The Tjernlund HS3 Gas Sidewall Power Venter Fan is used for side wall venting commercial natural gas or LP fired equipment such as boilers, water heaters, and unit heaters. This model features a UC1 Universal Control and a diaphragm Fan Proving Switch for safety interlock, which shuts down heating equipment if venting malfunctions occur.
Side wall venting saves on costly materials and labor, especially on tall building runs. Proven safety interlocks ensure proper exhaust, a feature not always present in conventional chimneys.
