Fireye® NXCESO2P42 1012379

It is intended for the oxygen concentration sensing element to be replaced without the need to remove the oxygen probe from the stack. Caution must be exercised as surfaces on and around the flue stack can be extremely hot and as such, the user should wear the necessary and sufficient protective clothing. If it is possible to shut burner/boiler system down, do so and remove power. If it is necessary to keep the burner/boiler system online then in the PPC4000, trim should be disabled and power removed from the O2 probe. To disable O2 trim, refer to the PPC-4001 manual. Under the O2 setup menu, for O2 control select disable. Remove power from the O2 probe by disconnecting the 24 VDC at terminal P2 of the PPC4000 or by disconnecting power at the O2 probe terminal strip.
