1.
Fill the calorifier via the cold water input pipe.
2.
Carefully degas the DHW tank and the distribution network in
order to eliminate noises and hammering caused by trapped air
moving in the pipes during draw-off.
To do so:
- Fill it completely with water, leaving a hot water tap open.
- Only reclose this valve when the flow is regular and there are no
noises or hammering in the pipes.
- Then successively degas all the hot water pipes by opening the
corresponding valves.
3.
Check the safety devices (particularly the valve or safety unit),
referring to the instructions provided with these components.
During the heating process, a certain amount of water may
flow through the valve or safety unit; this is caused by
water expansion. This phenomenon is completely normal
and must in no event be hindered.
