Additional maintenance to the heater will also be required.

Kerosene breaks down over time. Never use kerosene that has been stored from one season to the next. Never store leftover kerosene over the summer. Using old fuel can damage your heater.

If the flame goes out, will fuel continue to pump?
The heater uses a photocell to “see” the flame in the combustion chamber. Should the flame extinguish, the sensor will stop electrical current, and the heater will shut off.
Turned power off but the fan still runs?
This heater must cycle through a "Cool Down Phase" in which the fan continues to run for apromaxily 3 minutes to circulate air through the combustion chamber to cool it before shutting off completely.
What happens if the heater loses electrical power, or is accidentally unplugged?
Heater may re start when reapplying power. If the heater does not re start, but the fan is running, when it was plugged back in, it will have to complete the "Cool Down Cycle" before restarting.
