Overview

The Atwood 8520 IV is a 20,000 BTU furnace heater designed for RVs and marine applications. This electronic ignition furnace operates on 12 VDC with a 4.6 amp draw and uses LP gas. It features a redesigned burner and blower assembly for more efficient and quieter operation, with increased airflow.

The furnace fits openings of 17" W x 7 1/2" H and measures 16 1/2" wide x 7 3/8" high x 18" long. It is a replacement for older models and is being superseded by the Atwood 32815 (Model AFMD20), which has approximate casing dimensions of 16 1/2" W x 7" H x 20" D.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
