For more precise temperature control, this Suburban furnace steps up with a dual-stage burner that modulates heat output based on demand. Running on LP gas and sparked by direct ignition, it delivers the same 20,000 BTU output as single-stage models but with smoother, quieter operation. Side discharge directs warmth directly into your living space, and the compact 17 × 20 × 7.5-inch footprint keeps installation straightforward in tight quarters.
