Water Inhibitor Concentration; Checking The Condensate Drain Pipe; Checking The Low Water Cutoff; Setting The Boiler Chimney Sweep Function - Biasi Riva Advance Combi Installation & Operation Instructions

17. Annual Maintenance Cont.
Where chemical products are used the level of water treatment should be checked on an
annual basis and re treated after full or partial drain down.
A conductivity meter can be used to check the correct concentration of inhibitor in the heating
water. See the section 15.1 of this handbook.
The condensate drain system should be
checked yearly during a service.
Check:
• That no solid deposits have formed, if so
remove them.
That the condensate drain piping is not
•
clogged, if so clear the clog.
Removal
Unscrew the plug D to clean inside the pipe.
Remove the forks E and remove the
•
condensate trap A moving it downwards
(Fig. 17.8).
• If a low water cutoff is installed on a system, it's function should be checked as part of
the yearly service. Refer to the low water cutoff manufacturers instructions for
maintenance and testing.
With the boiler set in chimney sweep
mode, it is possible to exclude some boiler
automatic functions making check and
control operations easier.

in Figure 17.9.
• Electrically power the boiler, the following
will appear on the LCD display.
• To enter Chimney cleaning mode, enter
programming by pressing the reset
