US Stove Company 40292A Flue Collar
The US Stove Company flue collar is built from heavy cast iron and designed for durability in standard 6-inch installations. Known for long-standing reliability since 1869, this collar uses genuine USSC parts to ensure compatibility with other components in the system. It’s a straightforward choice for homeowners seeking a robust connection between a wood stove and a masonry or metal chimney. Installers should verify exact outlet dimensions and ensure a snug fit to minimize drafts and leaks. The cast iron construction supports repeated heating cycles and improves draw consistency when paired with a correctly sized chimney liner.
Irnyso 6″ Steel Flue Collar BM0094
Irnyso BM0094 is a 6-inch diameter single-wall steel flue collar designed for solid fuel appliances such as wood stoves. The collar uses a 24-gauge black steel construction with a black matte finish, offering a durable, affordable option for tightening connections at the masonry breech. Its slim profile makes it suitable for tight installations where space is limited. The kit’s emphasis on compatibility with standard 6-inch flue piping helps ensure a snug seal and reliable draw when installed correctly. As with any steel collar, ensure proper clearance from combustibles and follow local code requirements during installation.
Irnyso Replacement BM0096 8″ Flue Collar (2-Pack)
This 8-inch collar from Irnyso comes as a 2-pack and is designed for 24-gauge black steel single-wall pipe connections. The larger diameter is ideal for stoves with wider outlet configurations or for regions requiring increased exhaust capacity. The matte black finish helps resist corrosion and maintain a clean appearance in exposed installations. When using multiple components, verify that the inner diameter matches your stove outlet and that the collar seats evenly against the masonry or existing piping to prevent leaks and drafts.
Irnyso BM0095 7″ Flue Collar (2-Pack)
The 7-inch BM0095 collar provides a mid-range option for single-wall piping. With a 24-gauge steel construction and black matte finish, this collar is suitable for wood stove installations where space constraints or wall thickness require a compact adapter. The 7-inch size offers a balance between clearance and draw efficiency, particularly when a stove outlet is between 6 and 8 inches in diameter. As with all steel collars, ensure a clean seal against the flue and inspect for any gaps during final assembly.
Rockford Chimney Supply Draw Collar 8″
The Rockford Chimney Supply Draw Collar uses a simple, no-franct movement design to improve draft without moving parts. This 8-inch collar is suitable for situations where a passive draw aid is desirable, such as when a chimney’s natural draft is insufficient. Its completely silent operation and straightforward installation make it a practical choice for spaces with variable outside temperatures or drafts. Keep in mind that this is an aid to draft and not a replacement for proper stove height, flue sizing, or chimney condition.
AllFuel HST 6″ Black Single Wall Adapter
The AllFuel HST 6-inch adapter connects a single-wall stove pipe to a heating appliance with a 6-inch outlet. Constructed from 21-gauge steel and finished with high-temperature black paint, this collar offers enhanced durability and a neat, protective finish that resists chipping or peeling. It is designed to withstand the heat and exposure associated with wood-burning stoves, helping to sustain a durable seal at the connection point. This option is particularly suitable for retrofits or renovations where a flexible, robust adapter is needed to bridge different pipe segments.
Buying Guide: Key Purchase Considerations And Comparisons
- Diameter compatibility: Measure your stove outlet and chimney opening. Common sizes include 6″, 7″, and 8″. Choose a collar that matches or provides a practical adapter for your specific setup.
- Material and construction: Steel collars (24-gauge or similar) are affordable and flexible, while cast-iron collars offer higher durability in long-term use. Consider the environment, heat exposure, and corrosion resistance needs.
- Single-wall vs. double-wall: Most collars here are for single-wall pipe connections. Verify compatibility with your stove’s chimney system and any insert requirements.
- Finish and corrosion resistance: A black matte or powder-coated finish provides a resistant surface that helps maintain appearance and protect against rust in damp areas.
- Installation ease: Look for collars with straightforward mounting, flush seating, and compatible hardware. Some options include pack quantities for flexibility in multi-point installations.
- Draft improvement vs. direct connection: Some products are designed to improve draw passively, while others focus on a tight direct seal. Assess your chimney’s current draft and any drafts caused by exterior conditions.
- Compliance and safety: Always ensure installation adheres to local building codes and fire safety guidelines. Consider consulting a professional for complex flue configurations or large-scale renovations.
- Cost vs. longevity: While budget-friendly collars work for many setups, investing in a higher-quality collar with better heat resistance and a longer service life can reduce maintenance and replacements over time.
In summary, selecting the right flue collar involves aligning diameter, material, and installation needs with your stove and chimney. The options above provide a range of sizes and designs—from heavy cast-iron durability to versatile steel adaptors and draft aids—so homeowners can optimize performance and safety without compromising on ease of installation.
