Appalachian Phase I Damper Assembly – Early Catalytic Wood Stoves

Appalachian Phase I Damper Assembly – Early Model Catalytic Wood Stove Replacement | Pre-1989 Models

Restore the proper operation of your early-model Appalachian catalytic wood stove with this Appalachian Phase I Replacement Damper Assembly. Designed for select older Appalachian wood-burning stoves, this replacement assembly is intended to replace the original cast iron damper assembly used in compatible Phase I catalytic stove configurations.

Many early Appalachian catalytic wood stoves manufactured before 1989 used rectangular catalytic combustors. Depending on the stove model and production configuration, these appliances may use either two or four catalytic combustors. This Phase I replacement damper assembly is intended for compatible stoves using these early rectangular catalyst arrangements.

The assembly includes the main damper weldment with sliding damper plate, impingement plate, new damper rod with spring handle, installation hardware, tension pins, and a catalyst sealing blanket. This provides a convenient replacement solution when the original cast iron damper has become damaged, warped, or difficult to operate.

Important Model Fitment Note:
Appalachian manufactured several different catalytic damper assemblies and combustor configurations over the years. Model names alone may not identify the correct replacement.

Before ordering, verify that your stove uses the original Phase I cast iron damper configuration and the applicable rectangular catalytic combustors. Check the stove model, manufacturing year, catalyst quantity, catalyst dimensions, and existing damper design.

Phase I Catalytic Combustor Configurations:
Early Appalachian Phase I stoves may use one of the following arrangements:

Two-Catalyst Configuration:
• Quantity: 2 Catalytic Combustors
• Catalyst Dimensions: 1-7/8" x 6-7/8" x 2"
• Replacement Catalyst Reference: SV3400
• Catalytic Combustors Sold Separately

Four-Catalyst Configuration:
• Quantity: 2 Catalytic Combustors Measuring 1-7/8" x 6-7/8" x 2"
• Replacement Catalyst Reference: SV3400
• Quantity: 2 Catalytic Combustors Measuring 1-7/8" x 6-7/8" x 1"
• Replacement Catalyst Reference: SV3448
• Total Catalytic Combustors Required: 4
• Catalytic Combustors Sold Separately

Models Reported with Four-Catalyst Configurations:
• Appalachian Gemini GXLB – Before 1989
• Appalachian 32-BW – Select models before 1989
• Appalachian 4N1 XL Trailmaster – Select early configurations
• Appalachian 36BW – Before 1988
• Appalachian 52WXL

Important Catalyst Compatibility Note:
Some Appalachian models were produced with different catalyst arrangements. For example, certain 32-BW models use two catalysts, while other versions use four.

Always inspect your original catalytic combustors and damper assembly before ordering. Verify both the number of catalysts and their individual dimensions. Do not assume that all stoves sharing the same model name use identical catalytic components.

Replacement Catalytic Combustors – Sold Separately:
The following replacement catalyst references are associated with the early Appalachian Phase I configurations:

• SV3400 – Rectangular Catalytic Combustor, 1-7/8" x 6-7/8" x 2"
• SV3448 – Rectangular Catalytic Combustor, 1-7/8" x 6-7/8" x 1"

The number and combination of catalytic combustors required depends on the original stove configuration.

What Does the Phase I Damper Assembly Do?
The damper assembly is an important component of the catalytic combustion system in compatible Appalachian wood stoves. It helps control the intended exhaust-gas flow path during stove startup, reloading, and catalytic operation.

When operating correctly, the damper mechanism allows the stove to function according to the manufacturer's combustion and catalytic operating procedures.

Why Replace an Original Cast Iron Damper?
Older cast iron damper components can deteriorate after years of exposure to high temperatures and repeated heating and cooling cycles. Depending on their condition, original damper assemblies may become warped, cracked, difficult to operate, or unable to maintain their intended position.

Replacing a damaged original damper with the correct Phase I assembly can help restore the mechanical operation of the catalytic damper system.

Common Signs Your Damper Assembly May Need Replacement:
• Cracked or broken original cast iron damper components
• Warped or damaged damper plate
• Damper rod is bent, seized, or difficult to operate
• Damper does not open or close correctly
• Excessive wear or deterioration of internal damper components
• Damper mechanism no longer operates as intended
• Damaged or missing hardware affecting damper operation

Installation Recommendations:
• Allow the wood stove to cool completely before beginning service
• Remove ashes and debris as necessary to safely access the original damper assembly
• Document the original damper position and hardware arrangement before removal
• Carefully remove the existing cast iron damper components
• Inspect the existing mounting brackets and surrounding stove components for damage
• Verify the replacement assembly matches the original Phase I configuration
• Install the damper weldment, sliding damper plate, and impingement plate according to the applicable service instructions
• Install the supplied damper rod, spring handle, hardware, and tension pins in their proper positions
• Install the supplied catalyst sealing blanket as specified for the assembly
• Install the appropriate catalytic combustors according to the original stove configuration
• Verify proper damper movement and engagement before returning the stove to service

Important Installation Note:
The mounting brackets are NOT included with this assembly. Inspect your existing mounting brackets before ordering and verify they are suitable for reuse.

Because this damper assembly is part of the stove's combustion and exhaust system, correct installation is essential. Professional installation is recommended if you are unfamiliar with catalytic wood stove service.

Important Safety Note:
Never operate a wood-burning stove with a damaged, improperly installed, or malfunctioning damper assembly. Always follow the appliance manufacturer's operating and service instructions when replacing catalytic combustion components.
