The AGA R3 Series Cookers - R3 170-5i

A contemporary AGA - on all the time for a gentle background warmth

AGA Everyday eR3 170-5i in Cream

1716mm wide, no flue needed, cheap to run, no annual servicing and an induction hob.

It's everything you'd expect of an AGA: true AGA cast-iron oven for 'radiant-heat' cooking; second baking/simmering oven; a hotplate with two heat settings; a warming oven, a high-speed infra-red grill and a three-zone induction hob.
At the left side there's also an large fan convection oven with simmering hotplate above: traditional and modern rolled in to one.

Left Hotplate

A large AGA Simmering Plate

Heats, with its own control, to AGA 'Simmering' temperature (about 200C) and has a durable outer section which provides extra (unheated) space around the outside of the main hotplate to rest pans.

Centre Hotplate

Centre - a dual-function hotplate: Simmering or boiling.

The outer section around the main hotplate is useable and provides extra cooking area (albeit at a lower heat) to the main hot-plate.

Induction Hob

The R3 170-5i has a three-zone induction hob.

With touch-controls, pan detection and numerous automatic functions the induction hob adds a new level of functionality to your AGA.

AGA Installation FAQs


The AGA R3 Series doesn't need a raised plinth.

A clearance of 650mm is required above the hob to any surface/extractor.

A clearance of 116mm is required to the left side to allow the oven doors to open far enough so the trays can be slid in and out without being obstructed by the door liner.

There is a 25mm spacer fitted to the back of the cooker which should not be removed.

This ensures the correct gap is maintained to any wall construction and allows the cooker to be fitted up to a plasterboard or 'combustible' wall.

There will always be a small (14mm) gap behind the cooker's top plate to the wall. (Due to the top-plate overhang of the back - see diagram.)

Electrical Connection and Load

The R3 Series 170-5i needs three 13amp supplies.

These should NOT be socket outlets (the big cables don't fit in a plug-top).

Ideally install three 16amp circuits with isolating switches in an accessible position next to the cooker, terminating in separate cooker connection points within the reach of the cooker's three supply cables.

You could also adapt a standard 32amp cooker circuit to feed two of the supplies and connection points, with an additional 13amp supply for the fan oven and simmering plate, or even use a normal socket [ring] circuit providing it won't be overloaded with the AGA's three 13amp supplies in use.

The switches must be in the same room, within 2m of and NOT BEHIND OR DIRECTLY ABOVE the cooker. In a base unit to its side is ideal.
