Oil Furnaces
An oil fired warm air furnace uses no. 2 fuel oil burned in a sealed chamber
to heat an exchanger. Then with the help of a blower or fan, forces
air across the exchanger into ductwork to warm the structure.
Its basic components are the burner, heat exchanger, fire box, blower, and
cabinet, sometimes known as the jacket.
Accessories that can be installed inside or outside of the unit include a
fan center (usually a low voltage relay that can turn the blower
on independent of the heat cycle), an air filter, electronic air
cleaner or high performance media filter, humidifier, and air
conditioning evaporator coil. With central air, sometimes a condensate
pump will be used to remove the water discharged in the dehumidification
action of the air conditioning.
A zone control panel and motor actuated dampers will be present on the furnace
or ductwork if the system is zoned.
Routine maintenance includes monthly filter replacement or washing the electronic
air cleaner grids when in constant use, cleaning the humidifier
if so equipped, and an annual tune up of the burner.
An oil burner tune up includes a nozzle and filter replacement, heat exchanger
and smoke pipe cleaning, and a fuel to air mixture adjustment.
Since the mixture adjustment requires the use of special instruments
to meet federal standards, it is best left to a professional to
obtain peak efficiency.
