Burner Adjustments

The following paragraphs address burner adjustment 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 surfaces adjacent to the face opening. 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 excessive 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.

Burner adjustment

Caution : The Shutter And Nearby Appliance Surfaces Are Hot. Exercise Caution To Avoid Injury While Adjusting 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 6.

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.

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.

Warning : The Size And Position Of The Log Set Was Engineered To Give Your Appliance A Safe, Reliable 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.

Caution : Never Operate The Fireplace Without The Lava Rocks In The Burner Pan. Prolonged Use Without The Rock In Place Will Overheat The Pan And Cause The Fireplace To Shutoff Automatically.

After verifying that the fireplace operates properly, replace the cover and set the bottom refractory components in place.
Use two (2) bags of lava rock to fill the bottom of the burner tray to completely cover the burner tube. Level the rock evenly.
Place the rear log approximately centered as shown in Figure 7.

Place the base log approximately as shown in Figure 8.

The remaining logs can be placed across the rear and base log approximately as shown in Figure 9. The exact position of these logs is not critical. Due to the nature of an outdoor environment, the flame will never be strictly controlled. You may need to reposition the logs to get the effect you find most desirable.

Warning : Lava Rock Within The Burner Can “Pop” For The First Few Fires. Wind Borne Debris May Also Enter The Fireplace Inexpediently.
In High Wind Conditions, Operate The Appliance With The Screens Or Doors Closed.

Electronic Appliance Checkout

To light the burner, refer to the lighting instructions on . Ensure the ignitor lights the pilot. The pilot flame should engulf the flame sensor as shown in Figure 10.
