The installation process - installing 2 refurbished AGAs

We are pleased to be listed by both The Range Exchange and Classy Cookers as recommended installers. Both are Cheshire based, supplying high quality refurbished AGAs and AGA appliances nationwide.

We were recently approached by two Range Exchange customers to install their newly purchased refurbished AGAs.

AGAs, unlike conventional appliances, are not delivered as one piece and must instead be built on site. The AGA is delivered flat packed with all necessary components. Besides the obvious logistical challenge of moving an appliance of such size, weight and immobility, doing so risks the integrity of the cooker itself. An AGA is not a rigid appliance; when moved, seals can become broken and levels distorted. Alongside these considerations are the varying services on each site – the AGA is built according to whether the services are coming from the right or the left side of the cooker.

 An AGA installation takes a full day for two engineers or a day and a half for a single engineer. 

Installation of a 4 oven Oil AGA in Classic Cream, with standard warming plate

All AGAs require some sort of base – usually concrete or metal. In this case a 60mm black powder coated metal base was in place. A 6mm oil line was first installed beneath the base plate.

To begin the main build, the hot cupboard was placed on the left hand side of the base and levelled; careful levelling is essential at every stage of an AGA build. The main cast base plate was then locked into place with the hot cupboard; the ash pit and oven stays screwed into the base and levelled. The bottom oven and ash pit were lowered onto the stays, then the front plate attached to the oven and ash pit and levelled both horizontally and vertically.

A loose conducting plate was placed on the bottom oven with a small amount of insulation surrounding it. The top oven was lifted into position and also attached to the front plate. Side panels, back panels and stay rods were put into place. The top plate was rested loosely in situ as a guide, the simmering spot put on the top oven and heights and levels set. The top plate was then removed, more work being necessary before its final positioning.


Next, the conducting tunnel for the hot cupboard side was sited, the barrel ropes placed on top of the ash pit and the barrel dropped into place. The barrel was then attached to the top oven using the gasket provided. The truncheon bolts were fitted to the barrel, the hotspot placed into the barrel and heights and levels set. Once this was achieved, the barrel was tightened and the barrel ropes pulled to create a seal. The conducting plate on the top oven was then pulled across using a crow bar. The flue manifold was fitted and the shroud and remainder of the flue.

The final components, including thermostat tube and oven vent pipe were then fitted. The next stage was to pack rock wool around the oven tunnels, around the base of the barrel and around the hot cupboard conducting tunnel. The cooker was then ready to pack. Around 4 bags (400ltrs) of vermiculite were then poured into the cooker and using a riddling stick the vermiculite was rodded into all the cavities. Once satisfied with the quantity of vermiculite, the top of the vermiculite was covered with rock wool.

The lids were attached to the hot plate before installing. The top plate was then fitted and levelled using adjusters and the hot cupboard top plate fitted.  We then adjusted the hot spot and simmering spot slightly to achieve correct levels. The hand rail and finally the oil burner and an oil control valve were fitted and the appliance commissioned. 

An involved process but the result – a resilient and beautiful workhorse that will give many many years of benefit and joy.

In this case a concrete base was already in place. A gas burner was fitted in place of the oil burner and oil control valve and the installation conducted as above.
