How to replace the heat exchanger in my American Standard Platinum 95 Gas Furnace?
Replacing the heat exchanger in your American Standard Platinum 95 Gas Furnace is a complex and potentially hazardous task that should only be undertaken by a licensed and experienced HVAC technician. The heat exchanger is a critical component responsible for transferring heat from the burner to the air that circulates through your home. Replacing it requires specialized knowledge and tools. Here's a general overview of the steps involved, but please note that this is not a DIY project:
1. Safety Precautions:
* Safety is paramount when working with gas appliances. Turn off the gas supply to the furnace at the gas valve and ensure the power is turned off at the circuit breaker.
* Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
2. Gather Tools and Materials:
* Collect the necessary tools and materials, which may include a replacement heat exchanger, a socket set, wrenches, screwdrivers, pliers, pipe cutters, tubing cutter, tubing flaring tool, pipe thread sealant, and a multimeter for electrical testing.
3. Disconnect Power and Gas:
* Double-check that both the gas supply and electrical power are turned off.
* Shut off the gas valve supplying the furnace.
4. Access the Heat Exchanger:
* Access the heat exchanger by removing the access panels and any obstructions that prevent access. The heat exchanger is typically located within the furnace's cabinet.
5. Remove the Old Heat Exchanger:
* Carefully disconnect the gas supply line from the old heat exchanger.
* Remove the flue venting, which is typically connected to the heat exchanger.
* Disconnect any electrical connections that may be present, such as igniter or flame sensor wires.
* Unbolt and remove the old heat exchanger from its housing. Be cautious not to damage any nearby components.
6. Install the New Heat Exchanger:
* Position the new heat exchanger in place, aligning it with the mounting brackets or housing. * Secure it with the appropriate bolts or fasteners.
* Reconnect the gas supply line, ensuring that all connections are tight and sealed properly with pipe thread sealant.
* Reattach the flue venting, making sure it is correctly aligned and securely fastened.
* Reconnect any electrical wires that were disconnected during removal.
7. Pressure Test and Gas Leak Check:
* Perform a gas leak check to ensure there are no gas leaks in the connections.
* Pressure test the gas line to verify that the system is airtight.
8. Inspect and Clean:
* Inspect the new heat exchanger for any signs of damage or defects.
* Clean the heat exchanger thoroughly to remove any dirt or debris that may have accumulated during installation.
9. Test the Furnace:
* Turn on the gas supply and electrical power.
* Test the furnace by setting your thermostat to the desired temperature and running the furnace. Observe its operation to ensure it is functioning correctly. Listen for unusual noises or combustion irregularities.
10. Monitor for Proper Operation:
* Check that the furnace continues to operate smoothly, providing heat without any issues or unusual odors.
11. Documentation:
* Keep records of the replacement, including the date, the make and model of the new heat exchanger, and details of the installation.
12. Professional Inspection:
* Consider having a qualified HVAC technician inspect the installation to ensure it meets safety and code requirements. They can also perform combustion analysis and verify that the furnace is operating optimally.
In conclusion, replacing the heat exchanger in your American Standard Platinum 95 Gas Furnace is a highly specialized task that should only be performed by a licensed HVAC technician. It involves working with gas connections, electrical components, and precise installation procedures. Incorrect installation can result in safety hazards, inefficiency, and damage to your furnace. Always consult a qualified HVAC professional to ensure a successful and safe heat exchanger replacement, and to ensure your furnace continues to operate efficiently and safely.
