Burner Adjustments

The following paragraphs address burner ad- justment concerns and procedures.

Flame Appearance and Sooting

Proper flame appearance is a matter of taste. Generally most people prefer the warm glow of a yellow to orange flame. Appliances operated with air shutter openings that are too large will exhibit flames that are blue and transparent. These weak, blue and transparent flames are termed anemic. If the air shutter opening is too small excessive sooting may develop.

Sooting is indicated by black puffs developing at the tips of very long orange flames. Sooting results in black deposits forming on the logs, appliance inside surfaces and on exterior sur- faces adjacent to the face opening.

Burner Adjustment

CAUTION: THE SHUTTER AND NEARBY AP- PLIANCE SURFACES ARE HOT. EXERCISE CAUTION TO AVOID INJURY WHILE ADJUST- ING FLAME APPEARANCE.

To adjust the flame, turn the shutter (located in the left side of the burner pan) up or down to increase or reduce the air shutter opening, respectively. Position the air shutter to the factory setting, as shown in Figure 4.

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 by rotating the shuter until the flame appearance is as desired.

When satisfied that the appliance operates properly, proceed to finish the installation. Leave the control knob in “ON” position and turn the remote switch “OFF.” Reinstall the access and refractory cover.

Sooting is caused by incomplete combustion in the flames and a lack of combustion air entering the air shutter opening. To achieve a warm yellow to orange flame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes.

These appliances should not smoke. Small amounts of soot will accumulate over time and should be expected. This soot adds to the realism of the firebox interior. The logs can be cleaned, when cool, with a soft brush and small amounts of water.

If the logs are properly positioned and exces- sive sooting conditions exist, the air shutter opening on the main burner tube should be adjusted. Keep in mind that this is an outdoor

appliance. Wind and air currents cannot be strictly controlled.

If the flame acts too erratically, we recommend that the screens be closed.

WARNING: AIR SHUTTER ADJUSTMENT SHOULD ONLY BE PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE TECHNICIAN.

Log Placement

WARNING: LOGS GET VERY HOT AND WILL REMAIN HOT UP TO ONE HOUR AFTER GAS SUPPLY IS TURNED OFF. HANDLE ONLY WHEN LOGS ARE COOL. TURN OFF ALL ELECTRICITY TO THE APPLIANCE BEFORE YOU INSTALL GRATE AND LOGS.

WARNING: THIS APPLIANCE IS NOT MEANT TO BURN WOOD. ANY ATTEMPT TO DO SO COULD CAUSE IRREPARABLE DAMAGE TO YOUR APPLIANCE AND PROVE HAZARDOUS TO YOUR SAFETY.
