Operation Check
Turn the replace ame up and down using the
remote control to conrm that the full range of inputs
is achieved—see the remote control operation
instructions on pages 36–38.
Aeration Settings (NG units only)
(LPG units do not have any primary air adjustment.)
Light the re and allow the unit to warm up for 10–15
minutes to evaluate the ame picture. Natural gas
burners are equipped with an adjustable shutter to
control primary aeration. See the gures below. The
shutter is factory-set to an aeration gap which will
give optimum performance for the vast majority of
installations.
In a few unusual installations, the ame picture may
be improved by adjusting the aeration. The need for
adjustment should be determined only by operating the
appliance with the ceramic logs and window installed.
Increasing aeration will cause the ames to appear
more transparent and blue showing more ceramic log
glow.
Decreasing aeration will cause the ames to appear
more yellow or orange showing less ceramic log glow.
Too little aeration may result in black carbon
forming and dropping into the rebox.
