before you begin your adjustment. If your installation falls
within the range of the gray shaded area of graph, it may be
necessary to make an adjustment to the vertical damper to
improve the flame appearance in your appliance.
Figure 8.34 The shutter is located on the underside of the
appliance, on the right side. To adjust the shutter, loosen
the wingnut..
Moving the shutter bolt to the right closes the shutter. Moving
the shutter bolt to the left, will open the shutter. Opening the
shutter causes flames to become shorter and blue. Closing
the shutter creates taller orange/yellow flames.
NOTE: Do not close so much as to cause a sooty flame.
Improper adjustment can cause sooting in the firebox and/
or on the outside of a house with a horizontal termination.
After adjustment, tighten wingnut to lock in place.
