Outdoor GreatRoom 40" See-Through Linear Ready-to-Finish Gas Fireplace

The Outdoor GreatRoom Company RSTL-40MLP is a 40-inch see-through linear gas fireplace built for builders, designers, and homeowners who want to do the finish work themselves — without compromising on the structural integrity underneath. The enclosure is constructed from HardieBacker fiber cement board over G90 marine-grade galvanized steel framing, which is a considerably more serious foundation than the word "ready-to-finish" might suggest.

At the heart of the unit is the BI737 Crystal Fire Plus burner, rated at 80,000 BTU. The viewing area measures 40 inches wide by 20 inches tall, and because this is a genuine see-through design, the flame is visible from both sides — useful for open-concept spaces where a wall divides two rooms without visually closing them off. The overall unit dimensions are 72 inches wide, 48 inches tall, and 18 inches deep, with a total shipping weight of 213 lbs, so plan your installation accordingly.

The interior opening is lined in #304 stainless steel, which handles the thermal demands of a high-output burner without the corrosion concerns that come with lesser materials. Glass wind guard panels are included, pre-installed vents come standard, and the manual ignition controls are straightforward to operate. For installations where you want remote or timer-based operation, external controls are available separately.

This unit ships configured for liquid propane, and a natural gas conversion kit is included in the box — making it compatible with either fuel type depending on your installation. A hard-pipe connection is recommended regardless of fuel choice. One genuinely useful detail: the base access door is sized to accommodate a standard 20 lb propane tank, keeping the supply source tidy and out of sight for LP installations.

Fire media — 30 lbs are specified for this unit — is sold separately, giving you the flexibility to choose the look that suits your design. The fireplace is compatible with Outdoor GreatRoom's broader line of fire media and external control accessories. If you're working with combustible framing materials, the companion standoff model (RSTL-40-SO) is available for over-framing applications.

Made in the USA and UL Listed. The RSTL-40MLP is the kind of product that does the unglamorous structural work so the finished installation gets all the credit.
