The hornet heaters are extremely easy to use. To operate your heater, plug it into the appropriate power source. If your unit is equipped with an on/off switch - turn it on to begin heating the desired area. If your heater is thermostatically controlled, nothing has to be done. The heater will cycle on and off automatically to maintain the predetermined ambient temperature.
Once the engine or desired area is warm, please remove before flight or departure, and place back into the provided canvas carrying case.
*For best results when heating aircraft - use cowl plugs and an insulating blanket.
