Oil Fired Heaters

Component Description and Operation

Toro Spark Plug

The spark plug must be positioned all the way in against the housing; line up the red line of the spark plug with the casting

line on the burner. Gap the spark plug to .062"(FIG. 9). If plug is fouled, clean or replace.

Test spark plug by removing top cover, remove air gauge plug, loosen setscrew and remove spark plug from the burner.

Leave the wire attached to the spark plug and lay the plug across the sheet metal of the heater. Loosen setscrew and remove

fan blade, plug in the heater and the spark should jump continuously across the electrodes.

Fuel System (Fuel Filters)

There are several types of fuel filters used on different model heaters. The filters are always located in line with the fuel pickup

tube (FIG. 10). The purpose of the filter is to eliminate the possibility of dirt, dust, etc. from entering the nozzle and restricting

the flow. The filters should be inspected and cleaned whenever a heater is brought in for service. It is also important that the

bottom of the tank be inspected for sedimentation or dirt build-up. The filters design is such that a possible restriction in the

filter screen can be present during operation and be dislodged back into the tank when the heater is shut off.
