MAKE THESE ADJUSTMENTS WHEN INSTALLING.
VERTICAL FLUE:

The arrow on flap at bottom of gate must line up with letter “V” on lower right part of gate. If it does not, remove flap, turn over and snap on to gate again.
Flap can be removed by inserting small screw driver at the back side of the gate between the gate and the flap, then pulling downward on flap.

INSTALLATION
Install barometric draft control using a 24 or 26 gauge 8” X 8” X 8” galvanized or black sheet metal Tee.
Use Spirit Level to make sure that the control does not lean forward or backward but instead is plumb in both directions, regardless of whether the flue is horizontal, vertical or sloping.
INITIAL SETTING OF BAROMETRIC CONTROL
Set the control at a maximum of .03 or as low a draft as will give good combustion and meet the requirements for heat. Turn adjustment weight
