Should I insulate the fresh air intake?

Do not insulate the combustion air. This will allow the combustion air to warm somewhat. You should use at least eight feet of 4" metal pipe on an outside air intake. I consistently use twice that with good results.

    Should I insulate the fresh air intake?

    I have twenty feed of 4-inch steel ductwork that brings fresh air to my oil burner with a Fields Controls sleeve.

    Is it worth the money to insulate this pipe to prevent the heat drain?

    Is the boiler flame temperature any different when it is fed with 0* air versus 70* inside air? The thing I like is that the clothes dryer lint will no longer clog the burner vents.

    Probably not mandatory that you insulate it if you are not getting condensation on it, Combustion is better if the air is warmer-but if you insulate it won't the air stay colder???

    Yes, the insulation will make the air colder. So since there is no condensation, sounds like I should leave it alone.
