Fit the chimney cover. Empty the water heater if there is
any danger of frost.
If the heater will be shut down for a long period, close the
fast closing valve in the gas pipe. Close the gas cylinder
valve.

pump (main switch or the pump switch).
2. Open the hot water taps in the washroom and in
the 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 out (10 or 14 liters depending on the model).
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.
