Position the individual logs as shown below. Logs should be
placed in the order shown. Position the rear log on the brackets
at the rear of the firebox with the log's notches directly over the
brackets. Position the right log (log no. 3) by inserting the pin
from the rear log into the hole on its upper end. Place the left log
and then the smaller left and right top logs. All logs that have
notches to fit over the grate tines should be positioned with these
notches directly against the grate. All top logs that rest on lower
logs, do so over flattened mounting faces in the bottom logs.
Proper log and twig placement is critical to encourage outstanding
flame appearance and prevent sooting.
