Firebrick Installation
1a. Firebrick installation in units with an ash dump
1. When installing firebricks onto the floor of a unit with an ash dump, 2 small bricks ("A & B" in Fig ) will
used on either end of the ash dump in addition to the regular sized "D" bricks used in the rest of the
installation. There is one exception. Brick "C" is a shorter brick than "D" bricks are. "C" brick fits up
against a vertical post on the rear wall of the firebox and is used in units with or without an ash dump.
2. Once the firebricks for the floor have been laid down, the firebricks for the side walls are next. The sides
use "D" bricks. The bricks will stand on top of the floor bricks and will stand on their ends. They will be
held in place by two tabs per wall. Install the end bricks first followed by the two center bricks.
