Howard St., Chicago, IL 60648 FORM 5S2514 MODELS 3E358A & 3E359A 01582 Troubleshooting Chart SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION Odor and smoke from heater 1. Air leak in suction system 2. Low pump pressure 3. Dirty filter 4. Dirty burner nozzle 5. Low voltage causing motor to operate below rated speed 6. Water deposits suspended in fuel 7. Low motor RPM 1. Check filter for leakage. Tighten all fuel line connections. 2. Adjust pump pressure. 3. Clean the filter element and filter bowl. 4. Clean the burner and replace nozzle. 5. Voltage at heater should be not less than 90% of rated voltage. (108 volts for 120-volt heaters.) 6. Wait for water to settle out after filling tank; then drain tank and refill with fuel containing no water. 7. Check voltage, if OK, check motor RPM. Motor must run at least 1700 RPM on proper voltage. If not, replace motor. Failure to start (Motor does not start when thermostat is set to : call for operation) 1. Proper power not reaching heater 2. Loose electrical connections 3. Control not activated 4. Motor overload protector tripped 5. Thermostat defective 6. Safety control defective 7. Damaged power relay 1. Check that heater is connected to a live power line with good fuses, and that the voltage at the heater is correct. 2. Check; tighten if necessary. 3. Press and release reset button on control. 4. Check for cause of motor overload. Correct cause or replace motor. 5. Replace thermostat. 6. Replace safety control. 7. Replace power relay. Heater will not ignite (Motor runs when thermostat is set to call for operation.) 1. Fuel tank empty 2. Spark plug dirty or not properly gapped 3. Solenoid valve not opening 4. Improperly wired after servicing 5. Pump not providing fuel, or providing fuel at too-low pressure 6. Water in fuel 1. Fill fuel tank. 2. Reset spark plug after cleaning, according to dimensions in Figure 4. 3. If electrical connections to solenoid valve are good, replace solenoid valve. 4. Check wiring according to Wiring Diagram, Figure 2. 5. Check pump output pressure; adjust if necessary; replace pump if adjustment cannot be made or will not hold. Filter element needs cleaning. 6. Drain tank, rinse with clean fuel; clean filter element and filter housing. Refill with clean fuel. Nuisance trip-outs 1. Open or damaged photocell 2. Defective safety control 3. Defective fan switch 1. Replace photocell. 2. Replace safety control. 3. Replace fan switch. -6- FORM 5S2514 MODELS 3E3S8A & 3E359A 01582 Operation (Continued) QPERATING SEQUENCE jie following is a description of the normal automatic ^operating sequence of the heater (See the Wiring Diagram, Figure 2). 1. The heater is turned on by the theromstat automatically in response to a temperature setting of the dial, provided the setting is higher than the surrounding air temperature. 2. When operation is called for, the transformer and the motor, fan and fuel pump start operating immediately. 3. After fan reaches running speed, the solenoid valve will open. This allows fuel to flow to the nozzle. The heater will then ignite. 4. After about 2 minutes, the purge circuit is energized. 5. When the thermostat setting equals the surrounding air temperature or is turned to the COOLEST position, the solenoid valve shuts off the flow of fuel to the nozzle, and the fire goes out immediately. The fan continues to run, purging the heater. 6. When the combustion chamber cools, the thermal switch changes back to its starting position, shutting off the motor. 7. If, for some reason, the fire goes out before the thermostat is satisfied, or if the heater fails to ignite when operation is called for, the safety control will shut off the heater with in 10-40 seconds. If this should occur, unplug the heater, and determine the cause of | the shutdown. Correct the cause then press the reset v_J button on the safety control and restart the heater. Maintenance Maintenance consists of the operations the owner or user of the heater can perform to keep the heater operating properly. If routine maintenance fails to return a heater to top-operating condition, refer to the Trouble Shooting Chart. Keep the heater clean to reduce the need for extensive maintenance or repair. FUEL SYSTEM MAINTENANCE 1. Use the cleanest fuel available. Dirt and water in the fuel will clog the filter, and may cause the heater to burn with an odor. If there is excessive water in the fuel, the flame may go out. Every 250 hours (or mo...
