Burner Aeration - Valor PORTRAIT 530IN Installation Manual

Installation
Check Operation
Turn the fireplace flame up and down using the remote
control to confirm that the full range of inputs is
achieved—see Appendix B – Remote Control Operation
pages 43–46 for details.
Adjust Aeration (if needed)
Light the fire and allow the unit to warm up for 10–15
minutes to evaluate the flame picture. Burners are
equipped with an ajustable shutter to control primary
aeration. See figures below. The shutter is factory-set to
an aeration gap which will give optimum performance
for the vast majority of installations.

In some installations, depending of the fuel bed used,
the altitude and other considerations, the flame picture
may be improved by adjusting the aeration. The need
for adjustment should be determined ony by operating
the appliance with the fuel bed and window installed
and evaluating the flame picture after a 15-minute
warm-up.
Increasing aeration (open) will cause the flames to
appear more transparent and blue showing more
ceramic effects glow.
Decreasing aeration (close) will cause flames to appear
more yellow or orange showing less ceramic effects
glow.
Too little aeration may result in black carbon forming and
dropping into the firebox.
