Burner Adjustment Procedure

WARNING

Air shutter adjustment should only be performed by a qualified professional service technician.

CAUTION

The adjustment rod and nearby appliance surfaces are hot. Exercise caution to avoid injury while adjusting flame appearance.

If the burner flame appearance differs greatly from what is shown in Figure 13 (see Burner Flame Appearance), some adjustment from the factory setting 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.).

See Table 5 on Page 8 for Burner Air Shutter Adjustment Guidelines.

Initially, always position the air shutter to the factory setting as shown in Figure 14 (adjust- ment 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 proper flame appearance is achieved.

LOGS, VERMICULITE AND EMBERS

Installation Instructions

WARNING

If logs are not installed according to the directions shown here, flame impingement and improper combustion could occur and result in soot and/or excessive production of carbon monoxide (CO) - a colorless, odorless, toxic gas.

Carefully install the seven-piece log set into the firebox as shown in these instructions. All logs should fit onto corresponding pins and/or log stoppers. This will ensure a proper flame and safe combustion.

Note: Place some vermiculite around burner before installing logs (see Figure 24). The entire bag of vermiculite will NOT be used.
