The MPI Monitor heater M441 runs on clear kerosene, with a flue leading to the chimney or the outdoors for safe indoor heating. To keep your heater running safely and efficiently, it's important to keep it clean, both on the outside and the inside.
Your MPI Monitor heater must be free of surrounding clutter. Don't use the heater as a table -- it's not the place to set pictures, figurines or plants. Likewise, never drape fabric over the heater or use it as a clothing dryer. Keep papers, books and trash away from the heater, and never keep any kind of flammable material, such as cleaning solvents, alcohol and aerosols, in the vicinity of the heater.
Cleaning the Exterior
The exterior cabinet of your MPI Monitor heater should be dusted frequently to prevent clogged vents. Simply run a static duster over the cabinet at least once a week while you do you regular light cleaning in the room. If the exterior looks dingy, wipe it down with a damp microfiber cloth. Do not use abrasive or flammable cleaners. If you use an all-purpose cleaner on the cabinet, spray it on the cloth, not the heater.
Cleaning the Interior
Periodic cleaning of the inside of your MPI Monitor heater helps to keep the unit running efficiently. Before cleaning the inside, turn off the heater and allow it to cool completely. Remove the screws around the edge of the heater's louvers. Vacuum the interior using a brush hose attachment to remove dust, cobwebs and dirt. Remove any small objects that may have fallen inside through the vents. Wipe away any excess dust and dirt with a microfiber cloth.
Fuel Strainer Cleaning
Once a year, the MPI Monitor heater's fuel strainer must be cleaned. This job requires you to turn off the kerosene tank's shutoff valve. Place a cardboard-lined container under the fuel strainer cover, located on the lower right side of the unit. Remove the screws from the fuel strainer cover and allow the excess fuel to drip into the container. Remove the fuel strainer and wash it with fresh, clear kerosene -- do not clean it with water. Once the strainer is clean, place it back to its position and replace the cover. Discard the fuel-soaked cardboard from the container. Sprinkle any kerosene drips with baking soda; once the fuel is absorbed, wipe it away with a paper towel.
