Installation
Checking Operation
Turn the fi replace fl ame up and down using the
remote control to confi rm that the full range of
inputs is achieved—see the remote control operation
instructions in "Appendix B—Remote Control
Operation" on page 64.
Adjusting Aeration
Light the fi re and allow the unit to warm up for 10–15
minutes to evaluate the fl ame picture. The burner is
equipped with an adjustable shutter to control primary
aeration. The shutter is factory-set to an aeration gap
which will give optimum performance for the vast
majority of installations.
Depending of the fuel bed used, altitude and other
considerations, the fl ame picture may be improved by
adjusting the aeration. The need for adjustment should
be determined only by operating the appliance with the
fuel bed, panels and window installed and evaluating
the fl ame picture after a 15-minute warm-up.
Increasing aeration will cause the fl ames to appear
more transparent and blue showing more ceramic
eff ects glow.
Decreasing aeration will cause the fl ames to appear
more yellow or orange showing less ceramic eff ects
glow.
Too little aeration may result in black carbon forming
on logs or roof panel and dropping into the fi rebox.
