Each system is factory-tuned to burn cleanly within ANSI Z21.11.2 and CSA certification standards, providing safe indoor comfort with remarkably realistic flame movement and glowing ember detail. Built for efficiency, these burners convert nearly all fuel energy into usable room heat while maintaining the handcrafted fire aesthetic Grand Canyon is known for.

Designed for comfort and versatility

Available in models such as the Bedrock II Vent-Free and GlowFire Lava systems, these burners pair with Grand Canyon’s premium ceramic refractory or GlowFire™ ceramic fiber logs for unmatched realism. Choose natural gas or propane and your preferred ignition—manual, safety pilot, millivolt, or ProFlame electronic remote control. Each system includes an integrated oxygen-depletion sensor (ODS) for safety, and adjustable flame control for comfort. Whether installed in a vent-free rated firebox or approved masonry fireplace with the damper closed, these burners deliver consistent, efficient heat with a true flame look.

If your installation includes a working flue and you prefer an open, decorative flame, explore our Vented Gas Burners. All Grand Canyon burners are made in the U.S.A., rigorously tested for performance, and supported by a manufacturer warranty for lasting peace of mind.

FAQs (People also ask)

What is a vent-free gas burner?

A vent-free gas burner is a heating system designed to operate safely without a chimney or vent. It uses specially engineered air-mix technology and an oxygen-depletion sensor (ODS) to ensure clean, efficient indoor combustion.

Are vent-free gas burners safe?

Yes. All Grand Canyon vent-free burners are ANSI- and CSA-certified, equipped with built-in ODS systems that automatically shut off the burner if oxygen levels fall below safe limits. Proper installation and room ventilation are required for safe operation.

Do vent-free gas burners produce heat?

Yes. Unlike vented systems, vent-free burners retain nearly all of their heat inside the room. They’re ideal for efficient zone heating while providing the look and feel of a traditional fire.

Can I use propane with a vent-free burner?

Yes. Most Grand Canyon vent-free burners are available in both natural gas (NG) and liquid propane (LP) configurations, each factory-calibrated for safe, consistent flame performance.
