Description
The Scandia 40,000 BTU Natural Gas sauna heater delivers sealed-combustion performance and fast, even heat for rooms up to 616 cu ft. Built in the USA with a #304 stainless exterior and #321 stainless internal chamber, this floor-mounted unit provides the classic feel of a large rock tray while keeping combustion air and flue gases outside the sauna room for cleaner operation.
Choose the venting that fits your layout: horizontal/direct vent (Model 240) with a flue cap or vertical vent (Model 245) with a draft hood. Control is straightforward via the included mechanical “G” wall control with a 60-minute timer; a 24-hour timer is available for commercial applications. Typical performance in a properly built 7-ft-ceiling room reaches ~170–185°F in about 30–60 minutes, then cycles to maintain temperature.
Installation is supported with a galvanized through-wall back panel, stainless internal wall flashing, and the appropriate vent termination (cap or hood). Gas supply is regulated to typical 3.5" W.C. natural-gas pressure (acceptable supply 1/8–1/2 psi with proper regulation). The compact chassis—18.5" W x 21" D x 28" H—fits neatly beneath benching while preserving strong stone mass for stable, enveloping heat.
Key build details include an all-stainless construction, sealed-combustion architecture, high-density stones (included), and clear guidance on thermostat probe placement and guard rail requirements for safe operation. Whether specified for residential or light-commercial projects, the 40K NG combines gas efficiency with the soft löyly enthusiasts expect from a traditional rock-bed heater.
Backed by Scandia’s limited residential warranty, the 40K BTU Natural Gas model is a solid, specification-driven choice for builders and homeowners who want reliable performance, flexible venting, and simple, familiar controls—without electric elements.
