Operation Check and Aeration Adjustment
Turn the
replace up and down using the remote control to con
rm
that the full range of inputs is achieved.
Light the
re and allow to warm up for 10–15 minutes to evaluate
the
ame picture.
The burner is equipped with an adjustable air
shutter to control primary aeration. See
gures below. The shutter is
factory-set at an aeration gap, which will give optimum performance
for the vast majority of installations. In a few unusual installations,
ame picture may be improved by adjusting the aeration. The need
for adjustment should be determined only by operating the appliance
with the ceramic fuel effects and window installed.
Increasing aeration
will cause the
ame to appear more
transparent and blue making the ceramic fuel effects
glow more.
Decreasing aeration
will cause the
ames to appear
more yellow or orange making the fuel effects glow less.
Too little aeration may result in black carbon
forming and dropping into the
fi
rebox.
