BALANCED FLUE PRINCIPAL
In practice it is almost impossible to achieve exact
balance between the pressures on the air inlet and flue
outlet of a balanced flue terminal. In order to avoid the
possibility of reverse fluing the flue terminal design is
always biased to provide slightly higher pressure on the
air inlet.
The flue terminal is designed and tested to operate with
winds directed at the side or front of the water heater. If
the wind comes from the behind the water heater, the
operation of the flue terminal is unpredictable and may
result in problems such as flame roll out from the
combustion chamber, sooting of the primary flue and
stainless steel super flue and/or pilot outage.
For this reason the water heater must be installed
against an external wall.
