Dometic | Small Furance | DFSD20111 | 18,000 BTU | Doored

The Dometic DFSD20111 Mojave Furnace is a powerful, compact 18,000 BTU forced-air propane heater designed for easy installation and quiet comfort. Featuring a newly engineered heat exchanger with seamless tubular construction and radius bends, it delivers improved airflow and reduced noise—making it perfect for van conversions, truck campers, small trailers, and ice houses.

• Quiet Operation – Radius tubing minimizes turbulence for a smoother, quieter airflow
• Efficient Heat Distribution – One-piece heat exchanger maximizes air movement and output
• Compact Design – Ideal for tight spaces without sacrificing performance
• Customizable Ducting – Offers the most ducting options in its class

Note: The furnace housing is constructed from lightweight, pliable steel to minimize overall shipping weight. As a result, minor cosmetic bends may occasionally occur during transit. These bends do not impact the unit’s performance and can typically be corrected by gently reshaping the housing with a pair of pliers prior to installation.

*This furnace may not be a "direct" replacement. Depending on your application and what your current model furnace is, there COULD be modifications needed to replace your existing furnace with a new furnace.
