When using a water heater for combination space
and potable water heating, the instructions provided
in this manual and with the air-handling unit must be

2) When used as a dual purpose water heater,
it must not be connected to any system that
has been previously used for non-potable water
heating. This includes any piping because, in all
probability, existing piping would have been, in
the past, treated with chemicals for cleaning or
sealing the system.
3) If this water heater is to be used for space
heating, make sure that all safety codes are
respected. Pay special attention to safety valve
pressure and expansion tanks.
