Gas: Use a licensed professional to connect the gas line. Check for leaks using a soapy water solution.
Step 4: Ductwork and Airflow
Proper duct sizing is essential for optimal airflow. Use a duct calculator to determine the correct sizes. The GR9S920603BN has a 1200 CFM blower, so ensure your ducts can handle the airflow.
