Oil-Fired Unit Heaters

Direct oil-fired, suspended unit heaters operate on the same principle as the larger oil-fired heating equipment (furnaces, boilers, water heaters, and so on). An oil burner located on the outside of

the unit supplies heat to the combustion chamber, and a fan blows the heat into the room or space to be heated (see Figure 2-94).

An oil-fired unit heater should be located where it will heat efficiently and where it will receive sufficient air for combustion. Proper venting is also important. The waste products of the com- bustion process must be carried to the outdoors.
