kitchen.
3. Open the security/drainage valve (14).
4. Then drain the water heater using the safety valve (14)
towards the outside. Check to make sure that all water runs

Maintenance
When you want to remove scale from the water heater, use
wine vinegar or formic acid, putting it into the appliance
through the water inlet. Allow the product to act and then
clean the water heater thoroughly with fresh water. We
recommend that you use « Certisil » to degerminate the
appliance since other products, and particularly products
containing chlorine, are unsuitable.
To prevent the spread of micro-organisms, you should heat
the water heater regularly to 70ºC.
the water contained in the tank is not drinking
water.
Fuses
The appliance’s fuse is located
on the appliance’s electronic
command unit. Only replace the
fuse with an identical model and
rating of fuse: 1.6 A (slow blow).
Your gas fittings must be checked regularly by a registered
workshop. The owner is responsible for having these
checks done.
