Whenyou have arranged all the components into place7)
andyou are working on the top rear rebox, check that
yourwork is level. If you need to, you can make some
adjustments in the top surface of the box assembly
simplyby using shims. Once you are satised with the
degreeof levelness, you can address any gap that may
have occurred with an appropriate amount of mortar.
Althoughyou are cautioned to use mortar sparingly
because it does have such holding power,you should
lookover the rebox assembly at the end and ll any
gaps with mortar especially at joint connections.
