INSTALLATION
AERATION
ADJUSTMENT
The aeration adjustment gears are located on
the valve mounting plate and are accessed
from underneath through the bottom louver
opening.
To access the air shutter loosen the lock nut and
then use the allen key to turn the turning gear
which will adjust the air shutter. Open the air
shutter for a blue fl ame or close it for a yellower
fl ame. Tighten the lock nut when adjustment is
complete. The burner aeration is factory set but
may need adjusting due to either the local gas
supply or altitude.
CAUTION: Carbon will be produced if air
shutter is closed too much. (Should be
3/16"(4mm) open for natural gas and 1/2"
(13mm) for propane.)
Note: Aeration Adjustment should only be
performed by an authorized Regency

Installer at the time of installation or
service.
