WARNING
Carbon Monoxide Hazard
To prevent serious injury or death:
●
ALWAYS visually inspect the vent pipe before
inserting the vent pipe into the water heater
collar. The vent pipe inserted into the water
heater exhaust collar must be free from
damage or defects for the vent installation
detector to operate properly. If the vent pipe
is damaged, then replace it with new vent
pipe.
●
The vent installation detector only detects
separation of the vent pipe from the water
heater exhaust collar if fully inserted 2-

(70 mm). The vent installation detector will
not detect the separation of connected vent
pipe if the joints become detached or are
leaking flue gas that may contain carbon
monoxide.
●
It is the installer's responsibility to install the
vent pipe properly, to check for leaks, and to
adequately secure the water heater to the
wall.
