Dickinson Heaters – 3″ Heatex Map 15 | 00-HEA3

3-Inch Heatex Chimney Heat Exchanger

The Dickinson 00-HEA3 Heatex recovers heat from a compatible stove or heater flue and uses a 12 V fan to move warmed cabin air through ducting. This is the 3-inch chimney version.

Key Features

• Stainless-steel construction.
• Fits the specified 3-inch flue arrangement.
• 12 V fan-assisted warm-air circulation.
• Warm-air ducting is required separately.

Product Compatibility

Intended for the compatible Dickinson and Sig Marine oil-stove/heater installations described in the manual. Confirm the appliance, flue size and available draft before adding it.

Installation Notes

Check compatibility with the appliance and chimney layout in Dickinson’s instructions. Maintain all combustion-air and flue clearances, and verify adequate chimney draft. Start the Heatex fan only after the stove or heater has reached operating temperature.

Parts Desk Insight

Recovering more flue heat can reduce chimney draft, particularly on a short stack. Assess the entire chimney installation rather than choosing a Heatex by pipe diameter alone.
