Vertical Damper Adjustment; Intake Air Shutter Adjustment; Glass Replacement - Heat & Glo MISSION-BAY Owner's Manual

I. Vertical Damper Adjustment
Refer to vent graph on Page 11. 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.
The vertical damper adjustment is located on the
Figure 8.17
right side of the appliance behind the side curtain. The damper
is centered towards the top of the appliance. Loosen screws
using a Phillips screwdriver.
Pivot the vertical damper adjuster in 1/4 in. increments, while
observing the flame activity.
Turn clockwise to open damper = less flame height and more
blue in flame color. Turn counterclockwise to close damper =
increased flame height and more yellow in flame color.
Make adjustment until flame size and activity suits your per-
sonal preference, and then re-tighten screws on adjustment
control.
NOTE: In the Commonwealth of Massachusetts, the word
damper shall be replaced with the words flue restrictor.

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 nut to lock in place.
