Vertical Vent Baffle Installation
In applications without elbows (a straight vertical installation), the
use of a vertical vent baffle may be required. The vertical vent
baffle is the flat piece of painted steel with eight holes located in
the instruction envelope.
1. Locate and remove the two screw to the right of the flue open-
ing.
2. Verify the flue blockage requirements to steady the flame.
Note: 40 foot vertical requires maximum blockage. 10 foot
vertical requires minimum blockage.
3. Align vertical vent baffle holes with the holes in the firebox top
and secure vent baffle with the two screw in the same holes
they were removed from in step 1.
