Abstract: A portable heater includes a housing having an air inlet and an air outlet, one or more burners housing within the housing and configured to heat air passing through the housing from the air inlet to the air outlet, and a duct positioned in a storage compartment of the housing. The duct includes a first end coupled to the storage compartment and a second end extendable from the housing when a door of the storage compartment is in an open position.

Abstract: A portable industrial heater including a housing having an air inlet and an air outlet, one or more burners housed within the housing and configured to heat air passing through the housing from the air inlet to the air outlet, and a generator selectively providing power to the one or more burners. The air inlet and the air outlet are positioned on a same side of the housing.

Abstract: Outdoor power equipment includes a frame supported by a plurality of wheels and an air heating system. The air heating system includes an air inlet, an air outlet, a heating device configured to heat the air between the air inlet and the air outlet, and an adjustable duct connector fixedly coupled to at least one of the air inlet and the air outlet. The adjustable duct connector includes a base plate, a ring arm slidably coupled to the base plate, and a handle rotatably coupled to the base plate and the ring arm. Rotation of the handle selectively transitions the ring arm between a first position proximate the handle and a second position arranged further from the handle. The adjustable duct connector further includes a locking mechanism configured to secure the ring arm in the first position and the second position.
