Unidanho Flame Broiler Kit for Pit Boss Pellet Grills — Stainless Steel Bottom Plate & Slide Cover (15.5" x 32" / 15.5" x 10")

Unidanho's Flame Broiler Kit replaces the worn bottom plate and slide cover on compatible Pit Boss pellet grills to restore flame control and even heat distribution for better searing.

If your Pit Boss smoker or pellet grill is showing hot spots, ash buildup under the broiler, or a bent or missing slide cover, this replacement kit makes it straightforward to bring performance back without buying a whole new grill. Designed as a direct-fit option for many Pit Boss models, the kit includes a heavy-duty stainless-steel bottom plate and a matching slide cover sized to the original specifications so you can re-create the original flame path and protect the firebox.

Which models does this broiler kit work with?

The Unidanho Flame Broiler Kit is engineered to fit a broad range of Pit Boss pellet grills and smokers that use the PB1100-style broiler parts. It covers several popular model families where the original part numbers match the listed dimensions and design. However, it is not compatible with Competition Series or specific Sportsman 1100 variants, so double-check model fit before ordering.

• Compatible with Pit Boss Pro Series 1100, Austin XL-Onyx, Navigator 1150, PB1000, PB1150, PB1600 families
• Replaces part numbers: 1100PS1-5, 1100PS1-4, PB1100PS1-W007, PB1100PS1-005, and 60547
• Not compatible with Competition Series, Sportsman 1100 PSC variants
• Measure 15.5" W x 32" L for the bottom plate and 15.5" W x 10" L for the slide cover

How does the stainless-steel construction improve grilling?

The kit uses thick, premium-grade stainless steel to resist warping, rust, and abrasion from repeated heating cycles. A solid, gap-free mating between the broiler plate and slide cover restores consistent flame exposure across the cooking surface, reducing cold zones and ash migration under the grates. That creates a more even sear and makes maintenance easier.

• Heavy-duty stainless resists heat deformation and corrosion
• No air gap between plate and slider for improved flame control
• Less ash buildup beneath the broiler, simpler clean-up
• Designed to re-establish even heat distribution and searing

What’s involved in installing the Unidanho flame broiler?

Installation is straightforward for anyone comfortable with light grill maintenance: remove the old plate and slide, position the new bottom plate, and slide in the new cover. You may need a screwdriver to secure the flame broiler lever bucket if your model uses one; the lever itself is not included. The kit is intended to match factory geometry so it slips into place without major modification on compatible models.

• Remove old broiler parts and clean the surrounding area first
• Slide in the 15.5" x 32" bottom plate, then install the 15.5" x 10" slide cover
• Screw in the lever bucket if required (screwdriver needed)
• No welding or cutting required for compatible grills

Will this kit change the way my grill cooks?

Replacing a damaged or corroded broiler bottom plate and slide restores the intended flame path and prevents uneven hotspots, so you should notice more consistent heat and cleaner searing. The kit is a replacement part, not a performance upgrade, but restoring original geometry often improves results compared to a worn or missing plate. Keep in mind model-specific variables—grate condition, pellet type, and venting—also affect outcomes.

• Restores original flame distribution for more uniform cooking
• Helps eliminate localized hot or cold spots on the grate
• Reduces ash intrusion into the broiler area for cleaner flavor
• Maintains factory airflow when correctly installed

Who is this for: Home grill owners and backyard smokers who own compatible Pit Boss pellet grills and need a durable, cost-effective replacement for a warped, rusted, or missing flame broiler bottom plate and slide cover. It’s aimed at users who want to restore factory heat distribution and flame control without replacing the entire grill, and who are comfortable performing simple part swaps.
