Seasoned grill hobbyists who love tweaking temperature curves will appreciate the measurable airflow boost and the ability to fine‑tune the draft by adjusting the cap.
Best for Professional Shops
Small catering operations that run multiple grills nightly can rely on the chimney’s durability and consistent heat management to maintain menu quality.
ABSOLUTELY NOT RECOMMENDED FOR
- Owners of non‑pellet grills (charcoal, gas, electric).
- Grill owners with very low clearance under the lid—this chimney adds ~2 inches of height.
- Those seeking a feather‑light accessory for ultra‑portable setups.
Frequently Asked Questions
- Will the chimney work on my older Traeger model? Yes, as long as the bolt spacing matches 4.5 inches. Older models often have this spacing; verify by measuring the existing mounting holes.
- Do I need to replace the gasket each season? The heat‑resistant pipe gasket is rated for at least 200 hours of continuous use. Most users replace it only when visible wear appears.
- Can I use the chimney with a liquid‑smoke injector? Absolutely. The increased airflow helps disperse liquid smoke more evenly without causing flare‑ups.
- Is the black coating safe for food contact? The powder coating is food‑grade and fully cured; it does not leach chemicals at grilling temperatures.
- How does the chimney affect pellet consumption? Airflow improvement can lead to a modest 5‑10% reduction in pellet usage because the fire burns more efficiently.
- Will the chimney fit a Pit Boss 700FB? Yes, the 4.5‑inch bolt distance aligns with the 700FB’s mounting points.
- Do I need to adjust my grill’s temperature settings after installation? Most users find the grill holds temperature better, allowing them to set the desired temp and trust the system to maintain it.
- Is there any maintenance required? Periodic cleaning of ash from the opening and a quick visual check of the gasket for cracks are sufficient.
