How do you pour fuel in the third example, where masonry surrounds the unit?

Before filling, make sure the burner is off. Do so by closing the shutter for 10 seconds prior to filling. To facilitate the filling process, remove the protective glass and place it in a safe area. Fill the burner compartment with Eco-Feu ethanol using the Easy-Pour Spout included with your unit. Screw the Easy-Pour Spout to the ethanol container. Make sure the Easy-Pour Spout valve is in the closed position. Place the tip of the spout directly inside the burner opening. Slowly, partially open the valve and fill the burner right up to the maximum marker, making sure not to exceed the maximum filling mark (MAX) indicated inside the burner. The burner should be filled to the max marker to light it. Once the fuel level has reached just below the Max marker, close the valve. Slowly remove the spout from inside the burner opening taking into consideration that there may be fuel left in the pouring spout. Once filled, put the protective glass back into position. In case of fuel spillage in the overflow container, remove the burner, wipe the overflow completely with a dry absorbent cloth and replace the burner into the overflow container before lighting the unit. By keeping the unit clean of any ethanol residue, it will prevent the ignition of residue outside of the burner when it is lit.
