Optional Cast Iron Fret Installation
Operation Check and Aeration Adjustment
Turn the
fi
replace up and down using the remote control to con
fi
rm
that the full range of inputs is achieved.
Light the
fi
re and allow to warm up for 10–15 minutes to evaluate
the
fl
ame picture.
The burner is equipped with an adjustable air
shutter to control primary aeration. See
fi
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,
fl
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
fl
ame to appear more
transparent and blue making the ceramic fuel effects
glow more.
Decreasing aeration
will cause the
fl
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.

Fret Retainer Brackets Installation
Screw 2 thumbscrews into sides of each support
leg if not done previously when support legs were
installed. Fit the slotted holes in the fret retainers over
the thumbscrews, push fret retainers downwards and
tighten screws.
Cast Iron Fret Installation
Adjust screw heads on back of fret to the thickness of
the retainer bracket and drop the fret into place while
guiding the screw heads into the slots in the bracket.
Clip the ash pan cover onto the fret.
Drop fret with bolt into
slotted retainer (fret
adjusts up or down to suit)
Important:
The fret retainer brackets are designed to
maintain the required space in front of the window to
allow the window to move and relieve during a hard
start.
It is very important to ensure this area in front
of the window is kept clear at all times.
Slip fret retainer
over thumbscrews
and tighten screws
