    Inline Flue-Gas Exhausters

    Increase airflow through exhaust duct to improve furnace performance. Create a cutout in your duct, insert the blower wheel, and mount the housing to the duct. All have an open dripproof motor enclosure for relatively clean, dry, indoor locations. They cannot be used for sidewall venting applications.
    Pressure Switches—Optional pressure switch (sold separately) prevents furnace from firing if exhausters fail.

    Wall-Vent Flue-Gas Exhausters

    Often used for electric-to-gas conversions and renovations, these exhausters allow gas- or oil-fired equipment to be vented through a sidewall rather than a chimney. A thermostat signal starts the exhauster and a sensor ensures proper draft prior to operation. Exhausters have an open dripproof motor enclosure for relatively clean, dry, indoor locations. Use a reducer to vent through ducts with diameters up to 2" wider than the exhauster.
    Flue-Gas Exhauster Hoods—A flue-gas exhauster hood (sold separately) is required for the exterior of the sidewall.
