If the screw is in an area that is impossible to put a bucket or small tray under, use a flexible tubing just big enough to fit over the bleed screw. Place the tube over the bleed screw and direct it to an area where you can fit the tray or bucket.
Keep your pliers or wrench on the screw ready to tighten it. This will also ensure the screw remains in place, if you did loosen it too much. If the furnace cycle ends before the air and fuel mixture stops sputtering, you’ll need to push the reset button again to continue the bleed process until the furnace pushes out all the air from the line. Some furnaces may have a lockout system that won’t allow you to reset more than one or two times. If this happens, you can override the lockout by holding the reset button in until the furnace kicks in again.
