The small white screw next to the Ignighter light on the harman accentra insert is used to adjust the combustion fan to make up for voltage irregularity. So If I turn it clockwise would I would be turning the combustion speed down by adding resistance?
So I should keep it all the way to the left, or counter-clockwise to get most combustion fan voltage? The manual is very vague on this.
