The gas inlet tube assembly has been packaged separately to avoid breakage

To install the gas inlet assembly:
1. Carefully remove the assembly from the package and inspect for any damage.
2. Remove the two mounting screws from the rear housing panel of the furnace.
3. Insert the ceramic tube end through the access hole in the rear of the furnace
and guide the tube into the back of the chamber.
4. Align the mounting holes in the rear housing panel with the holes in the gas
inlet tube assembly and secure the assembly with the mounting screws.
