Product Overview

The SUBURBAN 2558A SF-30FQ RV Furnace is a 30,000 BTU forced-air furnace designed to provide dependable, efficient heating for RVs, travel trailers, fifth wheels, and other recreational vehicles. Its compact form factor helps support replacement and renovation projects where reliable cabin heat is essential.

Designed for 12-volt RV electrical systems and propane operation, the SF-30FQ uses a sealed-combustion design to draw combustion air from outside and exhaust combustion gases outside the vehicle. This helps maintain comfortable interior air quality while delivering consistent heat through the RV duct system.
