Caution!
Possible material damage caused by loose-
ning or retightening the screws!
The primary heat exchanger may become
damaged.
>
Do neither attempt to loosen nor retighten
the four screws (1).
With the burner and fan assembly removed it is now
possible to inspect the main heat exchanger (

Remove any loose deposits from the heating spirals
(

) using a soft brush and jet of water (ensure that
water is kept away from all electrical components.
Any water used to clean the main heat exchanger will
drain through the condensate trap). Avoid pointing
the water jet directly at the insulating surface (

) on
the back of the heat exchanger.
If required the heat exchanger can be cleaned using reg-
ular vinegar.
