The compact L-30 is a flexible little direct vent heater.
Use it to supplement heat in a large house or as the primary heat source in a small dwelling – it's approved for use in mobile and manufactured homes. It's not fusssy about fuel and will run happily on K1 kerosene, No. 1 fuel oil, or ultra-low sulfur diesel. Vent it directly through a 3” hole in your wall with its self-adjusting flexible pipe.
Other features include a programmable digital thermostat that retains settings if power is interrupted and an automatic safety shutoff.
The heater requires electricity to run its fan and thermostat, and an outdoor storage tank for fuel.
