摘要： Exemplary embodiments of a system and method for bimodal air control in a kettle-style grill are configured to be detachably mounted to the exterior of a kettle-styled grill such as, but not limited to, a Weber® charcoal grill. When mounted to the kettle-styled grill, a plenum-like component directs air flows to the interior of the grill's kettle via the kettle's lower body damper holes. A manually adjustable intake damper in the plenum component allows, restricts, or prevents a drawn ambient air flow into the plenum component. Separately, a forced air flow generated by a fan may also be provided into the plenum component. Adjustment of the intake damper may also adjust damper blades inside the grill's kettle. Ash that falls out of the kettle's damper holes falls through the plenum component and is captured in an ash receptacle that is removably mounted to the plenum component.

摘要： A furnace assembly comprising a non-condensing furnace with a draft inducer. The draft inducer includes a permanent magnet electrically commutated motor and a draft inducer blower fan. The motor includes a stator, a rotor, a motor cooling fan, and a controller. The rotor being rotatable relative to the stator, the fan being operatively coupled to the rotor such that rotation of the rotor causes rotation of the fan, the controller being configured to selectively operate the motor in first and second different torque ranges of the rotor, with the first and second torque range operating within a fixed percentage and within a fixed percentage of each other. The controller being configured such during normal operation, the motor is not operable at any torques between the first torque range and the second torque range except during transitionary periods.

摘要： A stack damper control apparatus for positioning a stack damper and controlling a fuel source in response to closing of a temperature sensitive switch. Limit switches comprising drop cams are coupled to the drive shaft of the damper. In response to a call for heat, a motor turns the damper, coupling a source of energy to a fuel source when the damper is open and the limit switches transfer. A relay coil is energized to hold open a switch providing a parallel energization path for the motor. When the call for heat has been met and the temperature sensitive switch opens, the relay de-energizes closing the parallel energizing path and allowing the motor to close the damper. Provision is made for a safety interlock to ensure the fuel source is not activated when the damper is closed. Provision is also made for interface to a blocked vent shutoff system.

摘要： A furnace stack damper control apparatus has a motor for connection to a stack damper to open the damper upon a call for heat by a space thermostat. The motor is driven in a closed direction by electrical energization and in an open direction by a spring return. A relay having two normally open switches and a normally closed switch is energized when a space thermostat calls for heat. The normally closed switch then opens to allow the damper motor to open the damper by the spring return. The motor has an end switch having a normally open and a normally closed circuit. The normally open circuit is used with one of the normally open switches of the relay to energize a gas valve when the damper is open. The normally closed end switch is used to provide the energization circuit for the relay by the space thermostat and the relay is maintained energized when the damper is open by the other normally open switch of the relay connected in parallel to the normally closed end switch. The circuit provides for additional safety in that normal operation of the gas valve control apparatus does not take place if the normally open or normally closed end switches stick in either position.

摘要： A flue damper is rotated 360.degree. in a predetermined direction in 90.degree. increments to be selectively opened and closed in 90.degree. increments. The incremental rotation is accomplished by a motor driven timing mechanism with power to the motor being controlled by the timing mechanism and a solid state switching means selectively energizing and deenergizing the motor.

摘要： An electric motor driven operator and control for dampers of the gravity return type, such as used in chimney flues for fireplaces. The operator comprises an electric motor-gear speed reduction unit for driving a crank arm which engages with a pivoted member in an elongated slot in the latter. In each revolution of the output shaft of the driving unit the pivoted member opens the damper in the first half revolution, and then allows it to close in the remaining half revolution. The control comprises a two position selector switch, and limit switch operable in accordance with the motor shaft position to cause the motor to stop when the damper is in full open position, or when in completely closed position. Indicating lights are provided to indicate when the damper is in open position, and when the temperature in the region of the damper operator exceeds a predetermined high limit.
