What’s the best approach for installing wood stove pipes in tight spaces?

Choosing the Right Pipe

When installing wood stove pipes in tight spaces, the type of pipe you choose is crucial. Flexible pipes, such as stainless steel or aluminized steel flex pipes, can be bent to fit through narrow openings, making them ideal for tight spaces. Insulated pipes, which have a thermal break between the inner and outer walls, can also be used to reduce heat loss and improve efficiency. For larger installations, consider using 6-inch or 8-inch insulated double-wall chimney pipes, which offer better heat containment and are more suitable for longer runs.

Positioning the Vent

Positioning the chimney or vent directly above the stove is critical to minimize horizontal runs and ensure safe operation. Aim to keep the horizontal run as short as possible, ideally less than 24 inches, to prevent creosote buildup and improve draft. This can be achieved by installing the stove in a corner or against a wall, allowing the vent to extend straight up. If this is not possible, consider using a 45-degree or 90-degree bend to shorten the horizontal run and improve airflow.
