A temperature sensitive duty cycling control switch is mounted to a forced air ductless gas or oil heater by a special mounting bracket. The bracket attaches to the front of the heater in the path of the heated airflow. The mounting device is basically a tapered conduit or duct which is held at a distance from the heater so that it does not unduly obstruct the airflow and is tapered to concentrate air generated by the heater onto a plate mounted in front of the duct. The duty cycling control switch is then mounted to this plate and responds to the temperature of the plate. This enables the cycling of the heater burner while the fan continues to operate. |
