1125mm.

Dimension 'M' refers to the depth up to the overhang of the top plate, 698mm.

Dimension 'D' at 679mm, is the depth of the cooker base plate and to which any plinth or hearth should be constructed, but allow extra if the cooker is spaced away from the rear wall.

Height. (All Models except TCA)

'C' is the height to the working surface. --- 851mm (910mm TCA model)

'F' is the distance reached by the lids when fully open - 1330mm (1385mm TCA model), but allow extra clearance for comfortable handling.

'B' Some models (Electric & Gas PF) have a raised, cast-iron shroud along the top rear edge at a height of 967mm, others merely have a raised lip at 889mm. (945mm TCA model)

Solid Fuel, Oil and Gas (OF) fired models have a top flue connection, 'F' at a height of 959mm for Kerosene Oil & Solid Fuel, 1151mm for diesel and 1035mm for Gas cookers.

Width

IMPORTANT. It is a natural feature of cast iron components that the finished dimensions will vary. Consequently, if the AGA is to be situated into a tight recess, then at least 10mm should be added to these dimensions to ensure sufficient clearance.

AGA Cookers are assembled from modules of standard widths, according to the module chosen, but regardless of fuel type.

2 and 3-oven Models. Dimension 'A' is the overall width at 987mm.

Note that the flue pipe connection is not central, but is off-set towards the right hand side at dimension 'E' 467mm. This applies to all open flue models.

4-oven Model. Dimension 'B' is the overall width at 1487mm.

An Electric or Gas AGA module option may be fitted to the left hand side of the 'parent' AGA cooker and the dimensions are then increased as shown below.

Add 611mm to overall width.

2 and 3-oven cookers become 1598mm.

4-oven becomes 2098mm

There are also several other factors affecting the width of the recess and the clearances required.

If the right-hand wall protrudes forward beyond the front of the AGA, then additional clearance is required as shown in dimension 'W' 116mm.

This is to allow the oven doors to hinge open beyond 90 degrees, so as to be able to remove the oven shelves etc.

3-oven models also require this gap on their left hand side.

On a kerosene oil-fired cooker, where the control valve is sited on the right-hand side panel there is no need to consider the 116mm, as there is a separate requirement for a clearance of 300mm. See below.

A kerosene oil-fired cooker has an oil control valve fitted externally to its left or right hand side panel, thus extending the overall width, although it can be accommodated within the adjacent work unit.

(Does not apply to Diesel (gas-oil) models.)

Where the cooker is fitted in a tight recess then an extra clearance of 'M' 300mm should be added to the normal width dimensions.

If the right hand wall extends beyond the front of the AGA, and the oil control is fitted to the right-hand side, then the gap should be 300mm on the right, which will also take into account the 116mm referred to above, for door opening clearance.

The weights quoted below are approximate and spread across the full area of the cooker's solid baseplate, as shown.

Note the exception with the 30-amp electric models, which have their heat store resting separately on the hearth.

The hearth or floor below the AGA must be strong enough to carry these weights as well as the extra weight of any plinth or slab used.

If the kitchen floor is suspended, it may require additional support underneath. Please check with your builder or a structural engineer.

The hearth must be also be non-combustible for a minimum thickness, dependent on the fuel type. See also the individual site requirements pages.

Any plinth or hearth must be absolutely level in all directions.

Pre-fabricated plinths are available for most AGA models extending the height by 60-75mm.

With some models of AGA, you have the option of obtaining domestic hot water.

This provides an economic way of producing 410 litres (90 gallons) of hot water, spread out over a 24 hour period, regardless of how much cooking is carried out.

With the 2-oven oil fired AGA only, there is an optional larger boiler available, which will increase the domestic hot water output to 614 litres (135 gallons) over the same 24 hour period.

Hot water is generated within the AGA and circulates through a conventional, open vented, gravity system into a 190 litre storage cylinder, located within 5 metres of the AGA. With the larger 135 boiler, a correspondingly increased, 280 litre, storage cylinder is required.

Does the AGA produce domestic hot water for free?

There is a slight increase in the fuel consumption of a boiler model, but it is still an economic way of obtaining hot-water.

Will the hot water demands affect the AGA's cooking performance?

No. The boiler draws its heat indirectly from the burner chamber/ fire-barrel.

What happens if we do not use all the hot water produced by the AGA?

There will be an increase in the temperature of the domestic hot water, but overheating is unlikely under normal circumstances.

What if we need more hot water than the AGA will produce?

There is no reason why an electric immersion heater cannot be fitted to the cylinder, for occasions when top-ups are required. Alternatively, it is sometimes possible to interconnect the AGA into a 'shared system' with another boiler or heat source. Special controls and plumbing arrangements will be required, and the AGA must be allowed to contribute the bulk of the heat required. A special 'twin coil' cylinder is often used in such circumstances.

Can we fit a thermostat to the AGA to control the hot water temperature?

No. If there are concerns regarding the upper temperature limit, we recommend fitting a mixing valve at the cylinder outlet.

Can the AGA be used to supply a radiator?

The AGA is designed to release just enough heat from its boiler to generate 90 or 135 gallons of hot water over 24 hours, dependent on the model. Fitting even a small radiator would seriously reduce the amount of domestic hot water available.

What about a towel rail?

As above, fitting a towel rail will reduce the hot water production. In some households, this might be useful, if demands for hot water are limited, in which case, the towel rail will act as a heat-leak.

What happens in a hard water area?

The plumbing system for an AGA should be of the 'indirect' type, in which case lime-scale will not be a problem. Older AGA's may have been connected to 'direct' systems and may require occasional de-scaling, if the boiler becomes noisy.

Can the AGA be connected to a 'sealed' hot water system?

An AGA must be connected to a vented system, with an appropriate feed and expansion tank. Some proprietary 'Thermal Store' cylinders may be connected to an AGA. This allows the hot water to be delivered at the taps at mains pressure. Further details of this type of system and the necessary controls required, should be obtained from the relevant cylinder manufacturer in conjunction with your AGA engineer.

We no longer want hot water from our AGA. Can we just disconnect the boiler?

To make the AGA safe, the boiler will need to be removed and insulation material put in its place, to maintain efficiency. Some adjustments may also be required to the oil control valve or gas burner. On 2-oven models, this work is straightforward, but 4-oven models require rather more adaptation. Please ask your AGA Engineer for further details.

The water supply to the house is to be off for a short while. What should we do?

The AGA may be left on, preferably turned down low. Do not draw any hot water off.
