Miller is a company that manufactures furnaces for mobile home use. Highly-efficient Miller oil-fired furnaces are convertible between natural gas, propane and oil, and they come with a Beckett oil burner. Like all furnaces, the Miller oil furnace collects dust, debris and dirt over the year. This build-up can clog the furnace and cause it to work less effectively. Clean the furnace in the spring and fall to keep it working well.
Turn off the Miller oil furnace and wait for it to cool. Open the maintenance hatch.
Remove the old oil filter and replace it with a new one. The oil filter is located in the Beckett oil burner near the oil uptake pipe.
Vacuum the Beckett oil burner to remove any dust build up. Wipe the burner with a cloth to remove excess oil.
Vacuum the draft regulator, the plate inside the flue, to remove any dust. Wipe the draft regulator with a cloth.
Vacuum around the Miller oil furnace to keep dust from getting inside the system. Dust off the thermostats throughout your mobile home with the paintbrush.
