Outdoor GreatRoom 60" Ready-to-Finish Linear Fire Pit Base

The RTF60L-K starts where most fire pit bases end: with a genuinely solid structure. G90 marine-grade galvanized steel framing provides the skeleton, and Hardiebacker fiber cement board wraps the exterior — a combination that holds up to heat, moisture, and the general ambitions of outdoor living far better than wood-framed alternatives. At 60" long, 36" wide, and 18" tall, it's a substantial centerpiece that earns its footprint.

The aluminum top surface is already in place, and two ventilation plates (10 square inches each) come pre-installed to meet combustion airflow requirements. A control panel cut-out is pre-formed for the included VCSV-CP panel, so the fit is precise rather than improvised. The design is deliberate: less field-modification guesswork, more confidence during installation.

At the heart of the kit is the BI737 burner, part of the Crystal Fire Plus family and UL Listed for use with the VCSV-CP variable control safety valve system. The burner is rated at 80,000 BTU and is compatible with both natural gas and liquid propane — the fuel type is determined at installation, so you're not locked in at the point of purchase. The variable control means flame height can be adjusted to match the occasion, whether that's a low, ambient glow on a warm evening or a more commanding display when the temperature drops.

Fifteen pounds of clear tempered fire glass gems are included in the kit, providing immediate visual depth around the flame without requiring a separate media purchase. The transparency of the glass allows light to refract across the surface in a way that opaque media simply cannot replicate.

This is a ready-to-finish product — meaning the exterior surface is engineered to accept stone veneer, tile, stucco, or other cladding materials of your choosing. The Hardiebacker substrate is specifically designed for this purpose, giving installers and homeowners a proven, code-compatible bonding surface rather than an afterthought. The aesthetic outcome is entirely yours; the structural foundation is already handled.

Manufactured in the USA and UL Listed, the RTF60L-K is recommended for hard-piped natural gas or liquid propane installations. Professional installation is advised to ensure compliance with local gas codes and clearance requirements.
