RESTRICTING VERTICAL VENTS
Vertical installations running longer than 10 feet may dis- play a very active flame. If this appearance is not desirable, remove the brick baffle from the firebox, exposing the flue gas outlet openings. Bend the restrictor plates up (from their normal opening of 45°) into the flue openings. Re- place the brick baffle. This reduces the velocity of the ex- haust gases, slowing down the flame pattern and creating a more traditional gentle appearance. Specific instructions are shown in "Trouble Shooting".
