New Heater Vibration


My heater died Christmas weekend and had to have a new one installed.

The unit was replaced by a Meridian 100,000 BTU Gas furnace.

The unit heats the house nicely but I am noticing one problem that was not in existance with my old Lenox unit.

TGhe duct work traveling vertical from the unit vibrates a lot - its seems almost as if the sides of the duct work push in and out when the unit is running. Also affected is the horizontal branched off duct work in close proximity to the unit.

Seems like everything else is working fine but the vibration can actually be heard on the first floor in the wall also ust above the heater.

Any idea what might be causing this?

Was any of the duct work changed or modified?

Call the installer back and tell him to fix it, it never made those noises before. He may have to add a canvas collar and vibration pads under the unit.

No the duct work was not touched except where it connects into the heating unit
