4.11 LIGHTING CHECKLIST

Be sure to check these items before final operation of the Fireplace insert.
☐ All items on "Installation Checklist" must be completed.
☐ Carefully follow all lighting and log installation instructions.
☐ Check for Gas leaks and gas pressures prior to installing facing materials.
☐
Air shutter opening 0" to ⅛" for natural gas or ¼" to fully open for LP gas is checked.
☐
All lighting and log installation instructions were followed.
☐
Burners light immediately and flame runs promptly around rear burner and lights entire burner.
Note: Do not proceed with operation unless burner cycles "on/off" without delays.
☐
Flame is "stable" and does not "lift" off burner. If flame lifts off burner, turn unit off and check that all vent pipes are
"twist locked" and leak proof. Do not proceed with operation if flame is "lifting off" burner after first 5 minutes.
☐ DO NOT proceed with operation unless burner cycles "on/off" without delays and the flame is "stable" and not "lifting" off
burner after 5 minutes of initial ignition.
Caution: If pilot goes out, be sure to wait a minimum of five minutes before relighting.
4.12 AIR SHUTTER CONTROL AND FLAME APPEARANCE
During initial installation, the air shutter opening should be checked to
be certain that the shutter is set correctly at 1/8" open for natural gas
and 1/2" minimum open for L.P. gas. NOTE: For altitudes above 5,000',
some variations may be required.
Be sure burner and logs are properly installed. After log set has been
properly installed, adjustments to the air shutter shall be made for final
flame appearance. These small shutter adjustments can be made by the
following procedure:
NOTE: All adjustments to the air shutter setting must be
made by a qualified installer, service agency, or the gas
supplier. Very small changes in shutter settings make major
changes in flame appearance.
The rear burner air shutter adjustment knob is located on the left side of
the gas valve. Push the knob to close the air shutter or pull on the knob
to open the air shutter.
The front burner air shutter is located at the inlet end of the front
burner. This shutter is of the rotary design and is not accessible from outside. If flame is too blue, close air shutter in small 1/8"
increments until flame turns desired realistic yellow. Use glass latch tool to hook end and slide control.
1. If flame is causing soot on viewing glass, open air shutter fully until sooting stops. Continue burning unit with air shutter fully
open for four to six hours until all internal deposited soot has burned off.
2. Once deposited soot has disappeared, close air shutter in increments of 1/8".
LPG Air shutter settings hint: A properly adjusted air shutter setting will yield burner flames that have an
approximate 2" high blue color base. If yellow colored flames are starting at burner level, air shutter is
closed too far and will create soot. If you observe that the flame is yellow starting very close to or at the
burner surface level, open air shutter. Also, if a log or part of a log is suspended and hanging inside a yellow
portion of the flame, soot can form easily on the part of the log that is inside the yellow flame area.
IMPORTANT: Try each new shutter setting approx. ½ hr. before mak ing additional changes. NOTE: Changes
in front burner flame can be made by re -arranging the coals and front burner air shutter opening.
