How to light your Gas Aga Cooker

Looking for Lighting Instructions for Gas Aga Cookers? Just follow the steps below.


At Saltire Cookers, we refurbish traditional models of Aga cookers, including gas, as well as oil and our popular electric models.

We also offer Electric Conversions for cheaper running costs, and refurbishments for existing cookers - we're busy boys!

If you need to light your Gas Aga cooker, we've got some easy-to-follow instructions here.

Nowadays, Gas Aga Cookers are usually running from two types of gas valve - Maxitrol or Eurosit. 
Some use older Mark 1 or 'Junkers' burners, which are discontinued with no spares available.

How to Light Maxitrol Gas Valves


If your flame has recently extinguished, wait at least 3 minutes before attempting to relight.


1. Identify your burner control dials - Temperature control is the top left black dial, and the Main Control is the top right black dial.

2. Turn the temperature control dial down to the minimum setting (either number 1 or the small end of the scale - depending on age/type of Maxitrol valve).

3. Turn the Control dial to its OFF position (the 3 o'clock position as you're looking at it).

4. Make sure the main Gas Stop Tap is turned to its ON position.

5. Turn the Control dial anti-clockwise, to the star/spark symbol.

6. Depress the whole Control dial and keep it down for at least 5 seconds - to allow gas to enter the flow pipes. Keep it pressed down for the next step.

7. Keeping the Control dial pressed down, turn it anticlockwise to the next position (the small flame symbol), to activate the piezo. Keep it pressed down for the next step.

8. With the small pilot lit, keep the Control dial depressed for a further 10 seconds for the flame to establish and heat the thermocouple. If it extinguishes, try the process again.

9. Turn the Control dial anti-clockwise to the large flame.

10. Now turn the Temperature control dial to the low fire position (either 1-2 on numbered dials, or very slightly into the white zone, on dials with a scale). You should see a small flame appear through the glass inspection window into the burner.


Leave this small low-fire flame for at least an hour, for all your flue ways to heat up enough for up draught.


After an hour, turn the Temperature control dial to the normal operating position (either between 5-7 for numbered dials, or middle of the green band for dials with a scale).


After a further 8hrs, your cooker should be at temperature. Any adjustments to the temperature dial position should be made sparingly, and your cooker left overnight for the heat to settle before any further readings taken from the heat indicator/thermometer on the cooker front plate.


How to Light Eurosit Gas Valves


If your flame has recently extinguished, wait at least 3 minutes before attempting to relight.


1. Turn the cooker to its OFF position (solid black dot on the dial) and make sure the Gas Stop Tap is turned on (photo above).

2. Turn the dial anticlockwise to the star/spark symbol.

3. Press the dial down with one hand. Using the other hand, after a few second, repeatedly press the ignitor button (to the left) until a small pilot light is established, visible through the viewing window into the burner.

4. Keep the dial depressed for a further 30 seconds once the pilot light is established. If it goes out, wait at least 3 minutes before relighting.

5. After 30 seconds, slowly release the dial, then turn to the low fire setting (the small white box on dials with the scales, or for numbered dials, the start of the numbers). You'll see the main burner bar ignite, through the small glass viewing window.


Leave the burner in low fire for at least an hour, for all your flue ways to heat up enough for up draught.


After an hour, turn the dial to the normal operating position (either between 5-7 for numbered dials, or the green band for dials with a scale).


After a further 8hrs, your cooker should be at temperature. Any adjustments to the temperature dial position should be made sparingly, and your cooker left overnight for the heat to settle before any further readings taken from the heat indicator/thermometer on the cooker front plate.

Our black steel plinths are available to add onto your cooker order if required. They add additional height to the overall Aga dimensions and are available in multiple heights to suit your kitchen design. Traditionally, these British-made Aga Cookers were 851mm from the base to the top of the black enamelled surface. When do you need a plinth? If your worktop or ideal working height is taller than 851mm and you want your Aga Cooker to match them, you'll need a plinth underneath. Brand new Aga Cookers (as well as our ESSE and Everhot cookers) have a fixed height plinth built into the cooker body. If you need these raised higher, you'll need to lay marine-grade plywood or concrete at the required height before installation. What sizes of plinths are available? Our plinths are available in 50mm to 80mm sizes. They also allow for levelling of the base before the assembly of the cooker begins. How do I choose my plinth size? When choosing your required height, you should consider your finished floor height vs your worktop height. It's standard for Aga Cookers to finish slightly proud of the worktop, since the top plate is curved rather than a right-angle ( photo shown below ). If you were to finish level with the worktop, you will have a bigger 'valley' in-between, where crumbs and debris love to collect! Usually, the plinth is seated onto the subfloor, with finished flooring/tiles ran up to and around the plinth once the cooker is built. Alternatively, you can either seat the plinth directly onto the finished floor/tiles, as long as they can bare the weight of the cooker, or we can raise the plinth using the adjustment legs, to allow the finished floor to tuck underneath slightly ( photo shown below). If choosing this option, you should bare in mind the supporting feet in each corner of the plinth start at around 20mm from the front of the plinth. This means your flooring could run underneath for a depth of around 20mm if preferred. After the cooker is built, there are NO adjustments in height, without a strip down and rebuild. What do Aga Cooker plinths look like?

The internal cavities of Aga Cookers have historically been filled with loose-fill insulation. Inside the cooker body, there are lots of pockets and gaps around the cast iron conductions and burner casings etc. The insulation was poured inside after the build was complete, to rid the cooker of air pockets and insulate the cooker body. Diatomaceous Powder Insulation Early models of Aga cooker, like the Standard models made from the 1950's through to the Deluxe 1974 models (and some post-1974 models), would have originally contained Kieselguhr insulation power (or 'Diatomaceous Earth'). You can identify your model here. This is a fine, talc-like insulation, made from crushed up fossils called diatoms. It's satisfying to touch, but VERY messy to work with and instantly becomes thick clay once exposed to water or moisture. The good news is that amorphous diatomaceous earth is non-toxic. As with anything in powder or dust form - minimising exposure is key. You don't want to be breathing in lung-fulls of any dust or powder. If you're working with it, the proper PPE should be used; not just cloth or paper dust masks. Whilst the loose fill insulation may be ok, these models are still the most at risk for any asbestos exposure. AGA used asbestos rope seals inside their cookers for many years. These seals and gaskets are found inside the body of the older models explained above, and also around the lids and doors. Over the lifetime of these cookers, many of these gaskets and rope seals have been replaced for modern (safe) equivalents. AGA have previously reassured engineers and customers that undisturbed, these seals pose little risk and were of 'dust suppressed' or 'tightly woven' formats. Many of them have been exposed to moisture or grease over time which hardens them, meaning they're less friable in nature. They recommend that really old models of cooker are removed in one piece if possible and disposed of professionally.
