The FireStar™ insert comes with four 3/8”X 3” leveling bolts
(two for use at the rear and two at the front of the insert).
The two at the rear can be used to raise the back of the insert
resting on the fireplace hearth. The two at the front can be
used to adjust the front of the insert on the hearth extension.
To install the bolts a 3/8” nut should be threaded onto the
bolt, followed by a 3/8” flat washer. The bolt should then
be installed from the under side of the insert into the captive
nut in the bottom of the insert. When the bolt is adjusted
to the proper height the nut previously threaded onto the
bolt can be snugged up to the insert bottom.
