Adjust the Carriage Height (cont.)
Loosen the nuts securing the legs to the carriage.
NOTE: As the carriage is lowered, make sure the elbow aligns with
the toilet drain pipe.
NOTE: If applicable, confirm the gasket on the elbow stays
correctly positioned as it enters the toilet drain pipe.
Adjust the carriage until the desired height is reached. Securely
tighten the nuts using a wrench to secure the legs in place.
NOTE: If a cast iron elbow is required, make the connections
following all applicable codes.
