A vent damper is provided to allow fine tuning of the draft. Too little draft will cause flames to be too long with black tips and too much draft will cause flames to be short and blue.
To adjust the damper, burn the unit on High 10 minutes or more. Adjust the vent damper to a posi- tion in the ranges listed below that produces the most desirable flame pattern. Note: 1 is less draft and 4 is maximum draft.
