A horizontal balanced flue must be installed when
the wall adjoining the water heater is on outside wall
in a well ventilated location. The water heater instal-
led in this way possesses a sealed combustion cir-
cuit, completely independent of the ventilation
circuit for the rooms.
The flue may be mounted to the right, to the left, or
directly behind the water heater.
The balanced flue outlet must be located at least
0.4 m from any opening window and 0.6 m from any
air ventilation opening (see regulations). Two balan-
ced flue outlets (from two distinct adjacent THR
units) must be at least 0.6 m apart.
The flue gas exhaust tube must slope towards the
outside at 1 cm per meter to avoid accumulation of
rain water in the vent-air intake system.
