Nibe Fighter 200P - Cleaning the Ventilation Devices; Pressure Gauge; Checking the Safety Valves

LEK
The pressure gauge reading should be between the
initial pressure of the expansion vessel (normally 0.5
bar) and 1.5 bar (15 mvp). See Commissioning and
adjusting.

For Home Owners

FIGHTER 200P has three safety valves, one for the
heating system and two for the water heater.
The heating system safety valve (52) must be com-
pletely 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:
■ Open the valve.
■ Check that water flows through the valve.
■ Close the valve.
■ The heating system may need to be refilled after
checking the safety valve (52), see the section
”Commissioning and adjustment” – ”Filling the
heating system”.
The building’s ventilation devices should be cleaned
regularly with a small brush to keep the correct venti-
lation. 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.
