For the installation of smoke exhaust pipe, please pay attention the
following matters :
The water heater must be installed with smoke exhaust pipe
during the use. The pipe dimension refers to the ‘Specification’
section in this manual book. The smoke exhaust pipe should be
installed according to the requirements in this manual book.
Determine the length of the corrugated pipe as needed, but the
total height of the pipe should be more than 2 m, and the
horizontal length is no more than 3 m. The vertice quantity
should be no more than 2, and the angle is no less than 90° to
reduce the smoke exhaust resistance.
Fasten the corrugated pipe and the smoke vent of the water
heater with clamps to prevent exhaust gas being vented inside
the room.
Tilt the smoke exhaust pipe 3° outward and downward to
facilitate the outflow of condensate water.
Cover the smoke exhaust pipe with heat-insulating and fire-
proof materials which its thickness must be more than 20 mm.
Cover the pipe that is installed around the flammable wall.
Do not hide the smoke exhaust pipe inside the ceiling.
Otherwise, wrap up the pipe with heat-insulating material that
has more than 20 mm thickness. Make a distance more than
150 mm between the smoke exhaust pipe and flammable
materials (such as ceiling and furniture).
For maintenance, do not use cement to fill the gap between
smoke exhaust pipe and the access hole of the pipe on the
wall.
