F205P
For Home Owners
Maintenance routines
Checking the safety valves
F205P has three safety valves, one for the heating system
and two for the water heater.
The heating system safety valve (52) must be completely
tight, but the hot water safety valve (47) may release some
water after hot water has been used. This is because the
cold water which enters the water heater to replace the
hot water expands when heated, causing the pressure to
rise and the safety valve to open.
Safety valve (104) does not normally release water.
The safety valves must be checked regularly. Check one
valve at a time as follows:
1. Open the valve.
2. Check that water flows through the valve.
3. Close the valve.
4. The heating system may need to be refilled af-
ter checking the safety valve (52), see the section
”Commissioning and adjustment” – ”Filling the heat-
ing system”.
Cleaning the ventilation devices
The building’s ventilation devices should be cleaned regu-
larly with a small brush to keep the correct ventilation.
The device settings must not be changed.
Note! If you take down more than one ventilation device
for cleaning, do not mix them up.
Check that the ventilation opening (84), behind the lower
front cover, is not blocked. Clean if necessary.

The pressure gauge shows the pressure in the heating sys-
tem. The pressure should be between 0.5 and 1.5 bar.
