With its leads pointing in the direction shown in the figure, and install the sensor onto the straight pipe
part of gas side pipe. Match the sensor protective tube colors with the pipe marking colors and install
the sensors. TGa is yellow,TGb is red, and TGc is green.
During the installation work (and on its completion), take care not to damage the coverings
of the sensor leads on the edges of the metal plates or other parts. It is dangerous for
these coverings to be damaged since damage may cause electric shocks and/or a fire.
After replacing the parts, check whether the positions where the sensors were installed are the proper
positions as instructed. The product will not be controlled properly and trouble will result if the sensors
have not been installed in their proper positions.
