4. Setup and Installation
Installation of the Robertshaw 700-515 Gas Valve should only be performed by a qualified technician. Ensure all local codes and regulations are followed.
- Gas Supply Shut-off: Turn off the main gas supply to the appliance.
- Electrical Disconnection: Disconnect all electrical power to the appliance.
- Remove Old Valve: Carefully disconnect and remove the existing gas valve, if applicable.
- Mounting: Mount the new Robertshaw 700-515 valve in the correct orientation as specified by the appliance manufacturer.
- Gas Connections: Apply pipe sealant suitable for gas to the male threads of the gas piping. Connect the gas supply line to the inlet port (National Pipe Tapered) and the appliance gas line to the outlet port (NPT). Tighten connections securely.
- Electrical Connections: Connect the thermostat wires to the 'TH' terminals and the thermopile wires to the 'TP' terminals as per the appliance wiring diagram.
- Leak Test: Turn on the main gas supply. Check all gas connections for leaks using a non-corrosive soap solution. Bubbles indicate a leak. Tighten connections or reapply sealant as necessary.
- Restore Power: Restore electrical power to the appliance.
5. Operating Instructions
Follow these steps to operate the gas valve and light the pilot (if applicable to your appliance).
- Turn Control Knob to OFF: Ensure the control knob is in the 'OFF' position and wait at least five minutes to allow any accumulated gas to dissipate.
- Turn Control Knob to PILOT: Depress the control knob and turn it to the 'PILOT' position.
- Light Pilot: While holding the knob down, use a match or igniter to light the pilot burner. Continue to hold the knob down for approximately 60 seconds after the pilot lights to allow the thermopile to heat up.
- Release Knob: Release the control knob. If the pilot flame extinguishes, repeat steps 2 and 3.
- Turn Control Knob to ON: Once the pilot remains lit, turn the control knob to the 'ON' position. The main burner should now operate under thermostat control.
To shut down the appliance, turn the control knob to the 'OFF' position. For temporary shutdown, turn the thermostat to its lowest setting.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your Robertshaw 700-515 Gas Valve. All maintenance should be performed by a qualified service technician.
- Annual Inspection: Have the gas valve and associated appliance inspected annually by a qualified technician.
- Cleanliness: Ensure the area around the gas valve is kept clean and free from dust, debris, and obstructions.
- Pilot Flame Check: Periodically observe the pilot flame (if applicable). It should be steady and blue, enveloping the thermopile sensor.
- Leak Checks: Re-check gas connections for leaks periodically, especially if the unit has been moved or serviced.
7. Troubleshooting
This section addresses common issues you might encounter. For complex problems, contact a qualified service technician.
| Problem | Possible Cause | Solution |
