OPERATING SEQUENCE
1. SET THERMOSTAT AT LOWEST SETTING, (FAN SWITCH
2. TURN ON MANUAL GAS VALVE.
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.
7. BURNER FLAME IS SENSED, AND IN 30 SECONDS THE FAN
MOTOR IS ENERGIZED.
8. IF THE FLAME IS EXTINGUISHED DURING MAIN BURNER OPERATION,
THE INTEGRATED CONTROL SYSTEM CLOSES THE MAIN VALVE AND
MUST BE RESET BY INTERRUPTING POWER TO THE CONTROL CIRCUIT
(SEE LIGHTING INSTRUCTIONS).
NOTES
1. THE FOLLOWING CONTROLS ARE FIELD INSTALLED OPTIONS: THERMOSTAT
2. DOTTED WIRING INSTALLED BY OTHERS.
3. 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° C. EXCEPT FOR SENSOR
LEAD WIRE, FLUE LIMIT CONTROL AND LIMIT WIRING WHICH MUST BE 150° C.
6. USE #18 GA. WIRE FOR CONTROL WIRING ON THE UNIT.
4. LINE AND FAN MOTOR BRANCH WIRE SIZES SHOULD BE OF A SIZE TO PREVENT
VOLTAGE DROPS BEYOND 5% OF SUPPLY LINE VOLTAGE.
7. CAPACITOR IS REMOTE MOUNTED.
8. SET THERMOSTAT ANTICIPATOR AT 0.6 AMPS.
9. SET FAN SWITCH AT "ON" POSITION FOR CONTINUOUS FAN OPERATION, OPTION CL2 ONLY.
AT "AUTO" POSITION, OPTION CL2 ONLY).
5. USE #14 GA. WIRE FOR LINE WIRING ON THE UNIT.
