Quick Guide from the Manual

The AGA R3 100-4h is a fully electric heat storage appliance. It requires two 13 amp electrical connections. The cooker is designed to be left at cooking temperature 24 hours a day for optimal performance, though individual zones can be turned off or set to 'e' mode to save energy.

  • Warm-up times: Roast oven (2h 10m), Bake/Simmer oven (2h), Boiling plate (40m), Simmer plate (20m).
  • Safety: Keep children away from hot surfaces. Do not use steam cleaners. Always supervise cooking with fat or oil.
  • First use: Odours and condensation are normal during the first few hours as insulation dries out; open windows to ventilate.

Overview

The cooker features multiple cooking zones:

  • Top Oven: Roast oven (cast iron).
  • Lower Oven: Bake/Simmer oven.
  • Warming Oven: For keeping food warm.
  • Grill: High-speed infrared grill.
  • Hotplates: Boiling plate (hottest) and Simmering plate.

Operation

The R3 offers flexibility by allowing individual control of ovens and hotplates. The 'e' setting reduces the Roast oven to a low bake temperature and the lower oven to a simmer, reducing energy consumption. The heating up time from 'e' setting to full temperature is approximately 1 hour.

Ovens

The upper Roast oven is cast iron and requires seasoning. The lower Bake/Simmer and Warming ovens are enamelled. Food should not be placed in ovens until they reach operating temperature. Use the cold plain shelf in the Roast oven to deflect heat if food is browning too quickly.

Hotplates

The hotplates are operated manually. The boiling plate is used for high-heat tasks like boiling and stir-frying. The simmering plate is used for lower-heat tasks like sauces, scrambling eggs, or slow frying. Do not place items directly on the insulated covers.

Cleaning & Maintenance

Cast iron surfaces (Roast oven and hotplates) must be kept dry and seasoned regularly with vegetable oil to prevent oxidation. Use the supplied wire brush to remove burnt-on debris. Enamelled surfaces should be cleaned with a damp, soapy cloth. Do not use abrasive pads, caustic cleaners, or steam cleaners.

Installation

Installation must be performed by a qualified engineer. The appliance requires two 13 amp 230V ~ 50Hz fused electrical supplies. Ensure adequate ventilation and maintain required clearances from walls and cabinets. The appliance must be earthed.

Practical help

Common problems

Odour during first use

Normal, caused by protective oil burning off. Open kitchen windows to ventilate.

Condensation on top/front plate

Normal during heat-up as insulation dries. Wipe away immediately to prevent enamel staining.

Oven rusting

Cast iron oxidizes if moisture is left. Ensure surfaces are dried and seasoned regularly with vegetable oil.

Grill not working

Ensure the grill door is kept open when the grill is on. Power is cut to the ovens when the grill is in use.

Before use

  • Ensure the kitchen is well ventilated
  • Verify electrical installation is performed by a qualified engineer
  • Season all cast iron surfaces (ovens and hotplates)
  • Remove all packaging
  • Check that the base/hearth is level and can support the weight (310 kg)
