Oil to Gas conversion boiler - need to remove chimney

in Gas Heating
we converted our axeman anderson boiler (model #87NPO) with a Carlin Ez-Gas burner and it is currently vented through the existing chimney with a stainless liner. My issue is that there was an addition constructed before we moved in and we would like to move the chimney to put a hallway in.
Can i move the chimney to the side of the hallway with double wall stainless pipe? i could come straight out with a 45 to a 90 and straight up from basement through main floor then through attic and then the roof. I could also go the powervent route as well out the side of the house @10'. but would prefer to go out the roof. i am just not sure what i can do and what i cant.

thanks

    Check with your local building inspector or other authority having jurisdiction. Codes -- and local interpretations of them -- differ.

    And if you do find you can remove the chimney -- or just move it -- have a qualified individual check and make sure that you won't cause structural problems.

    double wall vent is code in most towns, check yours to find out, make sure it is lined with insulation. i would check the draft after installing, might have to add pipe up top to get your .05 draft after breach,...all that for a hall way, your brave, also wouldnt use powervent on a gas fired burner!!!!! the draft is to strong for gas fired equipment

    this is a good reference, you will need a tool to measure the draft, a manonamer or draftrite, anywhere around negative .02 and .05 is good and thats it , connect flue form boiler to chimney , drill hole 6 inches from top of boiler in the flue for the test , fire boiler and see what you got if you dont get that negative pressure youll have to add a piece 2 ft piece of double wall pipe to the top of your chimney till you get that negative .02 to .05
