Generated explanation

The illustration shows a horizontal gas-fired furnace installed beneath wood framing in a space with limited headroom. Return air enters from the left through an air filter and is moved by the blower toward the heat exchanger and the supply duct on the right. Gas burners are shown beneath the heat exchanger, with a gas valve connected to the burner piping. A vent connector rises from the heat exchanger area and turns horizontally to the left. The drawing identifies the principal components and airflow direction without depicting a specific defect.
