    I have a 40 k btu Mendota I have been using for a few months now, but have a question about adjusting the flame for maximum efficiency.
    The manufacturers instructions are vague. The say to set shutter valve to from 1/8 to 1/4". At that setting, the flame is mostly orange, and the color doesn't seem to change much as I open the shutter further.
    I don't seem to have a lot of sooting on the glass. How do I adjust for max efficiency? Give me a good plan for adjusting the flame..
    Thank you

    If you want maximum efficiency, open the air shutter completely.
    A BLUE flame is burning cleaner & is more efficient than a YELLOW one.
    Take a look as a gas furnace or boiler...The only
    time the flame is YELLOW is when you disturb dust or dirt & it burns up.
    Unfortnately, wood fires burn YELLOW & that's what gas fireplaces are meant to represent...
    If you want it to look REALISTIC, that's another issue...
    The flames should be YELLOW at the top & BLUE towards the burner holes...
    If your flames appear ORANGE, they're starving for O2 & will soot up both your logs & glass...
