The ETL-listed rooftop draft inducers are available in RT and RTH versions. RT models are designed for exhausting gas- or oil-heating equipment, gas fireplaces, and ovens. The units include a fan proving switch. It has several optional heater interlock controls, including the UCRT combination interlock and speed control. RTH models are designed for solid fuel fireplaces, stoves, ovens, barbeques, and general-purpose exhausting. Both versions come in two capacity ranges: from 250-750 cfm and 750-1,500 cfm. The inducers can be mounted on tile-lined chimneys or metal flues and have variable-speed motors for fine-tuning each installation. Other features include a patented auxiliary cooling system to protect the fan motor from excessive heat as well as backward inclined fan blades that repel soot buildup. During inspection or servicing, the fan assembly can be tilted away from the base plate for maximum accessibility to the chimney or vent pipe interior.
