Fuel burning portable heaters are intended to be used in a well ventilated area. Please refer to your operator's manual for the fresh air requirements.

The most important factor when sizing a space heater is the amount of space you have to heat. A general rule of thumb is that you can heat approximately 25 square feet for every 1000 BTUs a heater puts out.

All of the approved fuels for Mi‑T‑M portable heaters have great energy value and one doesn't stand out over another. Your application and the fuel that you have available are going to determine which fuel to use.

The approved fuels are:

• No. 1 and No. 2 fuel oil
• No. 1 and No. 2 diesel fuel
• JP8/Jet A fuel

Mi‑T‑M portable heaters that have a blower motor or a fuel pump will require electricity to power those units. As an example, all of the Kerosene forced air, LP & Natural Gas forced air and the radiant portable heaters require electricity. The convection, outdoor patio heater and the tank top heaters do not require electricity.
