    Common venting for mod- con boilers?

    Is it possible to combine venting of multiple mod-con-combi boilers?  They would handle separate spaces in an apartment building.  The building is a historic structure, which makes the venting a tough issue.  Thanks

    yes, if

    The boiler manufacturer supports it.

    Ditto

    SWEI is correct. It has to do with the listing.

    If the manufacturer had it tested by UL or CSA with common venting then yes. If not then no. Check with your manufacturer.
