(see Figure 2).
CAUTION: Do not pick up log
base assembly by burners. This

vice person must connect and
disconnect fireplace to gas sup-
ply. Follow all local codes.

Standard brick panel has larger bricks at the
top while the Herringbone panel has smaller
bricks at the top. Rest the bottom edge of
firebrick panel on liner flange. Stand firebrick
panel straight up against the back of fireplace
(see Figure 3). The side brick panels will hold
the rear panel in place.
CAUTION: Always handle
firebrick panels with two hands.
Do not force firebrick panels into
place. Excessive force will break
firebrick panels.
Note: If your fireplace has a thermodisc plate,
make sure you position the hole in rear fire-
brick panel over the thermodisc plate on rear
wall of fireplace (see Figure 3). If you cover
the thermodisc plate with the firebrick panel,
the fan will not run properly.
