32–35.
Adjust Aeration (if necessary)
Light the
fi
re and allow the unit to warm up for 10–15
minutes to evaluate the
fl
ame picture. Burners are
equipped with an adjustable shutter to control primary
aeration. See the
fi
gures below. The shutters are
factory-set to an aeration gap which will give optimum
performance for the vast majority of installations.
Depending of 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, liners and window installed and evaluating the
fl
ame picture after a 15-minute warm-up.
Pull or push the aeration lever at the bottom front left
corner of the unit to open or close the air shutter. The
shutter is visible at the left hand end of the burner.
Increasing aeration (open)
will cause the
fl
ames to
appear more transparent and blue showing more
ceramic e
ff
ects glow.
Decreasing aeration (close)
will cause the
fl
ames to
appear more yellow or orange showing less ceramic
e
ff
ects glow.
Too little aeration may result in black carbon forming
and dropping into the
fi
rebox.
Air Shutter
To access the air shutter, very carefully remove the
ceramic burner. The air shutter is located under the
burner, at the back, as shown.
1. Remove the screw
fi
xing the rear of the burner to
the manifold bracket as indicated.
2. Grab the burner and gently pull up the rear
fi
rst
while pushing back and unhooking the front tabs
from their retaining lances.
Be careful not to hook
the pilot hood as you pull the burner up
.
3. Loosen the air shutter nuts, adjust and re-tighten.
4. To re-install the burner, insert the burner front tabs
fi
rst in the lances then lower the rear of the burner.
Note: Ensure the front of the
burner is well hooked when re-
installling!
Again, be careful not to hook
the pilot hood when
fi
tting the
burner over the pilot.
5. Secure the burner to the manifold bracket at the
rear with the screw.
