A broken catalytic combustor (also known as a catalytic block) can reduce your stove's efficiency and performance. In this guide, we'll walk you through identifying the issue, finding the right replacement, and safely installing a new combustor to get your stove back in top shape.
Step 1: Identify a Broken Catalytic Combustor
Signs of a Broken Combustor:
- Reduced heat output from your stove.
- Visible cracks or damage upon inspection of the combustor.
How to Inspect: Locate the combustor inside your stove and visually inspect it for damage. If the combustor is cracked, warped, or otherwise compromised, it needs to be replaced.
Step 2: Confirm Compatibility
Combustors are specific to each model of stove. To ensure compatibility, identify your stove's make and model by locating the rating plate. This is typically a small metal plate on the back of the stove, containing the brand name, model name, and serial number.
Search for your model along with "combustor" (e.g., "Defiant combustor") to find the correct part. Always check the product listing for compatibility before ordering. If you cannot locate the right part, contact us for assistance.
Step 3: Understand Usage Risks
While your stove can be used in an emergency without a combustor, this should be avoided. Operating without a combustor can damage your stove and result in poor performance. Replace the combustor as soon as possible to maintain efficiency and safety.
Step 4: Inspect Housing and Gasket
When replacing a catalytic combustor, inspect the combustor housing and gasket (also called the interam gasket, wrap, or combustor gasket). The gasket should always be replaced alongside the combustor to ensure a proper seal and optimal performance.
Step 5: Replace the Combustor
Is This a DIY Task? Yes, replacing the combustor is a straightforward DIY task. Follow these steps:
- Ensure the stove is cold before starting.
- Gather tools such as screwdrivers, a small socket set, and WD-40 to loosen hardware.
- Refer to your stove’s owner’s manual for specific instructions on accessing and replacing the combustor. If you don’t have the manual, contact us for help.
- Carefully remove the old combustor and gasket, inspect the housing, and install the new combustor and gasket.
Step 6: Warranty Information
Warranty terms for catalytic combustors vary by brand. Check the specific product listing for warranty details before purchasing. Keep all documentation for future reference.
