    All my burners are soot free, burning to maximum efficiency, and pose no threats to human life.

    Maybe we have 2 different perspectives on burning properly.

    I use the proper tools and test equipment to setup my burners for maximum efficiency and safety

    You didn’t say what code asked for.

    You said for it to burn properly.

    Just saying

    I have no idea what you are trying to say in a few of your posts.

    Carry on

    OK, I'll rephrase. A residential oil boiler/furnace burns 1 gal of #2 oil in 1 hour. How many "total" Cubic Feet of air is needed for the oil combustion and draft purposes. Lets go from the least efficient 1970 unit up to todays more efficient systems.

    Then ,what is the same "total air" needed for 1 Cu Ft. of Natural Gas.?

    The requirements are about 15 cubic feet of combustion air and 15 cubic feet of dilution air for every cubic foot of gas burned.

    Is that the same thing as saying that a 100,000btu boiler/furnace (as in your example) needs 3000 CuFt of "combustion air",,,, every hour!??!

    I'll point you in the right direction sir. Since a cubic foot of natural gas contains about one thousand BTUs, a furnace that fires at the rate of 100,000 BTUs per hour would use 100 cubic feet of gas if it fired constantly for 60 minutes. This means that it would use two cubic feet of gas per minute. We need about 60 cubic feet of air per minute (30 x 2) to ensure proper operation of this furnace.

    I am talking 100k btu "in" and about 80K btu out.

    Not sure about the "two CuFt a minute of gas thing"
