INSTALL CLOSET BOLTS
Install closet bolts in ange channel
and slide into place parallel to wall.
Place a strip of masking tape vertically
up each side of the toilet bowl to
indicate where the mounting holes are
for the Closet Bolts. Apply Wax Ring
and press rmly to hold in place.
Carefully lift the toilet bowl on top of
the 2x4's while aligning the masking
tape on the oor to the masking tape
on the side of the toilet. Connect the
20" water supply to the toilet.
RECOMMENDATION: 2 people to aid
with this task.
Lay a ashlight on the oor illuminating
towards the closet ange and bolts.
View through the seat mounting holes
(see diag.) to see the toilet mounting
hole and closet ange bolt below. The
toilet mounting hole can be seen at a
slight angle, not straight up or down.
While observing where the bolt is in
reference to the toilet mounting hole,
carefully align the bowl over the closet
bolts until centered.
Carefully lower the front 2x4 on its at
side, then check to see if the ange
bolts are still coming through the toilet
mounting holes. (Realign if necessary)
Lower the rear 2x4 checking that the
ange bolts are still coming through
the toilet mounting holes. Once the
ange bolts are lined up with the toilet
mounting holes, carefully slide out the
front 2x4 followed by the rear 2x4.
Apply weight evenly. Do not move after
placement. Water tight seal my break.
Install all nuts and washers and insure
not to over tighten to avoid damage to
bowl.
