Product Information Power Venter TDF 620/685 Use The TDF Power Venter are intended for use as a true in-line draft inducer. It can be installed in-line in the vertical or horizontal section of a chimney or stack. It is specifically designed for applications where reliable and efficient operation, low noise level, low energy consumption, variable speed and compact design are of utmost importance. The TDF is for use with condensing and noncondensing appliances operating where flue gas temperatures do not exceed 650°F (344°C) for intermittent operation and 575oF (302oC) for continuous operation. Typical uses are: mechanical venting of gas-fired or oil-fired boilers and water heaters. For indoor or outdoor installation. Description The TDF Power Venter is an efficient, hightemperature ventilator with backward-inclined impeller. It can be installed horizontally or vertically in a chimney system. The fan housing is made of stainless steel and equipped with an energy-efficient, totally enclosed, variable speed motor, which is mounted outside the air stream. The motor and impeller is a complete assembly (drive unit) that can be removed from the fan housing without removing the fan from the stack system. The stack connections are of the flanged connection type and fit most commercial prefabricated chimney systems. Slip connection fittings are available. The fan is typically installed hung from ceiling mounting brackets to support the weight. The complete drive unit (motor, impeller and mounting plates) can be removed from the fan without the need for removing the housing. The TDF model is approved for temperatures up to 650°F (340°C) and is a component in the CASI, Chimney Automation System. Specifications are subject to change without notice.
