Exhaust / Intake vent installation

Installation of the exhaust and intake chimney
pipe (chimney) shall be performed in a specified
method.
Incorrect installation of the exhaust and intake
chimney pipe (chimney) may lead to an exhaust
gas poisoning.
The connection points of the exhaust and intake
pipes shall be free from any leakage.
The exhaust gas, if flowing into the indoors, may
cause carbon oxide poisoning.
The air intake or the exhaust vent shall be
installed in the outdoors or a well-ventilated
place where the exhaust gas emitted from the
vent does not flow into the indoors.
The exhaust gas, if flowing into the indoors, may
cause carbon oxide poisoning.
Be sure to install the air intake and the exhaust
vent.
Failure of ventilation may lead to incomplete
combustion due to oxygen deficiency, which may
eventually result in carbon oxide poisoning.
The boiler of the forced exhaust type (FE) can
not employ the multiple exhaust ducts.
The reverse flow of the exhaust gas may cause
carbon oxide poisoning.
