5 Cleaning and maintaining the <strong>HDG</strong> <strong>Navora</strong> – How to proceed<br />
Inspecting the heat exchanger cleaning system<br />
1. Allow the fire in the boiler to burn out.<br />
The operating status of the <strong>HDG</strong> <strong>Navora</strong> must be indicated with<br />
“Heat production off” in the display of the <strong>HDG</strong> Lambda<br />
Control.<br />
✎ See section “4.1 Overview of the controls and display<br />
components” in chapter “4 Using the <strong>HDG</strong> <strong>Navora</strong> Wood Boiler”.<br />
Caution!<br />
Danger of burns from hot surfaces.<br />
The surfaces of the boiler can be hot. Even when turned off, they<br />
only cool down slowly.<br />
Do not start with the maintenance work until the surfaces have<br />
cooled down.<br />
