Refer to the 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 shutter is located on the underside of the 

appliance, on the right side.  To adjust the shutter, loosen 
the wingnut.. Retighten the wingnut after adjustment.

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.

The vertical damper adjustment is located on the 

right side of the unit behind the side curtain.  The damper is 
centered towards the top of the unit.

Make adjustment until flame size and activity suits your 
personal preference, and then retighten screws on 
adjustment control.

NOTE: In the Commonwealth of Massachusetts, the word 
damper shall be replaced with the words flue restrictor.

Loosen screws using a Phillips screwdriver. 

Pivot the vertical damper adjustor in 1/4 in. increments while 
observing the flame activity.

Turn clockwise to open the damper = less flame height and 
more blue in flame color.  

Turn counterclockwise to close damper = increased flame 
height and more yellow in flame color.
