WARNING
The rubber elbow is not designed to support
a load. When the rubber elbow is mounted
externally to the furnace cabinet, extreme
care must be taken to adequately support field-
supplied vent/flue piping, as damage can result
in leaks causing bodily injury or death due
to exposure to flue gases, including carbon
monoxide.
