▪ Make sure the area is well ventilated. Do NOT block any ventilation openings.
▪ Make sure the unit is level.
▪ If the wall on which the unit is mounted is flammable, a non-flammable material
must be placed between the wall and the unit. Do the same for all locations
through which the flue piping passes.
▪ ONLY operate the gas boiler if a sufficient supply of combustion air is ensured. In
case of a concentric air/flue gas system dimensioned according to the
specifications of this manual, this is fulfilled automatically and there are no other
conditions for the equipment installation room. This method of operation applies
exclusively.
▪ Store flammable fluids and materials at least 1 meter away from the gas boiler.
▪ This gas boiler is NOT designed for room air dependent operation.
Do NOT install the unit in the following places:
▪ In potentially explosive atmospheres.
▪ In places where there is machinery that emits electromagnetic waves.
Electromagnetic waves may disturb the control system, and cause malfunction of
the equipment.
▪ In places where there is a risk of fire due to the leakage of flammable gases
(example: thinner or gasoline), carbon fibre, ignitable dust.
▪ In places where corrosive gas (example: sulphurous acid gas) is produced.
Corrosion of copper pipes or soldered parts may cause the refrigerant to leak.
▪ In bathrooms.
▪ In places where frost is possible. The ambient temperature around the gas boiler
should be >5°C.
If applicable. See the installation manual or installer reference guide of your
application for more information.
NOTICE
Make sure refrigerant piping installation complies with applicable legislation. In
Europe, EN378 is the applicable standard.
NOTICE
Make sure the field piping and connections are NOT subjected to stress.
WARNING
During tests, NEVER pressurize the product with a pressure higher than the
maximum allowable pressure (as indicated on the nameplate of the unit).
WARNING
Take sufficient precautions in case of refrigerant leakage. If refrigerant gas leaks,
ventilate the area immediately. Possible risks:
▪
Excessive refrigerant concentrations in a closed room can lead to oxygen
deficiency.
▪
Toxic gas might be produced if refrigerant gas comes into contact with fire.
