Mechanical installation

Most combustion processes run only slightly negative or positive in pressure,
so that the probe flange is for mechanical mounting only. The probe is not
rated for high pressures. If this is a new installation, a weld plate for welding
to the flue gas duct can be supplied.
WARNING
Electrical shock
Failure to install covers and ground leads could result in serious injury or
death.
Install all protective covers and ground leads after installation.
1.1.1 Probe installation
Complete the following steps to install the probe in the duct.
Prerequisites
Ensure all components are available to install the probe.
Procedure
1. If using the optional ceramic diffusion element, the vee-deflector
must be correctly oriented. Before inserting the Rosemount 6888C
probe, check the direction of gas flow in the duct. Orient the vee-
deflector so the apex points upstream towards the flow.
