The Dome Ashtray gives you better flame and temperature control with wood or charcoal, but it is not compatible with Gen 2 ovens. Here is how to use it and keep ash in check.
Quick answer
The Dome Ashtray is a control module that improves temperature and flame management when you burn wood or charcoal in a compatible Dome. It also makes ash removal easier between bakes. However, it is not compatible with Dome Gen 2 or Dome XL Gen 2, so check your oven model before buying. For Gen 2 owners, rely on the built-in ash management and regular cleaning instead.
Why ash buildup becomes a problem in a wood-fired oven
Ash is an unavoidable byproduct of burning wood or charcoal. In a Dome, ash collects in the fuel tray and around the burner area. If left too long, it restricts airflow, which makes the fire harder to control and can cause temperature swings. It also creates more mess when you open the oven door or slide a pizza in. The Dome Ashtray is designed to give you greater control over both flame and temperature by managing how air moves around the fuel. That means less ash flying around and more consistent heat for your bakes.
How to fit and use the Dome Ashtray
The Dome Ashtray is a drop-in module. It replaces the previous ashtray that shipped with earlier Dome units. Fitting is straightforward: let the oven cool completely, remove the old ashtray, and slide the new one into place. Make sure it sits flush and does not obstruct the fuel tray. During use, empty the ashtray when it is cool and the ash has fully burned out. A good habit is to check it before every bake and empty it after every two or three sessions, depending on how much fuel you burn. Never empty hot ash into a plastic bin or paper bag. Use a metal container with a lid.
When the Dome Ashtray is the right fix
If you cook with wood or charcoal in a compatible Dome and find that your fire is difficult to control or that ash interferes with airflow, the Dome Ashtray is a practical upgrade. It is also a good choice if you want to reduce the amount of ash that escapes when you open the oven. The module is designed for Dome models that accept it, and it is not compatible with Dome Gen 2 or Dome XL Gen 2. If you own a Gen 2 oven, do not buy this ashtray. Instead, follow the cleaning routine in your manual and use the oven’s built-in ash management features.
Diagnosis: Ash and airflow issues
- Symptom: Fire struggles to stay lit or temperature spikes: Ash may be blocking airflow around the fuel tray, or the ashtray is full. A clogged ashtray restricts oxygen and makes the fire unpredictable. Let the oven cool, remove the ashtray, and empty it. If you have a compatible Dome, the Dome Ashtray can help maintain consistent airflow.
- Symptom: Ash blows around when you open the door: Excess ash in the fuel area gets disturbed by air movement. This is common when the ashtray is overdue for emptying or when the fuel tray is overfilled. Empty the ashtray more often and avoid overloading the fuel tray. The Dome Ashtray is designed to contain ash better than the original version.
- Symptom: You are unsure if the Dome Ashtray fits your oven: The Dome Ashtray is not compatible with Dome Gen 2 or Dome XL Gen 2. It is intended for earlier Dome models that use the original ashtray design. Check your oven model before purchasing. If you have a Gen 2, stop here and do not buy this accessory. Use the built-in ash management and regular cleaning instead.
Product facts
- Dome Ashtray: The Dome Ashtray is not compatible with Dome Gen 2 or Dome XL Gen 2. It provides greater temperature and flame control when using wood or charcoal in Dome. It is an update to the previous version that shipped with Dome units. If you own a Gen 2 oven, this accessory will not fit. For older Dome models, it offers improved control and easier ash handling.
