Aeration Adjustment
All gas fireplaces mix a certain amount of air with the fuel prior to
combustion. This is known as an "Aeration" setting. This is adjustable
and needs to be set based on various factors such as:
1). Type of fuel
2). Altitude of installation
3). Type of burner
4). Home owners preference to blue or yellow flames.
The unit has an externally adjustable aeration setting, which means it
can be adjusted during operation. The minimum air aeration setting
is factory set but may need adjustment in the field. Fireplaces need
approximately 45 minutes to get up to temperature. Aeration settings
should only be made when the unit is at full operating temperature.
The aeration setting lever can be accessed using the Door Tool that
comes with the unit. The aeration setting lever is located underneath
the firebox, at about the middle of the unit. Pulling the lever forward
increases the aeration setting and pushing rearward decreases the
aeration setting. The ideal setting will result in a flame that is about
2/3 blue and 1/3 yellow. If you have a burner that is sooting or have
soot deposits on your logs or glass, the aeration setting is too small
and should be set larger.
