I-Series Indoor Gas Fireplace
Operation
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 34FID-L 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 a fair amount of time to get up to temperature,
approximately 45 minutes. 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, about half way be into the unit. The lever
pulled forwards increases the aeration setting and push rearward
decreases the aeration setting. The ideal setting will result in a
flame that is about 1/3 blue and 1/3 yellow. If you have a burner
that is sooting or has soot deposits on your logs or glass, the
aeration setting is too small and needs to be set larger.
