PRODUCT DESIGN General Operation This GUIC/GCIC furnace is equipped with an electronic ignition device to light the burners and an induced draft blower to exhaust combustion products. Accessibility Clearances (Minimum) MINIMUM CLEARANCES TO COMBUSTIBLE MATERIALS (INCHES) UPFLOW An interlock switch prevents furnace operation if the blower door is not in place. Keep the blower access doors in place except for inspection and maintenance.
