CONDENSING HEAT EXCHANGER

14  Reassemble the Condensing heat exchanger carrying out 

the removal operations in reverse order.

Ensure to tighten the nuts "H" - Figure 5.2 firmly.

5 .3  Cleaning

If there are deposits of dirt on the coil of the Condensing heat 

exchanger, clean with a bristle paintbrush and remove the dust 

with a hoover.

Warning: After cleaning or replacement as detailed 

above, it is deemed necessary to undertake a com-

bustion analysis as detailed in chapter "8 .3 Adjust-

ment" on page 22 section "8 GAS VALVE" on 

page 22 .

Figure 5 .4

 

Caution:

After any periodical servicing or disturbance the combustion 

chamber silicon seal "Q" Figure 5.4 and the Air-gas duct gasket 

(Figure 5.5) must be fully inspected and replaced at the discre-

tion of the service engineer.

After any disturbance to the chamber door seal the appliance 

must undergo a full analytical combustion performance check.

Remove any limescale from the detection electrode 

and replace it if worn .
