Fan-Type, Power-Vented Model
with Intermittent Spark Pilot,
Single-Stage Heating,
Natural or Propane
W.R 1C30-339 THERMOSTAT W-S23-6 SUBBASE
SET ANTICIPATOR AT 0.8 AMPS
OPERATING SEQUENCE
1. SET THERMOSTAT AT LOWEST SETTING.
2. TURN ON MAIN AND PLOT MANUAL GAS VALVES.
3. TURN ON POWER TO UNIT.
4. SET THERMOSTAT AT DESIRED SETTING.
5. THERMOSTAT CALLS FOR HEAT ENERGIZING THE VENTER MOTOR.
6. VENTER PRESSURE SWITCH CLOSES FIRING UNIT AT FULL RATE AFTER PILOT
PROVING SEQUENCE.
7. FAN CONTROL SENSES HEAT EXCHANGER TEMPERATURE, ENERGIZING THE
FAN MOTOR.
8. IF THE FLAME IS EXTINGUISHED DURING MAIN BURNER OPERATION THE SAFETY SWITCH
CLOSES THE MAIN VALVE AND RECYCLES THE SPARK GAP. ON UNITS EQUIPPED
WITH THE G77ONGC-4 LOCKOUT CONTROL, IF PILOT IS NOT ESTABLISHED WITHIN 120
SECONDS (APPROX.) UNIT LOCKS OUT AND THE UNIT MUST BE RESET BY
INTERRUPTING POWER TO CONTROL CIRCUIT (SEE LIGHTING INSTRUCTIONS).
NOTES
1. THE FOLLOWING CONTROLS ARE FIELD INSTALLED OPTIONS:
THERMOSTAT
2. THE FOLLOWING CONTROLS ARE FACTORY INSTALLED OPTIONS:
S/W SWITCH
3. DOTTED WIRING INSTALLED BY OTHERS.
4. CAUTION: IF ANY OF THE ORIGINAL WIRING AS SUPPLIED WITH THE APPLIANCE MUST BE
REPLACED, IT MUST BE REPLACED WITH WIRING MATERIAL HAVING A TEMPERATURE
RATING OF AT LEAST 105 DEGREES C., EXCEPT FOR SENSOR LEAD AND
LIMIT WIRING WHICH MUST BE 150 DEGREES C.
5. USE #18 GA WIRE FOR ALL WIRING EXCEPT FAN MOTOR CIRCUIT.
6. LINE AND FAN MOTOR BRANCH WIRE SIZES SHOULD BE OF A SIZE TO PREVENT VOLTAGE
DROPS BEYOND 5% OF SUPPLY LINE VOLTAGE.
7. ON 230V. UNITS THE CONTROL TRANSFORMER HAS A DUAL VOLTAGE PRIMARY.
FOR 230V. UNITS USE BLACK AND YELLOW LEADS (CAP RED).
FOR 208V. UNITS USE BLACK AND RED LEADS (CAP YELLOW).
ON 115V. UNITS THE CONTROL TRANSFORMER IS A SINGLE VOLTAGE PRIMARY.
FOR 115V. UNITS USE BLACK AND YELLOW LEADS.
8. SEE INSTALLATION INSTRUCTIONS FOR GREATER DETAIL.
