installation
The burner aeration is factory set but may need adjusting due to either the
local gas supply or altitude.
Air Shutters are required to increase or decrease the amount of air that is
mixed with the fuel before combustion. This will have an affect on how well
the fuel combusts and how the flame appears physically.
Low primary air will leave a taller, yellower flame while higher primary air will
leave a lower, bluer flame.
This setting is largely for appearance, however, not enough primary air may
lead to carboning, sooting or a flame that reaches the top of the firebox.
Situations that may require more primary air are; units that are burning
propane, units installed at higher elevations or units that are run on high
most of the time.

driftwood log set.
AIR SHUTTER ADJUSTMENT
CAUTION:
Carbon will be produced if air shutter is closed too much.
Note: any damage due to carboning resulting from improperly setting
the aeration controls is NOT covered under warranty.
Note: Aeration Adjustment should only be performed by an authorized
Regency Installer at the time of installation or service.
