Description
National Chimney offers a unique insert adapter that enables both front-to-back and side-to-side adjustments within the firebox. Its two-piece design allows for easy sliding to adjust the center-to-center distance of the collars, accommodating a horizontal offset from 0” to 9” without needing extra clearance for elbows.
The top collar can accept either OD flex liner or rigid pipe, and it can also accept ID pipe when used with a coupler. The bottom collar is compatible with most stoves requiring a crimped connection and can be attached with screws or rivets, similar to most liners or pipes.
