Log Set
Log Installation Instructions
If logs are not installed according to the log installation instructions,
flame impingement and improper combustion could occur and result
in soot and/or excessive production of carbon monoxide (CO), a color-
less, odorless, toxic gas.
The size and position of the log set is critical to achieve a safe, reli-
able and attractive flame pattern. Any attempt to use a different log
set in the fireplace will void the warranty and will result in incomplete
combustion, sooting and poor flame quality.
1. Remove the six logs from the box and foam packaging. Lay them out
for easy identification during installation.
2. Place rear log on insert tabs (these tabs will penetrate the center of
the log) at the rear of the burner.
3. Place a light (fluffed) layer of embers (rockwool) directly on top of
the port holes in the burner. CAUTION: A 1/4” (6.4mm) air space
between the rockwool and lower base of the rear log needs to be
maintained for combustion air and proper flame aesthetics.
4. Place Log #2 on tab. An air shield is provided for natural gas use only.
For LP conversions, remove the air shield.
5. Place Logs #3, #4 and #5 on tab inserts.
Important!!! Maintain a 1/4” (6.4mm) air
space along the entire length of log.

Brick Panel and Log Set Installation
Brick Panel
The brick panels are extremely fragile so handle them with care.
1. Remove brick panels from box and wrapping.
2. The long rectangular panel goes in the rear of the firebox - the thin layer
of bricks should be down. The panel rests on three metal tabs protruding
from the rear of the firebox about 3” above the firebox floor.
3. On the side panels, the rounded edge goes to the front. Install the side
panels by sliding them along the side of the firebox into retainers at
the top and bottom.

not directly over the burner ports.
