Step 10. BURNER ADJUSTMENTS

Step 10. BURNER ADJUSTMENTS

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 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 vent termination. Sooting is caused by incomplete combustion in the

Allow the burner to operate for at least 15 min- utes. Observe the flame continuously. If it ap- pears weak or sooty as previously described, adjust the air shutter by pushing or pulling on the adjustment rod until the flame appearance is as desired.

The adjustment rod and associated adjustable air shutter is patented technology. Flame adjust- ments can be made quickly and accurately to taste without the need of disassembling the appliance and waiting for 30 minutes after each adjustment.

Note: If the flame still appears anemic with the air shutter closed all the way against the stop (usually a result of lengthy vertical runs), turn the appliance off, turn the gas supply off, wait for the parts to cool, remove the glass door and

Step 11. HOOD INSTALLATION

All of these appliances must have hoods installed prior to operating.

On all clean face units, slide the hood into the slots on the lower edge of the radiant panel (Figure 55 ).

On louvered face units, slide the hood into the slots on the lower edge of the cabinet top (Figure 56 ).

flames and 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.

No smoke or soot should be present. Reposition the logs if flames impinge on any of them.

If the logs are properly positioned and sooting conditions exist, the air shutter opening on the main burner tube should be adjusted. Normally, the more offsets in the vent system, the greater the need for the air shutter to be opened further.

logs to access the air shutter. The shutter is prevented from actually closing all the way by an adjustment set screw (see Figure 54). Re- move this screw using a ¹⁄₄ inch nut driver. Reinstall the logs and glass door, turn the gas back on and then restart the appliance. After 30 minutes, reobserve the flame. Adjust the air shutter as previously described.

When satisfied that the appliance operates properly, proceed to finish the installation. Leave the control knob in the ON position and the remote switch OFF. Close the lower control compartment door.
