Installation of an Amana GUI

Examine the existing ducting to see if it needs replacement or if it will work with the new furnace. Replace any ducting necessary.

Position the Amana furnace on a level surface near to the electrical and gas supply lines. If you are replacing one furnace with another, it is best to place the new Amana furnace in the same location as the original.

Hire a certified natural gas technician to examine the incoming gas line to ensure it is prepared for installation to the new furnace and that there are no problems with the valve. Have the furnace connected by the technician to guarantee safe installation of the gas line.

Fit the main heat transfer duct with a collar and seal the connection with foil-backed tape. Attach the duct work to the transfer duct through the collar and tape this seam securely. Fit a collar into the air return hole on the Amana furnace and tape the seam. Attach the air return duct for the home into this collar and seal this seam with the tape.

Check the electrical circuit box to verify that the circuit for the furnace is off. Remove the electrical cowling on the side of the Amana furnace using a Phillips screwdriver. Connect the electrical and thermostat wiring based on the diagram on the inside of the electrical cowling and reattach the plate securely.

Turn on the electrical current at the main circuit box and ignite the pilot light. Test the operation of the new furnace by adjusting the thermostat and verifying that heat is passing through the ducts. Ensure that the furnace starts and stops properly when the desired temperature is reached on the thermostat.
