A worn or missing flame deflector can leave your gas grill’s burners exposed to grease and direct flame, while making heat less even across the cooking surface. These replacement parts—also called heat plates, heat tents, or burner covers—sit above the burners to shield them and help spread heat. The right choice depends on how many plates you need, their material, and whether their dimensions match your grill. Measure your existing parts before ordering, since “universal” does not mean a guaranteed fit.

Our Picks: Best Flame Deflector For Gas Grill reviews
1. Adviace Adjustable Porcelain Heat Plates: A Flexible Three-Pack
This Adviace set includes three telescoping heat plates, each 3.75 inches wide and adjustable from 11.75 to 21 inches long. The porcelain-coated steel construction is listed as 1.2 mm thick, and the set comes with stainless steel bolts and wing nuts for assembly.
The plates are designed to shield burner tubes from direct exposure and help spread heat toward the cooking grates. The adjustable length gives you more flexibility than a fixed-size plate, but the width and mounting arrangement still need to suit your grill. The description names several compatible grill brands and models, though checking your own grill’s measurements is the safer step.
Compared with the four- and five-piece options here, this is a straightforward pick if you need three replacements rather than a complete set for a grill with more burners. Its main trade-off is that porcelain-coated steel may not suit shoppers who specifically want stainless steel.
Pros:
- Three plates are included.
- Adjusts from 11.75 to 21 inches long.
- Thick, 1.2 mm porcelain-coated steel construction.
- Includes stainless steel bolts and wing nuts.
Cons:
- Only three plates are included, which may not cover every grill.
- Requires careful measurement to confirm fit.
Verdict: Choose this set if your grill needs three adjustable porcelain-coated heat plates and the measurements match your originals.
2. Unicook Adjustable Heat Plates: A Four-Pack in Porcelain-Coated Steel
Unicook’s set provides four adjustable plates made from 1.2 mm porcelain-coated steel. Each plate is 3.75 inches wide and can extend from 11.75 to 21 inches in its standard orientation. The description notes a shorter maximum extension if a plate is installed in reverse, so follow the intended assembly direction and compare the fit with your old parts.
The plates are meant to protect burners from direct flame and help distribute heat. Stainless steel M5 bolts and wing nuts are included. The product is described as fitting many outdoor gas grills, but its own guidance emphasizes measuring the mounting slot and original heat plates before buying.
Its four-piece count may be a better match than the three-piece Adviace set for grills that use four heat tents. On the other hand, it is not the right choice if your grill needs a different number of plates or a stainless-steel construction. Unicook also identifies a separate stainless-steel version, which is not the product reviewed here.
Pros:
- Four plates are included.
- Adjustable length up to 21 inches in the standard orientation.
- 1.2 mm porcelain-coated steel construction.
- Includes stainless steel bolts and wing nuts.
Cons:
- Reverse installation reduces the stated maximum length.
- Fit depends on your grill’s dimensions and mounting slots.
Verdict: This is a practical option when you need four porcelain-coated plates and your grill’s dimensions fall within the stated range.
3. Adviace Stainless Steel Heat Plates: Adjustable and Made for Easy Cleaning
This Adviace option is made from 1.2 mm stainless steel and has an adjustable length of 11.75 to 21 inches. The description also gives a shorter range for its alternate assembly orientation. It includes eight screws and offers two assembly options, which may help with different grill layouts.
Like other heat tents, these plates sit above the burners to reduce direct flame exposure and distribute heat toward the grates. The listing describes an enamel production process intended to make the plates easier to clean when grease collects. Since the product is identified as stainless steel, check the seller’s detailed specifications if the surface finish is a key factor in your decision.
Compared with the porcelain-coated sets, this model is aimed at shoppers who prefer stainless steel. The supplied information does not state how many plates are in the package, so verify the quantity on the listing before ordering. That detail matters if you plan to replace every heat deflector at once.
Pros:
- Made from 1.2 mm stainless steel.
- Adjustable up to 21 inches in one assembly orientation.
- Offers two assembly options.
- Includes screws for assembly.
Cons:
- The package quantity is not specified in the supplied product details.
- The alternate assembly orientation has a shorter stated maximum length.
Verdict: Consider this set if stainless steel and alternate assembly options are priorities, but confirm the number of plates and exact fit before purchasing.
4. Hiorucet Stainless Heat Plates: A Five-Piece Set for Larger Replacements
Hiorucet’s package includes five adjustable stainless steel heat plates, along with bolts and nuts. Each plate is 3.75 inches wide and can extend to 21 inches. The listing gives several grill model references, including specific Nexgrill, Dyna-Glo, Members Mark, Brinkmann, and Char-Broil models.
The five-piece quantity makes this set stand out from the other choices in this guide. It may suit a grill that needs five burner covers, but the number of plates alone does not confirm compatibility. Check both the individual plate dimensions and your grill’s mounting points against the listed model information.
This is the only option in this lineup that clearly specifies a five-plate stainless-steel set. If your grill needs fewer plates, buying a larger pack may be unnecessary. Its product details list multiple model numbers, but the list should be treated as a starting point rather than a substitute for checking measurements.
Pros:
- Five heat plates are included.
- Stainless steel construction.
- Each plate adjusts up to 21 inches.
- Bolts and nuts are included.
Cons:
- The five-piece pack may be more than some grills need.
- Model lists do not replace checking the plate and mounting dimensions.
Verdict: Choose this set if your grill needs five stainless-steel deflectors and the listed dimensions and mounting points match your existing parts.
5. EmberFeast Porcelain Heat Plates: A Four-Pack with Hand-Tightened Hardware
EmberFeast includes four heat plates made from 1.2 mm porcelain-coated steel. Each is 3.75 inches wide and adjusts from 13.39 to 21 inches long. That shorter minimum length is an important difference from the other adjustable options in this guide, which start at 11.75 inches.
The plates are designed to shield burners from grease drips and direct flame while spreading heat across the cooking surface. The set comes with stainless steel 304 M5 bolts and wing nuts, and the listing describes installation and removal as possible by hand without tools. Measure your original deflectors carefully, especially if they are shorter than 13.39 inches.
Compared with the Unicook four-pack, EmberFeast offers a higher minimum length and hand-tightened hardware. It may be a convenient fit for grills whose original plates fall in its stated range, but the adjustment span is less flexible at the shorter end.
Pros:
- Four plates are included.
- 1.2 mm porcelain-coated steel construction.
- Includes stainless steel 304 bolts and wing nuts.
- Hardware is designed for hand installation.
Cons:
- Its 13.39-inch minimum is longer than the other listed adjustable options.
- Fit should be confirmed by measuring the original plates before ordering.
Verdict: This is a good candidate for a four-plate replacement when your original deflectors are at least 13.39 inches long and you want hand-tightened hardware.
How to Choose a Flame Deflector for a Gas Grill
Measure the Original Plates First
Measure each existing heat deflector from end to end and across its width. Also check the mounting points and the opening or slot where the plate sits. Adjustable products still have a minimum and maximum length, and a plate that fits the length may not line up with your grill’s supports. Compare the measurements with the product details before ordering.
Match the Number of Plates to Your Grill
Count the deflectors your grill uses and check how many are included in the replacement package. The products here range from three plates to five, while the supplied details for one set do not state a package quantity. Replacing only one damaged plate may call for a different pack than replacing the full set.
Choose a Material That Suits Your Priorities
Several options use porcelain-coated steel, while two are identified as stainless steel. The listed porcelain-coated plates are 1.2 mm thick; the stainless options are also described as 1.2 mm thick. Compare the stated material and finish rather than assuming that every plate advertised as “heavy duty” will perform the same way.
Check the Adjustment Range and Assembly Direction
Most of these plates extend from 11.75 to 21 inches, but some have a shorter range when assembled in a different orientation. EmberFeast starts at 13.39 inches, so it may not fit a shorter original plate. Follow the assembly directions and confirm that the version you plan to install reaches the needed length.
Use Model Numbers as a Cross-Check
Product listings may name compatible grill brands or model numbers, but model variations can make fit less straightforward than a brand name suggests. Find your grill’s model information and compare it with the listed references. Then check the measurements of the original part, since dimensions and mounting position are especially useful for confirming a replacement.
Consider the Included Hardware and Installation
These products include bolts, screws, or wing nuts, but the exact hardware differs. EmberFeast describes hand installation with wing nuts, while the other listings also specify included fasteners. Check that the package has the hardware you need and follow the grill and product instructions during installation.
FAQs
What does a flame deflector do on a gas grill?
A flame deflector, also called a heat plate or heat tent, sits above the burner. It helps protect the burner from grease and direct exposure to flame, and it is designed to distribute heat toward the cooking grates.
Are universal gas grill heat plates guaranteed to fit?
No. “Universal” generally indicates that a product is designed for a range of grills, not every grill. Check the plate dimensions, adjustment range, mounting points, and any listed model numbers before buying.
How do I know how many heat plates to order?
Open your grill and count the existing plates. If you are replacing the full set, match the package quantity to the number of parts your grill uses. If you are replacing only damaged plates, check whether the product is sold in a pack that makes sense for your needs.
Which is better: porcelain-coated steel or stainless steel?
Neither material is automatically the best choice for every grill. The products here offer both, and the listings describe their construction differently. Choose based on your preferred material, the exact fit, and the specifications for the replacement part.
Can I install adjustable heat plates in either direction?
Some products allow more than one assembly orientation, but the usable length can change with the orientation. Check the instructions and stated adjustment range for the specific product rather than assuming both arrangements reach the same length.
Do I need tools to install these heat deflectors?
Installation depends on the product and its hardware. EmberFeast describes hand installation with wing nuts, while other sets include bolts, screws, or nuts. Check the included parts and the installation directions before beginning.
Final Recommendation
For a simple three-plate replacement, the Adviace porcelain set offers a clear quantity and an adjustment range starting at 11.75 inches. If you need four plates, Unicook provides a similar range in porcelain-coated steel, while Hiorucet is the clearly specified five-piece stainless option. The Adviace stainless set may appeal to shoppers prioritizing that material, but confirm its package quantity. Whichever you choose, measure your old parts and mounting points first; fit matters more than a broad compatibility claim.
