5.2 Normal Lighting and Shut-down Procedures

Normal Lighting Procedures

1. Make sure the system is filled with water and water is circulating in the system. Turn on
electrical supply and open the gas supply valves to the boiler.
2. Turn the on/off switch to the "On" position. If an error is indicated, refer to the NURO Advanced
User's Guide to troubleshoot the problem and take necessary corrective action before
proceeding.
3. Set the desired high temperature limit and operating temperature. The NURO
now begin the automatic firing sequence.

Normal Shut Down Procedures

1. Allow the boiler to turn off on its own once
the temperature satisfies, or remove the call
for heat to the boiler.
2. Once the boiler completes a successful
"Post-Purge" and "Post-Pump", it will return
to "Standby".
3. Once in standby, turn the on/off switch to the
"Off" position.
4. Close all manual gas valves to right.
5. Turn off the electrical disconnect to the
boiler.

5.3 Emergency Shut-Off

In case of emergency, immediately shut off the
gas supply at the valve on the rear surface of the
boiler. See the image to the right for the locations
of the Natural Gas valve (lower) or Propane Gas
valve (upper).
