Configuració i instal·lació
Installation of this ignition kit requires technical expertise and should only be performed by a qualified service technician. Refer to the detailed instructions included with the physical product for specific wiring diagrams and mounting procedures.
- Desconnexió d'alimentació: Ensure all electrical power to the appliance is disconnected at the main service panel before beginning any installation.
- Identificació de components: Identify all components of the kit: the control module (780-845), the gas valve, and the igniter/sensor assembly.
- Mounting the Control Module: Mount the control module in a location protected from heat, moisture, and vibration, ensuring proper ventilation.
- Connexions de cablejat: Connect the control module to the appliance's electrical system, gas valve, and igniter/sensor according to the provided wiring diagram. Pay close attention to the terminal markings (e.g., 24V, GND, T, H, V, M, P, LED).
- Gas Valve Installation: Install the gas valve in the gas supply line, ensuring proper orientation and leak-free connections.
- Igniter/Sensor Placement: Position the igniter/sensor assembly correctly in relation to the pilot burner for optimal spark and flame sensing. Ensure the spark gap is set to 7/64 inches.
- Comprovació del sistema: After installation, perform a thorough system check for gas leaks and proper electrical connections before restoring power.
Instruccions de funcionament
The Robertshaw 712 Series operates automatically once installed and powered.
- Call for Heat: When the thermostat calls for heat, the control module initiates the ignition sequence.
- Ignició pilot: A spark is generated at the igniter, igniting the pilot flame.
- Detecció de flama: The flame sensor detects the presence of the pilot flame.
- Ignició del cremador principal: Upon successful pilot ignition and sensing, the main gas valve opens, allowing the pilot flame to ignite the main burner.
- Monitorització de flama: The system continuously monitors the main burner flame. If the flame is lost, the system will attempt re-ignition or shut down for safety.
- Heat Cycle Completion: When the thermostat is satisfied, the main burner and pilot flame are extinguished.
To reset the thermostat to its lowest setting, refer to the specific instructions for your thermostat model.
Manteniment
Regular maintenance by a qualified service technician is recommended to ensure the safe and efficient operation of your heating appliance and the ignition system.
- Inspecció anual: Have the entire heating system, including the ignition kit, inspected annually by a professional.
- Neteja: Ensure the igniter/sensor and pilot burner area are free from dust, debris, and corrosion.
- Comprovació del cablejat: Comproveu periòdicament totes les connexions del cablejat per comprovar si estan ben ajustades i si hi ha signes de desgast o danys.
- Pilot Flame Observation: Observe the pilot flame during operation to ensure it is strong and stable.
Do not attempt to repair the control module. If a malfunction is suspected, the unit should be replaced by a qualified technician.
