This package consists of a 3D interactive boiler and a set of control buttons.

You can examine the boiler by clicking in the boiler view and dragging your mouse in any direction. In the boiler view, you can also zoom by clicking on the white pointer located to the right of the boiler view and dragging the mouse up (zoom in) or down (zoom out).

The navigation buttons are as follows:
Boiler Components - Takes you back to the full list of components associated with this boiler.
Instruction Manual - Launches a PDF of the manufacturer's manual for this boiler.
Help - Launches this User Guide
Remove - Shows the steps involved in disassembling the currently selected component.
Replace - Shows the steps involved in reassembling the currently selected component.
Components - Shows the individual parts of the selected boiler component. In this mode, you can click on any of the parts in the list to highlight the physical part in the boiler view and discover additional information about that part.

The 'Remove', 'Replace' and 'Components' options are available only after a boiler component has been selected as they relate to the selection. When a component is selected and you are in the 'Remove' or 'Replace' modes, you can view a step by clicking on the appropriate instruction in the list. The selected step is then animated in the boiler view and accompanied by audio.

The 'Stop', 'Play', and 'Play All' buttons below the virtual boiler become available when a component is selected and you are in the 'Remove' or 'Replace' modes. Their functions are as follows:
Stop - stop the currently playing step.
Play - play the current step in the instruction list.
Play All - play all the steps in the instruction list from the beginning.
