Air Shutter Adjustment
The burner aeration is factory set, but may need adjustment due to altitude
or the local gas supply.
Air shutters increase or decrease the amount of air mixed with fuel, af-
fecting combustion and how the flame looks. Low primary air will create a
taller, yellower flame, and higher primary air a lower, bluer flame.
Air shutter adjustment is not just for appearance - not enough primary
air may lead to carboning, sooting, or a flame that reaches the top of the
firebox. Units that are burning propane, installed at higher elevations, or
run on high most of the time may need more primary air.

*At higher elevations, air shutter settings may have to be opened
more to compensate.
• *Carbon will be produced if the air shutter is closed
too much.
• Aeration adjustment should only be performed by an
authorized Regency installer at the time of installation
or service.
• Any damage due to carboning resulting from improperly
setting the aeration controls is NOT covered under
warranty.
