old boiler, new vent

annieh Member Posts: 1
I have an older ( 20 years maybe ? )Utica Boiler that I need to pull the vent out of the chimney , along with the hot water heater vent and re vent them elsewhere.  Is it possible to power vent these through a sidewall?

Thank you.

    New vents:

    Surre. You can power vent them through a sidewall. But they must be separate and individual. You can't have one power venter for two appliances.

    do you have to do this? If the chimney just needs a liner, it's far less complicated to have one installed..................

    Sidewall vent

    You can sidewall vent a gas appliance if, it was previously certified as sidewall vented. You cannot legaly and whitout liability, sidewall an appliance that was not certified for sidewall venting. You cannot vent two appliances in the same sidewall vent, legaly!

    Yes S/S chimney liners are cheaper to solve a chimney issue, in most cases.

    Please find yourself a reputable and licensed contractor to propose the right solution with no fatal effects by monking around with venting!
