GASPRO 18 x 6 in Stainless Steel H Gas Fireplace Burner — 90,000 BTU, Non-Whistle Durable Design

The GASPRO 18 x 6 inch H-shaped stainless steel gas burner delivers a durable, non-whistling flame source for fireplaces, fire pits and fire tables, ready to run on propane or natural gas.

Designed as a direct-replacement or upgrade burner, this H burner combines corrosion-resistant 304-series stainless steel with precision-drilled ports to produce even, efficient flames while resisting warping and rust. At 18" by 6", the kit suits medium-length fireplace openings and many rectangular fire pit bowls. It’s rated up to 90,000 BTU and built with thicker metal than many competitors to extend service life in indoor or outdoor installations.

How does the GASPRO H burner prevent the common whistle sound?

The GASPRO burner itself uses machine-drilled ports rather than punched holes, which reduces turbulent gas flow that causes whistling. For complete silent operation, pair the burner with a whistle-free connection kit that uses brass fittings and a damper-style C-clamp to smooth gas delivery.

• Drilled ports create steady, laminar gas flow for quiet flames
• Recommended whistle-free connection kit minimizes pressure noise
• No punched or uneven holes that amplify high-frequency whistle sounds

Will this burner fit my fireplace or fire pit and how hard is installation?

The 18" x 6" H configuration fits many medium rectangular fire boxes and fire pit pans. Installation is designed to be quick—most DIYers can complete it in about 15 minutes with standard hand tools. Always follow local codes and shut off gas before swapping components.

• Overall size: 18 inches wide by 6 inches deep to match common openings
• Simple bolt/clamp mounting compatible with standard setups
• Works with both propane and natural gas systems (check orifice sizing)

What materials and performance should I expect from this burner?

The GASPRO H burner is fabricated from heavy 304-series stainless steel that is significantly thicker than many market alternatives, offering stronger resistance to heat warping and corrosion. It is machine-made to maintain consistent port sizes and is rated for up to 90,000 BTU, providing robust flame height and heat output when matched to the correct gas type and regulator.

• Extra-thick 304 stainless steel — built to outlast thinner burners
• Machine-drilled ports for reliable, even flame distribution
• Rated up to 90,000 BTU for strong flame presence

Can I use it outdoors and how do I maintain it?

This burner is suitable for both indoor fireplaces and outdoor fire pits or tables when installed following local safety codes. Its stainless finish resists rust, but routine checks for debris or blockages and occasional cleaning will extend performance.

• Appropriate for indoor and outdoor use with proper installation
• Simple maintenance: brush ports and clear debris periodically
• Corrosion-resistant finish reduces long-term upkeep

Who is this for: Homeowners and contractors looking for a reliable mid-size H-style burner that reduces whistle noise, provides strong heat output and resists corrosion. It’s a good match for anyone replacing a worn or underperforming burner in a medium rectangular fireplace, retrofit fire pit bowl, or fire table who wants a durable stainless steel upgrade and faster, quieter installation.
