The Tjernlund HS2 Gas Sidewall Power Venter Fan is a robust solution for sidewall venting, designed to save time and money in various settings, from renovations to new constructions. It's particularly effective for replacing deteriorated chimneys and is compatible with Tjernlund VH Series Vent Hood Terminations.

Users have praised its performance, noting that it works excellently as a direct replacement for older models. The included instructions are clear, making installation straightforward. However, some users found the control board challenging to configure.

Installation experiences vary; some users report a smooth process, especially when replacing identical units. Others faced wiring issues, particularly with the HS1 control, which was described as over-engineered. Despite these challenges, the unit's safety features, such as the reed pressure switch and proven safety interlocks, ensure proper exhaust and add a layer of security not found in conventional chimneys.

Customer service experiences were mixed. While some users found tech support helpful and knowledgeable, others encountered unhelpful and rude representatives. This inconsistency in customer service quality is a notable drawback.

Overall, the Tjernlund HS2 offers great value and functionality for those looking to upgrade their venting systems without the need for costly chimney installations or replacements. It's an excellent choice for modern homes seeking efficient and safe venting solutions.
