Honda generators are designed to operate in cold weather. However, there are some coldweather conditions where it is possible for condensation to collect and freeze inside the crankcase breather tube between the air cleaner and the engine.

A breather heater will keep the tube warm enough to prevent ice from forming. The breather heater fits inside the tube. The heating coil gets its power from the generator by connecting to the back terminal of a selected receptacle. After the breather heater kit is installed, it may remain on the generator and operate year-round.
