COMVIEE Heat Baffle Diffuser Replacement for Traeger Pro/ Ironwood/ Timberline — 11x6x5in Aluminum-Coated Steel, Warp-Resistant

COMVIEE Heavy Duty Heat Baffle Diffuser is a direct-fit replacement heat deflector designed to restore even, stable heat distribution in Traeger Pro 575/780, Ironwood 650/885 and Timberline 850/1300 pellet grills.

If your Traeger D2 pellet grill is producing uneven heat, frequent flare-ups, or you see visible wear on the original heat baffle, this COMVIEE aluminum-coated steel diffuser offers a durable, dimension-compatible replacement. Manufactured to match replacement part numbers KIT0450 / BCA1268, the part measures 11" L x 6" W x 5" H and was engineered to resist warping and maintain consistent performance under high temperatures. Installing a new heat diffuser is a quick maintenance step that can prolong grill life and improve cooking consistency without changing grill settings.

How does this diffuser improve my grill's cooking consistency?

The COMVIEE heat baffle evens out the flame and smoke flow across the cooking chamber so hotspots and cold zones are reduced. Its unique diffuser surface redistributes heat and promotes steadier charcoal or pellet burn patterns, helping food cook more evenly.

• Aluminium-coated steel construction prevents warping at high temps.
• Diffuser shape redirects hot air and smoke for uniform heat.
• Improved combustion stability reduces temperature swings.

Will this part fit my Traeger model and how do I confirm fit?

This replacement is made to be compatible with Traeger Pro 575 and 780, Ironwood 650 and 885, and Timberline 850 and 1300 D2 pellet grills, matching common KIT0450 / BCA1268 dimensions. Because grill models can vary by year and aftermarket mods, measure your original baffle before ordering to confirm the 11" x 6" x 5" size will work.

• Part numbers referenced: KIT0450, BCA1268.
• Compare your current baffle dimensions to 11" L x 6" W x 5" H.
• Contact support if your grill has non-standard modifications.

How durable and heat-safe is this COMVIEE replacement?

Constructed from aluminium-coated steel, the diffuser is designed for reliable long-term use under repeated high-heat cycles without significant deformation. The material choice balances thermal resistance with structural strength, ensuring the baffle supports continued efficient operation of the grill.

• Aluminium coating resists corrosion and heat stress.
• High weight-bearing capacity maintains placement under loads.
• Manufactured for repeated temperature cycles without warping.

How easy is installation and what maintenance is required?

Replacing the diffuser is typically a simple swap: remove the old, worn baffle and insert the COMVIEE unit in the same orientation. Routine cleaning of ash and grease deposits extends the part’s life and preserves even heat flow.

• Simple hand tools or no tools in most grills for removal/replace.
• Wipe or brush off ash and grease after cool-downs for best performance.
• Inspect annually for heavy corrosion or warping to decide on replacement.

Who this is for: This replacement diffuser is aimed at Traeger D2 pellet grill owners—particularly those with Pro 575/780, Ironwood 650/885, or Timberline 850/1300 models—who need a durable, dimension-matching heat deflector to restore consistent cooking temperatures. It’s suitable for home grillers who perform basic maintenance and want a long-lasting, no-fuss part that improves heat distribution and helps maintain their grill’s cooking performance.
