B. Locate the ash lip from packaging (Step 2). Remove the 2 bolts from
the tapped holes in the ash lip. Align the ash lip below the firebox as
shown in Figure 36 (the tapped holes in ash lip should align with
corresponding slots below firebox). Reinstall the 2 bolts that were
removed from the ash lip (finger tight only. If a tool is used, be careful
not to overtighten).
Air Shutter Adjustment Guidelines:
If the burner flame appearance differs greatly from what is shown
on Page 21 (see Figure 33), some adjustment from standard for the
air shutter gap may be necessary (to compensate for variables in the
installation and fuel such as, BTU value / composition, gas pressure,
specific gravity of gas, altitude, etc.).
The following chart is provided to aid you in achieving the correct air
shutter adjustment for your installation.

Burner Adjustment
Initially, always position the air shutter to the factory setting as shown
in Figure 34 (adjustment rod is located in the lower control area). This
can be done by moving the adjustment rod up or down accordingly.
Allow the burner to operate for at least 15 minutes. Observe the flame
continuously. If it appears weak or sooty as previously described,
adjust the air shutter to a more open position until the desired flame
appearance is achieved.
The adjustment rod and associated adjustable air shutter is patented
technology. Flame adjustments can be made quickly and accurately to
taste without the need of disassembling the appliance and waiting for
30 minutes after each adjustment.
