To remove the inverted U-shaped metal door from the glass on the Mendota DXV-42 fireplace:

1. Use the latch spring tool to insert the hook end through the hole in the left latch spring and turn until unlatched from the glass.
2. Repeat step 1 on the right latch spring.
3. Pull the bottom slightly away from the front and lift the glass assembly up until it clears the upper tabs.
4. The door is now free from the unit.

Always check the glass gasket condition and seal when reinstalling the glass door.
