The Tjernlund HS2 Gas Sidewall Power Venter Fan is a robust solution for sidewall venting, designed to save both time and money. It's particularly effective for renovations, new constructions, or replacing deteriorated chimneys. The system includes safety interlocks to ensure proper exhaust, a feature not commonly found in traditional chimneys.

Users have praised its ease of installation and compatibility with existing systems. One reviewer noted that it was a perfect replacement for a 10-year-old unit and has been functioning flawlessly for two months. The included instructions were also highlighted as being clear and helpful.

However, some users found the control board challenging to configure. Another user mentioned that while the unit itself is excellent, customer service was less than satisfactory when dealing with installation issues on older systems. Despite this, after persistence, the issue was resolved, and the unit performed well.

Overall, the Tjernlund HS2 offers great value and functionality but may require some patience when dealing with customer support or complex installations.
