Product Overview

The Dometic™ Atwood 33302 Large Heat Exchanger Service Kit is a genuine OEM service kit designed for select DFLD series RV furnaces.

The heat exchanger is one of the most critical safety components in an RV furnace. It transfers heat from the combustion chamber to the interior air supply while keeping exhaust gases completely separated from the living space. A cracked, corroded, or compromised heat exchanger can cause furnace shutdowns, poor heating performance, and unsafe operation.

This large heat exchanger service kit provides the necessary components for properly servicing and restoring compatible DFLD furnaces to safe operating condition.

Manufactured to original Dometic specifications, Part 33302 ensures proper combustion isolation, efficient heat transfer, and long-term durability.

Please Note: This is a Special Order item and typically ships within 7–14 business days.
