Understanding Legacy Models: F2400M, F2404M, and F2403M
The F2400M, F2404M, and F2403M are often confused with the F2450 due to their shared medium size and non-catalytic design. Here’s how they relate:
- F2400M: The original Classic Medium Wood Stove, with a 2.3 cu. ft. firebox and 75,000 BTU/hr output. It’s the predecessor to the F2450, using identical parts (e.g., 850-141 black door, 846-302 glass).
- F2404M: A variant of the F2400M, likely a regional or legacy SKU, with the same parts (e.g., 020-363 heat shield, 846-973 door handle).
- F2403M: Likely a typo or misreference for F2400M/F2404M, as it lacks documentation. Assume compatibility with F2400M/F2450 parts unless confirmed otherwise.
For parts, the F2450 page covers all components for F2400M, F2404M, and F2403M, ensuring seamless replacements.
Key Differences Between F-Series Models
| Model | Size | Technology | Heat Output | Efficiency | Best For |
|---|---|---|---|---|---|
| F1150 | Small | Non-Catalytic | 55,000 BTU | 77% | Small spaces |
| F1500 | Small | Catalytic | 60,000 BTU | 86% | Efficient small heating |
| F2450 | Medium | Non-Catalytic | 75,000 BTU | 77% | Medium homes, legacy models |
| F2500 | Medium | Hybrid | 78,000 BTU | 82% | Medium, long burns |
| F3500 | Large | Catalytic | 85,000 BTU | 84% | Large homes |
| F5200 | X-Large | Hybrid | 95,000 BTU | 81% | Maximum heating |
- Technology: Non-catalytic (F1150, F2450) for simplicity; catalytic (F1500, F3500) or hybrid (F2500, F5200) for higher efficiency and lower emissions.
- Size and Output: Ranges from small (F1150, F1500) to extra-large (F5200), matching diverse home sizes.
- Legacy Integration: F2400M/F2404M align with F2450; F2403M is speculative but likely equivalent.
