The most common heaters you will see in the field are the Portable Kerosene Heaters (or Kerosene Forced Air, KFA). To best help you tackle issues with these heaters, new or used; here are some initial questions our Tech Team will ask you.

1)What is your air pressure?

There is a small carbon vain pump on the back of the fan motor that creates air (typically under 10 PSI) that pumps through the burner head creating a venture to lift the fuel and spray (atomize). So if there’s poor or no air pressure, then there’s poor or no fuel atomization.

2) What is the condition of the fuel?

Good and proper fuel is vital. Old or poor fuel can clog up filters, nozzles and not light correctly.

3) Is there a good spark?

At start up, our KFA Heaters will have spark for 20 seconds. The spark is only for initial lighting; the flame stays lit based on proper air and fuel balance.

4) Is the heater lighting?

If the heater is lighting and how the heater is shutting down are very important indicators. For example, the most common heater problems is when the heater will start, light, run for a few seconds or minutes and then shut down and smoke. Any smoking is a sign of incorrect fuel/air mixture and in most cases is caused by poor fuel atomization at the nozzle. After double checking the air pressure, we would recommend new fuel, a new fuel filter, and cleaning or replacing the fuel nozzle.
