Be cautious
Use ducts made of stainless steel or materials which are heat and water resistant.
If the gas flue ducts pass through walls made of flammable material, install incombustible boards
on the walls to prevent fire.
The ducts should be placed at a point at which you have easy access for maintenance.
If, due to unavoidable circumstances, you must install them in the roof space or a concealed area,
the ducts must be insulated with incombustible insulation. A minimum amount of space and ventilation
for maintenance must always be preserved.
You should use the ducts must be officially certified.
Warning

You should use the ducts must be officially certified.
Do not use flexible aluminum ducts.
The connection between the boiler and the exhaust gas duct must be fixed firmly
so that it cannot be separated by external factors.
Duct connections must be sealed using an O-ring and heat-resistant silicon
(except plaster bandage) and exhuast gas leakage must be checked.
Any damages caused by not installing the boiler in accordance with the recommendations
made herein are the installer’s responsibility.
