    Old Mars Gravity Feed Furnace - help - draft diverter

    We have just purchased a house with a Mars Gravity Feed Furnace.
    I am told that it needs a draft diverter and I wonder where I can get one
    as this is a VERY old furnace. Any help out there??

    Pics would be nice

    Some of those had a Round diverter that would be vertical in it orientation

    Other Gravity had 90 degree draft diverter when flue gas would enter the back of diverter
    and exit the top. I have had those made in the past.

    So a pic or a drawing of the diverter and maybe you could have it made by someone and installed also by them

    Happy New Year

    take a pic, get a local sheet metal place to make an EXACT copy of it. they should be able to come and measure. I've had one draft hood made up for an old lady who loves her gravity furnace. 355k btu for 750 sq ft 1800s 1.5 stories

    The problem is that the prior owner REMOVED the diverter and I do not know what it
    looked like. I believe that it was on the line that ran from the gas shut off valve to the gas input
    line which runs outside of the furnace down at floor level. The current line there is bright yellow and looks reasonably new, so I believe that is where it once was..I need to know what was originally there in order to copy it. Does anyone have an image of an old diverter from a Mars Gravity Feed
    Size No. 400. 70,000 btu? I have searched the web with no success.

    Since this is a safety issue, I think I'd be talking to a local pro not surfing the net for an item you won't find for a nearly 100 year old furnace.

    the easiest way is to upgrade it, and put the old furnace into a museum.
