REMOVING THE SCREEN
Pull the screen out of the support with pointed pliers. Blow out the support
with compressed air.
If necessary, carefully pierce with a wire.
The special tool has to be used to install the screen. The special tool is

position of the recess. The recess must be positioned at right angles (90°) to
the axis of the heater.
Newer screens do not have a recess.
Push the tool with the screen carefully as far as it will go, ensuring that the

In case of the shorter, new style screen (see image B) the position of the
screen to the vent hole has no reference. Ensure installation tool is completely
