In installations with an
approved flexible pipe
for LPG, pay special
attention to the
following.
• The pipe must comply with applicable
regulations.
• Avoid areas with heat emissions.
• Prevent the pipe from bending or being
pinched shut.
• The connections on both sides (gas valve
and other components) must comply with
the regulations of the country where the
heater is installed.
2.6 Air and flue gas ducts
The diameter of the pipe
connecting to the flue must
not be smaller than that of the pipe
connecting to the draft hood. After the draft
hood, there must be a vertical segment at
least half a meter long. The dimensions and
installation of the flues and the
tube connecting to them must
comply with current standards.
2.6.1 FUME EXHAUST SAFETY DEVICE
(fume thermostat)
• The water heater’s safety device ensures
the correct exhaust of flue gases;
THEREFORE DO NOT DEACTIVATE
IT OR CARRY OUT ANY OPERATION ON
IT.
• If the safety device cuts in when the water
heater is started, check the flue gas
outlet, checking the exhaust
with a cold mirror or with any suitable
and approved measuring device.
• In case of a fault, only use original
replacements, otherwise the safety device
may not work properly.
• Fume thermostat replacement must be
carried out by qualified technicians,
proceeding as follows:
- - Remove the faulty fume thermostat by
undoing the 2 fixing screws.
- - Install a new original thermostat.
- - Fix the fume thermostat in its place
without overtightening the screws.
- - Check its correct operation.
Remember to make an
air inlet opening in the
room where the water
heater is installed (as
required by the current
regulations).
If the above instructions
are not observed there
may be risk of
suffocation or poisoning
due to gas or fumes
escaping.
