Refer to Vent Graph on page 27. If your installation
falls within the range of the grey shaded area of
graph, it may be necessary to make an adjustment to
the vertical damper to improve the flame appearance
in your stove.
TOP VENT INSTALLATIONS:
Locate the damper adjustment control at the rear of
stove behind the rear vent acess panel. See Fig. 1
REAR VENT INSTALLATIONS:
Locate the damper adjustment control on the top of
the stove beneath the grill plate. See Fig. 2
Make adjustment:
Loosen screw using a Phillips screwdriver.
Pivot the vertical damper adjustor in 1/4” increments
while observing the flame activity.
Turn counter-clockwise to open damper = less flame
height and more blue in flame color.
Turn clockwise to close damper = increased flame
height and more yellow in flame color.
Make adjustment until flame size and activity suits
your personal preference, and then re-tighten screw
on adjustment control. Reattach rear vent access
panel (rear vent) OR grill plate (top vent).
