Learn how to install and use the Dome XL (Gen 2) Door to lock in heat, control temperature, and bake or smoke with precision.
Quick answer
Install the Dome XL (Gen 2) Door to trap heat, stabilize oven temperature, and add smoky flavor without burning your fuel.
Why use the Dome XL Door for heat retention
The Dome XL (Gen 2) Door is a twin-walled, insulated accessory that locks heat inside your oven. Without it, the open mouth of the Dome XL lets heat escape rapidly, making it hard to hold steady baking temperatures or to slow-roast. With the door, you can bake bread at consistent heat, hot-smoke meats, or slow-cook without constantly feeding the fire.
What the door does differently
The door is built from ceramic-coated 304 stainless steel with double-wall construction. That means it reflects heat back into the oven and minimizes radiant loss. It also includes cutouts for meat probes, so you can monitor internal meat temperature without lifting the door. And if you toss fresh herbs like rosemary onto the ember bed before closing the door, the chamber fills with herb-infused smoke for extra flavor.
How to install and use the Dome XL Door for better heat retention
- 1. Attach the door while the oven is hot: Wait until your Dome XL fire has burned down to a steady ember bed (around 400–500°F / 200–260°C). Slide the door into the oven opening from top to bottom. The twin-walled design seals the opening without needing latches. Common mistake: installing the door when the oven is cold or the fire is roaring. That can trap too much heat and cause the door to warp or the oven to overheat.
- 2. Adjust airflow for baking or smoking: For baking, close the door fully and use the oven's top vent to control steam. For hot-smoking, leave the door slightly ajar (a 1/4-inch gap) to allow thin smoke to escape while retaining most heat. Insert a meat probe through the cutout to track internal temperature. Checkpoint: if the oven temperature climbs above your target, crack the door open a little more. If it drops, close it fully.
- 3. Add herbs or wood chips for infused smoke: Just before closing the door, toss a small handful of fresh rosemary, thyme, or soaked wood chips onto the ember bed. Close the door immediately. The smoke will circulate inside the chamber, flavoring your food without burning the herbs. Common mistake: adding too much wood or herbs at once can create bitter smoke. Start with a teaspoon-sized amount and adjust.
